OM-633

Power consumption limiters

with a voltage relay function

The OM-633 power consumption limiter is designed for au-

tomatic disconnection of the power supply of the electrical

installation circuit in case of exceeding the set value of power

consumed by the receivers in this circuit as well as for monito-

ring the power supply voltage of this receiver and protecting it

against the effects of voltage increase or decrease beyond the

set values.

»Adjustable threshold of tripping power 1÷10 kW;

»Protection against the drop of UL power supply voltage

(150÷210 V);

»Protection against the rise of UL power supply voltage

(230÷260 V);

»Counter of relay actuations with automatic disconnection

of system power supply after exceeding a set number of

actuations;

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 char-

ge and can give any amount to up to that end point of collec� on, 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 tra-

sh or abandoned in nature, pose a threat to the environment and human health.

»Automatic lock of the system power supply for 10 minutes in

the case in case the power was exceeded fivefold;

»Automatic power-off when the power consumption is 8 times

higher than the set threshold value;

»Automatic power-off when the power consumption is great-

er than 16 kW;

»Adjustable tripping time (1 s÷3 min.);

»Adjustable reconnection time (4 s÷6 min.);

»LED display for indicating power consumption and device

configuration,

Power P

The power limiter allows you to power the circuit when the total

power of the receivers in the controlled circuit is lower than the

one set on the limiter scale. Exceeding the set power consump-

tion threshold in a controlled circuit results in a disconnection of

the power supply to this circuit after a user-set time. The power

supply will be restored automatically after a preset time. If the

power consumed is still greater than the set value, the circuit will

be disconnected again.

Automatic disconnection will also occur if the power consump-

tion is 8 times higher than the set threshold and if the power

consumption exceeds 16 kW. The limiter is locked for 30 seconds.

Voltage UL/UH

This function controls the number of consecutive actuations of

the limiter. When the preset counter value is reached, the limit-

er disconnects the power supply permanently (no automatic re-

turn). The system can be switched on again after a manual reset

of the lock. By default (parameter 0) the limiter has the lockout

function set to 10 minutes after 5 consecutive disconnections.

Functioning

- 3 -

The accrued value of the counter is reset in case of permanent

operation of the limiter longer than 10 minutes.

CTO trigger counter

This function controls the number of consecutive actuations of

the limiter. When the preset counter value is reached, the limit-

er disconnects the power supply permanently (no automatic re-

turn). The system can be switched on again after a manual reset

of the lock. By default (parameter 0) the limiter has the lockout

function set to 10 minutes after 5 consecutive disconnections.

The accrued value of the counter is reset in case of permanent

operation of the limiter longer than 10 minutes.

Operating mode

In operating mode, the display shows the value of the power

consumed. Led R indicates contact status: off - contact open

(position 7-9); on- contact closed (position 8-9). After pressing

the  button, the display shows the current measured voltage

value. After pressing the  button, the display shows the cur-

rent measured value of the disconnection counter.

Indication of emergency states

-UH exceeding the upper voltage threshold

-UL exceeding the lower voltage threshold

-O- permanent disconnection when the disconnection

counter is exceeded

-P-/0.15 exceeding the threshold of the power consumption

limit. The information about the tripping and the

re-start time is displayed alternately and cyclically.

The information about the tripping and the re-start

time is displayed alternately and cyclically.

Lock reset

After exceeding the value of the trigger counter.

Press and hold the (minus) button to reset.

The limiter will start operation with the previous settings.

Restart

After the power supply is switched on, the limiter starts working

after 10 seconds. The display shows the remaining time to start.

Setting parameters:

-P- disconnection power; range 1÷10 kW; step of 0.1 kW

-UH upper threshold of disconnection voltage; range

Cto disconnection counter; range 0÷20; step of 1. For a

value of 0, the 10 minutes lock function is activated

at 5 disconnections.

Programming

- 5 -

Press the  button sequentially to select a setting parame-

ter. After 2 seconds, the value of this parameter is automatically

displayed. To enter the editing mode, press the  button

again and hold it for 3 seconds until the display blinks. Then set

the correct value of the parameter with the  buttons. After

4 seconds of inactivity, the parameter will be saved automatical-

ly and the limiter will switch to operating mode.

1.Turn off the power supply.

2.Fix the limiter on a rail in the control box.

3.Connect the power supply of the limiter to terminals 1-2.

It is essential to connect L to terminal 2 and N to ter-

minal 1.

4.Connect the power supply of the controlled circuit or contac-

tor coil in series via terminals 8-9.

5.Lead the control circuit cable through the through-channel.

(points).

6.Set the operating parameters.

The power limiter should not be used in systems with

electronic ignition (energy-saving fluorescent lamps),

pulse power supplies, and other devices generating

higher harmonics than 3 and above.
