The inverter on an iH1000 system has
experienced a transient power supply problem,
or there is a recoverable fault.
WARNING 17701 SEE MANUAL
The HCMB pump stator temperature is
> 165
o
C, and the HCMB pump speed has been
reduced to 1200 r.min
-1
. The warning
condition will be removed and the HCMB
pump speed will increase to 6000 r.min
-1
again
when the pump stator temperature has fallen
to 150
o
C.

ALARM 512
The pump-motor has tripped out because the
motor windings are too hot: either the
cooling-system has failed or the motor
overloaded. Either of these faults should have
been identified before shut-down, so either
there are two separate faults (for example,
cooling-water supply failure and thermocouple
circuit failure) or the thermistor circuit has
failed: contact your supplier or Edwards.
