The IPL36 is a TRMS wattmeter and IPL36L is a TRMS volt-ammeter, frequency meter. They have a 6 digits display
and allow the measurement, monitoring and retransmission of electrical parameters. Implementation is quick by simply
programming via the front face.
Devices have several options:
 IPL36(L) : Standard current input base version.
 IPL36(L)-Hall : Hall sensor current input base version
 IPL36(L)../R1 : + 1 relay.
 IPL36(L)../R2 : + 2 relays.
 IPL36(L)../S : + 1 analog output.
 IPL36(L)../CMTCP : + Ethernet Modbus TCP/SNMP link.
 IPL36(L)../CM : + RTU Modbus link.

OPERATING MODE
1) Visualization
At power on, the device displays briefly its actual revision number. It’s a message of the form "r.- x.y", where ‘x’ is the
hardware revision and ‘y’ the software revision. Then it displays the currently selected measurement (Volt, A, ....).
2) Displayed measure changing
By pressing the (yes) button, it is possible to change the type of measurement displayed.
The device can thus display:
- The voltage measurement ("V" unit).
- The current measurement ("A" unit).
- The frequency measurement of the voltage inputs only ("Hz" unit).
- The active power measurement ("W" unit) (only IPL36(-Hall)).
- The reactive power measurement ("VAR" unit) (only IPL36(-Hall)).
- The apparent power measurement ("VA" unit) (only IPL36(-Hall)).
- The power factor measurement ("COS" unit) (only IPL36(-Hall)).
- The active energy counter ("kWh" unit) (only IPL36(-Hall)).
Remark:
The type of measurement displayed remains active even when the device is powered off.

3) Energy counter reset
When the energy counter is displayed, it can be reset by pressing simultaneously the & keys. This function can be
forbidden in the "Special Functions" rubric in terminal mode (see p13 §2.9). In this rubric, the counter can also be ini-
tialized to a starting value. The counter is in 32-bit format, and has a resolution of 0.01 kWh. The maximum count value
before overflow is 42.94967295 GWh. The counter is also stored in non-volatile memory every 15 minutes and the last
saved value is recalled at every Power on.
4) Configuration
To access the configuration, push the ‘’ button. It is possible to lock the access in the "Special Function" rubric. If ac-
cess is locked then the message " NOT ALLOWED! " is displayed.

ENGLISH? Push (yes) to choose the English language. Push (no) to go to the next choice.
FRENCH? Push (yes) to choose the French language.
4.2) Inputs configuration
The device comes standard with two voltage inputs (high and low) and two internal current input (internal and external
shunt) on the standard version or with one current input and a +/- 15 V power supply for the -Hall version. Default cali-
bers of the inputs are:
- 600 V for the high voltage input,
- 150 V for low voltage input,
- 5 A for the internal shunt current input,
- 200 mV (200 A) for the external shunt current input (default shunt sensitivity is 1 A/mV).
- 4000 mV for the Hall sensor current input (default configured caliber is 100 A).
The inputs configuration rubric permits to select the measured voltage input, the measured current input, the sensitivity
of the external shunt current input and the measurement response time (integration time for measurement TRMS 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 measure value. For example with a filter of 1 s, the ripple is 0.6% of the TRMS value.

Terminal mode
1) Visualization
The IPL36 or IPL36L can be configured using the RS232 link on the rear of the device.
This requires a USB/Jack or DB9/jack adapter cable, depending on connectors available on the PC, and have a ASCII
emulation program like ‘HyperTerminal ' or else.
Once the device is connected to the PC, it displays the following measurements page every 3 seconds.
IPL36 measurements page: IPL36L measurements page:
VOLTAGE : 230 V VOLTAGE : 230 V
CURRENT : 1.13 A CURRENT : 1.13 A
FREQUENCY : 50.1 Hz FREQUENCY : 50.1 Hz
ACTIVE P. : 260 W
REACTIVE P. : 22 Var
APPARENT P. : 259 VA
POWER FACTOR : 0.99
ACTIVE E. : 0.05 kWh
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 handbook explains in detail the different configurations possibilities:
Language, input, network, relays, analog output, communication, special functions.
To enter configuration mode, just press "C" key. The message ‘ConF’ is displayed in front.
2.1) Method
during the configuration, 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.
- if you want go back to measure mode without taking notice of modifications made before, just press the escape key.
- If there is no action on a key during 2 minutes, device goes back in measure mode without taking notice of the modifi-
cations made before.

