Remote control and short circuit behavior
This section describes the behaviour of the Smart BatteryProtect when it is controlled via the remote on/off input and when a short circuit has been detected.
The Smart BatteryProtect will connect the load 1 second after the remote input is closed.
The Smart BatteryProtect will disconnect the load immediately when the remote input is opened.
When in Li-ion mode, the Smart BatteryProtect will observe a dead period of 30 seconds after the remote input of the Smart BatteryProtect has become free floating. See the note below for a detailed description.
In case of a short circuit, the Smart BatteryProtect will attempt to connect the load every 5 seconds. After two attempts the display will show E1 (short circuit detected).
Note
When in Li-ion mode, the SBP will disengage when the H input becomes free floating and will remain disengaged for 30 seconds, even if it receives a re-engage signal within that time period. After 30 seconds it will respond immediately to a re-engage signal. Therefore, there will normally be no waiting time if the SBP is used as a system on/off switch (wire the system on/off switch to the positive supply of the BMS for this purpose).
Similarly, if a system shutdown occurred due to low cell voltage, the SBP will remain disengaged for 30 seconds, even if it receives a re-engage signal within that time period (which most likely will happen when no other loads are connected to the battery). After 3 attempts to re-engage, the SBP will remain disengaged until battery voltage has increased to more than 13.0V (resp. 26.0V for a 24V system) for at least 30 seconds (which is a sign that the battery is being recharged). The under voltage thresholds and alarm output of the SBP are inactive in this mode.
