    Scope and defi ni tions This manual provides installation, operation and maintenance instructions for the BOC Edwards EXDC80 and EXDC160 Turbomolecular Pump Drive Modules (abbreviated to EXDC in the remainder of this manual). You must use the EXDC as specified in this manual. If you do not, the protection provided by the EXDC may be impaired, or you may damage the EXDC, or cause injury to people.

  • Page 6: De Scrip Tion

    De scrip tion The EXDC controls the electrical supply for a BOC Edwards EXT70, EXT70H, EXT250, EXT255H, EXT351 or EXT501 turbomolecular pump. The EXDC has no manual controls and can only be operated through the logic interface. To operate the EXT pump, you must therefore connect the EXDC to your own control equipment and electrical supply (see Figure 3).

    Elec tri cal con nec tions 3.4.1 In tro duc tion Use a suitable connector mating half (not supplied) to connect the electrical supplies and your control equipment to the connector on the logic interface cable (Figure 1, item 3). When you make the electrical connections to the EXDC described in the following sections, refer to Table 1 for full details of the logic interface connections and to Figure 3 for a schematic diagram of the connections.

    3. Connect your control equipment to the TMP normal status output (pin 2) and to pins 5 or 6 of your logic interface mating half. You can use the output to control other devices in your pumping system. The output can drive a low power relay of up to 24 V coil rating.

  • Page 15: Op Era Tion

    OP ERA TION WARNING Do not disconnect the EXDC from the EXT pump when the pump is operating. At full speed, the EXT pump motor generates 48 V RMS which is accessible at the pump to Controller electrical connection, and there may be a risk of injury by electric shock.

  • Page 16: Nor Mal Shut Down

    Temperature sensors in the EXDC and the EXT pump are monitored by the EXDC. If the EXDC detects that the pump temperature or its own temperature is too high, the power supplied to the pump-motor is reduced; the pump may not therefore be able to maintain full rotational speed if it is too hot.

  • Page 17: Elec Tri Cal Sup Ply Fail Ure

    The EXDC has an electronic EXT pump speed control system. This control system prevents operation of the EXT pump at over 100% of its normal full rotational speed (as operation above this speed reduces bearing operational life). If required, you can monitor the speed analogue output and configure your control equipment to switch off the EXT pump if its speed exceeds 100% of full rotational speed.
