WRS-2224 Troubleshooting Guide

General Guidelines:

Make sure that 24V power exists (always measure between 22V and

30VAC);

Make sure all inputs and outputs are tightly connected;

Make sure all relay groups are programmed correctly;

If non-default input switching devices are used, make sure all inputs are

configured properly.

Problem Encountered

Flashing output LED(s)

during NORMAL mode

Output relay(s) not

tripping properly

FLICK WARN not working

TIME OUT not working

WRS-2224: Directions & Applications

Possible Cause(s)

Defective output relay

2 relays connected to same output

with one relay ON and the other OFF

External AC current leaking into circuit

Improper input voltage (must be

between 22V and 30VAC)

Input(s) not configured when non-default

input switching device(s) used

Relay(s) also part of another input group

with contradictory input signals

Relay(s) not included in input group

FLICK WARN not properly programmed

HID lighting used in FLICK WARN group

Inappropriate input switching device used

Relay group not programmed properly

TIME OUT assigned to more than one group

Corrective Action

- replace relay

- reset relays

- if either relay is in another input group,

remove it from that group

- check wiring

- check input configuration

- check input switching device(s) and connections

- check power source

- configure input(s) per instructions on page 6

- remove relay(s) from other group

- check programming, re-program if necessary

- use circuits with non-HID lighting

- make sure input is only ON during TIME OUT period

- use timer as input instead of switch

check programming, re-program if necessary

- assign TIME OUT only to one all-inclusive group
