Delay
Check if the input range is correct. Turn the power ON. The green LED is ON. Adjust the delay, upper ( ) and lower ( ) level knobs to the desired value.
Provided that all the 3 phases are present in the proper sequence, as long as they are all within upper and lower set points, relay and yellow LED are
ON. When one or more phase exceeds the upper level or drops below the lower level for more than the set delay time relay and yellow LED turn OFF,
red LED (flashing 2 Hz during the delay time) turns ON. If the phase sequence is wrong or one phase is lost the output relay releases immediately (only
200 ms delay occurs). This failure is indicated by the red LED which flashes 5 Hz as long as the alarm condition is occurring.

To access the DIP switches open the plastic cover using a screwdriver as shown on the left.
Select the input voltage range by setting DIP switches 3 and 4 for M23 and M48 versions, DIP switches 3, 4 and 5 for M44 only. Select the desired
function by setting DIP switches 1 and 2. Use DIP switch 1 to set a power ON delay. The actual mains reading will start after this set delay, thus alarms
are inhibited during the delay. DIP Switch 2 sets the mains as either 3Ph (Delta) or 3Ph + N (Star).
Do not open the DIP switches cover if the power supply is ON

Connect the 3-phase power supply and the neutral (if present) taking care of the sequence (N ver-
sions don’t detect incorrect phase sequence). Connect the relay output according to the ratings.
Keep power OFF while connecting!
