CB fail
BO/BI
ON pulse is shortened/interrupted
and replaced by UV and OFF pulse
In this moment, the
reason for closing the CB
is activated again (e.g.
Remote Start/Stop is
activated).
Minimum 1s delay after
UV coil is switched on
is needed before CB
can be closed
OFF and UV pulses are
always activated for the full
time (2s). Manual control (=
CB button) is deactivated
during opening pulse.
Further behavior of UV output depends on the system status.
In case of transition to cooling stays off, if the Cb was opened
manually and the engine keeps running, it activates again
after timeout elapses.
NOTE:
This is not valid for BTB. BTB fail
is not detected in this case.
BTB can be opened externally
and this state is always confirmed
by the controller and no alarm is
issued.
The reaction of the controller is
shown in next graphs.
Alarm detection is immediate
