adjust this knob when the charger is plugged in to a public outlet especially if there is no
easy access to the electrical panel for that circuit. Additionally, the user might need to
turn down the charger if there are other loads on the branch circuit (example: A stereo
and a computer are running on the same 15 amp circuit). If using a charger equipped
with the panel mount meter, the user can check the digital current meter on the front of
the PFC unit and see exactly how many amps the charger is drawing off of the AC line.
“LIMITS” - Yellow LED
The yellow LIMITS LED indicates that the charger has reached its peak voltage limit.
This should happen only at the end of the charge cycle when all the batteries are fully
charged. The LIMITS indicator should be accompanied by the blinking blue TIMER LED
which indicates that the charger is in current cutback mode and the timer is counting
down to the end of charge.
If the yellow LIMITS LED is blinking, then it is indicating that there is an over
temperature condition and the charger is in thermal cutback mode.
NOTE: When using regulators, the blue TIMER LED will often come on before the
LIMITS LED because the battery regulators let the charger know when the batteries are
getting full before the voltage limit is reached. If the LIMITS light is coming on frequently
or before most of the regs are blinking, this could be indicative of a few batteries whose
voltages are getting too high. It could also mean that someone has improperly adjusted
the VOLTS TRIM. Consult your battery regulator user’s manual or recalibrate the
VOLTS TRIM setting on the charger.
“TIMER” - Blue LED
The blue TIMER LED indicates that the charge is complete or near completion. If it is
flashing it means that charging is almost finished and the charger is backing off the
current and counting down the timeout timer. When the blue LED is steady, it means
that the timeout timer has ended and the charger has finished charging the pack. At this
point the charger should be putting out no power and drawing less than an amp off the
input line.
“TIMER ADJ”
This stands for timer adjustment. This is a small 16 position rotary switch which allows
the user to adjust the amount of time that the charger takes in constant voltage mode,
while cutting back current at the end of a charge cycle before it shuts off completely.
If the timer is ever to be changed, adjustments are as follows. If the switch is at ‘0’ then
the timer will time out instantly - do not use this setting. (‘0’ is the 3-o-clock position
when viewed from the front). If the switch is at ‘1’ it will go for 15 minutes before
completely cutting back power. Each additional tick after ‘1’ adds 10 more minutes to
the charge cutback time. Turning the switch clockwise all the way around to the 2:30
position will give the maximum amount of time (about 255 minutes) before timeout.
To reset the timer, turn off the power to the charger and then turn it on again.
