Warning Message
on Display
Motor Temp.
Temperature sensor inside
the motor reads a higher
temperature value than the
warning threshold (130 °C).
Bearing Temp.
Temperature sensor inside
the pump reads a higher tem-
perature value than the war-
ning threshold (98 °C).
Converter Temp.
Temperature sensor inside of
the converter reads a higher
temperature value than the
warning threshold (70 °C).
Cooling Temp.
Temperature sensor at coo-
ling water block reads a hig-
her temperature value than
the warning threshold
(50 °C).
Operation Cycles
The registered number of
start and standby cycles
exceeds the permissible num-
ber (normal warning thres-
hold). So as not to constantly
mask this warning by others,
it is only displayed during run-
up (up to approximately 150
Hz) and during standby ope-
ration.
The registered number of
start and standby cycles
exceeds the permissible num-
ber (warning threshold 2 and
3). The warning is now
displayed constantly.

Measures
Take the actual motor temperature reading
from the display; see Section 3.10.1.
Reduce gas load. If the warning persists con-
tact Leybold service.
Contact Leybold service.
Apply cooling water according to specifica-
tions. Check cooling water tubes for deposits.
See also Section 2.5.
Allow pump to cool down between the
cycles.
Allow converter to cool down between the
cycles.
Refer to Section 2.7 for the correct mounting
of the converter in a rack; max. ambient tem-
perature 45 °C.
Apply cooling water according to specifica-
tions. Check cooling water tubes for deposits.
See also Section 2.5.
Make a service date.
Make a service date.
Possible Cause
Motor temperature exceeds the warning
threshold e.g. due to a high gas load.
Drive failure or internal converter failure.
Cooling water flow too low or cooling
water temperature too high.
Frequent acceleration and deceleration of
the pump.
Frequent acceleration and deceleration of
the pump.
No sufficient air circulation.
Cooling water flow too low or cooling
water temperature too high.
Intensive utilisation of the standby mode
or a high number of starting processes.
This section will only be active provided
the menu item "Operating Hours/Cycles”
remains set to "Warning”.
The operating time of the pump attains
the pre-set warning threshold.
