Acceptance Testing

NOTE: The controller may report a limited recharge alarm during these tests.
NOTE: At any time you encounter difficulty with these steps, refer to the Troubleshooting Section.
Communication with Rectifiers and Converters
Step
1 Place external battery disconnect switches in the ON (connected) position if equipped.
2 Turn on all circuit breakers supplying rectifiers.
Adjust the contrast (if needed) for the site's ambient condition
(Menu > Configuration > System Settings > Display Contrast).
3
Millennium II only: use the up and down arrow keys at the Main Menu.
Are all lit LEDs on all components including rectifiers, the controller, LVD control boards, and Aux Displays
Yes – Go to Step 7.
Initiate the Clear Events and Uninstall Equipment operations (in Menu > Control / Operations).
Non-existent alarm conditions should clear.
4
Refer to the controller manual as needed.
5 If the controller appears not to be powered or not responsive, remove and reseat the controller.
If all lit LEDs still aren't green, review the installation procedure or refer to the Troubleshooting section in this
manual. The controller display should indicate "NO ALARMS". The system float voltage, total load current, and
6
system operating mode should be observable as indicated and the controller's back-light shall be illuminated
green for no alarms and the system rectifier voltage should be displayed.
If Slope Thermal Compensation (STC) is active disable STC:
7
(Menu > Configuration > Batteries > Batt Temp Management > Temperature Comp)
Check the voltage readings on the controller display.
The controller is factory configured with a rectifier Float voltage set-point of -54.50V for -48V rectifier systems
and ±27.25V for ±24V rectifier systems. If converters are present, the display shows their voltage and current
in smaller font. The controller is factory configured with a converter output voltage set-point of -54.50V for -
8 48V converters and +27.25V for +24V converters.
Note: If Slope Thermal Compensation (STC) is active or if the connected batteries are not fully charged, the
bus voltage may be different than the set-point. If possible, open the external battery disconnect prior
to making measurements to eliminate these effects. If QS873 VT probes are installed in the system.
STC may be active. This will be indicated by the Plant Mode "FLOAT – TEMP COMP".
Enable Slope Thermal Compensation (STC) if it was disabled in Step 7:
9
(Menu > Configuration > Batteries > Batt Temp Management > Temperature Comp)
Remove and Replace Rectifier and Verify Results:
10 Remove a rectifier from its slot.
11 Verify the controller LED and display are light amber which indicates a missing rectifier condition.
12 When the controller prompts to remove, equipment press enter ■.
13 Verify the controller LED and display are light green.
14 Replace the removed rectifier in its original slot.
15 Verify the controller LED and displays remain green.
Repeat Steps 9-14 for converters, if equipped.
