3.2 DESCRIPTION OF CONTROLS—US/CAN MODELS ONLY

-14-

Revision 4/F3535 ©Moffat Ltd, June 2004

3.3 EXPLANATION OF CONTROL

SYSTEM

The E311 Turbofan convection oven features

multi-function operator controls for which a

correct understanding of their operation is

required before carrying out any service or fault

repair work. The control device functions are

explained as follows:

A power switch on the control panel isolates all

power to the controls of the oven. With the power

switch Off all functions of the oven are

inoperable.

NOTE: The supply voltage is fed directly to the

input side of the power relay whenever the

electrical supply is on.

With the power switch On (illuminated) power is

directly supplied to the 60 minute bake timer,

steam (water injection) switch, door microswitch,

light switch, and the hold switch circuit. (On units

manufacture prior to serial number 232053 power

is also supplied directly to the temperature control

circuit). Accordingly the oven circulation fan will

operate when the door is closed, and with door

open the oven light will come on and the circula-

tion fan will shut down, as these are controlled via

the door microswitch. The control panel light

switch will turn the oven light on when the door is

closed. On units from S/N 260862 the switch is

latching and will activate the light while latched in

the down position. On units prior to S/N 260861

the switch is momentary and will need to be held

in to activate the light.

The 60 minute timer is a mechanical timer and

can therefore be operated with the oven’s power

switch On or Off. However, only with the oven’s

power switch On will the switch contacts of the 60

minute timer turn on the time-up buzzer and

illuminate the time-up indicator on the control

panel. The buzzer and time-up indicator provide

indication that the time setting has run down to

zero and at this point will remain On continuously

until the 60 minute timer has been manually set

back to the Off (vertical) position. The 60 minute

timer does not control any other part of the oven’s

operating system as this timer is independent of

the temperature control and heating system.

US/Canada only: The steam (water injection)

switch on the control panel can be operated

whenever the power switch is On. The switch is

momentary and when depressed, will operate the

electric solenoid valve at the rear of the oven and

inject water into the water trough at the bottom of

the left hand side rack in the oven. Releasing the

steam button will close the solenoid valve. This

feature is used to instantaneously add moisture

into the oven cavity, or to introduce a reservoir of

water in the water trough to maintain humidity in

the oven chamber and minimise product’s

moisture loss during cooking.

For units manufactured from serial number

232054, power to the temperature control circuit

and elements is supplied via a power relay

located near the terminal block at the rear of the

unit. Although the power relay has two poles with

changeover contacts, only the normally closed

contact on one pole is used - the other is

redundant. When the power switch on the control

panel is switched on the power relay is energised

and the normally open contact is closed,

providing power to the temperature control circuit.

The temperature control of this oven is with a

capillary type thermostat which can be set to a

required cooking temperature, or set to the Grill/

Broil position to provide top browning or grilling/

broiling in the oven.

The thermostat switch has a separate switch

body assembled onto the front from the shaft

assembly and when the thermostat is set to a

cooking temperature, one set of contacts is

closed to switch power from the oven thermostat

to the bottom heating element in the oven. The

second switch contact of this switch assembly

remains open in this setting and isolates power

from the top element inner coil. The top element

outer coil is directly switched on from the oven

thermostat. Accordingly only the top outer

element and the bottom element are used when a

cooking temperature is selected. The control

panel indicator light above the thermostat knob

cycles On and Off with the thermostat to indicate

when the elements are on and the oven is

heating.

When the thermostat control is set to the Grill

position the first switch contact opens and the

second switch contact closes. This arrangement

allows power to be provided to the top element

inner coil when the thermostat is On, and isolates

power from going to the bottom heating element.

The top element outer coil which is directly fed

from the oven thermostat switch is therefore On

in conjunction with the top element inner coil

when the thermostat is set to the Grill position.

As both the top inner and outer element coils are

thermostatically controlled, the elements will cycle

On/Off with the door closed as the thermostat

setting in the Grill position is 300°C (600°F). If the

Grill position is selected with the door open, the

elements will remain On continuously and the

-15-

Revision 4/F3535 ©Moffat Ltd, June 2004

circulation fan will be turned Off. The control

panel Grill indicator will illuminate when the

thermostat is set to the Grill position and will cycle

On and Off with the main heating indicator light.

The E311 Turbofan convection oven features a

Roast-and-Hold system which can be used to

automatically set the oven to a fixed holding

temperature at the end of a timed cooking period.

