Start generator upon sensing low battery voltage and shutdown on high voltage.
Auto start modules
User Manual (PDF file)
This Battery Voltage Sensor (BVS) is designed to control the
battery bank voltage up to 99.9Vdc by automatically starting, running and
shutting down the auto start enabled generator (or engine).
How it works
Upon sensing the low voltage threshold, the BVS will close
the internal relay contacts (COM and NO) which gives a start signal to the auto
start enabled generator. The generator will be running and charging the battery
bank until the high voltage threshold detected. When BVS detects the high
voltage threshold the internal relay contacts (COM and NO) will open and the
generator stops.
The same procedure will repeat once the low voltage
threshold detected.
To set up this BVS controller to act as described above
please use the following settings:
- Select the working mode: "P2" (as per user manual
instructions) and select the "ON L" relay mode. Connect your auto
start enabled generator inputs to the BVS controller "COM" and
"NO" terminals.
- Connect the power supply (the engine starting battery) to
"GND" -negative terminal and "Power+" positive terminal.
- Connect your controlled battery bank negative wire to
"GND" and positive wire to "Volt+"
Important note!
It is possible to feed the controller from the same source the
BVS is monitoring to if the battery working voltage is not higher than 60Vdc.
In this case it is possible to link the "Power+" and
"Volt+" terminals together.
However, if the controlled battery working voltage is higher
than 60Vdc please feed the BVS controller from the separate battery (such as
the engine starting battery 12Vdc) connected to "GND" and “Power+"
terminals. The controlled battery bank is connected to "GND" and
"Volt+" terminals in this case.
