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 Action
1.
Place external battery disconnect switches in the ON (connected) position if equipped.
2. Turn on all ac circuit breakers supplying rectifiers.
3.
Adjust the contrast (if needed) for the site’s ambient condition by using the up and down arrow
keys at the Main Menu.
After approximately 30 seconds, are all lit LEDs on all components including rectifiers, the
controller, LVD control boards, and Aux Displays green?
Yes – Go to Step 7. No – Proceed to Step 4.
4.
Initiate the “Clear Events” and “Uninstall Equipment” operations found under MENU >
CONTROL / OPERATIONS
menu. Reference to Appendix A: Pulsar Controller User
Interface as needed.
5.
If the controller appears not to be powered or not responsive, verify +24V between C and V1 test
points.
6.
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 “0 ALARMS”. The system float
voltage, total load current, and system operating mode should be observable as indicated for no
alarms and the system rectifier voltage should be displayed.
7.
If Slope Thermal Compensation (STC) is active, turn off STC using the front panel keypad to
follow this sequence: Menu>Configuration>Batteries>Battery Temp Management>Temperature
Comp>Disable> Save
8.
Check the voltage readings on the controller display.
The Pulsar is factory configured with a rectifier Float voltage set-point of -54.50V
Note that if STC is active or if the connected batteries are not fully charged, the voltages may be
lower.
(If possible, open the external battery disconnect prior to making measurements to eliminate
these effects. If QS873 temperature probes have all ready been installed in the system, then STC
may be active. This will be indicated by the Plant Mode “FLOAT – TEMP COMP”.)
9.
If no Thermal Probes are present, leave Slope Thermal Compensation disabled; otherwise,
Enable Slope Thermal Compensation using the front panel keypad to follow this sequence:
Menu>Configuration>Batteries>Battery Temp Management>Temperature Comp>Enable> Save
Remove and Replace Rectifier and Verify Results:
9.
Remove a rectifier from its slot.
10.
Verify the controller LED and display light amber and indicate a missing rectifier condition.
11. When the controller prompts to remove equipment press enter ■.
12.
Verify the controller LED and display light green.
13. Replace the removed rectifier in its original slot.
14. Verify the controller LED and displays remain lit green.
