Please see the image below for the control wire connection locations.
Connection 1 is the main On/Off control input and can only be used when DIP switch 4 is set
to off. This input can be used to enable or disable the charger and is ‘active high’. When a
voltage higher than 2V is applied to this input, the charger turns on. When a voltage lower
than 1V is applied, the charger turns off and draws zero current. The maximum input voltage
is 32V. In a vehicle application is it recommended to connect this input to the engine run
signal. Contact your vehicle distributor to find out the most suitable connection.
BMS input connection 2 can be used to force the charger in standby mode. In this mode the
charger stops charging, but the internal circuits stay active to immediately resume charging
once allowed again. This input can be used to connect to a Lithium battery BMS in order to
stop the charging process if required. By default this input is ‘active low’ (< 1V is On and
> 3V is Stand by), but this can be changed to ‘active high’ as well by the Samlex Dashboard
or Dashboard Mobile app. The maximum input voltage is 32V.
Connection 3 is an open collector output that can be used to for example connect to a remote
indicator light. The maximum switching voltage and current are respectively 32V and 150mA.
By default this output is active (low) when the charger is charging or when charging is finished.
Other active conditions can be selected in the Samlex Dashboard or Dashboard Mobile apps.
Connection 4 is reserved for future use and has no active functionality yet.
