Test 020 - APS Power Supply Test
This test is intended for use by APS bench test technicians. This test
overrides conditions that would normally shut down the APS, thus
allowing readings and circuit adjustments.
When test 020 is executed, the lamp will ignite. If the lamp is off, the
ignitor board will pulse until the lamp is lit or the switch setting is changed.
If the lamp is in standby mode (test 021), it will be returned to full
intensity. When the lamp is lit, arc power supply indicators LAMP ON,
START, and IPRES should be lit; SHORT and STANDBY should be out.
The hour meter should be running and the fan running on high speed.

Notes:
•
Once test 020 is executed, the lamp self-start mode is activated. Every
time a new test is entered, the lamp will self-start. Every time a test is
exited, the lamp will douse. This can be very damaging to lamps. It is
best to leave a lamp lit 20 minutes after starting. At least, let it run for
5 minutes.
•
To run a test with the lamp lit, enter test 020, let it run for 5 minutes,
and then go to the desired test. The lamp will douse on exiting test 020
and re-start after entering the next test. To douse the lamp for further
tests, enter test 022 and the lamp self-starting mode will be exited.
