A TEST button is located on the front of the module. When you press and
hold this button, the module enters test mode. Two tests are run.
1. Lamp / LED Test
All push button lamps and red/green LEDs turn OFF for one second, then
illuminate for two seconds. If you press the TEST button when the test is
done, the module continues with the Push Button Contact test.
2. Push Button Contact Test
Push buttons react as shown in Table 5A.
Selector switches react as shown in Table 5B.
During TEST mode, the status of the lamps are not updated, and any push
button presses are not transmitted to the PLC. The module exits test mode
two seconds after you release test button.
