1-phase or 3-phase voltage monitoring relay (Multifunction) EMR IU11D Function description For all the functions the LEDs MIN and MAX are flashing alternating (the relay is fallen off), when the minimum value for the measured voltage was chosen to be greater than the maximum value. If a failure already exists when the device is activated, the output relay remain in off-position and the LED for the corresponding threshold is illuminated.
