Watlow EZ-ZONE® PM Integrated Controller • 2 • Chapter 1 Overview

Chapter 1: Overview

The EZ-ZONE® PM takes the pain out of solving

your thermal loop requirements.

Watlow’s EZ -ZONE® PM controllers offer options

to reduce system complexity and the cost of control-

loop ownership. You can order the EZ-ZONE® PM as

a PID controller or an over-under limit controller, or

you can combine both functions in the PM Integrat-

ed Limit Controller. You now have the option to in-

tegrate a high-amperage power controller output, an

over-under limit controller and a high-performance

PID controller all in space-saving, panel-mount

packages. You can also select from a number of se-

rial communications options to help you manage sys-

tem performance.

It just got a whole lot easier to solve the ther-

mal requirements of your system. Because the EZ-

ZONE® PM controllers are highly scalable, you only

pay for what you need. So if you are looking for a

PID controller, an over-under limit controller or an

integrated controller, the EZ-ZONE® PM is the an-

swer.

Watlow EZ-ZONE® PM Integrated Controller • 3 • Chapter 1 Overview

A Conceptual View of the PM

The flexibility of the PM’s software and hardware al-

lows a large range of configurations. Acquiring a bet-

ter understanding of the controller’s overall function-

ality and capabilities while at the same time plan-

ning out how the controller can be used will deliver

maximum effectiveness in your application.

It is useful to think of the controller in three

parts: inputs; procedures; and outputs. Information

flows from an input to a procedure to an output when

the controller is properly configured. A single PM

controller can carry out several procedures at the

same time, for instance closed-loop control, monitor-

ing for several different alarm situations and oper-

ating switched devices, such as lights and motors.

Each process needs to be thought out carefully and

the controller’s inputs, procedures and outputs set up

properly.

Inputs

The inputs provide the information that any given

programmed procedure can act upon. In a simple

form, this information may come from an operator

pushing a button or as part of a more complex pro-

cedure it may represent a remote set point being re-

ceived from another controller.

Each analog input typically uses a thermocouple

or RTD to read the temperature of something. It can

also read volts, current or resistance, allowing it to

use various devices to read humidity, air pressure,

operator inputs and others values. The settings in

the Analog Input Menu (Setup Page) for each analog

input must be configured to match the device con-

nected to that input.

Each digital input reads whether a device is active

or inactive. A PM with digital input-output hardware

includes two sets of terminals each of which can be

used as either an input or an output. Each pair of

terminals must be configured to function as either

an input or output with the Direction parameter in

the Digital Input/Output Menu (Setup Page).

The Function or EZ Key on the front panel of the

PM also operates as a digital input by toggling the

function assigned to it in the Digital Input Function

parameter in the Function Key Menu (Setup Page).

Functions

Functions use input signals to calculate a value. A

function may be as simple as reading a digital input

to set a state to true or false, or reading a tempera-

ture to set an alarm state to on or off. Or, it could

compare the temperature of a process to the set point

and calculate the optimal power for a heater.

To set up a function, it’s important to tell it what

source, or instance, to use. For example, an alarm

may be set to respond to either analog input 1 or 2

(instance 1 or 2, respectively).

Keep in mind that a function is a user-pro-

grammed internal process that does not execute any

action outside of the controller. To have any effect

outside of the controller, an output must be config-

ured to respond to a function.

Outputs

Outputs can perform various functions or actions in

response to information provided by a function, such

as operating a heater; turning a light on or off; un-

locking a door; or turning on a buzzer.

Assign an output to a Function in the Output

Menu or Digital Input/Output Menu. Then select

which instance of that function will drive the select-

ed output. For example, you might assign an output

to respond to alarm 4 (instance 4) or to retransmit

the value of analog input 2 (instance 2).

You can assign more than one output to respond

to a single instance of a function. For example, alarm

2 could be used to trigger a light connected to output

1 and a siren connected to digital output 5.

Input Events and Output Events

Input events are internal states that are set by the

digital inputs. Digital input 5 provides the state of

input event 1, and digital input 6 provides the state

of input event 2. Wait for Event steps in profiles

are triggered by these events. The setting of Digital

Input Function (Setup Page, Digital Input/Output

Menu) does not change the relationship between the

input and the event, so take care not to configure the

function in a way that would conflict with a profile

that uses an input event. An input will still control

the input event state, even if Digital Input Function

is set to None.

Output events are internal states that can only be

set by profile steps. Outputs 1 through 4 can be con-

figured to respond to output events.

Installation

case

retention collar

panel

bezel

gasket

1. Make the panel cutout using the mounting tem-

plate dimensions in this chapter.

Insert the case assembly into the panel cutout.

2. While pressing the case assembly firmly against

the panel, slide the mounting collar over the back

of the controller.

If the installation does not require a NEMA 4X

seal, slide the mounting collar up to the back of

the panel tight enough to eliminate the spacing

between the gasket and the panel.

Slide the mounting collar over

the back of the controller.

Place the blade of a screw-

driver in the notch of the

mounting collar assembly.

3. For a NEMA 4X (UL50, IP66) seal, place the

blade of a screwdriver in the notch of the mount-

ing collar assembly and push toward the panel

while applying pressure to the face of the control-

ler. Don't be afraid to apply enough pressure to

properly install the controller. The seal system is

compressed more by mating the mounting collar

tighter to the front panel (see pictures above). If

you can move the case assembly back and forth

in the cutout, you do not have a proper seal.

The tabs on each side of the mounting collar have

teeth that latch into the ridges on the sides of the

controller. Each tooth is staggered at a different

depth from the front so that only one of the tabs,

on each side, is locked onto the ridges at a time.

