OPERATION
C. Equalize Or Weekend Charge
The Control features Auto Equalize on every 5th
charge cycle. Closing S1-6 can disable the feature.
When the Auto Equalize feature is disabled, an
Equalize charge can be selected or de-selected for
any charge cycle
using the sequence below.
1. Insure the battery size matches the charger.
(Number of cells and ampere-hour capacity are
within charger nameplate rating.)
2. Securely engage the battery and charger
connectors.
3. After a 5 second delay (all LED’s will be lit), the
charger will turn on. The “Charge in Progress”
LED will indicate charging current.
4. Press the “EQUALIZE” key. The “Equalize” LED
will light solid. Press the key again to cancel the
equalize charge.
NOTE: The equalize charge cannot be can-
celled
once the battery reaches the equalize charging
period. Press the STOP key to terminate the
charge.
5. The “80% CHARGED” LED will light when the
battery on charge reaches the 80% charged
voltage.
6. The battery reaches the normal termination
point.
However, the battery is charged another 3 hours.
The “Equalize” LED will flash during this equalize
period.
7. The charger will automatically turn off, and the
“Charge Complete” and the “Equalize” LED will
light when the equalized charge has finished.
The LEDs will remain on until the battery is
disconnected from the charger.
WARNING: DO NOT connect a battery to
this charger if the “Charge in Progress” LED
is lit. Do not disconnect a battery from this
charger while a charge is in progress;
otherwise, arcing and burning of connector
parts or a battery explosion may result.
Batteries produce explosive gases. Keep
sparks, flame, and cigarettes away.
Ventilate when charging in an enclosed area.
Always shield eyes when working near
batteries.
D. Manual Stop
1. To turn the charger OFF during any part of a
charge cycle, press the STOP key. All four
LEDs will flash.
2. To restart the charger, disconnect and
reconnect the battery. A new charge cycle will
begin.
E. Refresh Charge
In order to guarantee that a fully charged battery
is
always ready for use, a “Refresh” feature has
been incorporated into the Control. If a battery
is left connected to the charger for 72 hours after
a
“Charge Complete” has been reached, the Control
will start a charge sequence. The running time of
this “Refresh” charge will depend on the depth of
self-discharge of the battery.
F. Back-up Timer Shutdown
A back-up timer will shut down the charger and all
4 LEDs will flash then the “Charge Complete” LED
will flash if the battery on charge does not reach
the 80% voltage during the first 10 hours of
charging.
Likewise, if the charger does not reach the
termination point within 5 hours after reaching the
80% charged voltage, all 4 LEDs will flash then
the
“Charge Complete” LED will flash.
G. Battery Disconnect Shutdown
If the battery is disconnected from the charger
during a charge cycle, the charger will be shut
down. All LEDs will be off.
H. AC Power Failure
During an AC power failure, the Control stores
key information about the charge cycle. The
information is retained by powering some of the
control’s key components with a battery derived
power supply. This causes the control to resume
the charge where it left off when the AC power is
returned, unaffecting timers and equalize
requests.
