4.1.1 MCM MicroTIM operation

If the dry pumping system is to be operated by the user's control equipment by the
MCM MicroTIM, ensure that no other devices have control of the dry pumping system. If
another device has the control, it must 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 on the rear panel

▪ 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 while 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

on and warming up. Once the pump has warmed up and is ready for the process,
the running LED will remain illuminated continuously and the Green mode LED will
