DinPSF1 : Phase Failure




Applying power to the controller illuminates the Green LED.

Providing that all 3 phases are connected & the phase to phase voltages are within the specified parameters, the Red LED illuminates, the unit relay energises & the state of the contacts changes.

Should the imbalance (voltage difference) between any of the phases be +/-15% of the supply voltage, the Red LED will go out, the relay will de-energise & the contacts will change state.
