4.3 Manual shut-down
The pump can be shut down using either the MicroTIM, the PDT or the front panel local control membrane. Note that
only the item in control can stop the pump (refer to Section 1.4).
Front panel local control membrane operation:
Press and hold the stop button (Figure 4, item 3) until the running LED (Figure 4, item 8) flashes. The running LED
will then turn off when the pump has shut down.
MicroTIM operation:
Use the control equipment to reset the pump start/stop signal to the interface connector. The Running LED (Figure 4,
item 8) will then go off, and the pump running status output signal will open.
PDT operation:
Selecting either ’normal’ or ’fast’ shut down will shut the pump down immediately.
If the pump is not going to be required for some time, switch off the electrical supply and the cooling water supply.
If shutting the system down and don't isolate it from the electrical supply, do not disconnect the
Pump Display Terminal or release control from the Pump Display Terminal or front panel. If so, the
system could be started by another Module.
Do not remove the inlet connections until the pump has been allowed to stop rotating and the
power has been isolated. The pump can take up to three minutes to completely stop.
