4 Faults and alarms
4.2 List of faults and alarms
Note:
For the following analog input type, the wire breakage monitoring is active:
p0756[0...1] = 1 (2 ... 10 V with monitoring)
Remedy: - check the connection to the signal source for interruptions.
- check the magnitude of the injected current - it is possible that the infed signal is too low.
Note:
The input current measured by the analog input can be read in r0752[x].
A03510 (F, N) Calibration data not plausible
Message class: Hardware/software error (1)
Reaction: NONE
Acknowledge: NONE
Cause: During booting, the calibration data for the analog inputs is read and checked with respect to plausibility.
At least one calibration data point was determined to be invalid.
Remedy: - switch off/switch on the power supply for the Control Unit.
Note:
If it reoccurs, then replace the module.
In principle, operation could continue.
The analog channel involved possibly does not achieve the specified accuracy.
A05000 (N) Power unit: Overtemperature heat sink AC inverter
Message class: Power electronics faulted (5)
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for overtemperature at the inverter heat sink has been reached. The response is set using
p0290.
If the temperature of the heat sink increases by an additional 5 K, then fault F30004 is initiated.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the cooling failed?
A05001 (N) Power unit: Overtemperature depletion layer chip
Message class: Power electronics faulted (5)
Reaction: NONE
Acknowledge: NONE
Cause: Alarm threshold for overtemperature of the power semiconductor in the AC converter has been reached.
Note:
- the response is set using p0290.
- if the depletion layer temperature increases by an additional 15 K, then fault F30025 is triggered.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- have the load conditions and the load duty cycle been appropriately dimensioned?
- has the cooling failed?
- pulse frequency too high?

A05002 (N) Power unit: Air intake overtemperature
Message class: Power electronics faulted (5)
Reaction: NONE
Acknowledge: NONE
Cause: For chassis power units, the following applies:
The alarm threshold for the air intake overtemperature has been reached. For air-cooled power units, the threshold is
42 °C (hysteresis 2 K). The response is set using p0290.
If the air intake temperature increases by an additional 13 K, then fault F30035 is output.
