1. APPLICATION
Single phase (220V/50Hz) voltage monitoring relay RN-111M (hereinafter RN-111M) is designed
to turn OFF home used consumer equipment or industrial power load in case of unallowable voltage
fluctuations. And when the voltage parameters returned back to normal values after fluctuation – it
should automatically turn ON the power load with the user adjusted time delay.
1●If power load is less than 3,5 kW (16A) then RN-111M may operate with the power load by
its own output terminals;
2●If power load is more than 3,5 kW (16A) then it should be commutated using contactor of
appropriate power rating. So RN-111M operates with the magnetic coil of the contactor and thus
turns ON/OFF the power load when necessary. Kindly note that contactors of appropriate power
rating should be chosen by User and not supplied along with RN-111M.
RN-111M has four independent modes of operation:
11.Minimal/Maximal voltage protection relay;
22.Minimal voltage protection relay;
33.Maximal voltage protection relay;
44.TurnON time delay relay.
On the LED digital display RN-111M indicates the value of acting voltage level and the
Open/Close (ON/OFF) state of the output terminals.

3. GENERAL DESCRIPTION AND OPERATION
RN-111M has several functional states:
– Normal operation mode: Power load is ON, Green LED indicator – ON. Digital LED display
shows measured voltage value;
– Alarm mode: Power load is OFF, Green LED indicator – OFF. Digital LED display shows
blinking value of the measured voltage;
– Indication of the remaining time to turn ON the power load (Ton): Power load is OFF, Green
LED indicator – OFF. Digital LED display shows the remaining time to turn ON the power load (in
seconds) and dot is being displayed in the lower digit. After the Ton time elapse RN-111M will return
to Normal operation mode if voltage parameters on the input terminals are within the permitted
range adjusted by the user.
User may select four independent operation modes:
3.1. Minimal/Maximal voltage protection relay
This mode is active when both toggle switches (Umin, Umax) are set to the Left position. In case
the voltage level will get lower/higher than the user adjusted allowable values – the power load will
be turned OFF. RN-111M will turn ON the power load with the user preset time delay (Ton) only after
voltage parameters returned back to normal.
Power load (contactor coil) should be connected to the output terminals 3(4), 6.

