START/PROTECT Operation

The controller can operate in two modes: Start and Protect.
In Start, the 2 output channels can provide all the output power
regardless of the pump condition up to the short circuit condition.
This operating mode must be used to start the pump at high pressure.
In Protect, the controller limits the output current and switches off
the HV when the current exceeds the threshold value (8 mA for 40 W
channel and 16 mA for 80 W channel) for more than 2 seconds.
