Adjusting Test/Equalize Output Voltage
Local MCA Control Panel Adjustment Procedure
1. All controls are located on the MCA Interface Pad. Refer to Figure 1.
2. With "SYSTEM OK" being displayed on the MCA Interface Pad, press and release the FUNCTION SET
ENTER pushbutton.
or

9. Observe the value displayed. This is the test/equalize voltage setting for all Rectifier Modules, assuming
50% load. To change this value, press and hold the FUNCTION SET YES (+) or NO (-) pushbutton.
Release the pushbutton when the desired value is displayed.
NOTE! The test/equalize voltage value is prevented from being adjusted higher than 0.5V below the
high voltage shutdown setting. When used with a Battery Charge Digital Temperature Compensation
Probe, test/equalize voltage is prevented from being adjusted higher than the Maximum Voltage with
Temperature Compensation setting, or lower than the Minimum Voltage with Temperature
Compensation setting.
The MCA is used in various applications, equalize voltage cannot be adjusted beyond the limits of the
Rectifier Module.
10. With the desired test/equalize voltage value being displayed, press and release the FUNCTION SET
ENTER pushbutton.
