5.After the fan has completely stopped spinning, insert a plastic pen or plastic screwdriver into the fan blade of one of the rectifiers and reinsert both rectifiers

6.Verify that you get the fan fail alarm on controller and the customer remote alarm panel.

7.Remove the fan fail device.

System Temperature Test

Verify that the system temperature is correct.

Battery Current Test

1.Measure the battery current with a clamp-on meter.

2.Verify that the battery current is below 5 A.

3.Verify that the displayed battery current is within + 5 A.

4.Determine the total battery capacity at the site:

Cells connected in series make up a string, and the capacity is determined by the capacity of a single cell. Add ampere/hour capacity for all strings connected in parallel.

5.Determine the Max. Batt. Recharge rate:

Divide Total battery capacity by 20 hours and enter it in the appropriate box on the Site Form.

6.Verify that the Max. Batt. Recharge rate is set to the calculated value.

7.Remove ac power to the rectifiers purposely causing the battery discharge alarm to come on.

8.Verify that the System Current is 0 + 5 A.

9.Verify that the battery current is within 5 % of the system current recorded previously.

10.Verify that the Battery Discharge Alarm is on.

11.Restore ac power to the rectifiers.

Battery Temperature Test

If the battery temperature probe is used in this system, verify that the battery temperature is correct.

LVD Test

1.Ensure that the LVD parameters are set to proper value.

2.Set the LVD Trip to –56.00 Vdc.

3.The LVD should have dropped out (opened). Verify it by monitoring the voltage at the battery connection.

4.Verify that the LVD Open Alarm is registered on the controller and at the customer remote alarm panel.

5.Reset the LVD Trip to negative (-) 42.00 Vdc.

6.Verify that the LVD Open Alarm has been removed.
