TLON network (TLON Manager).
NOTE! Programmed control units have to be connected / running.
FAULT: CU xx has wrong information
Control units have data stored, which is not the same in all control
units. The control units have to be synchronised via menu H8/S7.
NOTE! Programmed control units have to be connected / running.
FAULT: CU xx too high current consumption
The control unit current consumption is over 2.5A, and because of
this, the battery charging is turned off. Normally this fault only
appears when starting up / expanding a system.
FAULT: Cut-off COM-loop x, CU xx
This is indicating a single break on the loop. Communication has to be
performed in both directions, to find all units.
May also be shown after a short circuit on the loop when short circuit
isolators are used (= communication in both directions).
(A double break will give the message: FAULT: No reply .....).
NOTE! Communication in both directions lasts for about ten minutes,
when a new attempt to communicate in one direction is performed. If
the break remains, a new ten minutes period starts, and so on. If the
fault is acknowledged and the break is corrected during a ten minutes
period, it will not disappear from the list until the end of the ten
minutes period.

FAULT:Cut-off loop x, CU xx,ASF 1<->CU
FAULT:Cut-off loop x, CU xx,ASF 0<->CU
This is indicating a single break on the COM loop "x" when one, two,
three or four short circuit isolators 2370, ASF, are connected on
the loop. Communication has to be performed in both directions, to
find all units. The break is to be found in the specified segment (e.g.
