3.3 Failsafe Alarm Relay Wiring
The “Failsafe” output relay is provided to signal critical error conditions that may
occur on RX1000 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 16. One common application for this output is to signal an alarm
if a power failure or removal of control power occurs.
