The CPL35 and CPL35L are TRMS (AC+DC) converters for measuring, monitoring and retransmission of electrical pa­rameters. Implementation is fast by simple front face configuration. The various output options allow a wide range of ap­plication: measurement, protection, control.

Devices have several options:

 CPL35(L) : standard base version with one analog output.
 CPL35(L)-Rogo : Rogowski sensor input base version with one analog output.
 CPL35(L)-Hall : Hall sensor input base version with one analog output.
 CPL35../R1 : + 1 relay.
 CPL35../R2 : + 2 relays.
 CPL35../R3 : + 3 relays.
 CPL35../S2 : 2 analog outputs.

The technical data sheets are downloadable here: http://www.loreme.fr/fichtech/CPL35_eng.pdf
http://www.loreme.fr/fichtech/CPL35L_eng.pdf

1) Visualization

At power on, the device displays a Hard-Soft revision number (r2-1) during 1 s and then the last selected measurement.

2) Display change

Normally, the device displays the value of the currently selected measurement. Pressing the bottom button toggles the
display to the unit for 2 seconds. The units shown are:

- V for voltage measurement.

- A or mA for current measurement.

- Hz for frequency measurement on voltage inputs 600V and 150V only.

- Vpic for peak voltage measurement (only on CPL35L).

- W for the active power measurement (only on CPL35).

- VAR for the reactive power measurement (only on CPL35).

- VA for the apparent power measurement (only on CPL35).

- COS for power factor measurement (only on CPL35).

During the display of the unit, the operator can change measurement by re pressing the bottom button as many times as
necessary. The unit changes after each press. The device automatically returns to the measurement display mode after
2 seconds.

Note:

The type of measurement displayed remains active even when the device is powered off.

3) Reset of memorized alarms

Simultaneous pressing both buttons provides a alarms reset if the hold function is enabled (see relay configuration
pages 5 and 10) and whether the alarm condition no longer exists.

4) CONFIGURATION

To access the configuration, push the top button. It is possible to lock the access in the "Special Functions" rubric (see

p12). If access is locked then the message "NOT ALLOWED!" is displayed.

Note about value setting:

Use the (+)/(-) buttons to increase or decrease the value. The value is automatically validated after 4 seconds if no
button is pressed.

4.1) Language configuration

LANGUAGE CONFIGURATION? This message scrolls on the display. Push the YES button to access to the rubric.
FRENCH? or ENGLISH? YES button to choose French language, NO button to select the next choice.

4.2) Inputs configuration

The device comes in standard with two voltage inputs (high and low) and three current inputs (2 internals and 1 for ex­ternal shunt) on the standard version and one more current input and a +/- 15 V power supply for the Hall version or with
only one current input for the Rogo version. Default calibers of the inputs are:

- 600 V for the high voltage input,

- 150 V for low voltage input,

- 1 A for the internal shunt current input 1,

- 5 A for the internal shunt current input 2,

- 200 mV (200 A) for the external shunt current input (default configured shunt sensibility is 1 A/mV),

- 4000 mV for the Hall sensor current input (default configured current caliber is 100 Adc).

- 200 mV (2000 A for 100 mV/kA) for the Rogowski sensor current input.

The inputs configuration rubric permits to select the measured voltage input, the measured current input (standard ver­sion only) and the measurement response time (integration time for TRMS measurement value calculation). This pa­rameter is configurable from 0.01 s to 60 s (1 s by default). It should be noted that the amplitude of the ripple on the cal­culated TRMS measurement is inversely proportional to this value. A fast response time implies a strong ripple on the
TRMS measurement value. For example, with a filter of 1 s, the ripple is 0.6% of the measured value.

Terminal mode

1) Visualization

The CPL35 or CPL35L can be connected to a terminal with the RS232 link on the front of the device.

This requires a USB/Jack adapter cable, and have a ASCII emulation program like ‘HyperTerminal ' or else installed on

the PC.

Once the device is connected to the PC, it displays the following measurements page every 5 seconds.

