PRELIMINARY OPERATIONS
GENERAL INFORMATION
play all the parameters and use the
functions provided to carry out the
following:
FUNCTIONS
The Diris Am is an instrument for
measuring and metering electrical
values for single, two and three-pha-
se LV/HV electrical networks. From
the front panel (6 keys and LED dis-
plays) you can programme and dis-
• instantaneous, average and maxi-
mum apparent power S over a pro-
grammable integration time (5 to 60
min.),
• instantaneous and maximum power
factor PF with L (inductive) and C
(capacitive) indications.
• instantaneous, average and maxi-
mum current over a programmable
integration time (5 to 60 min.),
• phase to neutral and phase to pha-
se voltage,
• frequency,
• instantaneous, average and maxi-
mum active power P on 4 display
quadrants (L/C/+/-) over a program-
mable integration time (5 to 60 min.),
• instantaneous, average and maxi-
mum reactive power Q on 4 display
quadrants (L/C/+/-) over a program-
mable integration time (5 to 60 min.),
HOUR RUN METER
Metering in 1/100th of an hour for
operating time, with reset to zero.
OPTIONS
Options are factory set and are avai-
lable as follows:
• Energy metering
Active (0 to 99 999 999 kWh) and
reactive energy metering on 4 qua-
drants. Two programmable pulse
outputs can be used for active,
reactive or apparent energy mete-
ring, with a programmable value
(0.1, 1, 10, 100 kWh, kvarh or kVAh
NB:
Meters can be programmed to reset
to zero (programme access via
access code).
and 1 or 10 MWh, Mvarh and MVAh)
and duration (100 ms to 900 ms).
• Communication
An RS485 serial link (2 or 3 wires)
with JBUS/MODBUS protocol for
use with a PC or PLC.
