CHAPTER 1: PULSE OUTPUTS MODULE
The DIRIS A can be equipped with 2 pulse outputs modules easily affected to active energy in kWh (EA±), reactive in kvarh (ER±)
and apparent in kVAh (ES).
The pulse outputs are configurable, with a rate of pulses of 0,1k; 1k; 10k; 100k or 1000k, and a pulse duration from 100 ms to 900
ms.
1.1 - Application:
Visualisation of positive active energy meter kWh (EA+) with PLC.
It is recommended not to exceed 1 pulse per second.
Example 1: Instantaneous power displayed by the DIRIS: 105kW
Calculation of the minimum pulse rate:
105 000 W / 3600 s = 29,17W/s
In this case a pulse weight of 100 Wh can be chosen.
DIRIS configuration (see instruction manual: 876 584 or 876 585):
Pulse output type : OUT 1 TYPE = EA+ (positive active energy)
Pulses weight = Out 1 VAL = 0,1 (0,1 kWh)
Pulses duration = Out 1 DUR = 100 (100 ms)
Example 2 : Instantaneous power displayed by the DIRIS: 1895 kW
Calculation of the minimum pulse rate:
1 895 000W / 3600s = 526.3W/s
In that example, a pulse weigh of 100Wh would be too low (that would mean 5 to 6 impulses per second) it is
necessary to program a pulse weigh of 1kWh.
DIRIS configuration (see instruction manual: 876 584 or 876 585):
Pulse output allocation : OuT 1 TYPE = EA+ (positive active energy)
Pulses weight = Out 1 VAL = 1 (1kWh)
Pulses duration = Out 1 DUR = 100 (100ms)

CHAPTER 2: 2 ANALOG OUTPUTS MODULE
The DIRIS A can be fitted with 1 or 2 analogue (0/4–20mA) outputs module. Each module has 2 analogue outputs.
Each output can be assigned to the following values: 3I, In, 3U, 3V, F, P±, Q±, S, PF
L/C
.
On each output, it is possible to configure the value for 0, 4 and 20mA.
2.1- Application:
Example 1: Configuration of output 1 on current I1 with 100A at 4mA and 2500A at 20mA.
DIRIS configuration (see instruction manual : 876 586):
Analogue output type = Out 1 20mA TYPE = 4/20 (4 to 20mA)
Analogue output allocation = Out 1 20mA PAR = I1 (current phase 1)
Value at 4mA = Out 1 20mA LV = 0100 / A (100A)
Value at 20mA = Out 1 20mA HV = 2500 / A (2500A)
Example 2: Configuration of output 2 on total active power P with 0kW at 0mA and
1500kW at 20mA.
DIRIS configuration (see instruction manual : 876 586):
Analogue output type = Out 2 20mA TYPE = 0/20 (0 to 20mA)
Analogue output allocation = Out 2 20mA PAR = P (total active power)
Value at 0mA = Out 2 20mA LV = 0000 k W (0kW)
Value at 20mA = Out 2 20mA HV = 1500 k W (1500kW)

Example 3 : Configuration of output 2 on total active power P with -1000kW at 4mA and
1000kW at 20mA.
DIRIS configuration (see instruction manual: 876 586):
Analogue output type = Out 2 20mA TYPE = 4/20 (4 to 20mA)
Analogue output allocation = Out 2 20mA PAR = P (total active power)
Value at 4mA = Out 2 20mA LV = 1000 kW (-1000kW)
Value at 20mA = Out 2 20mA HV = 1000 kW (1000kW)
Note: To use the analogue output with positive and negative values at the same time, it is necessary to program identical values
for LV and HV.
Example 4: Configuration of output 3 on frequency F with 45Hz at 4mA and 55Hz at 20mA.
DIRIS configuration (see instruction manual: 876 586):
Analogue output type = Out 2 20 mA TYPE = 4/20 (4 to 20mA)
Analogue output allocation = Out 2 20 mA PAR = F (frequency)
Value at 4 mA = Out 2 20 mA LV = 4500 (45Hz)
Value at 20 mA = Out 2 20 mA HV = 5500 (55Hz)
Note: For the frequency, the values for 4mA and 20mA must be programmed on 4 digits; therefore, for 45Hz enter
the value 4500.

