Error messages

In case a failure occurs, the controller will generate an error message.
Please see the list below for guidance.
MESSAGE DESCRIPTION
Run Up Time The pump has not been able to reach
a speed value >700 Hz, within the
expected value (Run Up Time, which
is configurable).
The Run Up Time value can be set
acting on the serial Win#724.
Body HW Over The temperature of the pump has
Temp exceeded the maximum allowed
value. This overtemperature
condition is deteted by an hardware
circuitry, This overtemperature
condition is deteted by an hardware
circuitry, which is independent from
the microprocessor. The maximum
allowed value is 62°C
Rotor Locked The pump rotor is not able to spin
Too High Load The supply current flowing into by
the pump is higher than the expected
value
Fault DRV8305 Mosfet bridge driver failure

Technical Information
ACTION
Check for the Run UP Time set-
up: it should be set accordingly
to the customer process. Check
for the gas load flowing inside
the pump and adjust it
accordingly.
Check that the pump rotor can
rotate freely.
Restart the pump
Check for the pump cooling
system functionality (forced air
or liquid). Check for the Gas Load
Selection setting; it has to be in
compliance with the gas type
used by the application. Wait for
the pump temperature to return
below the related threshold.
Restart the pump.
Check that the pump rotor can
rotate freely.
If not, contact Agilent to get
appropriate directions
Verify the inlet and foreline
pressure are within specified
limits. Check for the pump rotor
can spin freely.
Restart the pump
Contact Agilent to get
appropriate directions