SOMMAIRE
E 11
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 with standard device).
- Measure response time.
2.4) Network
The wiring options on the network are:
- Alternative: single-phase or balanced three phases with neutral.
- Continuous.
It is also necessary to configure:
- The Potential Transformer ratio,
and on a standard device:
- The Current Transformer ratio (1A/5A input) or external current shunt sensibility (200mV input).
or on a -Hall device:
- The Hall sensor current caliber.
2.5) Relays
The device can, by /R1 or /R2 option, provide respectively 1 or 2 independently configurable alarm relays.
Each relay has two operating modes:
- Threshold detection (alarm) or,
- Energy metering (IPL36(-Hall) only).
The threshold detection rubric, allows to activate or deactivate the alarm on threshold overrun.
Threshold detection parameters are:
- Monitored value: voltage, current, frequency, on IPL36 and IPL36L.
and active power, reactive power, apparent power, power factor, on IPL36.
- Type of detection: high or low threshold.
- Threshold and hysteresis value.
- Front face adjustment possibility.
- Security.
- Activation and deactivation delays.
If the alarm detection is activated it 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 Front face threshold adjustment is authorized by default.
This possibility can be deactivated if the adjustment must be inaccessible in front face, only the visualization is then pos-
sible.
The security function allows to choose between the activation or the de-activation of the relay when alarm is activated.

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.
The energy count rubric allows you to activate or deactivate the use of the relay for energy metering.
For this mode, the only parameter to be configured is the counting pulse weight. In this mode, at each count pulse, the
relay is switched on for 150 ms.
2.6) Analogical output
The device can, by the /S option, provide an analogical output, insulated and configurable.
Output parameters:
- Current output (mA).
- Voltage output (V) with strap connected (see wiring p23).
- Low and high output scales.
- Monitored value: voltage, current, frequency, on IPL36 and IPL36L
and active power, reactive power, apparent power, power factor, on IPL36.
- Low and high input measure scales.
- Limitation.
- Response time.
The limitation allows to bound the output signal swing to the configured output scales for any input signal swing over-
flow.
The response time allows to smooth the TRMS measure ripple transmitted on the analogical output signal. It is adjust-
able from 0 to 60 s.
2.7) Setting of communication parameters
2.7.1) MODBUS TCP (option /CMTCP)
The parameters are : IP address, IP mask and gateway address.

4) Measure tables
4.1) Floating point format data
The register address are the same as the table for MODBUS-TCP communication. The measure are in floating point
format number except for the alarm status register (16 bits).
4.1) Integer format data
The register address are the same as the table for MODBUS-TCP. This table lists the measures in 32 bits integer format
and one 16 bits register for the alarms state (address 18).
The values given in this table represent the direct measurements. That is to say, regardless of the coefficients as the PT
ratio, the CT ratio (internal shunt or Hall sensor) or the external shunt sensibility.
Note:
On a IPL36(L)-Hall, the CT ratio parameter is always equal to one.

MODBUS TCP Communication
1) Features
Link: Ethernet
Baud rate: 10/ 100 base T
Default IP address: 192.168.0.253
Port: 502
IP protocol: Modbus TCP
Connector: RJ45
Reading operation: Code function 03, 04
Writing operation: Not allowed
Data type: Measure value, State of alarms.
Data format: - Measure in floating point and 32 bits signed or unsigned integer format.
- State of alarms in 16 bits format.
2) Multi master using
The IPL.../CMTCP supports to be access by master with different IP address (6 max). However, care must be taken that
the average network load does not become too large. A network higher load can cause communication error due to the
traffic.
The average response time to a read request is around 50ms.

4.2) 32 bits integer format
This table lists the measures in 32 bits integer format and one 16 bits register for the alarms state (address 18).
The values given in this table represent the direct measurements. That is to say, regardless of the coefficients as the PT
ratio, the CT ratio (internal shunt) or the external shunt sensibility.
4.2.1) Calculation of actual values
The coefficients are at the following addresses:
- PT ratio x100: 12 & 13
- CT ratio x100: 14 & 15
- Sensibility x100: 16 & 17
To find the actual values you must:
- Multiply the voltage value (addresses 00 & 01) by the PT ratio, and divide the result by 10,000.
- Multiply the current value (addresses 02 & 03) by the CT ratio (internal shunt or Hall sensor) or external shunt
sensitivity and divide the result by 10,000.
- Multiply the values of powers by the PT ratio and the CT ratio or external shunt sensibility, and divide the result
by 10,000.
