Applying power.

Note:

This device is not suitable for applications where there could be a percentage of re-generative voltage

present during a fault condition, i.e. fuse failure. During these conditions a monitor that includes an

adjustable under voltage trip level is necessary which allows this type of fault to be detected. It is therefore

recommended that the M1prt or M1prt-4w phase monitors be considered.

Troubleshooting.

The table below shows the status of the unit during a fault condition.

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.

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.