Note: There is a graduated measurement difference between

the upper and lower half of the display to the panel. In order to

meet the seal requirements mentioned above, ensure that the

distance from the front of the top half of the display to the panel

is 16 mm (0.630 in.) or less, and the distance from the front of

the bottom half and the panel is 13.3 mm (0.525 in.) or less.

Removing the Mounted Controller from Its Case

1. From the controller's face, pull out the tab on

each side until you hear it click.

Pull out the tab on each side

until you hear it click.

Grab the unit above and below

the face and pull forward.

2. Once the sides are released, grab the unit above

and below the face with two hands and pull the

unit out.

If it is difficult to pull the unit out, remove the

connectors from the back of the controller. This

should make it easier to remove.

ÓWarning:

• This equipment is suitable for use in class 1, div. 2, Groups

A, B, C and D or Non-Hazardous locations only. Temperature

ment unless power has been switched off or the area is known

to be nonhazardous.

Watlow EZ-ZONE® PM Integrated Controller • 10 • Chapter 2 Install and Wire

Returning the Controller to its Case

1. Ensure that the orientation of the controller is

correct and slide it back into the housing.

Note: The controller is keyed so if it feels that it will not

slide back in do not force it. Check the orientation again

and reinsert after correcting.

2. Using your thumbs push on either side of the con-

troller until both latches click.

Chemical Compatibility

This product is compatible with acids, weak alkalis,

alcohols, gamma radiation and ultraviolet radiation.

Default Home Page

The Home Page is a customized list of as many as 20

parameters that can be configured and changed in

the Custom Menu [ CUSt] (Factory Page). The default

list of nine parameters below includes the Active

Process Value (value in upper display) and Active Set

Point (value in lower display). The Attention [Attn]

parameter appears only if there is an active message.

An active message could be a reported error, for ex-

ample, [C;Er1] (Current Error), or it could be for in-

formation only, for example, [tUN1] (Autotuning).

Use the Advance Key ‰ to step through the other

parameters. The parameter prompt will appear in

the lower display, and the parameter value will ap-

pear in the upper display. You can use the Up ¿ and

Down ¯ keys to change the value of read-write pa-

rameters, just as you would in any other menu.

If Control Mode is set to Auto, the process value

is in the upper display and the Closed Loop Set Point

(read-write) is in the lower display.

If a profile is running, the process value is in the

upper display and the Target Set Point (read only) is

in the lower display.

If Control Mode is set to Manual, the process val-

ue is in the upper display and the output power level

(read-write) is in the lower display.

If Control Mode is set to Off, the process value is

in the upper display and [`oFF] (read only) is in the

lower display.

If a sensor failure has occurred, [----] is in the

upper display and the output power level (read-write)

is in the lower display.

Changing the Set Point

You can change the set point by using the Up ¿ and

Down ¯ keys, when a profile is not running.

If the set point is displayed and the % indicator is

lit, the controller is in open-loop (manual) mode.

Note: Avoid continuous writes within loops. Excessive writes to

EEPROM will cause premature EEPROM failure. The EEPROM is

rated for 1,000,000 writes.

Navigating the Profiling Page Note:

Some of these menus and parameters may not appear,

depending on the controller's options. See model num-

ber information in the Appendix for more information.

If there is only one instance of a menu, no submenus

will appear.

Watlow EZ-ZONE® PM Integrated Controller • 46 • Chapter 7 Profiling Page

The Profiling Page allows you to enter your ramp

and soak profile information.

To go to the Profiling Page from the Home Page,

press the Advance Key ‰ for three seconds, until

[ProF] appears in the lower display and the pro-

file number appears in the upper display. Press

the Up ¿ or Down ¯ key to change to another pro-

file.

• Press the Advance Key ‰ to move to the selected

profile's first step.

• Press the Up ¿ or Down ¯ keys to move

through the steps.

• Press the Advance Key ‰ to move through the

selected step's settings.

• Press the Up ¿ or Down ¯ keys to change the

step's settings.

• Press the Infinity Key ˆ at any time to return

to the step number prompt.

• Press the Infinity Key ˆ again to return to the

profile number prompt.

• From any point press and hold the Infinity Key

ˆ for two seconds to return to the Home Page.

Note: Changes made to profile parameters in the Profiling

Pages will be saved and will also have an immediate impact

on the running profile.

Some parameters in the Profile Status Menu can be changed

for the currently running profile, but should only be changed

by knowledgeable personnel and with caution. Changing pa-

rameters via the Profile Status Menu will not change the stored

profile but will have an immediate impact on the profile that is

running.

How to Start a Profile

After defining the profile follow the steps below to

run the profile:

1. From the Home Page push the Advance Key ‰

repeatedly until Profile Start [P;St1] appears in

the lower display.

2. Use the Up ¿ or Down ¯ key to choose the file

or step number within a profile where you want

the profile to begin running.

3. Press the Advance Key ‰. This takes you to

Profile Action [P;AC1], where you can select the

appropriate action.

• [none] No action

• [ProF] Begin execution from first step of the

specified profile number, whether it exists or not.

• [PAUS] Pause the currently running profile.

• [rESU] Resume running the profile from the

previously paused step.

• [`End] End the profile.

• [StEP] Begin running the profile from the spec-

ified step number.

Note: Avoid continuous writes within loops. Excessive writes to

EEPROM will cause premature EEPROM failure. The EEPROM

is rated for 1,000,000 writes.

Watlow EZ-ZONE® PM Integrated Controller • 54 • Chapter 9 Features

Saving and Restoring User Settings

Recording setup and operations parameter settings

for future reference is very important. If you uninten-

tionally change these, you will need to program the

correct settings back into the controller to return the

equipment to operational condition.

