The MAIN LED lights green. Wait for approximately 20 to 30 seconds until
the MAG.DRIVE has been initiated.
If the pump has the optional TMS (including e.g. the red heater band) the
heater will be activated. The setpoint temperature will be reached within 30
- 60 minutes depending on cooling water temperature and flow.
In case of corresponding connection the backing pump will be activated

of the system take care that neither ambient air nor cleaning agents enter
the pump.
After a failure has occured and has been removed, acknowledge the failu-
