Designation Possible cause Remedy
85 to

Frequency converter collective error
97 Internal volume temperature error
101 Overload warning
The pump speed has dropped under
the normal operation threshold
Forevacuum pressure too
high.
Gas flow too high
Check the ultimate pressure of the backing
pump and install a bigger backing pump if
req.
Seal leak, check process
103 Supply voltage warning
Intermediate circuit voltage too low or
maximum time for generator operation
was exceeded.
DC supply voltage below 24V
or 48 V
Mains voltage has failed
Check the voltage at the power supply and if
required set up correctly
Remedy the cause for the mains power failure
106 Overload error
The pump speed has dropped under
the minimum speed
Forevacuum pressure too
high.
Gas flow too high
Check the ultimate pressure of the backing
pump and install a bigger backing pump if
req.
Seal leak, check process
111 The minimum permissible motor tempe-
rature is not attained.
Ambient temperature too low
Pump cooling too high
Ensure min. ambient tempera ture of 5 °C
Reduce water coo ing
116 The speed of the pump has dropped
below the normal operation threshold
and has stayed there for a longer period
of time.
Forevacuum pressure too
high.
Gas flow too high
Check the ultimate pressure of the backing
pump and install a bigger backing pump if
req.
Seal leak, check process
117 Motor current error (start-up error),
Motor current below nominal current,
switchover from open loop controlled to
closed loop controlled operation was
not successful
Cable fault
Faulty connector
Contact Leybold Service
126 Bearing temperature sensor error, top Defective component, short-
circuit or broken cable
Contact Leybold Service
128 Motor temperature sensor error Defective component, short-
circuit or broken cable
Contact Leybold Service
143 Overspeed error
225 Bearing break-in function active Disable bearing break-in function and restart
the pump
226 Temperature derating active. One of the
temperature warning values was excee-
ded and the maximum permissible
motor current was reduced
227 to
238
Frequency converter collective error DIVAC 0.8 / 3.0 (24 V DC) is
not turning although the func-
tion code was set up correct-
ly, fuse F4 has blown.
Check fuse F4 (8A slow-blow) and replace as
required.
The location of the fuses is indicated in fig. 3.9
and 3.10.
Reset error, try to restart. If this is not possible
inform Leybold Service or send in the pump.
240 EEPROM error (CRC) inconsistent data
in the EEPROM
Reset error, try to restart. If this is not possible
inform Leybold Service or send in the pump.