After you program the controller and verify

proper operation, use User Save Set [USr;S] (Fac-

tory Page, Diagnostics Menu) to save the settings

into either of two files in a special section of memory.

If the settings in the controller are altered and you

want to return the controller to the saved values, use

User Restore Set [USr;r] (Factory Page, Diagnostics

Menu) to recall one of the saved settings.

A digital input or the Function Key can also be

configured to restore parameters.

Note: Only perform the above procedure when you are sure that

all the correct settings are programmed into the controller. Sav-

ing the settings overwrites any previously saved collection of

settings. Be sure to document all the controller settings.

Programming the Home Page

Watlow’s patented user-defined menu system im-

proves operational efficiency. The user-defined Home

Page provides you with a shortcut to monitor or

change the parameter values that you use most of-

ten.

You can create your own Home Page with as

many as 20 of the active parameters. When a param-

eter normally located in the Setup Page or Opera-

tions Page is placed in the Home Page, it is acces-

sible through both. If you change a parameter in the

Home Page, it is automatically changed in its origi-

nal page. If you change a parameter in its original

page it is automatically changed in the Home Page.

The default parameters will automatically appear

in the Home Page.

Change the list of parameters in the Home Page

from the Custom Menu [CUSt] (Factory Page).

Tuning the PID Parameters

Autotuning

When an autotune is performed on the EZ-ZONE®

PM, the set point is used to calculate the tuning set

point.

For example, if the active set point is 200° and

Autotune Set Point [A;tSP] (Operations Page, Loop

Menu) is set to 90 percent, the autotune function

utilizes 180° for tuning. This is also how autotun-

ing works in previous Watlow Winona controllers. In

addition, changing the active set point in previous

controllers causes the autotune function to restart;

where with the EZ-ZONE® PM changing the set

point after an autotune has been started has no af-

fect.

A new feature in EZ-ZONE® PM products will al-

low set point changes while the control is autotun-

ing, this includes while running a profile or ramping.

When the auto tune is initially started it will use

the current set point and will disregard all set point

changes until the tuning process is complete. Once

complete, the controller will then use the new set

point.

This is why it is a good idea to enter the active set

point before initiating an autotune.

Autotuning calculates the optimum heating and/

or cooling PID parameter settings based on the sys-

tem's response. Autotuning can be enabled whether

or not TUNE-TUNE+™ is enabled. The PID settings

generated by the autotune will be used until the au-

totune feature is rerun, the PID values are manually

adjusted or TRU-TUNE+® is enabled.

To initiate an autotune, set Autotune Request

[`AUt] (Operations Page, Loop Menu) to [`YES].

You should not autotune while a profile is running. If

the autotune cannot be completed in 60 minutes, the

autotune will time-out and the original settings will

take effect.

The lower display will flash between [tUnE] and

the set point while the autotuning is underway. The

temperature must cross the Autotune Set Point five

times to complete the autotuning process. Once com-

plete, the controller controls at the normal set point,

using the new parameters.

Select a set point for the tune with Autotune Set

Point. The Autotune Set Point is expressed as a per-

cent of the Closed Loop Set Point.

If you need to adjust the tuning procedure's ag-

gressiveness, use Autotune Aggressiveness [T;Agr]

(Setup Page, Loop Menu). Select under damped [Un-

dr] to bring the process value to the set point quick-

ly. Select over damped [ouer] to bring the process

value to the set point with minimal overshoot. Select

critical damped [Crit] to balance a rapid response

with minimal overshoot.

Manual Tuning

In some applications, the autotune process may not

provide PID parameters for the process characteris-

tics you desire. If that is the case, you may want to

tune the controller manually.

1. Apply power to the controller and establish a set

point typically used in your process.

2. Go to the Operations Page, Loop Menu, and set

Heat Proportional Band [`h;Pb] and/or Cool Pro-

portional Band [`C;Pb] to 5. Set Time Integral

[``ti] to 0. Set Time Derivative [``td] to 0.

3. When the system stabilizes, watch the process

value. If it fluctuates, increase the Heat Propor-

tional Band or Cool Proportional Band value in 3

to 5° increments until it stabilizes, allowing time

for the system to settle between adjustments.

4. When the process has stabilized, watch Heat

Power [`h;Pr] or Cool Power [`C;Pr] (Operations

Page, Monitor Menu). It should be stable ±2%. At

this point, the process temperature should also

be stable, but it will have stabilized before reach-

ing the set point. The difference between the set

point and actual process value can be eliminated

with Integral.

5. Start with an Integral value of 6,000 and allow

10 minutes for the process temperature to reach

the set point. If it has not, reduce the setting by

half and wait another 10 minutes. Continue re-

ducing the setting by half every 10 minutes until

the process value equals the set point. If the pro-

cess becomes unstable, the Integral value is too

small. Increase the value until the process stabi-

lizes.

6. Increase Derivative to 0.1. Then increase the set

point by 11° to 17°C. Monitor the system’s ap-

proach to the set point. If the process value over-

shoots the set point, increase Derivative to 0.2.

Increase the set point by 11° to 17°C and watch

the approach to the new set point. If you increase

Derivative too much, the approach to the set

point will be very sluggish. Repeat as necessary

until the system rises to the new set point with-

out overshoot or sluggishness.

For additional information about autotune and PID

control, see related features in this chapter.

Autotuning with TRU-TUNE+®

The TRU-TUNE+® adaptive algorithm will optimize

the controller's PID values to improve control of dy-

namic processes. TRU-TUNE+® monitors the process

variable and adjusts the control parameters auto-

matically to keep your process at set point during set

point and load changes. When the controller is in the

adaptive control mode, it determines the appropriate

output signal and, over time, adjusts control param-

eters to optimize responsiveness and stability. The

TRU-TUNE+® feature does not function for on-off

control.

