4.5 Failsafe Alarm Relay Wiring and Specifications
The “Failsafe” output relay is provided to signal critical error conditions that may occur on the RSG2200 series products. The contacts are energized upon power up of the unit and remain energized until a critical error occurs. The proper relay connections are shown in Figure 19. One common application for this output is to signal an alarm if a power failure or removal of control power occurs.
