Figure 10 - Rear panel connections

3.3.1 Connecting the electrical supply

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 you do 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 suppl y 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 your 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: Do not remove the bottom nut from the earth stud.

D397-12-880 Issue J

CAUTION

3.3.3 Connecting a turbo pump

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 backi ng pump via the lo gic interfac e. For details o f this, refer t o

Section 3.3.7.3.

The 200 W TIC can also drive a suitable backing pump from it’s second rear panel pump conn ector. 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.

Installation

Note: To control an XDD1 24 V backing pump, the pump must be configured for ‘analogue speed control’. Please

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 11).

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 marke d ‘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 powe r supply common to prevent

earth loops inadvertently occurring.

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 your 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.

D397-12-880 Issue J

CAUTION

WARNING

Installation

3.3.7.2 Using control inputs

Control inputs provide a means of controlling the operation of the TIC and the associ ated vacuum system from external sources.

Turbo Stand-by: to full speed, disconnect ‘Turbo Stand-by’ from 0 V. Note only pumps that have stand-by speed capability will respond to this input.

Turbo Enable: 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 abl e 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.

To cause the turbo pump to run at stand-by speed, link ‘Turbo Stand-by’ to 0 V. To return the pump

The turbo enable input can be used to control the operation of the turbo pump . If turbo enable is open,

’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:

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.

The vent valve output on the logic interface will not be maintained in the event of a power failure. If venting of your 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.

3.3.7.4 Using status outputs

Status outputs provide a means for external systems to react based upon the current state of the TIC.

Installation

Analogue output: 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 your system and ‘Analogue Output Common’ to the negative side.

Relay setpoint: output can be configured in software to activate at pump speed. Refer to Section 4.15 of the main manual 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 rela y 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: 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’ (ne gative) and ‘Power Supply

Positive’ (positive).

The analogue output provides a 0 V to 10 V signal that can be configured to represent system

The setpoint outputs can be used to interface to external logic or can be used to drive relays. Each

Turbo normal speed can be used to interface to external logic or can be used to drive a relay.

3.3.8 Connecting the serial interface

The TIC has two serial communications protocols built in, RS232 and RS485. RS232 is the simple st 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 th e rear pan el. The interface uses tw o li nes fo r da ta tra nsfers a nd 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.

Figure 11 - IBM PC RS232 interface - 9-way

D397-12-880 Issue J

CAUTION

Installation

Figure 12 - IBM PC RS232 interface - 25 way

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.

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 RS 485 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 Ω terminating resistors at each end of the link to improve communications reliability.

settings (relay setpoints, units, etc.).

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 and will supply power back to the TIC. This power will be used to maintain operation of the vent valve, and if enough power is available the TIC will maintain operation.

The power returned to the TIC is not made available to 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.
