Fitting the controller
WARNING
If access to the IEC connector is restricted an additional isolation device should be provided, which
will be easily accessible by an operator.

CAUTION
Rubber feet must be fitted (Figure 6, item 1) so that there are correct clearances for air circulation. If not, the
performance of the controller may be affected at high operating temperatures.
The controller can be used on a bench top or can be fitted in a rack or cabinet. Figure 6 shows the dimensions of the
TIC that are required for bench top use.
Note:

If the interlocks are not used, the logic interface adaptor must be fitted to the 25-way connector.

Connecting the electrical supply

WARNING
High voltages exist in the controller when it is operating. Ensure that the controller is earthed and
observe all appropriate safety precautions for the safe installation and handling of electrical
equipment. If not, there will be a danger of injury or death to people by electric shock.
Ensure that the electrical supply switch is set to ‘off’ and then connect the controller to the electrical supply with
an appropriate supply cable.

3.3.2

Additional earth bonding

The electrical supply cable normally provides protective earthing for electrical safety. If this is not the case, or if
additional earth bonding is required, then the earth stud on the rear of the controller (Figure 10, item 5) should be
connected to the vacuum system earth.
The earth connection of any vent valves or air coolers should also be connected to this earth stud to ensure that they
are adequately earthed.
Connect a suitably earthed cable between the two nuts fitted to the earth stud on the rear of the TIC.
Note:

Page 12

Do not remove the bottom nut from the earth stud.

Connecting a turbo pump

CAUTION
Pumps are not hot swap safe unless explicitly stated in their manual. Before connecting or disconnecting a pump
to the TIC turn the power off. Failure to do so may damage the pump.
The TIC will only identify the pump connected at power on.
A suitable turbo pump can be connected to the TIC turbo pump connector on the rear panel.
Connect the pump to the lower of the two 15 way ‘D’ connectors and tighten the locking screws to ensure the
connector cannot come loose.

3.3.4

Connecting a backing pump

Both the 100 W and 200 W TICs can control a mains backing pump via the logic interface. For details of this, refer to
Section 3.3.7.3.
The 200 W TIC can also drive a suitable backing pump from its second rear panel pump connector.
Connect the pump to the upper of the two 15 way ‘D’ connectors and tighten the locking screws to ensure the
connector cannot come loose.
Note:

To control an XDD1 24 V backing pump, the pump must be configured for ‘analogue speed control’. Refer
to the pump instruction manual for details on how to configure the pump for this operating mode.

3.3.5

Connecting a vent valve

A vent valve can be driven from either the auxiliary terminals on the rear of the TIC, or from the logic interface. For
details of using the logic interface to control a vent valve, see Section 3.3.7.3.
Note:

If a DX or nEXT pump is to be used, it is recommended that the vent valve is connected to the pump, not
the TIC Controller. If two vent valves are required, both the DX and TIC vent outputs can be used at the
same time. (Refer to Table 12).

Connect the positive lead of the vent valve to the terminal marked ‘Vent +’, connect the negative lead of the vent
valve to the terminal marked ‘Vent –’ and clamp the earth wire between the earth stud locking nuts on the rear of
the controller. Ensure the screws and the earth terminal locking nut are all firmly tightened.

3.3.6

Connecting an air cooler

An air cooler can be driven from either the auxiliary terminals on the rear of the TIC, or from the logic interface. For
details of using the logic interface to control an air cooler, refer to Section 3.3.7.3.
Connect the positive lead of the air cooler to the terminal marked ‘Fan +’, connect the negative lead of the air cooler
to the terminal marked ‘Fan –’ and clamp the earth wire between the earth stud locking nuts on the rear of the
controller. Ensure the screws and the earth terminal locking nut are all firmly tightened.

3.3.7

Connecting the logic interface

3.3.7.1

Introduction

Note:

In most applications, it will be preferable not to earth the logic interface power supply common to prevent
earth loops inadvertently occurring.

