Section 3.3
Critical Alarm Wiring
The Critical Alarm output relay signals critical error conditions that may occur on the RuggedBackbone™
RX1501. The contacts are energized upon power-up of the unit and remain energized unless a critical alarm
condition is detected. Relay connections are shown in the
Critical Alarm Relay Connector
diagram. You can
configure control of the relay output through the ROX user interface.
A common application for this output is to signal an alarm in case of a power failure.
