Electronic instrument to measure the consumption of active power in single-

phase systems to prevent the activation of the limiter switch of general current

for overload.

PC1R Micro provides for the disconnection of a not priority load if the

consumption of measured power is higher than the prefixed threshold (setpoint)

continuously for a time of settable pre-alarm (Ton). The connection of the load

occurs after a disconnection time (Toff).

SAFETY WARNINGS

During the installation and the operation of the instrument it’s necessary to

observe the following instructions:

1) The instrument must be installed by a qualified person by observing

scrupulously the connection diagrams.

2) The instrument must be installed and activated in compliance with current

electric systems standards.

3) After installation, inaccessibility to the connection terminals without appropriate

tools must be granted.

4) Do not use the instrument for other purposes different from the one specified.

5) The instrument must be installed in a closed electrical panel adequately

protected.

6) In the power supply network a bipolar disconnection must be present.

7) A protection device against over-currents should be installed in the electrical

system, upstream of the device.

8) Before accessing the connection terminals, verify that the leads are not live.

9) Do not power on or connect the instrument if any part of it is damaged.

10) The instrument can be used in environments with overvoltage category III

and pollution degree 2, according to the CEI EN 61010-1 standard.

REFERENCE STANDARDS

Compliance with Community Directives: 2014/35/EU (LVD) and 2014/30/EU (EMCD)

is declared with reference to the following Standards:

• EN 61010-1 • EN 61000-6-2 and 61000-6-3

information to users pursuant to art. 14 of the directive

2012/19 / EU of the european parliament and of the council

of 4 july 2012 on waste electrical and electronic equipment (WEEE)

If the crossed-out bin symbol appears on the equipment or packaging,

this means the product must not be included with other general

waste at the end of its working life.

The user must take the worn product to a sorted waste center,

or return it to the retailer when purchasing a new one.

Products for disposal can be consigned free of charge (without any new purchase obligation)

to retailers with a sales area of at least 400 m

2, if they measure less than 25 cm.

An efﬁcient sorted waste collection for the environmentally friendly disposal of the used device

or its subsequent recycling, helps avoid the potential negative effects on the environment

and people’s health, and encourages the re-use and/or

recycling of the construction materials.

1User Manual

LOADS CONTROL 1 RELAY

Read all the instructions carefully

To prevent the disconnection of all loads downstream of the general counter, the

loads control PC1R Micro must measure the same current of the energy meter.

For this reason the ideal position for the connection of the instrument is immediately

downstream of the general switch.

Two loads or groups of loads must be located and so divided:

• not disconnectable loads, that is to say loads which can’t be disconnected

and that can’t be controlled by PC1R Micro (even if their consumption must be

measured by PC1R Micro to determine the total consumption)

• , which can be disconnected if the absorbed power is disconnectable loads

higher than the prefixed threshold.

Note: PC1R Micro can be used also as a generic controller of absorbed power by

loads under control by placing it upstream of the cable for power supply of loads

themselves.

Clearly with this second application it’s not possible to prevent the disconnection

of the general energy meter, because the absorptions of the loads not controlled by

PC1R Micro are not counted.

DEACTIVATION OF THE CONTROL

It is possible to disable relay switching which normally occurs when the intervention

threshold is exceeded.

• To enable this function, regulate the pre-alarm trimmer to the maximumTon

value and verify that the green LED flashes.

• To restore normal operation, reset the trimmer to the desired value (and inTon

any case lower than the maximum value) and checking that the green LED is

steady on.

DEFINITION AND MODIFICATION OF OPERATION PARAMETERS

• [kW] represents the activation threshold that is to say the maximum Setpoint

value of accepted consumption. Over this value the instrument provides for the

disconnection of the load.

• Ton [seconds] represents the pre-alarm time, that is to say how long the power

must be higher than the setpoint before the load is actually disconnected.

During the pre-alarm time the red LED flashes.

• Toff [seconds] represents the disconnection time, that is to say after how long

the load is reconnected.

During the disconnection time the red LED is on.

Note: the load is connected only if the absorbed power is lower than the Setpoint.

It is not necessary

to respect a particular verse of

the current through the CT.