If RN-111M was initially deenergized or the power load was OFF due to the wrong voltage para-
meters – then after correct voltage appear on the input terminals and after the time delay Ton con-
tacts 1,3(4) will open and contacts 3(4),6will close.
If input voltage get lower than minimal voltage threshold for more than 12 seconds RN-111M be-
comes to Alarm mode – contacts 1,3(4) close and contacts 3(4), 6open and thus the power load
should be turned OFF.
If input voltage gets 60V lower than the minimal voltage tripping threshold – RN-111M turns OFF
the power load within 0,1 sec (accelerated tripping time). After the recovery of the voltage parameters
to the value of hysteresis (4-5V) – RN-111M turns ON the power load with the user adjusted time
delay Ton.
If input voltage gets higher than the maximal tripping voltage threshold for more than 1 s or
accelerated tripping time of 0,1 sec is applied if the voltage is 30V higher than the maximal tripping
threshold – then the RN-111M comes to Alarm mode – contacts 3(4), 6open and contacts 1,3(6)
close. When voltage level decrease lower than the maximal tripping voltage threshold to the hyste-
resis value (4-5V) – RN-111M turns ON the power load with the user adjusted time delay Ton.
3.2. Minimal voltage protection relay
This mode is active when toggle switch Umin is set to the Left position and Umax is set to the right
position. RN-111M will turn OFF the power load if voltage level will get lower than the Minimal voltage
threshold preset buy the user (Figure 1; item - 4).
Power load (contactor coil) should be connected to the output terminals 3(4), 6.
If RN-111M was initially deenergized or the power load was OFF due to the wrong voltage para-
meters – then after correct voltage appear on the input terminals and after the time delay Ton con-
tacts 1,3(4) will open and contacts 3(4),6will close.
If input voltage get lower than minimal voltage threshold for more than 12 seconds RN-111M be-
comes to Alarm mode – contacts 1,3(4) close and contacts 3(4), 6open and thus the power load
should be turned OFF.
If input voltage gets 60V lower than the minimal voltage tripping threshold – RN-111M turns OFF
the power load within 0,1 sec (accelerated tripping time). After the recovery of the voltage parameters
to the value of hysteresis (4-5V) – RN-111M turns ON the power load with the user adjusted time
delay Ton.
3.3. Maximal voltage protection relay
This mode is active when toggle switch Umax is set to the Left position and Umin is set to the right
position. RN-111M will turn OFF the power load if voltage level will get higher than the Maximal vol-
tage threshold preset buy the user (Figure 1; item - 3).
Power load (contactor coil) should be connected to the output terminals 1, 3(4).
When normal voltage applied to the input terminals of RN-111M – the state of the output relay
doesn’t change so the RN-111M stay in the “cold” state: contacts 1,3(4) are closed and contacts
3(4),6are opened.
If input voltage gets higher than the maximal tripping voltage threshold for more than 1 s or
accelerated tripping time of 0,1 s is applied if the voltage is 30V higher than the maximal tripping
threshold – then the RN-111M comes to Alarm mode – contacts 1, 3(4) open and contacts 3(4),6
close. When voltage level decrease lower than the maximal tripping voltage threshold to the
hysteresis value (4-5V) – RN-111M turns ON the power load with the user adjusted time delay Ton.
3.4. Turn ON time delay relay
This mode is active when both toggle switches (Umin, Umax) are set to the Right position. In this
mode voltage parameters are not controlled and RN-111M will turn ON the power load with the user
preset time delay (Ton) if the input voltage parameters are within the operation voltage range.
Power load (contactor coil) should be connected to the output terminals 3(4), 6.
If the input voltage is more than 160V RN-111M will turn ON the power load after the delay time
will finish. If the voltage will get lower than 120V RN-111M will go to Alarm mode – contacts 1,3(4)
close and contacts 3(4), 6open and thus the power load should be turned OFF.
ATTENTION!!! At first start-up or after the RN-111M was completely deenergized additional time

delay of 0,3-0,4 second is required for self testing. During this time LED display indicates “StA” and
then start showing the remaining time to turn ON the power load.
Thus turn ON time will be 0,3 s + Ton time.
If RN-111M is being used as maximal voltage protection relay – then no time delay for the first
start-up.
ATTENTION!!! ALL CONNECTIONS MUST BE DONE ONLY ON DEENERGIZED RN-111M
AND ACCORDING ALL SAFETY REGULATIONS
4. START-UP PROCEDURE AND CONNECTION
Using toggle switches on the front panel set necessary mode of operation (see Section 3);
In case of using RN-111M as Minimal/Maximal protection relay or Minimal protection relay connect
wires according the Wiring Diagram (see below). If RN-111M is being used as a maximal voltage
protection relay power load (contactor coil) should be connected to terminals 1and 3(4).
If power load is less than 16A (3,5 kW) then it could be commutated directly by the output contacts
of the RN-111M; if the power load is more than 16A – then it should be commutated using contactor
of appropriate rated parameters and the RN-111M should operate with the magnetic coil of the
contactor.
Connect RN-111M to the power circuit. For easier wiring purposes there are coupled input terminal
contacts 7-8 and 11-12.
By spinning the knobs on the front panel set the required Minimal and Maximal voltage tripping
thresholds (Umin and Umax) and set necessary turn ON time delay (Ton). Please pay attention that
the Ton time should be adjusted taking into consideration the technical documentation and require-
ments of the protected power load – for example – air-conditioners, refrigerators and other compres-
sor containing equipment usually need 3-4 minutes pause before turn ON again after they were
disconnected.
Give the power supply to the input terminals of the RN-111M and by spinning the adjustment knobs
set precisely the required values for the Umin, Umax and Ton. When spinning the knobs on the LED
digital display it is shown the exact value of the adjusted parameter.
