The output is SPCO with an option of DPCO on either the din rail or 11 pin version.?Utilising transformer technology?the units are available in either 3 or 4 wire versions, the 4 wire version tripping on loss of the Neutral. On power up with all three phases present (plus the Neutral if applicable) and in the correct sequence the output relay will energise, the green and red LEDs also illuminate. On loss of a phase, (or Neutral 4 wire versions), drop in voltage below Umin levels, or incorrect phase sequencing the output relay/s after a fixed time delay of 0.5secs will drop out and the red LED will be extinguished. A green supply on LED only illuminated means that there is a supply to the unit but there is a supply fault or either a combination of; phase loss, under volts or sequence error. All terminal details and information along with the CE mark is clearly marked on the sides of the housing.
