DIP switch
To install the device, proceed as follows:
1. Disconnect the battery from the vehicle power circuit.
WARNING!
Disconnect the negative cable first.
2. Set the desired switch-off voltage on the DIP switches
(10)
.
3. Connect an earth wire from the battery monitor’s ground
(6)
con-
nector to the battery's negative terminal.
NOTE!
Only the switching current (1 A) is permissible. The con-
sumer load must not lead via the 'ground’ connector (6).
4. Disconnect the positive lead from the battery to the consumers
and connect the battery monitor at the screw terminals
(1)
and
(2)
.
5. Connect the battery to the vehicle power circuit.
ð
The device is ready for operation. When the battery voltage is
sufficient, the operating display
(3)
lights green.
Optional connections
– Connect an external buzzer via the ‘alarm output’ connector
(5).
NOTE!
Contact to ground, max. 1 A.
– Use the battery monitor as a main switch for connected con-
sumers by running a line with a switch between the negative
terminal of the battery and the connector for “external
switch”
(4)
.
– Connect the 3-colour LED by connecting the anode for green
(shortest leg) to the “Green” LED connector
(7)
, the cathode
(longest leg) to the LED connector
(8)
and the anode for red to
the “Red” LED connector
(9)
.
Operating status
Indicator
Operating status
LED lit green
Alarm output inactive
Internal buzzer off
Battery voltage is above the alarm
threshold setting, device is active.
LED flashes green
Alarm output inactive
External switch
(4)
is closed, consumers
are switched off.
Indicator
Operating status
Internal buzzer off
LED lit orange
Alarm output active
Internal buzzer beeps at
interval
*
Safety level 1
: Below alarm threshold.
Battery voltage will soon reach the
switch-off voltage.
1. Switch the consumers off or charge
the battery
LED flashes red
Alarm output inactive
Internal buzzer beeps 1x
Safety level 2:
Below switch-off
voltage. Consumers have been discon-
nected from the battery to avoid deep
discharge.
2. To supply consumers again, charge
the battery to the switch-on voltage.
LED no colour
Device is switched off or incorrectly in-
stalled.
*
Internal buzzer interval: 600 s – 300 s – 150 s – 75 s – 37 s – 18 s
– 9 s.
After that: Internal buzzer beeps every 9 seconds until the switch-
off voltage is reached.
NOTE!
The operating status of the device is shown by the operat-
ing display (3), the 3-colour LED, the alarm output (5) and the in-
ternal buzzer.
Decommissioning
To decommission the device, proceed as follows:
1. Disconnect the battery from the vehicle power circuit.
WARNING!
Disconnect the negative cable first.
2. Remove the leads on the connectors
(1), (2), (4), (5)
and
(6)
from the vehicle.
ð
The device is decommissioned.
Disposal
Dispose of the device in accordance with the Waste
Electrical and Electronic Equipment Regulations
(WEEE).
The system must not be disposed of with household
waste. Take it to a recycling point or return it to your
point of sale.
