THREE-PHASE NETWORK ANALYSER 90A
Read all the instructions carefully
The ADR-D 400 D90 network analyzer is a direct connection digital multimeter for
three-phase systems up to 90 A for true effective value measurements (TRMS). The
isolated RS-485 serial output allows, through the MODBUS protocol functions and
the use of the relative registers, to connect the analyzer to a Master device (PC/
PLC...) for data visualization and archiving.
SAFETY INSTRUCTIONS
During the installation and operation of the device, observe the following
instructions:
1) The device must be installed by a qualied person
2) The device must be installed in an electrical panel which, after installation,
leaves terminals inaccessible
3) The electrical system in the building where the device is installed must
feature a switch or 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 device as shown in the diagrams of this manual
6) Before making contact with terminals, ensure that conductors to be
connected to the device are not live
7) Do not power or connect the device if any part of it is damaged.
NOTE: Network analyzer ADR-D 400 D90 is aimed for use in places with over-
voltage category III and pollution degree, 2 as per EN 61010-1

INSTALLATION
Network analyzer ADR D 400 D90 may only be used in three-phase systems 230 Vac
Phase-neutral, with 400 Vac Phase-Phase voltage between lines.
For installation, follow the connection diagram shown above:
− for 4-wire three-phase systems (3 phases + neutral) also with non-symmetrical and/
or non-balanced systems, connect the neutral lead to terminal 1
− for 3-wire three-phase symmetrical and balanced systems, it is possible not to
connect the neutral lead
For correct measurement, the 3 phase leads coming from the distribution panel must
be inserted in the through holes vertically from above; failure to do so will cause a
connection-error warning to appear on the display. In case of a connection error, the
display will indicate which phase or phases are misconnected (cfr. “ERROR MESSAGES
– MISCONNECTION” ).

SERIAL OUTPUT RS 485
The ADR-D 400 D90 has an isolated RS 485 serial output.
• The data communication system is based on MODBUS protocol (RTU coding system)
and can be connected to a Master system (PC/PLC...) on a common RS 485 line:
− up to 31 ADRs (slaves) without signal ampliers, from a maximum distance
of 1000m
− up to 247 ADRs (slaves) in groups of 30 separated by proper signal ampliers
• For the MODBUS functions and the use of the registers, request the specic
documentation by contacting the technical assistance service.

ERROR MESSAGES
MISCONNECTION
In the rst two minutes after power-up, misconnection is indicated by the reading “Err
PHASE” and the relevant phase number.
Misconnection of phase 2 Misconnection of phases 1, 2 ,3
Two minutes after power up the “Err PHASE” reading disappears. The arrow
corresponding to the misconnected phase will then ash on the display.
The latter warning will stay on the display until the error is removed
Misconnection of phase 2 Misconnection of phases 1, 2 ,3
(arrow 2 ashing) (arrows 1,2,3 ashing)
Possible error causes are:
− one or more phase leads from the distribution panel may have been inserted upward
into the current-measuring through holes
− the phase connected to the voltage input terminals (2,3,4) is not the same one
inserted into the corresponding through hole. For instance: the phase connected to
terminal 2 (phase 1) may have been inserted in the middle through hole (phase 2)
OVER-VOLTAGE OR OVER-CURRENT ERROR
This occurs when the TRMS value of one or more input phases exceeds a voltage of 265V
or a current of 95A. This error is indicated by the ashing of all display pages. Voltage or
current overow is indicated by three dashes “---” on the relevant eld
V2 > 266V I1 and I3 > 95A
The device resumes correct value readings when voltage and/or current get back into
the admitted ranges (V ≤ 253 and I ≤ 90A respectively).

CONFIGURATION ERROR
Every 30 seconds the software checks conguration settings in some internal registries;
if an invalid datum is detected, the device is automatically recongures until the error
disappears.
During these steps, the device does not measure any quantity and reads “CHIP Error”
Conguration error
If the error warning stays on even after disconnecting and reconnecting the device from
the mains, the latter must be considered as faulty.
