Signal Type
output from the This 0 to 15 V output signal turns the
master unit, 0 output power in each slave on and off. By
to 15V duplicating the functions of both the slave
on and slave off signals, this signal shuts
down the master/slave system quickly in
the event of a fault. An open on this line
defaults to 15 V and turns the slave off. A
low signal is 0 V +/- 0.5 V.

output from the This 0 to 15 V signal is an output from the
master unit, 0 master to the slave. It is one of three
to 15V signals that set the system output tap. It is
used with pin 1 (SL TAPA.D) and pin 2
(SL TAPC.D).
output from the This 0 to 15 V output signal from the
master unit, 0 master sets the contactor hold feature in
to 15V the slaves. A low signal (0 V+/- 0.5 V)
enables contactor hold; a high signal
(15 V) disables contactor hold.
output from the This 0 to 15 signal from the master is used
master unit, 0 with pin 3 (SLOFF.D) to turn the slave
to 15V units on and off. (See the description of
pin 3.)
input to the This 0 to 15 V signal from the slaves
master unit, 0 reports a fault in slave 1. 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 æ 0.5 V) indicates
normal operation.
return for pin 5 This is the return signal for pin 5 (SL1
FBK+.A).
input to the This input signal is used by the master to
master unit, 0 determine and control total system output.
to 10 V It is an analog representation of the
current at the slave 2 output. It is a fully
differential signal; pin 7 (SL2 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.
