NOVATEK-ELECTRO LTD Intellectual Industrial Electronics RNPP-302 MULTIFUNCTIONAL THREE PHASE VOLTAGE MONITORING RELAY OPERATING MANUAL Quality control system on the production complies with requirements ISO 9001:2008 Review the Operating manual before using the unit. Store the unit in the operating environment for 2 hours before switching to the mains.
The RNPP-302 operates with the magnetic coil of the external contactor which in it’s turn operates with the power load. The RNPP-302 constantly checks (before and after turning on) the condition of the power contacts of magnetic contactor and detects the stuck together and burned contacts.
– “DOWN” Notes: 2. START UP PROCEDURE Connect the contactor (magnetic starter) to the RNPP-302 and make all other necessary connections as shown on Figure 2 Connect mains power supply to the input terminals of RNPP-302 Turn ON the power and adjust all required settings according to Table 2 NOTE.

4.2.4. Over/Under voltage monitoring (min/max) mode ( If the RNPP-302 was initially in turned OFF state then in case the correct voltage is applied to the device it parameter: the “REL” LED will light up and will automatically turn ON within the delay time defined by terminals 23, 24 will open while 22, 24 and 20, 21 will close.

- 6 - 4.4. Indication In the absence of the alarm situations on the LED display of RNPP-302 it shown the value of acting voltage (RMS voltage) on the selected phase marked by phase indicator (please see Figure 1). “REL” LED indicator shows the ON/OFF state of the output relays of RNPP-302. If “REL” LED lights that mean that the relay is turned ON.