Example 5: Configuration of output 4 on inductive power factor PFL with 0,5 for 4mA and
1 for 20mA.
DIRIS configuration (see instruction manual: 876 586):
Analogue output type = Out 2 20 mA TYPE = 4/20 (4 to 20mA)
Analogue output allocation = OUt 2 20 mA PAR = PFL (inductive power factor)
Value at 4mA = Out 2 20 mA LV = 500 (0,5)
Value at 20mA = Out 2 20 mA HV = 1000 (1)
Note: For the power factor, the values for 4 and 20mA must be programmed on 3 digits; therefore, for 0,5 enter the
value 500.
Example 6: Configuration of the analogue output 1 to provide a 30VDC optocoupler
supply to use with the inputs / outputs module . For example, to count the
number of changeover operations or control position (see §3.3)

CHAPTER 3: 2 INPUTS / 2 OUTPUTS MODULE
The DIRIS A can be fitted with 1,2 or 3 IN/OUT module. Each module has 2 inputs and 2 outputs.
The outputs can be used to monitor electrical values or to command equipments.
The inputs can be used for pulses metering or to control equipments status.
3.1- Output used as monitoring (alarms)
Example 1 : Configuration of relay output N°1 to monitor the currents (3I) with alarm if
I<100A or I>800A. Further parameters: 10 % hysteresis, relay status NO and
without temporisation.
DIRIS configuration (see instruction manual: 876 587):
Relay output 1 type = OuT 1 A-Cd TYPE = I (alarm on current)
Alarm : upper threshold = Out 1 Ht I 0800 / A (800A)
Alarm : lower threshold = Out 1 Lt I 0100 / A (100A)
Hysteresis = Out 1 HYST 10 (10%)
Relay time delay = Out 1 TEMPO 000 (0 second)
Relay status = Out RELAY NO (Normally Open)

the upper threshold)

CHAPTER 4 – RS 485 JBUS/MODBUS COMMUNICATION MODULE
The DIRIS A can be fitted with an RS485 JBUS/MODBUS communication module.
This module allows programming and visualizing the electrical values displayed by the DIRIS with a PC, a PLC or any other
system.
The RS485 connection is wired in series according to the EIA 485 with 2 active wire (+, -).
One RS485 line allows the connection of 31 slaves (DIRIS) over a distance of 1500 meters at 9600 bauds.
The number of slaves can be increase by using repeater(s), however, the maximum of slaves is 255 by communication canal.
It is recommended to use twisted pair type cable (LIYCY type ; minimum section: 0,34mm²). In a disturbed
environment or large network (in terms of length) we recommend using 1 shielded pair type LIYCY-CY (minimum
section: 0,34mm²).
Communication frame:
The standard communication frame is following:
Slave address
Function code
Address
Data
CRC 16
According to the JBUS/MODBUS protocol, the transmission time must be less than 3 silences, i.e. the emission time
of 3 characters so that the message is processed by the DIRIS.
The available functions code are following:
- 3 : to read n words (maximum 128)
- 6 : to write one word
- 8 : to diagnose exchanges between the master and the slave via meters 1 ,2, 4, 5 and 6.
- 16 : to write n words (maximum 128)
-
The response time (time out question/answer) is 250 ms maximum.

If the answer corresponds to a negative value, the answer, in decimal value, will be higher
than 32767.
In that case, it is necessary to convert the value in the following way:
First step: convert the value Hexadecimal into binary
Hexadecimal :
F983
Binary :
1111 1001 1000 0011
Second step: reverse the binary
value
Binary :
1111 1001 1000 0011
opposite :
0000 0110 0111 1100
Page 20
MAN 06 033774 – technical_guide_ DIRIS_A40_A41_C.doc40/Z41 - B 20/27
Third step: Add + 1
opposite :
0000 0110 0111 1100
+1
Binary:
0000 0110 0111 1101
Fourth step: convert in decimal
Binary :
0000 0110 0111 1101
Decimal :
1661 kW/100
Last step: multiply by VT*CT ratio
1661*100/10*100/5= 332 200 kW/100 = 332,2 kW

CHAPTER 5 – MEMORY MODULE
5.1. Powers demands configuration (P+/P-/Q+/Q-)
Powers demand storage (load curves) is used to store and analyse consumption of electrical distribution with date
and time.
Exemple 1: Storage of active power (kWh) integrated on 10 minutes and 62 days. With
internal synchronisation (internal clock) and reading by communication.
DIRIS Configuration (see instruction manual: 876 588) :
Memorisation of positive active power (+kWh) = MEMO P+ YES (yes)
Memorisation of negative active power (+kWh) = MEMO P- NO (no)
Memorisation of positive reactive power (+kvarh) = MEMO P+ NO (no)
Memorisation of negative reactive power (-kvarh) = MEMO P- NO (no)
Synchronisation mode = MEMO TOP EXT (external)
Configuration of synchronisation top time = MEMO TIME 10’ (10 minutes)
Activation of date/time function = dAtE tIME YES (yes)
Date configuration = dAtE 31-07-06
Time configuration = tIME 15h10’35"