From serial number 232054: When the Roast-

and-Hold switch is turned On the switch will

illuminate and turn on a relay found on the inside

of the control panel. (This relay has two poles

with changeover contacts, but only one pole is

used). When this relay is switched On the

normally closed contact opens, isolating the

normal power supply to the oven thermostat and

the normally open contact closes supplying power

to the 3 hour roast timer.

To serial number 232053: When the Roast-and-

Hold switch is turned On the switch will illuminate

and turn on a mini-contactor found on the inside

of the control panel. When this relay is switched

On a normally closed switch pole on the contactor

is open and the normal power supply to the oven

thermostat is isolated. A second normally open

switch pole is closed and this provides power to

the 3 hour roast timer.

If the roast timer is in the Hold (vertical) position

the timer switch contacts will be in their normally

closed position and supply power directly to the

Hold thermostat located behind the control panel.

The Hold thermostat is factory set to 75°C (167°

F) and will directly supply power to the bottom

heating element as required to maintain its preset

temperature.

If the main thermostat is turned On, power will

also be supplied to the top outer element coil

through the first switch contact of the thermostat

front switch assembly. In this case the

thermostat heating light will also cycle On/Off as

the Hold thermostat maintains temperature.

In the Roast-and Hold mode the 3 hour timer can

be set to a selected roasting time. During this

time period the normally open switch contacts of

the timer are closed. The timer has two change

over switches and in this position one is used to

supply power to its timing motor and the other is

used to switch power directly to the main oven

thermostat. During the 3 hour timer run-down

period the oven temperature will be controlled by

the main oven thermostat to the set temperature

and operate as previously described.

When the 3 hour timer has run down and reached

the Hold position the two switch contacts change

over to their normally closed position which

isolates power from the timer motor and the oven

thermostat. It also switches power back to the

oven hold thermostat. At this point the

temperature control is now maintained by the

hold thermostat as previously described. To

cancel the hold circuit the Roast-and-Hold switch

is turned Off. This turns off the contactor which

removes power from the 3 hour timer and closes

the contactor pole on the contactor that feeds the

main oven thermostat.

The factory preset hold thermostat can be

adjusted as required to change the holding

temperature if necessary. Refer Service section

for this procedure.

The following Troubleshooting Guide should be

used to identify any incorrect oven operation. On

correct identification of the operating fault the

Troubleshooting Guide will make reference to the

corrective action required, or refer to the Fault

Diagnosis section and/or Service section to assist

in correction of the fault.

6.1 FAULT DIAGNOSIS

Incorrect electrical supply

Check that the voltage across phase and

neutral (L1 and L2) terminals of terminal block is

the voltage as stated on the unit’s electrical rating

plate.

If incorrect, check electrical connection of supply

wiring and / or check electrical supply.

6.1.1 OVEN DOES NOT OPERATE / START

Power switch faulty

Check if power switch latches. If the switch does

not latch, then switch is faulty—replace.

With switch latched, check voltage across

terminal one to terminal three or four. If there is

no voltage, check for fault in wiring.

Check voltage across terminal two to terminal

three or four. If there is no voltage, then switch is

faulty—replace.

NOTE: When power switch is latched, it should

illuminate if operating correctly.

6.1.2 FAN DOESN’T OPERATE

Microswitch out of adjustment

Open oven door and manually depress door

microswitch actuator at top right of oven. If this

activates the fan, then the microswitch actuator

arm at rear of oven requires adjustment.

Microswitch faulty

Check voltage across microswitch terminals to

neutral.

With the door closed there should be power to the

com terminal and the n.o. terminal.

With the door open there should be power to the

com terminal and the n.c. terminal.

If not, microswitch is faulty—replace.

Fan motor faulty

Check the supply voltage across motor terminals.

6.1.3 OVEN LIGHT NOT ILLUMINATING—

DOOR OPEN

terminals at rear of oven. If the voltage is correct,

replace the bulb (if faulty). If the bulb is OK,

check lamp housing. Replace if faulty.

If there is no voltage, open oven door and

manually depress door microswitch actuator at

top right of oven. If this activates the fan, then

the microswitch actuator arm at rear of oven

requires adjustment.

Check voltage across micro-switch terminals to

neutral.

With the door closed there should be power to the

com terminal and the n.o. terminal.

With the door open there should be power to the

com terminal and the n.c. terminal.

If not, microswitch is faulty—replace.
