digital convertor) in the Sensor Monitoring
Module; the ADC must be replaced.
WARNING 5411
MB TEMP
The temperature of the LCMB pump is too
high. Check the pumping system inlet
pressure; has the pumping system been
operating with inlet pressure > 5 mbar
(5 x 10
2
Pa) for 1 hour or more. If the
maximum inlet pressure has not been
exceeded, or if the pumping system has not
been operated at the maximum inlet pressure
for longer than the specified time, the
cooling-circuit of the pump maybe blocked.
WARNING 5413 Check that the LCMB pump temperature
sensor is fitted and is correctly connected. If
the sensor is correctly fitted and connected, it
may have failed. Check the operation of the
sensor and replace it if it has failed.
WARNING 5511
DP MOTOR TEMP
MOTOR WATER LOW
