XWA11V-KIT
Walk-In Temp / Door /Alarm / Light Module with Mounting Box and Wiring
1. GENERAL DESCRIPTION
Model XWA11V-KIT, 100x64 mm format, is a microprocessor based light and alarm management controller, suitable for
temperature monitoring in a walk-in cooler or freezer. It is provided with two (2) relay outputs that supply 120 Volts to
control lights and signal an alarm. It is also provided with one (1) NTC probe input for temperature measurement. To
ease installation on existing walk-in coolers the unit has been installed in a VBOX pre-wired with an outboard buzzer,
magnetic door switch (MDS), a 9V battery harness, a pigtail harness for the unit power and the light. There is also a five
pin port that allows the user to program the parameter list with a “Hot Key”.
Note: The default settings are listed in the back of this manual. They are set for Coolers (Medium
Temp). For Freezers (Low Temp) you MUST Change the ALL and ALU settings.
We have responded to many requests to make a change in the way the light key operates. It now
overrides the Digital Input to allow a manual OFF prior to the “Lht” being exhausted.
See Section 4.0
2. GENERAL WARNINGS
2.1 PLEASE READ BEFORE USING THIS PRODUCT
This manu
reference.
The instrument shall not be used for purposes different from those described hereunder. It cannot be used
as a safety device.
Check the applicatio n limits before proceeding
2.2 SAFETY PRECAUTIONS **READ ME FIRST!**
Check if the supply voltage is correct before connecting the instrument.
Do not expose the back of the instrument to w ater or moisture: use the controll er only within the operating limits
avoiding sudden temperature changes with high atmospheric humidity to prevent the form ation of condensation.
Be sure to seal any J-Box with RTV sealant to prevent cold and moisture intrusion.
Warning: disconnect all electrical connections before performing any maintenance operation.
Fit the probe where it is not damaged by the end-user. The instrument must not be opened.
In case of failure or faulty operation send the instrument back to the distributor (see address) with a detailed
description of the fault.
Consider the maximum current that can be applied to each relay (see Technic al Data).
Ensure that the wires for probes, loads and the power supply are separated and far enough from each other,
without crossing or intertwining or you may get bad temp readings.
The box supplied is not suitable for exterior use. If a water tight box is required co ntact the distributor.
al is part of the product and should be kept close to the instrument for easy and quick
