WARNING 3911
EXHAUST PRESSURE
EXHAUST BLOCKED
SERVICE PUMP
The pressure in the exhaust pipeline is too high.
There may be process debris or condensation in the
exhaust pipeline, or a valve in the pipeline may be
shut. You may have too many pumping systems
connected to the exhaust pipeline.
WARNING 3913 The exhaust pressure transducer is not fitted, or is
disconnected or has failed. Check and rectify as
necessary.
WARNING 4009
SS PURGE LOW
ADJUST REGULATOR
INCREASE PRESS.
The shaft-seals purge pressure is too low. Check that
the nitrogen supply is as specified in Section 2 and
that you have correctly adjusted the pressure: refer
to Section 5.6.
WARNING 4010
SS PURGE LOW
PRESSURE LOW
ADJUST REGULATOR
Refer to the recommended actions for error number
4009 in this table.
WARNING 4011
SS PURGE HIGH
PRESSURE HIGH
CHECK GAS MODULE
The shaft-seals purge pressure is too high. Check that
you have correctly adjusted the pressure: refer to
Section 5.6. If you cannot correctly adjust the
pressure, the regulator may be faulty.
WARNING 4012
SS PURGE HIGH
PRESSURE HIGH
CHECK GAS MODULE
Refer to the recommended actions for error number
4011 in this table.
WARNING 4013 The shaft-seals pressure transducer is not fitted, or is
disconnected or has failed. Check and rectify as
necessary.
WARNING 5113 There is a fault in the ADC (analogue-to-digital
convertor) in the Control SMA; the Control SMA must
be replaced.
WARNING 5409 SEE MANUAL The operating temperature of the HMB pump is too
low. The cooling water solenoid valve may be stuck in
the on position.
WARNING 5411
MB TEMP
SEE MANUAL The operating temperature of the HMB pump is too
high. The cooling water solenoid valve may be stuck
in the off position, or the cooling-circuit of the pump
may be blocked.
WARNING 5413 Check that the HMB 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
CHECK WATER
The temperature of the FDP pump-motor is too high.
Check the cooling-water connections in the iF system
and check that the cooling-water supply is on and is
as specified in Section 2. If the connections and
supply are correct, the cooling-circuit of the pump
maybe blocked.
WARNING 5513 The HMB pump-motor surface temperature sensor is
not fitted, or is disconnected or has failed.
