Battery charger calibration procedures CA1
A. Equipment Setup:
Perform the following calibration procedures, setup the equipment as followings:
1. Adjustable Electronic Load, 30A 30VDC or above.
2. Digital Multi-Meter (DVM).
B. Calibration procedures:
1. Check insulation tape must good condition on the heatsink both sides. Replace new tape
if any damaged.
2. Re-assembly the parts as per assembly drawing AS1 carefully.
Connect CN2, CN3 and CN7 onto the PC board but keep the cover open until the
calibration procedures are completed.
3. Select the battery selector to “GEL” and the Voltage selector to 13.2VDC
4.
Connect the DC Electronic Load (+) to the charger output (+), the DC Electronic Load (-)
to the charger output (-).
5. Connect the DVM (+) to the charger output (+)., DVM (-) to the charger output (-).
6. Set the DC Electronic Load to “zero” , connect the Charger to 230VAC, the CHARGER
ON
And FLOAT LED should light up. If not back to page TS1.
7. Set the DC Electronic Load to “5A”, the CHARGER ON and ABSORPTION LED will light
up. If the ABSORPTION LED is not light up then adjust the VR5 to keep the
ABSORPTION LED light up.
8. Switch the battery selector from “GEL” to “FLOODED”, the DVM should read between
14.4~14.8VDC. If not then adjust the VR2 to get the reading between 14.4~14.8VDC.
9. Switch the battery selector to “GEL”, the DVM should read between 14.0~14.4VDC, if not
then adjust the VR3 to get the reading between 14.0~14.4VDC.
10. Set the DC Electronic Load to “1A”, the CHARGER ON and FLOAT LED will light up. the
DVM should read between 13.0~13.4VDC. If not then adjust the VR4 to get the reading
between 13.0~13.4VDC.
11. End of calibration, re-assembly the cover.
