The reed relay output provides both N.O. (normally open) and N.C. (normally closed) dry contacts in
order to interface as universally as possible. Typically the Relay N.O. and Relay Common terminals will
be connected in parallel to those of other "coin pulse" generating devices. The Relay Common contact has
an automatically resettable fuse to protect the module from wiring errors and other problems. The Service
Monitor input is used to sense if power to the equipment has been applied. The Wicket Reader monitors
this signal to determine the following; a) whether to charge the Start Up Amount or the Increment
Amount, or b) whether to indicate that the equipment is running (Wicket Reader face turns white).
Wickets Administrator is used to configure the WR88 Wicket Reader's use of this signal, including
enable/disable and whether Service Sense logically corresponds to a high or low voltage sensed at the
input.
One of the below wiring harnesses must be ordered with the WK-LV Module for field wiring:
The WK-WR-LV wire harness has 16" leads and is intended
for general purpose retrofit interface. IDX can assist you with
specific information on connecting to a variety of equipment.

Note: Wickets Administrator must be used to program the WR88 Wicket Reader to enable it to generate
the correct pulses and debit a Customer Wicket by the proper amount. See below for information about
setting the configuration parameters for the WR88. A separate PDF document for Maytag-specific setup
instructions is available on the Web.
