2 Yes The control unit automatically clears the alarm if the fault condition is no
longer detected.
[No] The control unit does not automatically reset the alarm when the fault condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
The charge alternator monitoring issues an alarm if the voltage
measured at the auxiliary excitation input D+ (terminal 52) falls
below a fix limit.
The fix limit depends on the power supply voltage. If a power
supply voltage exceeding 16 V is detected, the unit assumes a
24 V system and uses a limit of 20 V. If a power supply voltage
below 16 V is detected, the unit assumes a 12 V system and uses
a limit of 9 V.
