OWNER'S MANUAL
Description and Features: This unit is an Intelligent, microprocessor based,
panel mounted battery voltage monitor for display of the State of Charge of 12V / 24V
battery with the help of buzzer and different patterns of Red / Yellow / Green LEDs: steady
/ blinking / slow or fast “Walking LEDs”. 12V / 24V battery is detected automatically when
voltage of 7 to 32V is seen on connection of the battery. Following parameters / conditions
are displayed:
•Terminal voltage
•
Charging in progress
•
Alarm at programmed low voltage threshold.
•
Alarm at programmed high voltage threshold
•3- Day Timer / Switch OFF the unit for low voltage protection
Threshold (14.8V (Preset) / 15.3V / 16V for 12V battery and 29.6V (Preset) / 30.6V /
32.0V for 24V battery). The loop is: (Red » Yellow » Green» All OFF)… repeats this
sequential loop.

High Voltage Alarm during Charging:
Following voltage thresholds can be
programmed to warn about over voltage condition during charging (See programming

This facility can be used to indicate onset of “Equalization Stage” when charging Flooded
/ Wet Cell Batteries. During “Equalization Stage”, the battery is intentionally overcharged
to 15.3 to 16V (12V battery) / 30.6 to 32V (for 24V battery) for limited time of 1 to 3
Hrs. During this time, it is necessary to monitor the battery for overheating / electrolyte
level / measurement of individual cell voltages and for turning OFF Equalization at the
appropriate time.
Installation: Please refer to Figs 1 and 2 above. The unit consists of a 65 x 65 mm
front plate with 4 x 3.2 mm holes for flush mounting on a wall / panel with 4 screws (#4,
Tapping, Flat Head). The Printed Circuit Board (PCB) and Battery Input Connectors (0.25”/
6.3 mm Quick Connect Tabs) are located at the back of the plate and project out to a
depth of 25.5 mm. For flush mounting on the wall / panel, a pocket / slot measuring 30
mm x 30 mm x 40 to 50 mm depth is required to be made to accommodate the projection
at the back.
Use AWG # 22 to 26 wires (e.g. telephone wires) to connect to the battery (See
Fig. 2). Use a 0.5A fuse in series with the Positive wire. The fuse should be as close as
possible to the battery Positive terminal (preferably within 7”).
Refer to Fig 2. Battery Positive (+) and Negative (-) connections to the unit are made
through Battery Input Connectors “A” and “B” (1/4”/6.3 mm Male Quick Connect Tabs).
For this connection, use 0.25”/6.3 mm Female Quick Connect Receptacle Terminal Lugs on
the wire ends (See Fig 3).
12V / 24V battery is detected automatically when voltage of 7 to 32V is seen on
connection of the battery. At startup, Red LED is activated as a sign of power up. After
some time, the unit is initialized and 12V / 24V battery is recognized. The State of Charge
is displayed thereafter.
LED and Buzzer Indications for Voltage Levels:
*NOTE
: Term “Walking LEDs” has been used to indicate cyclical, sequential lighting
pattern of Red, Yellow and Green LEDs. This pattern indicates that charging is taking
place. Following 2 patterns are used:
•
“Walking LED’s - Fast” + Beep:
Indicates charging at voltage that is higher than the
programmed value of High Voltage Threshold (14.8V (Preset)
/
15.3V
/
16V for 12V
battery and 29.6V (Preset)
/
30.6V
/
32.0V for 24V battery). The loop is: {Red » Yellow
» (Green + Beep) » All OFF}… repeats this sequential loop.
•
“Walking LED’s – Slow”:
Indicates charging at voltage higher than 13.3V (12V
battery)
/
26.6V (24V battery) but lower than the programmed value of High Voltage
The display pattern is “Walking LEDs – Fast” + Beep. In this pattern, the display / buzzer
loop is: {Red » Yellow » (Green + Beep) » All OFF}......Repeats this sequential loop.
NOTE:
The unit will not reset even after the battery voltage drops below the programmed
Over Voltage Threshold. This is helpful to know that an over voltage condition existed. The
alarm can be reset manually as follows:
•
Press and hold Programming Button » Beep will be heard » Release the Button
Low Voltage Alarm:
Following voltage thresholds can be programmed to warn
about low voltage condition (See programming procedure given separately).
•< 10.5 (Preset) or < programmed values of 10.6V / 10.7V / 10.8V / 10.9V / 11.0V
/11.1V / 11.2V
•< 21V (Preset) or < programmed values of 21.2V / 21.5V / 21.6V / 21.8V / 22.0V /
22.2V / 22.4V
When the programmed Low Voltage Threshold is reached, the following LED / Buzzer
pattern will be observed:
» (Red + Green) » (Orange + Beep)…….Repeats 10 times
» (Red + Green) » (Orange)….. Repeats 10 times
» All LEDs OFF. Unit enters Sleep Mode. There is a beep every minute so that it is clear that
the unit is not in a “3 Day Off Mode.”
NOTE:
The unit will reset only when the battery voltage rises to > 13.3V (for 12 V battery)
/ 26.6 V (for 24V battery) i.e. when charging takes place.
3-Day Timer:
A 3-Day Timer has been provided to automatically switch OFF the unit
after 3 days of switching ON of the Timer or if the battery voltage drops below 10.4V (for
12V battery) or 20.8V (for 24V battery). The Timer will be automatically switched OFF after
the battery voltage rises above 13,3V (for 12V battery) or 26.6V (for 24V battery).
ON / OFF Modes can be programmed as shown under heading “Programming
Alarm Thresholds / 3-Day Timer.”

OWNER'S MANUAL
Programming Procedure: Brightness of LED Display: The unit comes Specifications
preset with brightness of the LEDs set at Normal (Bright). The brightness can be dimmed or
the LEDs can be switched OFF. Settings can be changed with the help of the Programming
Button (5, Fig 1). Settings are performed in sequential order in a loop: Bright » Dim » OFF
» Bright » Dim » OFF… repeats the loop.
For changing the Setting: Press and hold Programming Button » Beep will be heard
» Release the Button.
Please note that when the LED display is switched OFF, the Buzzer alarm protocols stay
active in the background. Hence, if Under Voltage / Over Voltage condition is activated,
the LED display and Buzzer alarm protocols for the abnormal condition will be activated.
Programming Procedure: Alarm Thresholds / 3-Day Timer
Thresholds of Low Voltage
/
High Voltage Alarms and Timer ON
/
OFF settings are
programmed with the help ofProgramming Button (5, Fig 1) andby monitoring the LED
and Buzzer indication patterns.
CAUTION! Alarm thresholds are to be programmed
only when the voltage is between 10.5V and 13.3V (for 12V battery) and between
21V and 26.6V (for 24V battery). In this condition, the LEDs / Buzzer will not be
indicating (i) “charging” i.e., will not be displaying “Walking LEDs –Fast+Beep” or
“Walking LEDs –Slow” or (ii) "Low or High Voltage Alarm".
Programming Modes are SEQUENTIAL as shown in the sequence given below. This means
that in order to access programming of the desired parameter, it will be necessary to pass
through the previous programming positions. Press Programming Button (5, Fig 1) and
hold it in pressed condition. Release the Button ONLY when the LED + Beeping pattern for
the desired parameter is displayed.
The sequence starts with Programming Mode for Low Voltage Thresholds first followed by
High Voltage Thresholds and then followed by Timer ON/OFF. Before the start of each
ProgrammingMode,allthe3LEDsandbuzzerwillblinksimultaneously3times.