The preferred and quickest method for tuning a

loop is to establish initial control settings and contin-

ue with the adaptive mode to fine tune the settings.

Setting a controller's control mode to tune starts

this two-step tuning process. (See Autotuning in this

chapter.) This predictive tune determines initial,

rough settings for the PID parameters. Then the loop

automatically switches to the adaptive mode which

fine tunes the PID parameters.

Once the process variable has been at set point for

a suitable period (about 30 minutes for a fast process

to roughly two hours for a slower process) and if no

further tuning of the PID parameters is desired or

needed, TRU-TUNE+™ may be turned off. However,

keeping the controller in the adaptive mode allows it

to automatically adjust to load changes and compen-

sate for differing control characteristics at various

set points for processes that are not entirely linear.

Once the PID parameters have been set by the

TRU-TUNE+™ adaptive algorithm, the process, if

shut down for any reason, can be restarted in the

adaptive control mode.

Turn TRU-TUNE+™ on or off with TRU-TUNE+™

Enable [t;tUn] (Setup Page, Loop Menu).

Use TRU-TUNE+™ Band [t;bnd] (Setup Page,

Loop Menu) to set the range above and below the

set point in which adaptive tuning will be active.

Adjust this parameter only in the unlikely event

that the controller is unable to stabilize at the set

point with TRU-TUNE+™ Band set to auto (0). This

may occur with very fast processes. In that case, set

TRU-TUNE+™ Band to a large value, such as 100.

Use TRU-TUNE+™ Gain [`t;gn] (Setup Page,

Loop Menu) to adjust the responsiveness of the adap-

tive tuning calculations. Six settings range from 1,

with the most aggressive response and most poten-

tial overshoot (highest gain), to 6, with the least ag-

gressive response and least potential for overshoot

(lowest gain). The default setting, 3, is recommended

for loops with thermocouple feedback and moderate

response and overshoot potential.

Before Tuning

Before autotuning, the controller hardware must be

installed correctly, and these basic configuration pa-

rameters must be set:

• Sensor Type [`SEn] (Setup Page, Analog Input

Menu), and scaling, if required;

• Function [``Fn] (Setup Page, Output Menu) and

scaling, if required.

How to Autotune a Loop

1. Enter the desired set point or one that is in the

middle of the expected range of set points that

you want to tune for.

2. Enable TRU-TUNE+®.

Watlow EZ-ZONE® PM Integrated Controller • 56 • Chapter 9 Features

3. Initiate an autotune. (See Autotuning in this

chapter.)

When autotuning is complete, the PID parameters

should provide good control. As long as the loop is in

the adaptive control mode, TRU-TUNE+® continu-

ously tunes to provide the best possible PID control

for the process.

WARNING! During autotuning, the controller sets the output

to 100 percent and attempts to drive the process variable

Inputs

Calibration Offset

Calibration offset allows a device to compensate for

an inaccurate sensor, lead resistance or other factors

that affect the input value. A positive offset increases

the input value, and a negative offset decreases the

input value.

The input offset value can be viewed or changed

with Calibration Offset [`i;CA] (Operations Page,

Analog Input Menu).

Calibration

To calibrate an analog input, you will need to provide

two electrical signals or resistance loads near the ex-

tremes of the range that the application is likely to

utilize. See recommended values below:

Sensor Type Low Source High Source

thermocouple 0.000 mV 50.000 mV

millivolts 0.000 mV 50.000 mV

volts 0.000V 10.000V

milliamps 0.000 mA 20.000 mA

100 Ω RTD 50.00 Ω 350.00 Ω

1,000 Ω RTD 500.00 Ω 3,500.00 Ω

Follow these steps for a thermocouple or pro-

cess input:

1. Apply the low source signal to the input you are

calibrating. Measure the signal to ensure it is ac-

curate.

2. Read the value of Electrical Measurement [`Mu]

(Factory Page, Calibration Menu) for that input.

3. Calculate the offset value by subtracting this val-

ue from the low source signal.

4. Set Electrical Input Offset [ELi;o] (Factory Page,

Calibration Menu) for this input to the offset val-

ue.

5. Check the Electrical Measurement to see whether

it now matches the signal. If it doesn’t match, ad-

just Electrical Offset again.

6. Apply the high source signal to the input. Mea-

sure the signal to ensure it is accurate.

7. Read the value of Electrical Measurement for

that input.

8. Calculate the gain value by dividing the low

source signal by this value.

9. Set Electrical Slope [ELi;S] (Factory Page, Cali-

bration Menu) for this input to the calculated

gain value.

10. Check the Electrical Measurement to see wheth-

er it now matches the signal. If it doesn’t match,

adjust Electrical Slope again.

Set Electrical Offset to 0 and Electrical Slope to 1 to

restore factory calibration.

Follow these steps for an RTD input:

1. Measure the low source resistance to ensure it

is accurate. Connect the low source resistance to

the input you are calibrating.

2. Read the value of Electrical Measurement [`Mu]

(Factory Page, Calibration Menu) for that input.

3. Calculate the offset value by subtracting this val-

ue from the low source resistance.

4. Set Electrical Input Offset [ELi;o] (Factory Page,

Calibration Menu) for this input to the offset val-

ue.

5. Check the Electrical Measurement to see whether

it now matches the resistance. If it doesn’t match,

adjust Electrical Offset again.

6. Measure the high source resistance to ensure it

is accurate. Connect the high source resistance to

the input.

7. Read the value of Electrical Measurement for

that input.

8. Calculate the gain value by dividing the low

source signal by this value.

9. Set Electrical Slope [ELi;S] (Factory Page, Cali-

bration Menu) for this input to the calculated

gain value.

