NOVATEK-ELECTRO RNPP-311M
Notes:
1) If on the first start up RNPP-311M
doesn’t allow to turn ON the power
load and indicates wrong phase
sequence alarm but the user is
absolutely sure that the phase
sequence is correct –then it is
necessary to exchange the wires
connected to terminals 10 and 11.
2) If RNPP-311M is being used as a
maximal voltage protection relay
then the break in the magnetic starter
coil power circuit should be connected
to terminals 1-2 (4-5) (the reverse logic
of switching-on).
The switch Umax (it. 6, Fig. 1) should
be set to ON position (enabled) and
the switches SEQ, IMB and Umin
should be set to the OFF position
(disabled).
Figure 2 - RNPP-311MConnection diagram
3.1.2.2. Using the Unom ±% control (it. 12, Fig. 1), set the required operation threshold for the maximum
and minimum voltage as a percentage of the rated supply voltage of the mains.
Attention! When setting the lower threshold for Umin, the release voltage of the MS must be taken
into account.
3.1.2.3. Using the Toff (sec) control (it. 10, Fig. 1), set the protection operation time at the maximum
voltage and phase imbalance.
3.1.2.4. Using Ton(sec) control (it. 11, Fig. 1) set the reclosing time AR.
Ton(sec) is the time of automatic reclosing after the device operation and restoration of the mains voltage
parameters; on-time is after the rated voltage supply to the device.
It is recommended to set the reclosing time AR for air conditioners, refrigerators and other compressor
equipment at least 180 - 240 seconds.
ATTENTION! In order not to break or turn the control, please do not use excessive force when
performing the setting operations.
3.1.2.5. Enable the necessary protections using protection switches (it. 3 –6, Fig. 1).
3.1.2.6. Set the type of mains used with switch of rated voltage of 400 V / 415 V (it. 2, Fig. 1).
3.1.2.7. Feed the supply voltage to the terminals of the device.
3.2. Operation
3.2.1. It is possible to adjust the RNPP-311M to operate in following modes:
–“Minimum / maximum voltage control";
–“Minimum voltage control";
–“Maximum voltage control";
–"Phases presence control";
–"Control of incorrect phase sequence and presence of phase sticking";
–"Phase imbalance control".
NOTE: The control of the phase presence is kept in any operating mode.
In “Minimum / maximum voltage control" mode, when the voltage value of the mains is exceeded for the
thresholds set by the User, the protected equipment will be disconnected from the mains and red ALARM
LED indicator will turn ON .

- 6 -
RNPP-311M NOVATEK-ELECTRO
In “Minimum voltage control" mode, when the mains voltage drops below the threshold set by the User,
the protected equipment is disconnected from the mains and red ALARM LED indicator will turn ON.
In “Maximum voltage control" mode, when the mains voltage rises above the threshold set by the User,
the protected equipment is disconnected from the mains and red ALARM LED indicator will turn ON.
In "Phases presence control" mode, if one phase is broken, when one of the LINE LED indicators will turn
OFF, the protected equipment is disconnected from the mains. Red ALARM LED indicator will turn ON.
In "Control of incorrect phase sequence and presence of phase sticking" mode, if the connection is
incorrect or if one of the phases is sticking, one of the LINE LED indicators lights up on the front panel of the
device, the ALARM LED indicator will turn ON and the protected equipment disconnects from the mains.
In "Phase imbalance control" mode, in case of voltage imbalance, two LINE LED indicators flash
alternately on the front panel of the device, the ALARM LED indicator will turn ON and the protected
equipment disconnects from the mains.
3.2.2. The device at the output has two groups of independent output changeover contacts (1-2-3, 4-5-6).
If there is no voltage to the device, the contacts 1-2 (4-5) are closed, and the contacts 2-3 (5-6) are open.
When the RNPP-311M is operated, the load is disconnected by interrupting the power supply of the MS
coil through 1-2 (4-5) contacts, except for the "Maximum Voltage Control" mode in which the device is
operated with an inverse switching logic.
3.2.3. After the power is supplied to the terminals of the device, the indicators LINE turn ON. The device
goes into the AR delay time mode (set by the Ton(sec) control),while the ALARM indicator flashes. After the
reclosing time has finished, the ALARM indicator turns OFF and the device connects the protected
equipment to the mains.
In the event of the failure, the reclosing time AR begins immediately after the device disconnects the
protected equipment.
3.2.4. If the device is used in the “Maximum voltage control" mode, at normal voltage in the mains, the
device contacts 1-2 (4-5) are closed, and the contacts 2-3 (5-6) are open. This is done to ensure that the
device in the "Maximum voltage control" mode has never operated for reducing the voltage. In this mode,
when the device is turned on for the first time, the reclosing time value (Ton(sec)) is not taken into account.
Note: in all modes of operation RNPP-311M trips the power load with the fixed time of 0,2 sec in case of
phase loss or if the voltage on any of the phases get lower than 100V.
