FUNCTION DIAGRAM

INSTALLATION AND SETTING

BEFORE INSTALLATION, ISOLATE THE SUPPLY.

Connect the unit as required. The diagram below shows a typical installation, whereby the supply to

the load is being monitored by the relay. If a fault should occur, the contactor is de-energised

removing the 3-phase supply to the load. The contactor only re-energises after the fault has cleared.

Set the “trip level” and the “time delay” to minimum.

Apply power and the green “supply on” and red “relay” LED’s will illuminate, the relay will energise

and contacts 15 and 18 / 25 and 28 will close. Refer to troubleshooting table if the unit fails to operate

correctly.

Accurate setting can be achieved by adjusting the “trip level” until the unit trips (relay de-energises)

then by decreasing the “trip level” setting until the relay re-energises. By close setting of the “trip

level”, the unit will also detect a phase loss even with a large percentage of re-generative voltage.

In order to set the unit as previously described but without causing disruption to the equipment being

controlled/monitored, set the “time delay” to maximum. It will now be possible to establish the trip

point when the red “relay” LED starts to flash. Decrease the trip level setting to stop the LED flashing.

(Note: If the time delay is allowed to expire, the output relay will de-energise).

If large supply variations are anticipated, the “trip level” should be set further from the nominal

voltage.

Set the “time delay” as required. (Note that the delay is only effective should the supply drop below

the set “trip level”. However, if during an under voltage condition the supply drops below the 2

under voltage trip level, any set time delay is automatically cancelled and the relay de-energises).
