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 (i.e. fuse blowing), 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 “over %” adjustment to maximum and the “under %” adjustment to minimum. Set 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 will close. Refer to the troubleshooting table if the unit fails to operate

correctly.

Set the “over %” and the “under %” adjustments to give the required monitoring range.

If large supply variations are anticipated, the adjustments should be set further from the nominal

voltage.

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

above or drop below the set trip levels. However, if during an under voltage condition the supply

drops below the 2

de-energises).
