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)

p0756[0...2] = 3 (4 ... 20 mA 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) 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: - power down/power up 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.

A03520 (F, N) Temperature sensor fault

Message class: External measured value / signal state outside the permissible range (16)

Reaction: NONE

Acknowledge: NONE

Cause: When evaluating the temperature sensor, an error occurred.

It is expected that an LG-Ni1000 temperature sensor (p0756[2...3] = 6) or PT1000 p0756[2...3] = 7 is connected via

the analog input.

Alarm value (r2124, interpret decimal):

33: Analog input 2 (AI2) wire breakage or sensor not connected.

34: Analog input 2 (AI2) measured resistance too low (short circuit).

49: Analog input 3 (AI3) wire breakage or sensor not connected.

50: Analog input 3 (AI3) measured resistance too low (short circuit).
