Harmonic phase angle
The instrument measures the
angle between the single har-
monic of "V" and the single
harmonic of "I" of the same
order. According to the value
of the electrical angle, it is
possible to know if the distor-
tion is absorbed or generated.
Note: if the system has 3
wires the angle cannot be
measured.
Harmonic details
The harmonic contents is dis-
played as a graph showing
the whole harmonic spec-
trum. This value is also given
as a numerical information:

General Specifications
Revenue approval settings
The access to the programming parameters via front key pad and/or serial commu-
nication ports is locked.
The front key pad (up and down keys) allows the displaying of the variables only,
while the communication ports allows the transmission of the variables only
.
A proper "instrument settings" form must be filled up by the user before equipment
supplying.
WM5-96 is supplied with the desired modules plugged and sealed in the proper slots.
WM5-96 fulfils:
the ANSI/IEEE C12.20-1998 requirements;
the CAN3-C17-M84 requirements;
and can be certified according to:
C12.20-1998, class 0.5 (independent labs);
AE-0924 Industry Canada Approval.

Function Description
Figure A
The sign of measured quant-
ity and output quantity re-
mains the same. The output
quantity is proportional to the
measured quantity.
Input and output scaling capability. Working of the analogue outputs (y) versus input variables (x)
Figure B
The sign of measured quant-
ity and output quantity
changes simultaneously. The
output quantity is proportion-
al to the measured quantity.
Figure C
The sign of measured quant-
ity and output quantity re-
mains the same. On the
range X0...X1, the output
quantity is zero. The range
X1...X2 is delineated on the
entire output range Y0 =
Y1...Y2 and thus presented in
strongly expanded form.
Figure F
The sign of the measured
quantity remains the same,
the one of the output quantity
changes as the measured
quantity leaves range X0...X1
and passes to range X1...X2
and vice versa.
Figure E
The sign of the measured
quantity changes but the one
of the output quantity
remains the same. The output
quantity steadily increases
from value X1 to value X2 of
the measured quantity.
Figure D
The sign of measured quant-
ity and output quantity re-
mains the same. With the
measured quantity being
zero, the output quantity
already has the value
Y1 = 0.2 Y2.
Live zero output.

NOTE: In case of fault of first insulation the current from the measuring inputs to the ground is lower than 2 mA.
(*) The given insulation is granted among outputs plugged in different slots. The modules equipped with two or four outputs
have therefore non insulation among the outputs. (**) Insulation between the 2 outputs of the same module is 200V for 1 min.

RS422/485 NOTE: additional devices provided with RS422/485 (that is RS 1, 2, 3...N) are connected in parallel. The termina-
tion of the serial output is carried out only on the last instrument of the network, by means of a jumper between (RX+) and (T).

AO1037 4-open collector output connection:
This wiring diagram is valid also for the open
collector module with one or two outputs.
The load resistances (RC) must be designed so
that the close contact current is lower than
100mA; the VDC voltage must be lower than or
equal to 30VDC.
