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
Motor status detection through vibration
trucks, caravans and campervans.
●
Automatic 12 V/24 V system detection
●
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.

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/mecha-

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.
Undervoltage and overvoltage
Regardless of the position in which the BSWM has been configured,
the BSWM will always switch off if the voltage is under 11.6 V or
above 17.0 V for a short period. The BSWM will again be reset if
the voltage again falls within the range of 11.8 and 16.8 V during
5 seconds.
Start-Assist
Regardless of the setting the BSWM has been configured to, it will
always switch on if a voltage is set on the Start-Assist pin. The
relay will continue to be switched on as long as there is voltage
on the pin. The BSWM will always switch off 30 seconds after the
voltage has been removed from this pin. After which, the BSWM will
operate as if it has just been connected.
