Figure 4–4: SETPOINTS PAGE 3 – OUTPUT RELAYS
NON-FAILSAFE:
The relay coil is not energized in its non-active state. Loss of control power will
cause the relay to remain in the non-active state; i.e. a non-failsafe alarm or trip
relay will not cause an alarm or trip on loss of control power. Contact configura-
tion is shown in Figure 2–3: TYPICAL WIRING DIAGRAM on page 2–4 with
relays programmed non-failsafe, control power not applied
FAILSAFE: The relay coil is energized in its non-active state. Loss of control power will cause
the relay to go into its active state; i.e. a failsafe alarm or trip relay will cause an
alarm or trip on loss of control power. Contact configuration is opposite to that shown
in Figure 2–3: TYPICAL WIRING DIAGRAM on page 2–4 for relays programmed as
failsafe when control power is applied
