3.3 Operation and Adjustment

All operating adjustments are made at the front panel of each rectifier. The following components are located on each rectifier panel:

1.Float voltage adjustment

2.Current limit adjustment

3.Current test points

4.Alarm indicators

Figure 3 shows different indicators and adjustment points on this unit.

Rectifier adjustments must be done sequentially from the first through the fourth rectifier with AC applied. All adjustments must be made with no load, and the batteries disconnected to ensure adjustment accuracy.

3.3.1 Start-Up

To start up the system, perform the following steps:

1.Aproximately 3 to 8 seconds after the AC applied, the RFA LED extinguishes.

3.3.2Float Voltage Adjustment

Verify the required float voltage setting per battery manufacturer specification. If the factory setting differs from the battery manufacturer recommended setting, the ALU float voltage parameter and each rectifier’s float voltage must be adjusted to the new setting. A digital multimeter and a small screwdriver are required to perform this procedure. Located the float voltage access point (FL) at the front of the rectifier.

To adjust the float voltage, perform the following steps:

1.Remove the ALU.
