Lamp Test
Step
Depress LAMP TEST on the Millennium II controller display.
Verify that the LEDs on the rectifiers and controller illuminate.
Note: The green NORMAL LEDs will remain illuminated on the rectifiers, controller, LVBD and LVLD contactor
control boards (optional), and the remote peripheral monitoring modules (optional). The other controller
LEDs will extinguish after several seconds, and the remaining system LEDs will extinguish within
approximately 10 seconds.
Voltage Calibration
Note: DO NOT attempt to set the system voltage level using this procedure. The only purpose for this
procedure is to calibrate the display to the test jacks. Refer to "Setting the System
Voltage" (next procedure) for setting the system voltage level.
Step
Using a calibrated digital voltmeter (DVM), measure the system voltage from the test jacks (located on the front
panel of the Millennium II controller).
If the voltage on the controller display does not match the DVM reading, adjust the controller display. To move to
the correct screen to make the adjustment, follow the procedure below:
Use the keys to calibrate the system voltage to match the reading of the DVM. Press ENTER (Millennium II) to use
the new calibrated system voltage. Verify that the voltage reading at the test jacks now matches the controller
reading.
Setting the System Float Voltage
Step
Enter the appropriate key sequence:
Verify that the Very High and High alarm thresholds are set at least 0.5V above the float voltage to be specified in
Step 3.
Use the adjust keys to set the system float voltage. Enter the following M2 key sequence:
