QUICK START PROCEDURE
7. Measure the voltage from the VH test point to ground.
The voltage should read approximately 1.52V.
8. Measure the voltage from the VL test point to ground.
The voltage should read approximately 0.95V.
9. With JP1 set to CONT, JP2 set to EN, JP3 set to 1 and
JP4 set to 1, observe that the BATX and BATY LEDs
are cycling through their four states.

10. Decrease PS1 and PS5 to 9.4V and observe that while
the BATX and BATY are off, the
UVFLT
LED is on.
11. Increase PS1 and PS5 to 15.9V and observe that
while the BATX and BATY are off, the
OVFLT
LED is
on. Decrease PS1 and PS2 to 12.0V.
12. Decrease PS2 to 11.5V. Set JP1 to TIMER. Observe
that the BATX LED is off and BATY LED is on the ma-
jority of the time. Increase PS2 to 12V and observe
that the balancing action stops. The BAL LED will be
off and the DONE LED will be on.
13. Set JP1 to CONT and JP2 to SD. Set PS5 to 11.8V.
Observe that balancing action has stopped and no
LEDs are on. Set JP2 to EN and observe that balancing
action starts.
14. Turn off all power supplies.
