3. START-UP PROCEDURE AND CONNECTION
3.1
.Using toggle switches on the front panel set necessary mode of operation ;
3.2.
In case of using RN-111M as Minimal/Maximal protection relay, Minimal protection relay or time relay
connect wires according Figure 2,vers.a.
If RN-111M is being used as a maximal voltage protection relay power load should be connected
according Figure 2,vers.b
.
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.
3.3.
Connect RN-111M (contacts
5, 8)
to the power circuit.
3.4.
By spinning the knobs on the front panel set the required Minimal and Maximal voltage tripping
thresholds (
U
min
and
U
max
) and set necessary turn
ON
time delay (
T
on
). Please pay attention that the
T
on
time should be adjusted taking into consideration the technical documentation and requirements of the
protected power load
– for example – air-conditioners, refrigerators and other compressor containing
equipment usually need 3-4 minutes pause before turn
ON
again after they were disconnected.
3.5
. Give the power supply to RN-111M and by spinning the adjustment knobs set precisely the required
values for the
U
min
,
U
max
and
T
on
. When spinning the knobs on the LED digital display it is shown the exact
value of the adjusted parameter.
4. GENERAL DESCRIPTION AND OPERATION
4.1.
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.
4.2
. MINIMAL/MAXIMAL VOLTAGE PROTECTION RELAY
Power load (contactor coil) should be connected to the output terminals 2(3), 4 (Figure2).
If RN-111M was initially deenergized or the power load was
OFF
due to the wrong voltage parameters
– then
after correct voltage appear on the input terminals and after the time delay
T
on
contacts
1
, 2(3) will open and
contacts 2(3), 4 will close.
If input voltage get lower than minimal voltage threshold for more than 12 seconds RN-111M becomes to
Alarm mode
– contacts
1
, 2(3) close and contacts 2(3), 4 open.
If input voltage gets 60V lower than the minimal voltage tripping threshold
– RN-111M comes to Alarm mode in
0,2 sec. After the recovery of the voltage parameters to the value of hysteresis (4-5V)
– cycle is repeated relays.
If input voltage gets higher than the maximal tripping voltage threshold for more than 1 sec. or the voltage is
30V higher than the maximal tripping threshold during a period exceeding
– then the RN-111M comes to
Alarm
mode
– contacts 2(3), 4 open and contacts
1
, 2(3) 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
T
on
.

MINIMAL VOLTAGE PROTECTION RELAY
Power load should be connected to the output terminals 2(3), 4 (Figure2).
