BEFORE INSTALLATION, ISOLATE THE SUPPLY.

Connect the unit as required. The Connection Diagram below shows a typical installation, whereby

the supply to a load is being monitored by the Phase monitoring relay. If a fault should occur (i.e. fuse

blowing), the relay will de-energise and assuming control of the external Contactor, de-energise the

Contactor as well.

Set the “Over %”

the “Delay (t)”

Apply power and the green “Power supply”

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 “Delay (t)” adjustment 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

the relay de-energises).

Note: If the supply voltage increases above the maximum “Over %” trip setting by approx. 5% or

more, the relay will de-energise immediately.
