Testing the Control

The control has a built-in test routine that tests the main
control functions. The control continually monitors the
sensors and displays an error message whenever a fault
is found. The individual outputs and relays are tested using
a test sequence.

Test Sequence

Each step in the test sequence lasts 10 seconds.

• Start the test sequence by pressing the Test button.

• Pause the test sequence by pressing the Test button

again. To advance to the next step, press the Test button
again.

• If the test sequence is paused for more than five minutes,

the control exits the entire test routine.

• To advance to a particular step, repeatedly press and

release the Test button to display the appropriate
device.