10. Check the Electrical Measurement to see wheth-

er it now matches the signal. If it doesn’t match,

adjust Electrical Slope again.

Filter Time Constant

Filtering smoothes an input signal by applying a

first-order filter time constant to the signal. Filter-

ing the displayed value makes it easier to monitor.

Filtering the signal may improve the performance of

PID control in a noisy or very dynamic system.

Adjust the filter time interval with Filter Time

[`FiL] (Setup Page, Analog Input Menu).

Example: With a filter value of 0.5 seconds, if the

process input value instantly changes from 0 to 100

and remained at 100, the display will indicate 100 after

five time constants of the filter value or 2.5 seconds.

Sensor Backup

Sensor backup maintains closed-loop control after an

input failure by switching control to input 2.

The sensor backup feature is only available in an

EZ-ZONE® PM Integrated limit or remote set point

controller.

Turn sensor backup on or off with Sensor Backup

Enable [`S;bA] (Setup Page, Analog Input 1).

Set Point Low Limit and High Limit

The controller constrains the set point to a value be-

tween a set point low limit and a set point high limit.

Set the set point limits with Low Set Point

[`L;SP] and High Set Point [`h;SP] (Setup Page,

Loop Menu).

There are two sets of set point low and high lim-

its: one for a closed-loop set point, another for an

open-loop set point.

Scale High and Scale Low

When an analog input is selected as process voltage

or process current input, you must choose the value

of voltage or current to be the low and high ends. For

example, when using a 4 to 20 mA input, the scale

low value would be 4.00 mA and the scale high value

would be 20.00 mA. Commonly used scale ranges are:

0 to 20 mA, 4 to 20 mA, 0 to 5V, 1 to 5V and 0 to 10V.

You can create a scale range representing other

units for special applications. You can reverse scales

from high values to low values for analog input sig-

nals that have a reversed action. For example, if 50

psi causes a 4 mA signal and 10 psi causes a 20 mA

signal.

Scale low and high low values do not have to match

the bounds of the measurement range. These along

with range low and high provide for process scaling

and can include values not measureable by the control-

ler. Regardless of scaling values, the measured value

will be constrained by the electrical measurements of

the hardware.

Select the low and high values with Scale Low

[`S;Lo] and Scale High [`S;hi]. Select the displayed

range with Range Low [`r;Lo] and Range High

[`r;hi] (Setup Page, Analog Input Menu).

Range High and Range Low

With a process input, you must choose a value to rep-

resent the low and high ends of the current or voltage

range. Choosing these values allows the controller’s

display to be scaled into the actual working units of

measurement. For example, the analog input from a

humidity transmitter could represent 0 to 100 per-

cent relative humidity as a process signal of 4 to 20

mA. Low scale would be set to 0 to represent 4 mA

and high scale set to 100 to represent 20 mA. The in-

dication on the display would then represent percent

humidity and range from 0 to 100 percent with an

input of 4 to 20 mA.

Select the low and high values with Range Low

[`r;Lo] and Range High [`r;hi] (Setup Page, Analog

Input Menu).

Receiving a Remote Set Point

The remote set point feature allows the controller

to use a thermocouple, RTD, 1 k potentiometer or

process signal at input 2 to establish the set point,

Watlow EZ-ZONE® PM Integrated Controller • 58 • Chapter 9 Features

which allows its set point to be manipulated by an

external source. A common application would use one

ramping controller with a set-point retransmit out-

put to ramp multiple controllers using the remote set

point. Or you could use an analog output from a PLC

to send set point values to an EZ-ZONE® PM.

The controller must have two process inputs to

use the remote set point feature.

You may select between local and remote set

points at the front panel, with an event input, from a

remote computer using the communications feature

or from an external switch using an event input.

Make sure all input and output impedances are

compatible.

Switch to the remote set point with Remote En-

able [`r;En] (Operations Page, Loop Menu). Select

whether the remote set point controls an open- or

closed-loop set point with Remote Set Point Type

[`r;ty].

Assign the function of switching to a remote set

point to a digital input with Digital Input Function

[``Fn] (Setup Page, Digital Input Menu).

Assign the function of switching to a remote set

point to the EZ Key with Digital Input Function

[``Fn] (Setup Page, Function Key Menu).

Outputs

Duplex

Certain systems require that a single process output

control both heating and cooling outputs. An EZ-

ZONE® PM controller with a process output can func-

tion as two separate outputs.

With a 4 to 20mA output the heating output will

operate from 12 to 20mA (0 to +100 percent) and the

cooling output will operate from 12 to 4mA (0 to -100

percent).

In some cases this type of output is required by

the device that the EZ-ZONE® PM controls, such as

a three-way valve that opens one way with a 12 to

20mA signal and opens the other way with a 4 to

12mA signal. This feature reduces the overall system

cost by using a single output to act as two outputs.

Outputs 1 and 3 can be ordered as process out-

puts. Select duplex [dUPL] as the Output Function

[``Fn] (Setup Page, Output Menu). Set the output to

volts [uoLt] or milliamps [`MA] with Output Type

[`o;ty]. Set the range of the process output with

Scale Low [`S;Lo] and Scale High [`S;hi].

No-arc Relay

A no-arc relay provides a significant improvement in

the life of the output relay over conventional relays.

Conventional mechanical relays have an expected

life of 100,000 cycles at the rated full-load current.

The shorter life for conventional relays is due to the

fact that when contacts open while current is flowing

metal degradation occurs. This action produces un-

avoidable electrical arcing causing metal to transfer

from one contact to the other. The arcing conditions

continue on each subsequent contact opening until

over time the resistance through the contacts in-

creases causing the contacts to increase in tempera-

ture. Eventually, the contacts will weld together and

the relay remains in the on state.

