Controlling NACs For Sync Follower Operation Using a Control Module
B.2 Controlling NACs For Sync Follower Operation Using a Control Module
In this application, the power supply has been set to operate in slave mode and will follow the sync signal from the FACP. This applica-
tion requires Input #1 to be controlled by the FACP sync output. Input #1 may be wired to the next FL-PS or terminate in and ELR. Input
#2 (or Input #3, if available) will act as the trigger signal for the output circuits. The control module can be powered by one of the FL-PS
output circuits, configured as aux power (24VDC). See Table 3.14 on page 27 DIP switch settings.
The following notes apply to Figure B.2.
•
When the FL-PS power supply is in an inactive state (control module not active), a trouble on the NAC circuits mapped to TB6 will
result in an open circuit condition on the control module output circuit (monitored by End-of-Line Resistor across TB6, Terminals 1
and 4). As an alternative, the trouble contacts at TB1 of the power supply can also be used for limited trouble monitoring excluding
faults reported by Command Input #2 related to Command Input#1 configured for Sync Input mode. Refer to Section 5 for more
information.
•
Refer to Section 3 for instructions on setting the DIP switches.
•
Output faults are reported via Command Input#2 with Command Input#1 configured for Sync Input mode operation.
•
Refer to the FACP manual for load restrictions and line length limitations when wiring multiple power supplies at the input.
•
Wire NACs as shown on page 13.
•
Do not loop wires under screw terminals. Break wires to maintain proper supervision.
•
An End-of-Line Resistor must be installed across all input circuits, Terminals 1 and 4, for control module wiring supervision (the
ELR value is dependent on the module/FACP employed).
