MSA S5000 - Relay Configuration Options; Table 9 Relay Terminal Connections by Energy State

The Fault relay state cannot be reconfigured.
Relay Energy State and Terminal Connections
The S5000 relay states are labeled for the default de-energized state. The alarm/warning relay energy state can be changed on
the device, which will exchange the normally open and normally closed terminals. The preferred relay energy state should be
determined before making connections. Table 9 shows the terminal connections by energy state and is applicable to both
relay1 and relay2.
