10.2 Low Voltage Start
The Low Voltage Start button manually starts a charge cycle for a battery with a voltage too low to
automatically start (as low as 1V). You should press and hold the button for 5 to 10 seconds. If the battery
voltage is 1V or above, the Charge Status LED will begin blinking while you are holding the button. If the
Charge Status LED stops blinking after you release the Low Voltage Start button, repeat pressing and
holding the button for another 5 to 10 seconds.
10.3 Self Diagnostic and Faults
The Self Diagnostic button should be used when you suspected that the charger is not functioning properly.
Pressing this button initiates a self diagnostic test. A properly-sized battery that is not overly discharged
must be connected to the charger for the self diagnostic test to execute. The Self Diagnostic and Charge
Status LEDs indicate the result of the self diagnostic. Figure 9.3-1 lists the possible combinations of LED
states and the respective self diagnostic results that they indicate. The self diagnostic results are explained
below. If a fault occurs while the charger is in use, the same results will be indicated using the Self
Diagnostic and Charge Status LEDs. In the event that the self diagnostic returns a result other than “Self
Diagnostic Passed”, contact a qualified service technician, and provide them with the self diagnostic result.

Figure 9.3-1: Self Diagnostic Results
Self Diagnostic Passed
The self diagnostic test was successful, and no issues were identified with the charger.
Battery Voltage
The DC battery voltage is too low (low-battery condition or incorrectly-sized battery) or too high (incorrectly-
sized battery). Connect a battery that is not overly discharged with a cell count (CELLS) and DC voltage
(DC VOLTS) equal to those listed on the charger ratings label to the charger, and press the Self Diagnostic
button again.
-OR-
A timer fault has occurred. For example, the maximum charge cycle timer has expired or the maximum
allowable amp-hours returned has been reached. Ensure that a battery in good working condition with an
amp-hours rating (AMP-HRS) within the range listed on the charger ratings label is connected to the charger.
Control Board
The control board is not functioning properly.
Current Sense
The current sense is not functioning properly.
AC Input
An AC input issue exists. Ensure that the charger AC power cord is connected to a single-phase, 120V, 60
Hz outlet that is properly powered. Ensure that the charger AC circuit breaker on the user interface has not
tripped. If it has, press to reset it. Otherwise, the charger is not functioning properly.
