input to the This 0 to 15 V input signal reports an arc
master unit, 0 detected by the slaves. The master then
to 15 V handles the arc in the same manner it does
as a stand-alone unit. This signal is low
(0 V+/- 0.5 V) when an arc is being
reported by the slave. It is 15 V at all other
times.

to 5 V or 0 to It is an analog representation of the
10 V current at the slave1 output. It is a fully
differential signal; pin 24 (SL1 FBK-) is
the return. It is scaled according to the
output power of the unit: 0 to 10 V for a
30 kW unit and 0 to 5 V for a 15 kW unit.
input to the This 0 to 15 V input signal from the slaves
master unit, 0 reports a fault in slave2. A slave fault can
to 15 V be bus high, bus low, overtemp, interlock,
or failure of the main contactor to close. A
high signal (15 V), indicates a slave fault;
a low signal (0 V+/- 0.5 V) indicates
normal operation.
return for pin This is the return signal for pin 25.
