13. TROUBLESHOOTING AND SERVICING
CAUTION: DO NOT OPERATE THE CHARGER IF IT IS DAMAGED OR APPEARS TO BE
MALFUNCTIONING. PERSONAL INJURY OR DAMAGE TO THE CHARGER OR BATTERIES MAY
RESULT. INCORRECT REASSEMBLY AFTER SERVICING THE CHARGER MAY RESULT IN RISK OF
ELECTRIC SHOCK OR FIRE.
The charger was fully tested and calibrated before leaving the factory. It was delivered ready to charge. If
properly installed, the charger should require very little attention. If improper charger operation occurs, follow
the step below.
Ensure that the “AC PRESENT” LED on the UIM is illuminated; indicating that AC input power is
present.
Check the “ALARM” LED on the UIM. If this LED is illuminated, refer to Section 11.1 in order to
determine which alarm(s) is active.
Check the “NUMBER OF CELLS” and “VOLTS PE R CELL” rotary switches on the UIM to verify their
settings against the specifications of the batteries. If the “NUMBER OF CELLS” rotary switches are
set to “00”, which enables software control of the float voltage value, refer to Section 11.3 in order to
verify the “Number of Cells” and “Float Voltage Per Cell” setting values via the charger web server.
Check the AC input and DC output fuses to make sure they have not blown.
Open the access panel on the front of the charger and make sure all of the binding posts nuts are
tight.
Check the polarity between the DC output terminals and the battery pack and make sure all
connections are tight.
Refer to Section 11 in order to verify all other charger web server settings.
If the steps above do not solve the issue and you are qualified to do additional investigating of the
issue then see the section of ATLAS Charger Troubleshooting chart (see section 13.1) to assist with
the troubleshooting. The charger wiring diagram (see section 14) can also be used to help in
determining the cause of the issues.
If the steps above do not solve the issue, contact Lester Electrical service agent at 1-402-477-8988.
