Operation
4.1.1 MCM MicroTIM operation
If the dry pumping system is to be operated by the user’s own control equipment by the MCM MicroTIM, ensure that
no other devices have control of the dry pumping system. If another device does have control it must first be released
before the pump can be started by the MCM MicroTIM.
 Use the control equipment to set the pump start/stop signal to the interface connector and check that the
running LEDs are illuminated.
 The MCM MicroTIM takes control. The message ‘MTIM IN CONTROL’ will be displayed on the PDT if connected.
The green Tool Control LED (Figure 3, item 9) on the rear panel will illuminate.
4.1.2 PDT operation
If the dry pumping system is to be operated using the PDT:
 Connect the PDT to the required PDT connection, front (Figure 1, item 11) or rear (Figure 3, item 5).
 Control must be taken with the PDT - press Control button. The message ‘PDT1 IN CONTROL’ will be
displayed if the front connection is used and the message 'PDT2 IN CONTROL' will be displayed if the rear
connection is used.
 Press START button (refer to Appendix A2 for more information).
 Press ENTER.
 The dry pumping system will start and the Running LED on the pump and the Pump On LED on the PDT will
flash whilst the pump is coming on and warming up. These LEDs will stop flashing and remain illuminated
continuously once the pump is on-process.
4.1.3 Front panel control operation
To operate the dry pumping system using the front panel controls (refer to Figure 1):
 Press and hold the local control button (Figure 1, item 5). The green local control LED (Figure 1, item 6) will
illuminate continuously when control is taken. The message ‘Keys in Control’ will be displayed on the PDT if
connected.
 Press and hold the start button (Figure 1, item 3) until the pump starts. The running LED (Figure 1, item 2)
and Green Mode LED (Figure 1, item 10) will both flash whilst the pump is coming on and warming up. Once
the pump has warmed up and is ready for process, the running LED will remain illuminated continuously and
the Green Mode LED will go off.
4.1.4 Start, warm-up and on-process sequences
GXS dry pumping systems are shipped with a number of pre-programmed sequences. Many of the parameters are
configurable. Parameters can be configured using a PDT, refer to Appendix A2. The PDT is available as an accessory,
refer to Section 7.3.
