4 Test Menu
All equipment is shipped from the factory fully tested and operational. As part of planned maintenance,
customers may want to be able to re-test functionality of the alarm LEDs and relays. The test menu allows the
customer to test both the LEDs on the display card as well as any alarm relay contacts.
4.1 Test LEDs
The Test LEDs menu allows the customer to run a basic lamp test on the A77. After selecting this menu press
the “ENTER” button to light all of the LEDs on the display membrane. To end the LED test press the LEFT
button.
 
Note that any additional LEDs on auxiliary boards will not be affected by this LED test.
4.2 Test Relays
The test relays menu allows the customer to test the functionality of the alarm relay contacts. The menu allows
for each contact to be tested individually, or all at once. When a relay is being tested, its contacts will change
state. This means if a relay is in alarm state, it will revert to the non-alarm state during relay testing.

When an alarm relay is being tested, the corresponding LED on the membrane will change state. There is no
relay contact for the “OVERLOAD/CURR. LIMIT” alarm. This LED will not be lit under the relay test. As with the
LED test, once the appropriate selection is made, press the ENTER button to start the test and the LEFT button
to end the test.
If the charger was not supplied with the 46R option package, the alarms relays specific to the S2A-198B alarm
card will not be shown in the “Test Relays” menu.
