FEATURES
• Intelligently driven 160 A relay
• Motor status detection through vibration
• Low power consumption
• Simple installation
• Automatic 12 V/24 V system detection
PURPOSE
The BSWM160 (hereinafter: BSWM)is a high-
capacity mechanical switch with integrated vibration
(i.e. motion) detection that can be used in situations
where 2 batteries are present, for example, in
trucks, caravans and campervans.
For many modern vehicles it is no longer possible
to read whether a vehicle is switched ‘on’ by
measuring the battery voltage. The BSWM has a
sensor that detects vibrations. The BSWM can detect
whether a vehicle is on based on the measured
vibrations.
Since every vehicle is unique and has its own
vibration frequency and amplitude, the user can set
the sensitivity of the BSWM. The actions that must
be performed to set the sensitivity of the BSWM are
listed in the “Configure” section.
INSTALLATION
Connections
STATUS Start-Assist Input connection.
MINUS
Negative (–) connection. [
Note:
it must
always be connected through a 3 A fuse.]
CONFIG Input connection configuration.
A1
Main/start battery positive (+) terminal.
A2
Auxiliary battery positive (+) terminal.
Connection method
Step 1. The negative terminal (–) of the batteries
must be connected to connection MINUS of
the BSWM through a 3 A fuse.
Step 2. The positive terminal (+) of the main battery
must be connected to A1 of the BSWM.
Step 3. Connect the positive terminal (+) of the
auxiliary battery to connection A2 of the
BSWM.
Warnings:
• The product must only be connected by skilled
fitters/mechanics who are aware of the regulati-
ons for working with high battery voltages.
• Using inferior connection material and/or wiring
that is too thin may damage the product.
• A short circuit between the positive and negative
terminals of the battery may severely damage
your system.
• Always use fuses between the battery and the
BSWM.
OPERATION
The BSWM can operate in three different ways.
You can select a purely voltage-dependent control.
Another option is to select a system that reacts to
vibrations of the vehicle in which it can be found.
You can also select a combination of both systems.
Vibration detection [positions 4 to 17]
Using the internal vibration sensor, the BSWM can
detect whether a vehicle is switched ‘on’ or being
driven. As can be seen in the table below, the BSWM
operates purely on vibration detection in positions
4 to 17.
Voltage-dependent control [position 3]
The BSWM will be set as a voltage-dependent
control in position 3. The relay will be switched on
when starting up. If the voltage is below 11.8 V for
4 seconds, below 12.8 V for 60 seconds or below
16.0 V for 0.5 seconds, the relay will switch off.
If the relay is switched off, it will only switch on
again if it is below 15.8 V for 5 seconds (when it
detects overvoltage) or above 13.2 V for 7 seconds
(when it detects undervoltage).
Combination [positions 1 & 2]
In positions 1 and 2, the BSWM will switch based on
both vibration detection and detected changes in the
input voltage.
