Fault codes
The event register can be read by the L-com-
mand only once. If a fault occurs e.g. in the
data transfer, the contents of the event register
read by the L-command may be re-read by
means of B-command. When required, the B-
command can be repeated. Generally, the con-
trol data communicator reads the event data and
forwards them to the output device continu-
ously. Under normal conditions the event reg-
ister of the module is empty. In the same way
the data communicator resets abnormal status
data, so this data is normally a zero.
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
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
Faulty filter on ∆I channel
252
253 No interruptions from the A/D-converter
The setting values S1...S18 are the setting val-
ues used by the protection stages. All the set-
tings can be read or written. A condition for
writing is that a remote set password has been
opened.
When settings are changed, manually or re-
motely, the relay unit checks that the variable
values are within the ranges specified in the tech-
nical data of the module. If not, the unit, will
not store the value, but keeps the previous set-
ting.
consists of a red figure 1 and a green code num-
ber which indicates the fault type. When a fault
code appears on the display, the code number
should be recorded for statistical and mainte-
nance purposes. Below are some fault codes that
might be displayed by the unit SPCJ 4D40:
