To locate the fault, check in RUN mode which BI/O lines has
been activated (see page 57). Check the wirings of the BI/O
lines.
NOTE!
The fault codes 11 and 12 can also be the result of an interfer-
ence light detected by an arc sensor. If a sensor remains acti-
vated for more than 7 seconds, the slave unit to which it is
connected will be disconnected from the system. At the same
time a fault alarm is given. Once the interference light disap-
pears the slave unit restores its normal function and the fault
alarm is reset.
NOTE!
Fault code 12 can also be a result of a too low overcurrent set-
ting in the alarming master unit or any master unit connected
to the alarming unit via the Ib> BIO line.
Fault code 13 indicates that an error has been detected in the
system communication. The fault message does not include any
slave unit address number.
Check the modular cables and their connectors.
NOTE!
In case the fault codes keep appearing after cutting the auxil-
iary supply of the arc protection system, and the mentioned
measures do not solve the problem, please, contact the
manufacturer or his nearest representative.
7.3.4. VAM 12 CD TEST/ERROR indication
The TEST/ERROR indicator of VAM 12 CD will remail lit
during an internal fault of the slave unit. The master unit will
show a fault code 11, see page 61 for description. The
TEST/ERROR indicator will also lit up during arc sensor
activation. The indicator will remain lit only the time that the
sensor is detecting an arc.
Due to continuous self testing of the system configuration the
TEST/ERROR indicator is lit up for couple of seconds once in
every 2 or 3 minutes, no actions need to be taken.
