NOVATEK-ELECTRO
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. During the countdown of the autoreclosing time delay LED indicator REL will blink in
case of the normal power parameters. Time countdown of the autoreclosing delay starts from the moment of the
fault detection (not from the moment when the power parameters recovered to their corresponding rated values).
In case the power interruptions in minimal voltage, maximal voltage, phase loss and phase imbalance the
corresponding LED will light up to mark the phase where the interruption happened.
If the wrong phase sequence was detected by RNPP-30
2
all red LEDs will light up in turns.
On all other alarm situations all red LEDs will light permanently.
All codes of the alarm situation are shown on the LED display according to the
Table 1
.
4.5. Signalization
Signalization relay output turns ON/OFF simultaneously with the main output relay that operates with the
power load. This allows to use signalization relay for the operation by the contactor also. So the main output
relay could be used as a signalization relay with normally closed contacts (contacts are closed when there is
no alarm situation).

0 - PHASE LOSS RELAY (minimal and maximal
voltage are not controlled), RNPP-302 turns OFF
the power load only if voltage disappear on 1 or
2 phases;
1 - MINIMAL VOLTAGE RELAY, RNPP-302 turns
OFF the power load if the voltage gets lower
than preset
value;
