A short time after the internal self-supervision system has detected a permanent relay fault the red IRF indicator
is lit and the output relay of the self-supervision system operates. Further, in most fault situations, an auto-
diagnostic fault code is shown on the display. This fault code consists of a red figure 1 and a green code number
which indicates the fault type. When a fault code appears on the display, the code number should be recorded
and given to the authorized repair shop when overhaul is ordered. In the table below some fault codes that
might appear on the display of the SPCJ 4D24 module are listed:
Fault code Type of error in module
4 Faulty trip relay path or missing output relay card
30 Faulty program memory (ROM)
50 Faulty work memory (RAM)
51 Parameter memory (EEPROM) block 1 faulty
52 Parameter memory (EEPROM) block 2 faulty
53 Parameter memory (EEPROM) block 1 and block 2 faulty
54 Parameter memory (EEPROM) block 1 and block 2 faulty with different checksums
56 Parameter memory (EEPROM) key faulty. Format by writing a "2" to variable V167
195 Too low a value in reference channel with multiplier 1
131 Too low a value in reference channel with multiplier 5
67 Too low a value in reference channel with multiplier 25
203 Too high a value in reference channel with multiplier 1
139 Too high a value in reference channel with multiplier 5
75 Too high a value in reference channel with multiplier 25
252 Faulty filter on Io channel
253 No interruptions from the A/D-converter