CPL35 measurements page: CPL35L measurements page:
VOLTAGE: 200 V VOLTAGE: 89.2 V
CURRENT: 2.55 A CURRENT: 2.55 A
FREQUENCY: 50.01 Hz FREQUENCY: 50.01 Hz
ACTIVE P.: 260 W
REACTIVE P.: 22 Var OUTPUT 1: 6.27 mA
APPARENT P.: 260 VA OUTPUT 2: 12.16 mA
COSINUS PHI: 0.999

OUTPUT 1: 9.33 mA
OUTPUT 2: 12.16 mA

Remark:

In terminal mode the metrological performance of the device are degraded. It is therefore preferable to limit the
time of use in this mode.

2) Configuration

The device can also be configured by the terminal link.
To enter configuration mode, just press the "C" key. The message ‘ConF’ is displayed in front.

2.1) Method

At the configuration time, different types of questions are displayed. For each one, several answers are possible.
You will find below the detailed description of each case.

2.1.1) Menu selection

example: INPUTS CONFIGURATION The user makes a choice by pressing the keys "Y" or "N".
(Y-N)

2.1.2) Parameter selection
example: VOLTAGE or VOLTAGE
(Y-N)YES (Y-N)NO

Previous choice = YES: - pressing "Y" or "Enter" => choice validation = YES.

- pressing "N" => choice changing = NO.
Previous choice = NO: - pressing "N" or "Enter" => choice validation = NO.

- pressing "Y" => choice changing = YES.

2.1.3) Value acquisition
Example: LOW SCALE
4 mA

There are two possibilities:

- The validation without modification by typing "Enter",

- The modification with simultaneous display followed by validation with "Enter".

Remarks:

- It is possible, when a mistake is made during a value acquisition, before validating it, to go back by pressing on
backspace key. This re-displays the message without taking notice of the mistake.

- In configuration mode, if there is no action on a key during 2 minutes, device goes back in measure mode without
taking notice of the modifications made before.

- In configuration mode, if you want go back to measure mode without taking notice of modifications made before,
just press the escape key.

2.2) Language

The language possibilities are: - French

- English

2.3) Input

The input configuration is made of:

- Voltage input choice.

- Current input choice (only CPL35(L) standard or Hall).

- Measure response time.

2.4) Network
The configurable parameters are:

- Alternative TRMS (AC+DC) or continuous (DC) (only on standard and Hall version).

- Single-phase or three-phase (only on CPL35).
The three-phase mode corresponds to a balanced three-phase wiring with or without neutral (see p16-17). In this mode
the CPL35 multiplies the power measurements by three.

It is also necessary to configure:

- The Potential Transformer ratio,

And on a standard or Hall version:

- The Current Transformer ratio (1A or 5A input) or external current shunt sensibility (200mV input) or the current
measurement unit (A or mA) and the Hall sensor caliber (Hall input).

Or on a Rogo version:

- The Rogowski sensor sensibility in mV/kA (100 mV/kA per default).

2.5) Relays

The device can, by /R1, /R2 or /R3 option, provide respectively 1, 2 or 3 independently configurable alarm relays.

Relay parameters are:

- Choice of alarm: Threshold or window alarm or no alarm.

- Monitored value: voltage, current, frequency on a CPL35(L),
plus active power, reactive power, apparent power, power factor, on CPL35.
For the threshold alarm:

- Type of detection: high or low threshold.

- Threshold and hysteresis value.

- Security.

- Hold function.

- Activation and deactivation delays.
For the window alarm:

- Low threshold value.

- High threshold value.

- Functioning mode.

- Relay activation and deactivation delays.

The threshold alarm works in this manner:

- high threshold detection: .alarm is activated when measure goes above threshold,
.alarm is removed when measure goes below threshold minus hysteresis.

- low threshold detection: .alarm is activated when measure goes below threshold,
.alarm is removed when measure goes above threshold plus hysteresis.

The security function allows to choose between the activation or the de-activation of the relay when alarm is activated
(see chronograms on next page).

The Hold function keeps the alarm activated, even if the measure comes off alarm, and this until it has been disabled by
a reset on the front (see § 3 page 4).

The activation and deactivation delays, configurable from 0 to 600 s set the time above which alarm changes its state
after event appearance and disappearance (see chronograms on next page).

