load current is 500 mA.
l When minor alarms are generated, JK2 is short-
circuited.
l When critical alarms are generated, JK1 is short-
circuited.
l Users can define alarm levels through the BAM
program.
The maximum voltage is 5.6 VDC and the maximum
current is 20 mA.
l Pin 1 is for the signal cable.
l Pin 2 is reserved.
Pin 1 and pin 2 are connected to pole C and pole E of
the optical coupler.
The optical coupling parameter Vce max is 40 VDC and
Ic max is 80 mA. Avoid setting the parameters to the
maximum values.
l Pin 1 is for the signal cable FU1+ and is connected
to the negative pole of the battery.
l Pin 2 is reserved for the FU1- signal.
l Pin 1 is for the +24 V power supply.
