PUVR44-2-A.DOCX XXXXX Dims: to DIN 43880 W. 44mm INSTALLATION AND SETTING

• 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. Setting the unit and applying power.
• Set the “Nominal Voltage (Un)” ➌ voltage adjustment to match that of the supply voltage being monitored.
• Set the “Trip Level” ➎ and “Differential” ➏ adjustments to minimum. Set the “Time Delay” ➍ to minimum.
• Apply power and the green “Power supply” ➊ LED will illuminate and relay will energise after the short Power on delay (Td). The red “UNDER” LED ➋ will remain extinguished.
• Refer to the troubleshooting table if the unit fails to operate correctly. Setting the unit (with power applied).
• Accurate setting can be achieved by adjusting the “Trip Level” until the unit trips (relay de-energises/red LED lit) then by decreasing the “Trip Level” until the relay re-energises again (red LED extinguished). Close setting of the trip level ensures the unit will 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 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 “Delay (t)” 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 fixed “Uoff ” trip level any set time delay is automatically cancelled and the relay de-energises). Testing on single phase
• For the purpose of testing/checking the unit where 3-phase is not available, wire the unit as shown in the diagram on the right. The procedure further up (Setting the unit and applying power) still applies. Troubleshooting. The table below shows the status of the unit during a particular fault condition.
