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 (use the System on/off switch in the positive supply of the BMS for this
purpose).
Similarly, if a system shut down 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 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 52V during 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.
To manually make it start again, briefly disconnect and reconnect the remote on/off terminal or switch the BMS off and on again.
(Remote H terminal, can be connected to battery plus to turn on)
(Remote L terminal, can be connected to battery minus to turn on)
