Fault codes
34
Shortly 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
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 value in reference channel with multiplier 1
131 Too low value in reference channel with multiplier 5
67 Too low value in reference channel with multiplier 25
203 Too high value in reference channel with multiplier 1
139 Too high value in reference channel with multiplier 5
75 Too high value in reference channel with multiplier 25
252 Faulty filter on I
253 No interruptions from the A/D-converter
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 4D29 module are listed:
