Do not dispose of this device in the trash along with other waste! According
to the Law on Waste, electro coming from households free of charge and can
give any amount to up to that end point of collection, as well as to store the
occasion of the purchase of new equipment (in accordance with the principle
of old-for-new, regardless of brand). Electro thrown in the trash or abandoned
in nature, pose a threat to the environment and human health.

Purpose
Installation
The OM-630 power consumption limiter is designed for conti-
nuous monitoring of the power consumption of the receivers
connected to the three-phase network. The limiter allows to
disconnect the receivers in case of exceeding the specified power
consumption. In addition, the OM-360 controller is equipped with
the power supply voltage control function and protects the
receiving installation from damage that may occur due to dis-
connection of the neutral wire (if the neutral wire is disconnected
before the OM-630 power limiter).
Functioning
The OM-630 relay analyzes the power consumption of the devices
connected to the receiving line on the basis of continuous
measurements of voltages connected to terminals L1, L2, L3 and N
as well as the currents flowing through the built-in current relays.
When the power consumed by the receivers exceeds the value set
by the user than after the TON time the K1 relay and load will be
disconnected. After the TOFF time the K1 relay will reconnect. If
the power consumption is still exceeded, then after the TON time
the load will be disconnected again. This sequence can be repeated
six times, after which the load will be disconnected for 10 minutes.
After that interval the sequence starts from the beginning.
In addition, the limiter is equipped with the power supply voltage
control function and when the voltage drops below 160 V, or
exceeds 260 V, then the limiter will switch off the K1 relay and
disconnect the receivers.
1. Turn off the power supply.
2. Mount the limiter on a DIN rail in distribution box.
3. Connect the controller to the electrical system as shown in the
diagram below paying particular attention to:
a. The order of connection of the supply voltage phases -
connecting phase to the N input may damage the device.
b. Pull the current wires through the holes of the current
transformers from bottom to top (the order of the phases
must be the same as in the case of connecting the voltage
lines) and connect them to the input of the main contacts of
the K1 contactor.
c. Connect the receiving line and the receivers to the output of
the main contacts of the K1 contactor.
d. The K2 relay can be used for indicating the exceeding of the
preset power.
4. Using a screwdriver, set the parameters of the power limiter
operation:
a. Start time and time of the interval between activations in the
event of exceeding the preset power.
b. The level of power limit – the first of the stepping potentio-
meters allows to adjust the rough power value and the
second one allows to set the precise power value.

Technical data
Indications
The configuration of the OM-630 relay is implemented through
four stepping potentiometers located on the front panel of the
relay:
T - Shutdown delay
OFF
If the power consumption is greater than the maximum value for
the time specified with T parameter then the K1 relay will be
OFF
switched off and the relays will be disconnected.
You can select one of the following values: 2 s – 10 s – 30 s – 1 min –
3 min – 5 min – 10 min – 30 min – 60 min.
T - Time interval
ON
Time for which the K1 relay and the receivers will be switched off
in case of exceeding the preset power level.
You can select one of the following values: 1 s - 2 s - 10 s - 20 s - 60 s
- 90 s - 120 s - 180 s - 240 s.
P - Power (rough)
Defining a preset level of power limit.
Potentiometer P allows you to roughly select one of the power
ZG
sections in the range of 5 to 50 kW.
∆P - Power (precise)
Potentiometer PDOK allows you to precisely adjust the power in
the range of 0 to 4.5 kW.
The indication of the power limiter operating state is imple-
mented through four LEDs:
U - power supply
R - relay

<U>- voltage out of range

Description
The system is working properly - the K1 relay and load are both switched-on.
Exceeding of the allowable power - countdown the TOFF time to K1 relay
shutdown.
K1 relay locked due to 6-fold exceeding of the preset power level. Countdown of
the 10 minutes interval to the next load switching-on.
