Battery Temperature Test
If the battery teperature probe is used in this system, verify that the battery temperature is correct.
LVD Test
1.Verify that the Battery Float voltage is set to negative
2.Enable the LVD’s that are installed.
Note: In
3.Ensure that the LVD parameters are set to proper value.
4.Install rectifiers and restore AC power.
5.Set the LVD Trip to
6.The LVD should have dropped out (opened). Verify it by monitoring the voltage at the battery connection.
7.Verify that the LVD Open Alarm is registered on the controller and at the customer remote alarm panel.
8.Reset the LVD Trip to negative
9.Verify that the LVD Open Alarm has been removed.
Battery Preventive Maintenance Procedure
The purpose of the preventive maintenance is to ensure that the battery is in good, working condition. The observations, measurements, and tests performed are designed to determine the “state of health” of the battery. It will also allow for the prediction of future performance and preempt possible failure.
1.Measure the float charge voltage.
a.At the power bay bus.
b.At the battery.
c.Reset voltage if necessary.
2.Measure the float current on each battery cable. If it is fluctuating, measure maximum and minimum.
3.Measure the AC ripple voltage at the battery.
4.Using an Alber Cellcorder, measure the float voltage of each cell or monoblock. Record the battery memory location allocated on the Cellcorder.
5.Using an Alber Cellcorder, perform a load test on each cell or monoblock and measure the internal cell resistance and
6.Measure and record the specific gravity of each cell using an individual hydrometer or Cellcorder attachment hydrometer (VLA only).
7.Ensure that the electrolyte level is adequate. Add approved water where necessary (VLA only).
8.Measure and record the temperature of the electrolyte of each cell (VLA only).
