Cause: The ow rate is too low, and has fallen below the specied fault thr
eshold.
Remedy: - Check the coolant ow r
ate.
- Check the thermal conductivity of the coolant.
- Check the coolant concentration.
A30086 Power unit: coolant temperature has exceeded the alarm threshold
Message class: Power electronics faulted (5)
Message value: %1
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The coolant temperature has exceeded the specied alarm t
hr
eshold.
If t
he coolant temperature increases up to the specied fault threshold, then fault F30087 is output.
Alarm value (r2124, interpret decimal):
Coolant temperature.
Remedy: Check the cooling system and the ambient conditions.
F30087 Power unit: coolant temperature has exceeded the fault threshold
Message class: Power electronics faulted (5)
Message value: %1
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: The coolant temperature has exceeded the specied fault t
hreshold.
F
ault value (r0949, interpret decimal):
Coolant temperature.
Remedy: Check the cooling system and the ambient conditions.
F30105 PU: Actual value sensing fault
Message class: Power electronics faulted (5)
Message value: -
Component: Power Unit
Response: OFF2
Acknowledgment: IMMEDIATELY
Cause: At least one incorrect actual value channel was detected on the Power Stack Adapter (PSA).
The incor
rect actual v
alue channels are displayed in the following diagnostic parameters.
Remedy: Evaluate the diagnostic parameters.
If the actual value c
hannel is incorrect, check the components and if required, replace.
A30250 Power unit: Overtemperature heat sink inverter
Message class: Power electronics faulted (5)
Message value: -
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The alarm threshold for overtemperature at the inverter heat sink has been reached.
F
ault F30004 is initiated if t
he temperature of the heat sink increases by 5 K.
