7.14.5 Pump-motor supervision: Overload or blockage





The SelfCheck Assistant monitors the Varioflex pump:

1. Alarm sounds as dual-tone signal for pump-motor overload or

blockage.

2. Display of

bL0C

signals blockage.

3. The red LED

above the fault triangle

flashes.



Heater switches off on both poles,



Pump and refrigerating unit are switched off electronically.



Find the cause of the fault. Perhaps the viscosity of the heat

transfer liquid is too high or the pump is blocked.



Press the Enter key.



Also press this key if the unit has been switched off in the fault

state.

Command

Pump-motor alarm!



Pump-motor alarm is shown in the display and signifies that

unlocking is only possible on the Master control panel.

7.14.6 Pump-motor supervision: Dry running





The SelfCheck Assistant monitors the Varioflex pump:

1. Alarm sounds as dual-tone signal when the pump runs without

liquid. This can only occur when the float level measurement has
failed.

2. The display of

PuLEU

signals that the SelfCheck Assistant

has detected a pump low level.

3. The red LED

above the fault triangle

flashes.



Heater switches off on both poles,



Pump and refrigerating unit are switched off electronically.



The cause of the failure of the level measurement with the floatation sensor must be
found and rectified. Perhaps it is blocked by foreign bodies in the bath.



Press the Enter key.



Also press this key if the unit has been switched off in the fault

state.

Command

Alarm! Low level (pump)



Alarm! Low level (pump) is shown in the display and signifies

that unlocking is only possible on the Master control panel.
