3) Fault in connections or cables to external temperature sensor.
4) Fault in temperature sensor.
5) Internal circuit fault. Send for qualified service personnel.
FAULT TYPE 02
Alarm condition: Internal reference voltage deviates from the permitted margin (0.5 %).
Fault causes: 1) The alarm delay period set too low. Short-term variations may occur
without being regarded as faults. Select delay period of at least a few
seconds.
2) Recalibration necessary. Carried out automatically in connection with
calibration of the battery voltage measurement, see section 5.12.4.
3) Extremely high or low ambient temperature.
4) Internal circuit fault. Send for qualified service personnel.
FAULT TYPE 03
Alarm condition: The monitoring unit's I/O board reports a fault.
Fault causes: 1) Internal circuit fault. Send for qualified service personnel.
COMMUNICATION FAULT
Function: Monitors serial communications with rectifier, I/O unit and any other units.
Alarm condition: A sent message gets no approved response despite ten resend attempts.
Interlocking: -
Fault causes: 1) Fault in the connections and cables.
2) Internal circuit faults in either sending or receiving unit.
3) The Number of rectifiers parameter is incorrectly set.
Other: Together with the fault message, a number is shown that specifies which unit is
not responding, as follows:
0 General for all the rectifier units.
1-8 Specific to individual rectifier unit. The number specifies the unit in
question.
10 EEPROM, i.e. the circuit that stores parameters (long-term memory).
11 I/O unit
12 Satellite panel
13 I/O unit 2
