FAULT: Battery, loop unit zz-aa
Press "" to see the technical address.
FAULT: Battery, techn. address xxx
zz-aa = Zone-Address. xxx = COM loop address.
This is valid for an external power supply (e.g. 3366) connected on the
COM loop.
Batteries (2 x 12 V) are missing or not correctly connected.
Battery fuse is blown.
FAULT: Cables mixed on COM-loop
The two wires L (SA) and C (SB) have been mixed (alternated). Check
so that the wire connections are correct (according to drawing 128-21).
FAULT: Charging, external power supply
The fault is to be found in the external power supply equipment. A
fault output is connected to a programmable input in the EBL128
system. Check the input as well.
FAULT: Charging, techn addr xxx
This is valid for an external power supply (e.g. 3366) connected on the
COM loop.
The battery charging function is not working all right. The charger
board (3367) may have to be replaced.
FAULT: Checksum system program
A fault in the EBL128 S/W. This is very serious. Call for service
personnel / engineer immediately.
FAULT: Cut-off SCI nn <-> SCI nn
This fault is indicating a cut-off (break) on the loop or that the COM
loop voltage is too low at the end of the loop (i.e. < 12 V DC).
SCI nn <->SCI nn describes between which Short Circuit
Isolators (SCI:s) the cut-off is located.
nn = A, B, 0, 1, 2, 3, 4, 5, 6 or up to 63. A & B is the built-in isolator
in the EBL128 A-direction and B-direction respectively, i.e. if no SCI
is used the information will always be: SCI A <-> SCI B.
If one SCI (no. 0) is used, the information will be:
