24V 12A FAIL- (Yellow) Normally OFF. When illuminated, indicates
that the 24VDC non-power limited output
has a trouble condition or the PSC-12 has
disconnected the 24VDC output due to
current overload or short circuit.
24V 4A FAIL - (Yellow) Normally OFF. When illuminated, indi-
cates that the 24VDC power limited
output has a trouble condition or the
PSC-12 has disconnected the 24VDC
power output due to current overload or
short circuit.
Three rotary dial switches located directly below the LEDs are used to set
the HNET network address of the PSC-12.
The terminal blocks of the PSC-12 are defined as follows (refer to Figure 2):
TB1 Currently NOT USED.
TB2 Relay Outputs. Four user-programmable relays that are set to
NOT USED by default. These outputs are rated 2A @ 30VDC/
120VAC (.6PF). (Refer to Figure 3 for wiring the relays.)
These relays are controlled by the NCC WAN only. NCC WAN
version 6.01.007 or higher is required. The relays can be config-
ured in the NCC WAN as Global Alarm, Global Trouble or
General Output.
A relay configured as Global Alarm changes the respective PSC
relay state to off normal when there is any alarm on the NCC.
When all alarms are cleared on the NCC, the relay state will
restore to normal.
A relay configured as Global Trouble changes the respective
PSC relay state to off normal when there is any trouble on the
NCC. When all troubles are cleared on the NCC, the relay state
will restore to normal.
A relay configured as General Output will change state only
through a manual command from the NCC, using either the
Device Output Control or using the Disable/Enable (DIS/ENA)
and Energize/DeEnergize (ENE/DEE) manual commands.
