Faults and alarms
List of faults and alarms
yy = 3:
The data checksum in p7774 is not correct.
yy = 4:
No data available to load.
Remedy: - Perform the remedy according to the results of the troubleshooting.
- If necessary, start the action again.
F03001 NVRAM checksum incorrect
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: A checksum error occurred when evaluating the non-volatile data (NVRAM) on the Control Unit.
The NVRAM data affected was deleted.
Remedy: Carry out a POWER ON (power off/on) for all components.
F03505 (N, A) CU: Analog input wire breakage
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: The wire-break monitoring for an analog input has responded.
The input current of the analog input has undershot the threshold value parameterized in p0761[0...3].
p0756[0]: analog input 0 (only CU240D-2)
p0756[1]: analog input 1 (only CU240D-2)
Fault value (r0949, interpret decimal):
yxxx dec
y = analog input (0 = analog input 0 (AI 0), 1 = analog input 1 (AI 1))
xxx = component number (p0151)
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.
The input current measured by the analog input can be read in r0752[x].
A03510 (F, N) CU: Calibration data not plausible
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: - power down/power up the power supply for the Control Unit.
If it reoccurs, 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
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?