The Watlow no-arc relay is a hybrid relay. It uses

a mechanical relay for the current load and a triac

(solid-state switch) to carry the turn-on and turn-off

currents. No-arc relays extend the life of the relay

more than two million cycles at the rated full-load

current.

Although a no-arc relay has significant life advan-

tages, a few precautions must be followed for accept-

able usage:

Do not use:

• hybrid relays for limit contactors. A limit or

safety device must provide a positive mechanical

break on all hot legs simultaneously;

• dc loads with hybrid relays. The triacs used for

arc suppression will turn off only with ac line

voltage;

• hybrid switches to drive any inductive loads, such

as relay coils, transformers or solenoids;

• cycle times less than five seconds on hybrid

switches;

• on loads that exceed 264V ac through relay;

• on loads that exceed 15 amperes load;

• on loads less than 100 mA;

• no-arc relays in series with other no-arc relays.

Retransmitting a Process Value or Set Point

The retransmit feature allows a process output to

provide an analog signal that represents the set

point or process value. The signal may serve as a

remote set point for another controller or as an in-

put for a chart recorder documenting system perfor-

mance over time.

In choosing the type of retransmit signal the op-

erator must take into account the input impedance

of the device to be retransmitted to and the required

signal type, either voltage or milliamps.

Typically applications might use the retransmit

option to record one of the variables with a chart re-

corder or to generate a set point for other controls in

a multi-zone application.

Outputs 1 and 3 can be ordered as process out-

puts. Select retransmit [rMt] as the Output Func-

tion [``Fn] (Setup Page, Output Menu). Set the out-

put to volts [uoLt] or milliamps [`MA] with Output

Type [`o;ty]. Select the signal to retransmit with

Retransmit Source [`r;Sr].

value, the retransmit output will be at its Scale Low

value. When the retransmit source is at the Range

High value, the retransmit output will be at its Scale

Cool Output Curve

A nonlinear output curve may improve performance

when the response of the output device is nonlinear.

If a cool output uses one of the nonlinear curves a

PID calculation yields a lower actual output level

than a linear output would provide.

These output curves are used in plastics extruder

applications: curve 1 for oil-cooled extruders and

curve 2 for water-cooled extruders.

Control Methods

Output Configuration

Each controller output can be configured as a heat

output, a cool output, an alarm output or deactivat-

ed. No dependency limitations have been placed on

the available combinations. The outputs can be con-

figured in any combination. For instance, all three

could be set to cool.

Heat and cool outputs use the set point and Oper-

ations parameters to determine the output value. All

heat and cool outputs use the same set point value.

Heat and cool each have their own set of control pa-

rameters. All heat outputs use the same set of heat

control parameters and all cool outputs use the same

set of cool output parameters.

Each alarm output has its own set of configura-

tion parameters and set points, allowing independent

operation.

Auto (closed loop) and Manual (open loop) Control

The controller has two basic modes of operation, auto

mode and manual mode. Auto mode allows the con-

troller to decide whether to perform closed-loop con-

trol or to follow the settings of Input Error Failure

[FAiL] (Setup Page, Loop Menu). The manual mode

only allows open-loop control. The EZ-ZONE® PM

controller is normally used in the auto mode. The

manual mode is usually only used for specialty appli-

cations or for troubleshooting.

Manual mode is open-loop control that allows the

user to directly set the power level to the controller’s

output load. No adjustments of the output power level

occur based on temperature or set point in this mode.

In auto mode, the controller monitors the input to

determine if closed-loop control is possible. The con-

troller checks to make certain a functioning sensor is

providing a valid input signal. If a valid input signal

is present, the controller will perform closed-loop con-

trol. Closed-loop control uses a process sensor to de-

termine the difference between the process value and

the set point. Then the controller applies power to a

control output load to reduce that difference.

If a valid input signal is not present, the control-

ler will indicate an input error message in the upper

display and [Attn] in the lower display and respond

to the failure according to the setting of Input Error

Failure [FAiL]. You can configure the controller to

perform a “bumpless” transfer [bPLS], switch power

to output a preset fixed level [MAn], or turn the out-

put power off.

Bumpless transfer will allow the controller to

transfer to the manual mode using the last power

value calculated in the auto mode if the process had

stabilized at a ±5 percent output power level for the

time interval of Time Integral (Operations Page,

Loop) prior to sensor failure, and that power level is

less than 75 percent.

Input Error Latching [`i;Er] (Setup Page, Ana-

log Input Menu) determines the controller’s response

once a valid input signal returns to the controller.

If latching is on, then the controller will continue to

indicate an input error until the error is cleared. To

clear a latched alarm, press the Advance Key ‰ then

the Up Key ¿.

If latching is off, the controller will automatically

clear the input error and return to reading the tem-

perature. If the controller was in the auto mode when

the input error occurred, it will resume closed-loop

control. If the controller was in manual mode when

the error occurred, the controller will remain in

open-loop control.

The Manual Control Indicator Light % is on when

the controller is operating in manual mode.

You can easily switch between modes if the Con-

trol Mode [`C;M] parameter is selected to appear in

the Home Page.

To transfer to manual mode from auto mode,

press the Advance Key ‰ until [`C;M] appears in

the lower display. The upper display will display

[AUto] for auto mode. Use the Up ¿ or Down ¯ keys

to select [Man]. The manual set point value will be

recalled from the last manual operation.

To transfer to auto mode from manual mode,

press the Advance Key ‰ until [`C;M] appears in

keys to select [AUto]. The automatic set point value

will be recalled from the last automatic operation.

Changes take effect after three seconds or imme-

diately upon pressing either the Advance Key ‰ or

the Infinity Key ˆ.

