Read the owners manual carefully before installing the BG!
Description
The Battery Guard BG40/60/100/200 (hereafter BG) is an intelligent, fully waterproof, battery guard with expansion capabilities for an on/off switch, alarm
buzzer or relay and our Battery Watch (not supplied). To ensure low losses, the BG is provided with two screw terminals, one Input+ and one . The
rest, like the minus and the accessories are connected via four 6.3 mm faston connectors. The LED indicates the output status (on/off) of the BG and in the
programming mode the LED indicates the program position. The BG is provided with an 'Automatic board system detection' with which the BG automatically
detects what the battery voltage (12V or 24V) of the system is, so that it does not need to be set manually. Both under and over voltage thresholds can be
easily programmed.
Installation
Mount the BG on a cooling (metal) surface so that it can release the developed heat. Connect the BG as close as possible to the battery (maximum distance:
50cm). Only in this way can the voltage be monitored exactly. Any programming of the BG must take place before the equipment (users) can be connected. For
the minus connection use a cable of 1.5 mm2 which goes directly from the battery to the BG and do
not
use this connection for anything else.
Warnings:
The product should only be connected by skilled fitters / mechanics, who are aware of the regulations for working with high battery voltages.
Live parts must not come into contact with the housing of the BG.
Use of bad material and / or too thin wires can damage the BG.
A short circuit between the positive and negative terminals of the battery may cause severe damage to your system.
Always use fuses (of the correct value).
Operation
In the standard programming (position 11 in the "Configuration Table") a buzzer may be connected to the alarm output. This will sound an alarm after 15
seconds when there is undervoltage. If the situation does not change, the BG will turn off attached devices after 60 seconds and the alarm will be switched off.
Since with overvoltage there is a risk of damage to the connected equipment this will be switched off immediately when there is overvoltage (16/32V) and the
alarm output will pulsate. This is done to distinguish between an undervoltage alarm and an overvoltage alarm.
A second application is to connect a relay to the alarm output. The BG must then be programmed in position 12 (see “Programming”). The relay will switch on
during an alarm and only switch off when reaching the reset value of the undervoltage. The relay can thus be used to activate a charger or generator.
Remote ON / OFF
You can connect a switch to the OFF terminal of the BG. If the OFF terminal is connected to the Minus the BG will immediately switch off the attached devices.
If the switch is opened again, the BG will switch on again after about 5 seconds. Since the current through the switch is zero (<10mA) a small switch can be
used.
Battery Watch (optional)
As can be seen in the connection diagram, there may be an optional Battery Watch connected. This is a simple battery status monitor which, by means of 3
LEDs, indicates the status of the battery. Please contact your dealer.
Programming
Configuration Table
To start the programming mode a connection must be made
between the ProgramInput and Input+. The LED will flash. The
number of flashes indicates the program position (see table) that
the BG is in. As soon as the desired program position is reached
the connection (between the ProgramInput and the Input+) must
be broken. As confirmation the BG will repeat the number of
flashes. If it does not match your selection, you can repeat the
steps.
There are two types of settings that can be applied. Positions 1 to
10 adjust the threshold and reset values for ??an under voltage
alarm and the operation of the alarm can be set with positions 11
and 12. These settings must be made separately (one after
another).
When removing the battery voltage the programmed positions
remain retained. Once the programming is complete, the
equipment can be connected. First disconnect the battery
connection, connect the equipment to the and then
reconnect the battery.
Note:
Before programming first disconnect the equipment from
the BG.
