Cause: The 󹪞ow rate is too low, and has fallen below the speci󹪝ed fault threshold.
Remedy
: - Check the coolant 󹪞ow rate.
- Chec
k 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 speci󹪝ed alarm t
hr
eshold.
If t
he coolant t
em
perature increases up to the speci󹪝ed 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 speci󹪝ed fault t
hreshold.
Fault value (r0949, int
erpret 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 value channels ar
e displayed in the following diagnostic parameters.
Remedy: Evaluate the diagnostic parameters.
If the actual value channel is incorr
ect, 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 the tem
perature of the heat sink increases by 5 K.