Configuration

 TABLE OF CONTENTS

E 11

The window alarm works in this manner:

In the "RELAY CLOSED IN THE WINDOW" mode

- The relay is activated when the measure >= to the low threshold and <= to the high threshold.

- The relay is deactivated when the measure is < than the low threshold or > than the high threshold.

In the "RELAY CLOSED OUT OF WINDOW" mode

- The relay is deactivated when the measure >= to the low threshold and <= to the high threshold.

- The relay is activated when the measure is < than the low threshold or > than the high threshold.

2.6) Analogical output

In standard the device provides one analogical output, insulated and configurable. It can by /S2 option be equipped
with a second insulated output. The two outputs are configurable independently of each other. They can also be used as
a bipolar +/- 10V output (see "special functions" next page and p18 for wiring).

Configurable output parameters:

- Type of output: Current output (mA) or Voltage output (V) with strap connected (see p15).

- Low and high output scales.

- Response time.

- Limitation.

- Monitored value: voltage, peak voltage (only for output 1 on a CPL35L), current, frequency,
plus active power, reactive power, apparent power, power factor, on a CPL35.

- Low and high input measure scales.

The limitation allows to bound the output signal swing to the configured output scales for all input signal values.

The response time allows a smoothing of the output. It is configurable from 0 to 60 s (set to 0 s at the factory).

The hold time is the time for the detected peak voltage measurement to be maintained on the output 1. It is configur­able from 0,01 to 60 s (set to 1 s at the factory). This configuration rubric is only visible if the user has chosen the
PEAK VOLTAGE measure to be monitored.

2.7) Display
This rubric permits to personalize the measurements display on the front.

The display parameters are:

- Display filter.

- Decimal point display mode.

DISPLAY CONFIGURATION?

To meet its policy concerning EMC, based on the Community directives 2014/30/EU & 2014/35/EU, the
LOREME company takes into account the standards relative to this directives from the very start of the con­ception of each product.
The set of tests performed on the devices, designed to work in an industrial environment, are made in accor­dance with IEC 61000-6-4 and IEC 61000-6-2 standards in order to establish the EU declaration of confor­mity. The devices being in certain typical configurations during the tests, it is impossible to guarantee the re­sults in every possible configurations. To ensure optimum operation of each device, it would be judicious to
comply with several recommendations of use.

2) Recommendations of use

2.1 ) General remarks

- Comply with the recommendations of assembly indicated in the technical sheet (direction of assembly,
spacing between the devices, ...).

- Comply with the recommendations of use indicated in the technical sheet (temperature range, protection
index).

- Avoid dust and excessive humidity, corrosive gas, considerable sources of heat.

- Avoid disturbed environments and disruptive phenomena or elements.

- If possible, group together the instrumentation devices in a zone separated from the power and relay cir­cuits.

- Avoid the direct proximity with considerable power distance switches, contactors, relays, thyristor power
groups, ...

- Do not get closer within fifty centimeters of a device with a transmitter (walkie-talkie) of a power of 5 W, be­cause the latter can create a field with an intensity higher than 10 V/M for a distance fewer than 50 cm.

2.2 ) Power supply

- Comply with the features indicated in the technical sheet (power supply voltage, frequency, allowance of the
values, stability, variations ...).

- It is better that the power supply should come from a system with section switches equipped with fuses for
the instrumentation element and that the power supply line be the most direct possible from the section
switch.

- Avoid using this power supply for the control of relays, of contactors, of electrogates, ...

- If the switching of thyristor statical groups, of engines, of speed variator, ... causes strong interferences on
the power supply circuit, it would be necessary to put an insulation transformer especially intended for instru­mentation linking the screen to earth.

- It is also important that the installation should have a good earth system and it is better that the voltage in
relation to the neutral should not exceed 1V, and the resistance be inferior to 6 ohms.

- If the installation is near high frequency generators or installations of arc welding, it is better to put suitable
section filters.

2.3 ) Inputs / Outputs

- In harsh conditions, it is advisable to use sheathed and twisted cables whose ground braid will be linked to
the earth at a single point.

- It is advisable to separate the input / output lines from the power supply lines in order to avoid the coupling
phenomena.

- It is also advisable to limit the lengths of data cables as much as possible.
