FAULT: Output x, techn addr xxx
This is valid for COM loop output unit outputs.
If the output is programmed for sounders (type Alarm devices), it is
also indicated by LED "Fault / Disablements Alarm devices" (L13)
blinking.
If the output is programmed for fire brigade tx (type Routing
equipment), it is also indicated by LED "Fault / Disablements Fire
brigade tx" (L15) blinking.
Calibration not performed via menu H5/A3.
Short-circuit / break on the connected cable / equipment.
Connected equipment might be "stolen".
End-of-line capacitor(s) missing or not correct value (see
drawing 128-28).
NOTE! The calibrated value has to be in the range 470 nF – 5 x
470 nF (2350 nF).
FAULT: Read/write site data (SSW)
Some external influence has caused a fault in the SSW (the data that is
changed during operation, i.e. sensor values, access codes, etc.). This
is very serious. Call for service personnel / engineer immediately.
FAULT: Restart, code xx addr yyyyyyyyyyy
C.i.e. (EBL128) restart has occurred. See also page 74.
xx=00:
Power up Restart. (Power supply connected)
xx=01:
Watchdog Reset.
xx=02:
Accidental jump to reset vector.
xx=03:
Restart after SSD / Software / text file download
xx=04-19: Unexpected interrupt.
xx=20:
S/W monitoring fault
NOTE!
xx=00 and 03 are normal. Only acknowledge the "fault".
xx=01, 02 or 04-20 appearing often: call for service personnel /
engineer.
yy...y = memory address (before restart). Write down the
address and inform the service personnel/engineer.
FAULT: Several faults on COM-loop
Breaks (cut-offs) / short-circuits in more than one segment on the
COM loop. Normally this fault is generated in conjunction with some
cut-off faults / short-circuit faults. In that case, first correct one fault
and the next fault will be presented.
