SAFETY INSTRUCTIONS
To guarantee correct installation, observe the following instructions:
1) The instrument must be installed by a qualified person
2) The instrument must be installed in an electrical panel which, after installation, leaves
terminals inaccessible
3) The building in which the instrument is installed must have an electrical system
including a switch or a circuit breaker: this must be near the device and in a position
that can be easily reached by operators.
4) A protection device against over-currents must be installed in the electrical system
upstream of the instrument
5) Connect the instrument as shown in the diagrams of this manual
6) Before making contact with terminals, ensure that leads to be connected to the
instrument are not live
7) Do not power or connect the instrument if any part of it is damaged
Note: The network analysers in the ADR-D 230 D22 series are aimed for use in places with
overvoltage category III and pollution degree 2 to EN 61010-1.

The partial meter is automatically zeroed when the scale range is overrun. To set the meter to
zero manually, hold the "SEL" key down for more than 3 seconds
To view the first page again, press the SEL key once more.
BACKLIGHTING
The device's display backlights when the SEL key is pressed: it stays on for 30 seconds after the
last key is pressed.

To view the AT setting, go to page 2 and hold down the SEL key for at least 3 seconds.
Current AT value
To change the AT setting, proceed as follows.
Hold the SEL key down while switching the device on: the display will read in a sequence the
firmware version, the serial number and will flash the AT primary value. To select an AT different
than the flashing value, press the SEL key repeatedly until the desired value appears.
The AT values available are as follows: 5/5A, 10/5A, 25/5A, 50/5A, 75/5A, 100/5A, 125/5A, 150/5A,
200/5A, 250/5A, 300/5A, 400/5A, 500/5A, 600/5A, 800/5A, 1000/5A.
To effect the change, select the AT value and then press the SEL key until the value stops
flashing. The partial energy count will then be zeroed and the voltage page (page 1) will appear
on the display.
Note: If direct connection of current leads is used (I
value) in the AT setting.
SERIAL-COMMUNICATION CONFIGURATION (for MODBUS model only)
The following serial-communication parameters can be accessed: address number, baud rate and
parity.
To read the current serial parameters, go to page 3 and hold the SEL key pressed for at least
3 seconds, until the address page appears. To scroll the other pages push the SEL key: after
viewing the last page the display resumes normal reading.
To set a parameter, go to the relevant page, hold the SEL key pressed until the value flashes,
press it again to change it and then confirm by pressing it long, until the value stops flashing.
OPERATING MESSAGES
PHASE ERROR
On startup the device checks whether the current and voltage terminals are connected correctly.
In case of error the phase error page will be displayed for 3 minutes. The triangular LED on the
left will flash.
To resume correct operation, turn it off, invert voltage or current connections, and turn on
again.
Error conditions occurring during normal operation are indicated by the flashing of the
triangular LED on the left. Voltage, current and frequency values are nonetheless read correctly.
As for the remaining pages, energy counts will not increase, the power factor will be force-set to
1 and the active power value to 0.
OVERFLOW ERROR
When the voltage or current reading range is overrun, the relevant field will flash dots and the
total energy count will be read.
Voltage or current overflow error is indicated on the other pages too. in this case the values
measured will flash.
SERIAL COMMUNICATION
The instrument (MODBUS model only) has an insulated serial output RS 485.
•
The data communication system is based on MODBUS protocol (RTU coding system) and can
be connected to a Master system (PC/PLC)...) on a multipoint line RS 485:
- up to 31 ADRs (slaves) without signal amplifiers, from a maximum distance of 1000m
- up to 247 ADRs (slaves) in groups of 30 separated by proper signal amplifiers
•
Contact the technical assistance service dept. to request documents regarding MODBUS
functions, use of registers and the ADR-view software.
