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”.

2. GENERAL WARNINGS

2.1 PLEASE READ BEFORE USING THIS MODULE

• This manual is part of the product and should be kept close to the instrument for easy and quick reference.

• The instrument shall not be used for purposes different from those described hereunder. It cannot be used as a safety device.

• Check the application limits before proceeding.

2.2

SAFETY PRECAUTIONS

• Check if the supply voltage is correct before connecting the instrument.

• Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden temperature changes with high atmospheric humidity to prevent the

formation of condensation.

• Warning: disconnect all electrical connections before performing any maintenance operation.

• Fit the probe where it cannot be 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 Technical Data).

• Ensure that the wires for the probe and digital inputs, are separated and far enough from loads and the power supply without crossing or intertwining. (UL SPEC 0873)

• The box supplied is not suitable for exterior use. If a water tight box is required contact the distributor.

4. TEMP ALARMS SETTING

4.1 HOW TO SET THE MIN TEMPERATURE ALARM

• To modify the minimum (LOW) Temp ALARM: press the

+ keys for 3s until the minimum Temp alarm is displayed.

• Change the value using the UP and DOWN keys.

• Press the SET key to confirm the new value and exit.

4.2 HOW TO SET THE MAX TEMPERATURE ALARM

• Change the value using the UP and DOWN keys.

• Press the SET key to confirm the new value and exit.

5. PROGRAMMING

5.1 HOW TO CHANGE A PARAMETER VALUE MAIN MENU

1. Enter the Programming Mode by pressing the SET and DOWN key for 3s ( and start blinking).

2. Select the required parameter.

3. Press the “SET” key to display its value (now only the LED is blinking).

4. Use “UP” or “DOWN” to change its value.

Press “SET” to store the new value and move to the following parameter.

To exit: Press SET + UP or wait 15 s without pressing a key. NOTE: The set value is stored even when the procedure is exited by waiting for the time-out to expire.

5.2 THE HIDDEN MENU (PR2)

The hidden menu includes all the parameters of the instrument.

5.2.1 HOW TO CHANGE A PARAMETER VALUE MAIN MENU

1. Enter the Programming Mode by pressing the Set + down key for 3s ( and starts blinking).

2. When a parameter is displayed, release and re-press the SET + down for more than 7s.

3. The Pr2 label will be displayed immediately followed from the HY parameter. NOW YOU ARE IN THE HIDDEN MENU.

4. Select the required parameter.

5. Press the “SET” key to display its value (Now only the LED is blinking).

6. Use “UP” or “down” to change its value.

7. Press “SET” to store the new value and move to the following parameter.

To exit: Press SET + up or wait 15s without pressing a key.

NOTE: The set value is stored even when the procedure is exited by waiting for the time-out to expire.

5.2.2 HOW TO MOVE A PARAMETER FROM THE HIDDEN MENU TO THE FIRST LEVEL AND VICEVERSA

Each parameter present in the HIDDEN MENU can be removed or put into “THE FIRST LEVEL” (user level) by pressing “SET + down”. In HIDDEN MENU when a parameter is also present in First Level the decimal point LED is on.

5.3 HOW TO LOCK THE KEYBOARD

1. Keep the UP and DOWN keys pressed for more than 3s.

2. The “POF” message will be displayed and the keyboard will be locked. At this point it will be possible only to see the Set Point or the MAX or MIN Temp stored.

3. If a key is pressed more than 3s the “POF” message will be displayed.
