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

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 the voltage of 7 to 32V is seen on the connection of the battery. At startup, Red LED is activated as a sign of power-up. After some time, the unit is initialized and the 12V / 24V battery is recognized. The State of Charge is displayed thereafter.

LED and Buzzer Indications for Voltage Levels:
*NOTE: The term “Walking LEDs” has been used to indicate cyclical, sequential lighting patterns of Red, Yellow, and Green LEDs. This pattern indicates that charging is taking place. The 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 a voltage higher than 13.3V (12V battery) / 26.6V (24V battery) but lower 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» All OFF)… repeats this sequential loop.

Status of LEDs and Buzzer| Battery Voltage indicated for 12V
Battery| Battery Voltage indicated for 24V Battery
---|---|---
Walking LED’s – Fast + Beep (Indicates charging in progress and the voltage is higher than the programmed threshold of Over Voltage Alarm)| > 14.8 (Preset) /
15.3V / 16.0V| > 29.6V (Preset) /
30.6V / 32.0V
Walking LED’s – Slow (Indicates charging in progress under normal conditions)| > 13.3 But <(14.8V
(Preset) / 15.3V /
16.0V)| > 26.6V But < (29.6V
(Preset) / 30.6V /
32.0V)
Green| > 12.4| > 25.0V
Green+Yellow| > 11.6| > 23.2V
Yellow| > 11.2| > 22.2V
Yellow+Red| > 10.9| > 21.8V
Red| > 10.5| >21.4V
(Green +Yellow + Red) – Blinking| –| > 21V
The following pattern indicates voltage is below the programmed threshold for the Low Voltage Alarm:
(Red + Green) » (Yellow + Beep)… repeat 10 times
» (Red + Green) » (Yellow)… repeats 10 times
» All LEDs OFF. Unit enters
Sleep Mode. There is a beep every min.| < 10.5 (Preset) or < programmed values of 10.6V / 10.7V / 10.8V /10.9V/11.0V /11.1V/11.2V /21.6V/21.8V| < 21 V (Preset) or < programmed values
of 21.2V / 21.5V / 22.0V / 22.2V / 22.4V

High Voltage Alarm during Charging:
Following voltage thresholds can be programmed to warn about overvoltage conditions during charging (See programming procedure given separately).

14.8V (Preset) / 15.3V / 16V for 12V battery
29.6V (Preset) / 30.6V / 32.0V for 24V battery

This facility can be used to indicate the onset of the “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.
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 overvoltage condition existed. The alarm can be reset manually as follows: · Press and hold the Programming Button » Beep will be heard » Release the Button
Low Voltage Alarm: Following voltage, thresholds can be programmed to warn
about low voltage conditions (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. The 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 the heading “Programming Alarm Thresholds / 3-Day Timer.”
Programming Procedure: Brightness of LED Display:
The unit comes preset with the 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 the 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 the 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 of the Programming Button (5, Fig 1) and by 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 the 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 Programming Mode, all the 3 LEDs and buzzers will blink simultaneously 3 times.
To START, press the 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.
