DIGITAL OUTPUT CONNECTION

The instrument is provided with a passive optoisolated digital output for pulse emission or alarm.

RS485 PORT CONNECTION

The RS485 port allows to manage the instrument in local or remote mode by MODBUS RTU/ASCII protocol. For instrument network connection, install a terminal resistance (RT=120…150 Ω) on the RS485/USB converter side and another one on the last instrument connected on the line. The maximum recommended distance for a connection is 1200m at 9600 bps. For longer distances, lower communication speed (bps), low-attenuation cables or signal repeaters are needed. Refer to the following scheme.

VOLTAGE & CURRENT INPUTS

For Rogowski coil wiring, connect the yellow coil edge to the terminal (signal), and the white coil edge to the terminal (common). Refer to the following picture.

1. WHITE edge
2. Sheath
3. Shield| 4. BLUE wire
5. WHITE wire

POWER SUPPLY

WARNING!
Install a circuit breaker and an over-current device (eg. 250 mA T type fuse) between the instrument power supply and the electrical system.

Before connecting the instrument to the network, check that the network voltage corresponds to the instrument power supply value (85…265 VAC / 110 VDC ±15%).

CONSIDERATIONS ON FULL SCALE CALCULATION

The phase power full scale is the result of a multiplication between PT primary and phase X current full scale (X=1, 2 or 3). If the PT primary and secondary values are set to 1 (direct connection), the phase power full scale is the result of a multiplication between 290V and phase X current full scale (X=1, 2 or 3).
For the current full scale value to be used in the formula, consider the following values according to the selected instrument scale:
Scale 500A >FSA = 700A
Scale 4000A > FSA = 5600A
Scale 20000A > FSA = 28000A

Ex. formula for phase 1 power full scale: FSP1,S1,Q1 = PTpri FSA1 if PTpri=PTsec=1 > FSP1,S1,Q1= 290V FSA1
Ex. formula for system power full scale: FSP∑,S∑,Q∑  = 3 PTpri FSAMAX if PTpri =PTsec =1 > FSP∑,S∑,Q∑ = 3 290V FSAMAX

DIGITAL OUTPUT SETUP

To access User setup loop, on Setup? page press button for at least 3 s. The digital output setup page will be displayed. At first User setup access, the digital output is disabled (NONE) and no parameter is associated. To enable the digital output, press button, the NONE item will start to blink. With or button select the mode:

• AL H=alarm mode, high threshold or negative active power sign
• AL L=alarm mode, low threshold or positive active power sign
• PULS=pulse mode

Confirm with button. For setup description of each digital output mode, refer to the following table.

ALARM MODE SELECTION

1. The symbols which identify the parameter type (e.g. A1=phase 1 current) will start to blink. With or  button select the parameter to be associated to the digital output and confirm with button.
   Selectable parameters: Real time values, active power sign or DMD values. The Activepower sign parameter can be identified by SIGN displayed on the second row.

2. In case of real time or DMD parameter selection, the second row will display threshold value. After parameter selection,the threshold first digit will start to blink.
   With or  button select the digit and confirm with button. Repeat the same procedure for the other digits. The value range changes according to the selected parameter.In case of Active power sign parameter selection, the second row will display the SIGN static text instead of the threshold value.

3. In case of real time or DMD parameter selection, the third row will display hysteresis value. After threshold selection, the hysteresis first digit will start to blink.
   With or  button select the digit and confirm with button. Repeat the same procedure for the other digit. Value range: 0…50%.In case of Active power sign parameter selection, the third row will display the delay value. After parameter selection, the delay first digit will start to blink. With or button select the digit and confirm with button. Repeat the same procedure for the other digit. Value range: 1…60s.

PULSE MODE SELECTION

1. The symbols which identify the parameter type (e.g. -Wh∑=system exported active energy) will start to blink. With or  button select the parameter to be associated to the digital output and confirm with button. Selectable parameters: Energy counters except balance values.
2. The pulse value first digit will start to blink. With or  button select the digit and confirm with button. Repeat the same procedure for the other digits. The value range changes according to the selected parameter.
