The shaft-seals purge pressure is too low.<br />
Check that the nitrogen supply is as specified<br />
in Section 2 and that you have correctly<br />
adjusted the pressure: refer to Section 5.7.<br />
Refer to the recommended actions for error<br />
number 4009 in this table.<br />
The shaft-seals purge pressure is too high.<br />
Check that you have correctly adjusted the<br />
pressure: refer to Section 5.7. If you cannot<br />
correctly adjust the pressure, the regulator may<br />
be faulty.<br />
Refer to the recommended actions for error<br />
number 4011 in this table.<br />
WARNING 4013 The shaft-seals pressure transducer is not<br />
fitted, or is disconnected or has failed. Check<br />
and rectify as necessary.<br />
WARNING 5113 There is a fault in the ADC (analogue-to-digital<br />
convertor) in the Control SMA; the Control<br />
SMA must be replaced.<br />
WARNING 5411<br />
MB TEMP<br />
The temperature of the HCMB pump is too<br />
high. Check the pumping system inlet<br />
pressure; has the pumping system been<br />
operating with inlet pressure > 5 mbar<br />
(5 x 10 2 Pa) for 1 hour or more. If the<br />
maximum inlet pressure has not been<br />
exceeded, or if the pumping system has not<br />
been operated at the maximum inlet pressure<br />
for longer than the specified time, the<br />
cooling-circuit of the pump maybe blocked.<br />
WARNING 5413 Check that the HCMB pump temperature<br />
sensor is fitted and is correctly connected. If<br />
the sensor is correctly fitted and connected, it<br />
may have failed. Check the operation of the<br />
sensor and replace it if it has failed.<br />
WARNING 5511<br />
DP MOTOR TEMP<br />
MOTOR WATER LOW<br />
CHECK WATER<br />
Table 6-1 - Warning messages (continued)<br />
The temperature of the HCDP pump- motor is<br />
too high. Check the cooling-water connections<br />
in the <strong>iH</strong> system and check that the<br />
cooling-water supply is on and is as specified<br />
in Section 2. If the connections and supply are<br />
correct, the cooling-circuit of the pump maybe<br />
blocked.<br />
