Description: These connections are to the SPDT WARN relay. The WARN output is immediate
on the FL4000. The WARN output can be normally energized or de-energized, latching, or non-
latching. These options are also set via MODBUS or by a dipswitch (Section 3.7 ). The WARN
relay contact ratings are 8 A @ 250 VAC and 8 A @ 30 VDC.
Refer to Figure 20 for all relay connections.
3.6.3 Alarm
Wiring
Relay Protection
Inductive loads (bells, buzzers, relay, contractors, solenoid valves, etc.) connected to the
Alarm, Warn, and Fault relays must be clamped down as shown on diagrams in Figure 21.
Unclamped inductive loads can generate voltage spikes in excess of 1000 volts. Spikes of this
magnitude will cause false alarms and possible damage.

Refer to Figure 20 for all relay connections.