On-Off Control

On-off control switches the output either full on or

full off, depending on the input, set point and hys-

teresis values. The hysteresis value indicates the

amount the process value must deviate from the set

point to turn on the output. Increasing the value de-

creases the number of times the output will cycle.

Decreasing hysteresis improves controllability. With

hysteresis set to 0, the process value would stay clos-

er to the set point, but the output would switch on

and off more frequently, and may result in the output

“ chattering.”

On-off control can be selected with Heat Algo-

rithm [`h;Ag] or Cool Algorithm [`C;Ag] (Setup Page,

Loop Menu).

On-off hysteresis can be set with Heat Hysteresis

[`h;hY] or Cool Hysteresis [`C;hY] (Operations Page,

Loop Menu).

Note: Input Error Failure Mode [faIl] does not function in on-

off control mode. The output goes off.

The cooling action switches off when the process

Proportional Control

Some processes need to maintain a temperature or

process value closer to the set point than on-off con-

trol can provide. Proportional control provides closer

control by adjusting the output when the temperature

or process value is within a proportional band. When

the value is in the band, the controller adjusts the

output based on how close the process value is to the

set point.

The closer the process value is to the set point, the

lower the output power. This is similar to backing

off on the gas pedal of a car as you approach a stop

sign. It keeps the temperature or process value from

swinging as widely as it would with simple on-off

control. However, when the system settles down, the

temperature or process value tends to “droop” short

of the set point.

With proportional control the output power level

equals (set point minus process value) divided by the

proportional band value.

Watlow EZ-ZONE® PM Integrated Controller • 61 • Chapter 9 Features

In an application with one output assigned to

heating and another assigned to cooling, each will

have a separate proportional parameter. The heating

parameter takes effect when the process temperature

is lower than the set point, and the cooling param-

eter takes effect when the process temperature is

higher than the set point.

portional Band [`h;Pb] or Cool Proportional Band

Proportional plus Integral (PI) Control

The droop caused by proportional control can be cor-

rected by adding integral (reset) control. When the

system settles down, the integral value is tuned to

bring the temperature or process value closer to the

set point. Integral determines the speed of the cor-

rection, but this may increase the overshoot at start-

up or when the set point is changed. Too much inte-

gral action will make the system unstable. Integral

is cleared when the process value is outside of the

proportional band.

Adjust the integral with Time Integral [``ti]

(Operations Page, Loop Menu).

Proportional plus Integral plus Derivative (PID)

Control

Use derivative (rate) control to minimize the over-

shoot in a PI-controlled system. Derivative (rate) ad-

justs the output based on the rate of change in the

temperature or process value. Too much derivative

(rate) will make the system sluggish.

Derivative action is active only when the process

value is within twice the proportional value from the

set point.

In a PID application the dead bands above and below

bring the process temperature to the set point.

systems from fighting each other.

Variable Time Base

Variable time base is the preferred method for con-

trolling a resistive load, providing a very short time

base for longer heater life. Unlike phase-angle firing,

variable-time-base switching does not limit the cur-

rent and voltage applied to the heater.

With variable time base outputs, the PID algo-

rithm calculates an output between 0 and 100%, but

the output is distributed in groupings of three ac

line cycles. For each group of three ac line cycles, the

controller decides whether the power should be on or

off. There is no fixed cycle time since the decision is

made for each group of cycles. When used in conjunc-

tion with a zero cross (burst fire) device, such as a

solid-state power controller, switching is done only at

the zero cross of the ac line, which helps reduce elec-

trical noise (RFI).

Variable time base should be used with solid-state

power controllers, such as a solid-state relay (SSR)

or silicon controlled rectifier (SCR) power controller.

Do not use a variable time base output for control-

ling electromechanical relays, mercury displacement

relays, inductive loads or heaters with unusual resis-

tance characteristics.

The combination of variable time base output and

a solid-state relay can inexpensively approach the ef-

fect of analog, phase-angle fired control.

cannot use variable time base, fixed time base only.

Alarms

Alarms are activated when the output level, process

value or temperature leaves a defined range. A user

can configure how and when an alarm is triggered,

what action it takes and whether it turns off auto-

matically when the alarm condition is over.

Configure alarm outputs in the Setup Page before

setting alarm set points.

Alarms do not have to be assigned to an output.

Alarms can be monitored and controlled through the

front panel or by using software.

Process and Deviation Alarms

A process alarm uses one or two absolute set points

to define an alarm condition.

A deviation alarm uses one or two set points that

are defined relative to the control set point. High

and low alarm set points are calculated by adding or

subtracting offset values from the control set point.

If the set point changes, the window defined by the

alarm set points automatically moves with it.

Select the alarm type with Type [`A;ty] (Setup

Page, Alarm Menu).

Alarm Set Points

The alarm high set point defines the process value

or temperature that will trigger a high side alarm.

It must be higher than the alarm low set point and

lower than the high limit of the sensor range.

The alarm low set point defines the temperature

that will trigger a low side alarm. It must be lower

than the alarm high set point and higher than the

low limit of the sensor range.

Alarm Hysteresis

An alarm state is triggered when the process value

reaches the alarm high or alarm low set point. Alarm

hysteresis defines how far the process must return

into the normal operating range before the alarm can

be cleared.

Alarm hysteresis is a zone inside each alarm set

point. This zone is defined by adding the hysteresis

value to the alarm low set point or subtracting the

hysteresis value from the alarm high set point.

function.

If the EZ-ZONE® PM has an output that is func-

tioning as a deviation alarm, the alarm is blocked

when the set point is changed, until the process value

re-enters the normal operating range.

Turn alarm blocking on or off with Blocking

[`A;bL] (Setup Page, Alarm Menu).

