QUICK START

Before permanently installing the WMS-T-AL it is advisable to “bench test” it to gain familiarity
with its operation. The test is conducted in the following manner.

Attach the temperature sensor leads to the terminals on the WMS-T-AL circuit board labeled
TMP1

and TMP2.

Attach 12V dc or ac to the terminals on the WMS-T-AL circuit board marked AC in/DC in and
AC in/DC gnd

.

When the WMS-T-AL circuit board is energized the LCD is activated and it will display the
temperature on the first line and the alarm set point values on the second line.

There are five control buttons next to the LCD. These are used to set the alarm thresholds for the
two alarms, to set the delay times between the time that the temperature crosses the alarm
threshold and when the alarm state changes conditions, and to clear the maximum and
minimum temperature value in the temperature log. The default condition for the temperature
alarms is 75°F.
Both the on-delay and the off-delay default values are 15 seconds.

To change the temperature alarm threshold value press the Menu button. The top line of the
display will change from “Temp XX.X (°F)” to “Temp Alarms (°F)”. Press the Menu button
again and the cursor moves over the Alarm 1 temperature value. Press the Up or Dn button to
increment or decrement the alarm threshold value for Alarm 1. Press the Go button to return to
the RUNNING mode. Repeat the process for Alarm 2.

To Change the Alarm On and Alarm Off delays, with the unit in the RUNNING mode press the
Menu

then press the Up button until the “Alarm Delays (s)” menu appears. Press the Menu

button and the cursor will move to the “ON: XX” field. Then Press the Up or Dn button to
increment or decrement the On delay value to the desired value. Press the Menu button again
to advance the cursor to the “OFF: XX” field and adjust the value with the Up or Dn button.
Press the Go button to return to the RUNNING mode.

To view the Minimum and Maximum Temperature registers from the RUNNING mode press
the Menu button, then press the Up button until the “Temps (°F)” screen is displayed and the
second line will show the minimum and maximum temperatures obtained since the last reset.
To reset the maximum wind speed value to zero press the Clr button. Press the Go button to
return to the RUNNING mode.

This concludes the series of quick start tests.
