BASIC DISCHARGER INSTRUCTIONS

The following are brief instructions to program the Lester
36/48 Discharger Unit for use on RANGER EV 48 volt
battery systems. These instructions are for basic set-up
only. Refer to instructions provided with the discharger
unit for a complete guide to other features and
information. The following applies only to the Lester 36/
48 model discharger unit which is the recommended
discharger for the RANGER EV.
PROGRAMMING INSTRUCTIONS
The following list of functions and what they represent is
printed on the front panel of the discharger unit.

Display Functions
Present Battery Voltage
Func1
Discharge time in minutes and seconds.
(Minutes are displayed on the left and
Func2
seconds to the right of the decimal point).
Lowest battery voltage reached during
Func3
discharge
Battery voltage sensed (36 or 48)
Func4
Discharge data printout interval.
Func5
(Number of seconds)
The two functions that must be verified or reset are:
• Maximum Discharge Time
• Shut-off Voltage
NOTE: Values for the above variables can be
changed at any time, even while a discharge cycle is
running.
Changing The Maximum Timer
The default discharge time is 240 minutes. This value is
the maximum amount of time the discharge unit allows to
discharge a set of batteries. Do not set the Maximum
Timer below 200 minutes.
To INCREASE the maximum timer (if it has been
decreased from the 240 minute default value to a value
below 200 minutes):
1. Press and release the DISPLAY button until Func1 is
displayed.
2. Continue to hold in the DISPLAY button while you
press and release the START/STOP button. Every
time you press and release START/STOP the
maximum timer will increase by 5 minutes. When the
setting is at least 200 minutes, release the DISPLAY
button.
Changing The Shut-off Voltage
When the discharge unit is powered up it will
automatically decide whether to discharge at the 36
or the 48 volt rate. If the discharger senses a voltage
above 42 volts, a 48 volt discharge will begin (56.25
amp rate) and the shut-off voltage will default to its
lowest programmable value of 42 volts.
The time and voltage minimums specified in this
manual are for a 42 volts shut-off. Do not change this
setting to a different value.
To check which type of battery set the discharger has
sensed:
3. Press and release the DISPLAY button until you see
the value of Func4 before you press the START/
STOP button. The voltage sensed by the discharger
should be 48 volts, and the shut-off voltage will be 42
volts.