CAUTION
Do not connect voltages greater than 24 V to the logic interface.
The logic interface provides a number of signals that can be used for monitoring the status of the vacuum system and
for controlling certain aspects of its operation. These signals can be broadly divided into three groups, control inputs,
control outputs and status outputs.

3.3.7.2

Using control inputs

Control inputs provide a means of controlling the operation of the TIC and the associated vacuum system from
external sources.
Turbo Stand-by: To cause the turbo pump to run at stand-by speed, link ‘Turbo Stand-by’ to 0 V. To return the pump
to full speed, disconnect ‘Turbo Stand-by’ from 0 V. Note that only pumps having stand-by speed capability will
respond to this input.
Turbo Enable: The turbo enable input can be used to control the operation of the turbo pump. If turbo enable is open,
the turbo pump cannot be started and will stop if it is running. If turbo enable is connected to 0 V when power is
applied to the TIC, the pump is able to start when commanded to do so. If turbo enable is connected to 0 V while
the controller is operating, the turbo pump will start, as long as SYSI and the software configuration allow it to do so.
Backing Pump Enable: The backing pump enable input can be used to control the operation of the backing pump. If
backing pump enable is open, the backing pump cannot start and will stop if it is running. If backing pump enable is
connected to 0 V when power is applied to the TIC, the pump is able to start when commanded to do so. If backing
pump enable is connected to 0 V while the controller is operating, the backing pump will start, as long as ‘SYSI’ and
the software configuration allow it to do so.
SYSI: The System interlock input can be used to interlock the TIC to a system fail or control signal. When ‘SYSI’ is
open, all pumps will stop and the vent valve will be opened. The TIC will also trip into the fail condition. To clear
the system interlock and allow the pumps and gauges to start, connect ‘SYSI’ to 0 V.

WARNING
‘SYSI’ is not fail safe and should not be relied upon for safety critical applications.

3.3.7.3

Using control outputs

Control outputs provide a means for the TIC to control external resources.
Vent valve control: The vent valve output can be used to control the operation of a vent valve. The ‘Vent Valve’
signal will be driven low to energise the valve when required. Connect the positive lead of the vent valve to ‘24 V’
and the negative lead to ‘Vent Valve Control’. The vent valve earth lead must be connected to ‘Screen’ or a suitable
alternative earth point.

CAUTION
The vent valve output on the logic interface will not be maintained in the event of a power failure. If venting of
the turbo pump while it is running at high speed is undesirable, use the vent valve output from the auxiliary
terminals. This output will be maintained during a power failure.
Bakeout band control: The bakeout band control can be used to switch a relay that can apply power to the band. The
relay box has a relay built in for this purpose and provides connectors to allow power to be applied to the bakeout
band. Refer to the relay box instruction manual for further information on driving a bakeout band.
To drive a relay without a relay box, connect the coil of a suitable 24 V d.c. relay between ‘Bakeout Band Control
Output’ (negative) and ‘Power Supply Positive’ (positive).
Backing pump control: The backing pump control can be used to switch a relay that can apply power to a mains
backing pump. The relay box has a relay built in for this purpose and provides a connector that will switch the pump
on and off. Refer to the relay box instructions for further information on driving a backing pump.
To drive a relay without a relay box, connect the coil of a suitable 24 V d.c. relay between ‘Backing Pump Output’
(negative) and ‘Power Supply Positive’ (positive).
Air cooler: The air cooler output can be used to control the operation of an air cooler. The air cooler signal will be
driven low to energise the cooler when required. Connect the positive lead of the cooler to the power supply positive
and the negative lead to ‘Air Cooler Control’. The air cooler earth lead must be connected to ‘Screen’ or a suitable
alternative earth point.

