OPERATION
6-2 April 3, 2000
C. Equalize Or Weekend Charge
The LTD 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 cancelled
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
(dV/dT or VT). 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 LTD Control. If a battery is left
connected to the charger for 48 hours after a “Charge
Complete” has been reached, the LTD 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 13 hours of charging.
Likewise, if the LTD Control is set to terminate via
the dV/dT methodology (DIP switch S1-7 off) and 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 LTD 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.
