If a line fault occurs after the voltage has been connected to Line fault detection on On-button: S12, S31, S32, the unit will be activated because this line fault is similar The line fault detection is only active when S12 and S22 are switched to the normal On-function. simultaneously. If the On-button is closed before S12, S31, S32 is The unit can be operated with single channel and 2-channel operation connected to voltage (also when line fault across On-button), the output with cross fault monitoring.
