USER MANUAL

User manual
The Voltage Guard is a vital part for a mobile installation. It
increases the battery live. It has low voltage, high voltage
and overload protection. Low voltage detection can easily
be adjusted by a rotation switch. This way any type of
(lead acid) battery can be protected against deep charge.
The over voltage protection protects your costly devices
against to high voltages.
The Voltage Guard can easily be used as a main switch.
This can be achieved by connecting a panel switch
between the ground (-) and the switch connection. The
main switch function cannot be used when this switch is
not connected. In this case the Voltage Guard operates as
a Voltage Guard only.
The status of the Voltage Guard is displayed by the three
color status led. A self test is done and the voltage of the
installation is detected when the battery is connected. In
this case the status led will flash in the following pattern:
red -> orange -> green. During this detection one beep will
be produced.
Explanation status led
Green: The battery voltage is ok. The output is switched
on.
Green flash: Four times a minute, optional panel switch
closed and the consumers are switched off.
Orange: The battery voltage is lower than the set point.
After 30 seconds the output will be switched off.
Red: The output is switched off. The cause can be: low
voltage, high voltage or overload.
Explanation alarm situations
Low voltage
The status led is lid orange if the battery voltage is lower
than the set point. Does the voltage stay lower than the set
point for over 30 seconds, the output will switch off. The
status led is lit red. Once in 10 seconds a three tone
acoustic signal with a long interval is generated. The
output will be switched on when the battery is charged and
reaches undervoltagesetting+1,5V at 12V and
undervoltagesetting+3V at 24V. This can also be done by
switching the optional panel switch off an on.
High voltage
The output will switch off when the battery voltage is
higher than 15,5V / 31V, the led is lit red. Once in 10
seconds a three tone acoustic signal with a medium
interval is generated.
Overload
The output will switch off when the Voltage Guard is
overloaded for a long time. The status led is lid red and
once in 10 seconds a three tone acoustic signal with a
short interval is generated. The housing can be warm.
The output will switch on when the housing is cooled
down.
Low voltage setting
The low voltage setting can be adjusted by the rotate
switch. The numbers are corresponding with the table on
the front of the Voltage Guard. Adjusting can be done with
a small screwdriver. The low voltage protection can be
switched off by selecting the ‘0’, ‘8’ or ‘9’ position. In this
way the battery can be discharged further.
Voltage Guard as main switch
If a panel switch is connected the main switch function can
be used. The output is turned off when the switch is
closed. The status led is off and flashes green four times a
minute.
The normal Voltage Guard function is activated when the
switch is opened. Normally in this case the status led is lid
green and the output is switched on but this is depending
on de status of the battery and Voltage Guard self.

INSTALLATION
EN / WBI-VG 200 / February 2012 3
Installation
Install the Voltage Guard on a solid surface. Use reliable
terminals to avoid bad connections. Fasten the bolts tightly
but not overtighten them. Connect the Voltage Guard
according the wiring diagram as shown below. Connect
the ground terminal via a ‘faston’ connector with the
ground of the installation. Make the connection between
the terminal and the + of the system. Connect the
consumers to the terminal.
Make sure the wiring has the appropriate size and the
is fused with the right value!!!
Make the next connections when the main switch function
will be used. Connect one side of the switch contact to the
switch connection on the Voltage Guard. And connect the
other side to the ground (-) of the installation.
Safety measures
Use wiring with the appropriate size. Use the right fuse in
wiring.
Mount the Voltage Guard in a dry and ventilated place.
Never use the Voltage Guard at locations where there is
danger of gas or (dust)explosion.
Make the connections and protections according the
locally applicable regulations.
Check once a year the wiring and connections and repair
the faults.
The manufacturer can not be held responsible for damage
resulting from the use of the Voltage Guard.