Page 14

D397-12-880 Issue L

Using status outputs

Status outputs provide a means for external systems to react based upon the current state of the TIC.
Analogue output: The analogue output provides a 0 V to 10 V signal that can be configured to represent system
pressure, pump speed etc. Refer to Section 4.8 for how to configure this output.
To connect this output to an external system, connect the ‘Analogue Output Signal’ to the positive input of the
system and ‘Analogue Output Common’ to the negative side.
Relay setpoint: The setpoint outputs can be used to interface to external logic or can be used to drive relays. Each
output can be configured in software to activate at pump speed. Refer to Section 4.15 for how to configure these
outputs. Each relay can be manually controlled. Refer to Section 4.5.
The relay box has built-in relays that can switch external loads and provides a connector to interface to an external
system. Refer to the relay box instructions for further information on using the setpoint outputs.
To drive a relay without a relay box, connect the coil of a suitable 24 V d.c. relay between ‘Setpoint Output’
(negative) and ‘Power Supply Positive’ (positive).
Turbo normal speed: Turbo normal speed can be used to interface to external logic or can be used to drive a relay.
This output is normally inactive and will become active when the turbo pump has reached its defined ‘Normal’ speed.
To drive a relay, connect the coil of a suitable 24 V d.c. relay between ‘Turbo Normal Output’ (negative) and ‘Power
Supply Positive’ (positive).
Alarm: Alarm can be used to interface to external logic or can be used to drive a relay. This output is normally active
and will become inactive in the event of an alarm condition.
To drive a relay, connect the coil of a suitable 24 V d.c. relay between ‘Alarm Output’ (negative) and ‘Power Supply
Positive’ (positive).

3.3.8

Connecting the serial interface

The TIC has two serial communications protocols built in, RS232 and RS485. RS232 is the simplest interface and can
be used to allow a host PC to control the TIC. RS485 allows a host PC to control a small network of TICs.

3.3.8.1

Connecting RS232

The TIC is fitted with a 9-way ‘D’ type socket on the rear panel. The interface uses two lines for data transfers and
an additional line as a signal common. Hardware handshaking is not implemented.
If connecting to an IBM compatible PC fitted with a 9-way ‘D’ type socket then a ‘straight through’ male-female
9-way extension cable can be used to connect the TIC to the computer as shown in Figure 11. Connection to an IBM
PC fitted with a 25-way serial connector should be made as shown in Figure 12.
Use shielded cable for the interface to reduce interference problems and limit the length of the RS232 link to less
than 10 metres. For longer links, either install line drivers or use RS485.

3.3.8.2

Connecting RS485

RS485 provides the TIC with the capability to be networked with other TICs and a host PC as shown in Figure 13.

CAUTION
All of the ground connections are tied together. If differences exist in the local ground voltage, damage could
occur. If the TICs being networked are liable to experience different ground potentials, a suitable RS485 isolator
should be connected between them.
Use shielded cable for the interface to reduce interference problems and limit the length of the RS485 link to less
than 1000 metres.
Long links may require the addition of 120  terminating resistors at each end of the link to improve communications
reliability.

4.17

Electrical supply failure

If the electrical supply to the controller fails while the turbo pump is rotating at high speed, the pump begins acting
like a generator, maintaining operation of the pump electronics and supporting operation of any accessories
connected directly to the pump such as a vent valve or fan.
Additionally, certain turbo pumps can make power available to a TIC to maintain the operation of vent valves
connected to the TIC.
Where power is returned to the TIC it is not made available to the gauges, the logic interface or the air cooler. All
of these will stop operating until power is restored.
Once the turbo pump speed falls below 50%, the vent valve will open and the TIC will shut down.
Refer to the individual pump instruction manuals for availability of this feature.

Brownout/Short

5.3

Description

Either the loading on the TIC outputs exceeds a certain current level or
there was a brownout of the mains power while a turbo was spinning and
could provide some regen power. Remove the short or high load and then
accept the error; the TIC will then re-attempt to drive the output. If a
brownout occurs, wait for it to pass and then accept the error.

Cleaning the controller

If necessary, use a soft dry cloth to clean the exterior of the controller. Do not clean with harsh abrasives or liquids.
If the interior of the controller requires cleaning, Edwards recommends returning the controller to the supplier or
the nearest Edwards Service Centre.
