TEST PUSH BUTTON
The test push button is located on the front panel. The test push button has the following three
functions:
1. Mute: Pressing the button less than 2 seconds causes the spare relay to de-energize.
2.
LEDs/Output Test: Pressing the button more than 2 seconds causes all the relay outputs to
energize and LEDs to light.
3.
Communication test: Double clicking the button will cause the communication link to be tested. If
test pass, all the LEDs of the MAC-32-OD will flash three times. If test fails, only LED 1 flashes
three times.
