Operating Instructions
With the incoming isolator closed the unit will monitor the incoming
supply. If no fault condition is present approximately 1 second after
closing the incoming isolator the O-PEN monitor will energise the
under-voltage release mechanism of the 5 pole isolator (indicated by
the green LED illuminating). At this point the 5 pole isolator can be
closed to connect the load to the incoming supply. Alternatively wait
30 seconds and the isolator will automatically close.
In the event the O-PEN unit detects a fault condition on the monitored
supply for a period of 4 seconds the internal relays will de-energise and
remove the supply to the under-voltage release mechanism of the 5
pole isolator. This will cause the 5 pole isolator to open disconnecting
all phases, neutral and CPC from the load.
Once the fault condition has cleared the O-PEN unit will reset after a 3
minute period and the 5 pole isolator will automatically reclose 30
seconds after.
Test Function
A Test Switch is provided to allow the functionality of the
units to be checked. With the unit powered and the 5 pole
isolator closed rotate the Test Switch anti-clockwise to
position O to initiate a test. This will disconnect L1 from the O-PEN
monitor and create a fault condition. After 0.7 seconds the O-PEN
monitor will trip the 5 pole isolator by de-energising the under-voltage
release mechanism.
Return the Test Switch to position I to clear the fault condition.
The O-PEN unit will reset after 3 minutes.
We recommend the unit is tested on a 6 monthly basis.
