Application Examples 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 PSE 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 PSE
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 PSE 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).
• For a list of compatible devices, refer to the Notifier Device Compatibility Document #15378.
• Refer to the SLC Wiring Manual for more information.
