System Overview
Switch SW1 - Ground Fault Detection
1.5 Switch SW1 - Ground Fault Detection
The Ground Fault Detection circuit monitors for ground faults. Switch SW1 is located on the lower left section of the power supply cir-
cuit board. Sliding SW1 to the left will disable ground fault detection by the power supply. This should only be done if ground faults are
being monitored by an FACP connected to the FL-PS power supply or in a cascading application as shown in Section 2.8 on page 18.

Programming DIP Switches
Activate output DIP switch changes by setting S1 positions 9 and 10
appropriately. Refer to page 24 for DIP Switch programming settings.
Each output circuit has its own dedicated programming DIP switch

Note:
The FL-PS6 uses the same PCB
layout, however some terminals will be
depopulated, leaving the FL-PS6 with five
output circuits and two inputs circuits.
