INITIAL SET-UP & DESCRIPTION
Set-Up
See Location Diagram of Selector Switches included in
this manual.
For proper operation, the LTD Control must be set to
match the charger in which it is installed.
Cell Size Selection
From the data plate on the charger, note the voltage
output. Place the corresponding DIP switch (S1) on the
LTD Control in the “Closed” position.
S1-1
12 Volts
S1-2
24 Volts
S1-3 36 Volts
S1-4
48 Volts
S1-5
Optional
Only one of the above DIP switches should be in the
“Closed” position at any one time.
Auto Equalize
Switch S1-6 can be used to select either Auto Equalize
or Manual Equalize.
Termination Type
Switch S1-7 can be used to select either dv/dt charge
Termination or VT.
6-Hour Termination Type
Switch S1-8 can be used to select the 6-Hour charge
after 80% Termination.
Description
The LTD Control has an on board microcontroller to
monitor and control the charging process. The
up-to-date status of the charge cycle can be easily
monitored by watching the status of the four LED’s,
charge in progress, 80% charged, charge complete,
and equalize. The LTD Control utilizes either a
Voltage/Time (VT) charge termination or a
patented pt/dV/dT charge termination technique
which eliminates excessive gassing by returning
approximately 107% of the amp-hours removed
from the battery. All front panel information
(including operating instructions) is back printed
on a polycarbonate overlay which is resistant to
damage from oils, gasoline, and frequent operator
handling. The LTD Control is “matched” to the
output voltage of the charger by means of a printed
circuit board mounted DIP switch. Features of the
LTD Control include Auto start/stop, Auto/manual
equalize, Manual Stop, Backup timer protection,
Two charge termination methods, 2.37 V/C 80%
point, 48 Hour Refresh, and AC power fail recovery.
