The automatic float stage is beneficial for systems that transmit
occasionally as it keeps batteries topped off for extended periods of time without risk of overcharging.
Self-Diagnostic to detect critical faults
The SS Generation 3 includes a multi-color status
LED as well as 3 Battery LED’s. Together these
can indicate up to 13 possible error conditions.
When the controller is functioning properly it is
clearly indicated by the status LED as green.
All faults are electronic and reset
automatically when resolved.

internal fuses)