Current Sensing

Open heater circuit detection

Current Error [`C;Er] (Operations Page, Current

Menu) detects an open load circuit if no current is

flowing through the current transformer when the

output is active and the load is supposed to be on.

Shorted heater circuit detection

Current Error detects a shorted load circuit if cur-

rent is flowing through the current transformer

when the output is inactive and the load is supposed

to be off.

Set the current detect set points with High Set

Point [`C;hi] and Low Set Point [`C;Lo] (Operations

Page, Current Menu).

Programming the EZ Key

You can program the EZ Key either in the Setup

Menu or with configuration software, such as EZ-

ZONE® Configurator, using a personal computer.

The following examples show how to program the

EZ Key to start and stop a profile.

Using keys and display:

1. To go to the Setup Page from the Home Page,

press both the Up ¿ and Down ¯ keys for six sec-

onds. [``Ai] will appear in the upper display and

[`Set] will appear in the lower display.

2. Press the Up Key ¿ until [`Fun] appears in the

upper display and [`SEt] will appear in the lower

display.

3. Press the Advance Key ‰ until Digital Input Level

[`leu] appears in the lower display. Use an ar-

row key to specify the state of the key (high or low)

when the controller is powered up. Functions will

toggle with each press of the EZ Key, such as Pro-

file Start/Stop.

4. Press the Advance Key ‰. The lower display will

show Digital Function [``Fn]. Press the Up ¿ or

Down ¯ key to scroll through the functions that

can be assigned to the EZ Key

When Profile Start/Stop [P;StS] appears in the

upper display and [``Fn] appears in the lower

display, press the Advance Key ‰ once to select

that function and move to the Function Instance

[``Fi] parameter.

5. Press the Up ¿ or Down ¯ key to scroll to the

profile that you want the EZ Key to control.

6. The instance tells the controller which of the

numbered functions should be acted upon. For

profiles, there are 4 instances. Press the Infinity

Key ˆ once to return to the submenu, twice to

return to the main menu or three times to return

to the Home Page.

Using the software with Standard Bus:

1. Make the necessary physical connections between

the personal computer and the EZ-ZONE® PM.

Set Protocol (Setup Page, Communications Menu)

to Standard Bus. Run the software and allow it

to connect to the controller by directing it or al-

lowing it to find the appropriate communications

port.

2. After the software connects to the controller, look

on the left side of your screen under the Param-

eters Menus for Function Key under Setup. Click

on the plus sign to reveal the Function Key 1

submenu.

3. Click on Function Key 1, then select a Digital In-

put Function and a Function Instance.

If you want to start and stop a profile with the EZ

Key, select Profile Start/Stop and the number of the

profile that you want the EZ Key to control.

Using Lockout to Secure Settings

If unintentional changes to parameter settings might

raise safety concerns or lead to downtime, your can

use the lockout feature to make them more secure.

Each of the menus in the Factory Page and each

of the pages, except the Factory Page, has a security

level assigned to it. You can change the read and

write access to these menus and pages by using the

parameters in the Lockout Menu (Factory Page).

Lockout Menu

There are four parameters in the Lockout Menu (Fac-

tory Page):

Lock Operations Page [LoC;o] sets the security level

for the Operations Page. (default: 2)

Lock Profiling Page [LoC;P] sets the security level

for the Profiling Page. (default: 3)

Read Lockout Security [rLoC] determines which

pages can be accessed. The user can access the

selected level and all lower levels. (default: 5)

Set Lockout Security [SLoC] determines which pa-

rameters within accessible pages can be written

to. The user can write to the selected level and

all lower levels. (default: 5)

Home Page: 1

Operations Page: 1

or 3

Setup Page: 4

Profiling Page: 1

or 3

Security Levels

Bars indicate page and menu access by security level.

The following examples show how the Lockout

Menu parameters may be used in applications:

1. You can lock out access to the Operations Page

but allow an operator access to the Profile Menu,

by changing the default Profile Page and Opera-

tions Page security levels. Change Lock Opera-

tions Page [LoC;o] to 3 and Lock Profiling Page

[LoC;P] to 2. If Set Lockout Security [SLoC] is

set to 2 or higher and the Read Lockout Security

[rLoC] is set to 2, the Profiling Page and Home

Pages can be accessed, and all writable parame-

ters can be written to. Pages with security levels

greater than 2 will be locked out (unaccessible).

2 If Set Lockout Security [SLoC] is set to 0 and

Read Lockout Security [rLoC] is set to 5, all

pages will be accessible, however, changes will

not be allowed on any pages or menus, with one

exception: Set Lockout Security [SLoC] can be

changed to a higher level.

3. The operator wants to read all the menus and not

allow any parameters to be changed.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 5 and Set Lockout

Security [SLoC] to 0.

4. The operator wants to read and write to the

Home Page and Profiling Page, and lock all other

pages and menus.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 2 and Set Lockout

Security [SLoC] to 2.

In the Factory Page, Lockout Menu, set Lock

Operations Page [LoC;O] to 3 and Lock Profiling

Page [LoC;P] to 2.

5. The operator wants to read the Operations

Page, Setup Page, Profiling Page, Diagnostics

Menu, Lock Menu, Calibration Menu and Cus-

tom Menus. The operator also wants to read and

write to the Home Page.

In the Factory Page, Lockout Menu, set Read

Lockout Security [rLoC] to 1 and Set Lockout

Security [SLoC] to 5.

In the Factory Page, Lockout Menu, set Lock

Operations Page [LoC;O] to 2 and Lock Profiling

Page [LoC;P] to 3.

Note: Avoid continuous writes within loops. Excessive writes to

EEPROM will cause premature EEPROM failure. The EEPROM is

rated for 1,000,000 writes.
