ELECTRICAL CONNECTIONS
You can remove the internal part of the device from its case
without removing connections. Signals are distributed in the rear
panel as shown in Figure 6.
Figure 6 – Electrical connections of NC400-6
POWER SUPPLY - POWER
Before making the power supply connection (terminals 1 and 2),
check the power voltage specified in the NC400-6 lateral
identification label. It is recommended to install electrical safety
devices.
Installation must have a switch that is able to turn off
all electrical current leads. This device must be
mounted close to the NC400-6, with easy operator
access and identified as a device that disconnects
the instrument.
Input, output and power connections, according to
Figure 6.
OUTPUTS – OUT1 / OUT2
OUT 2 (terminals 3 and 4) is always a relay. OUT1 (terminals 5 and
6) can be a relay or voltage pulse. See Item 6 – Identification to
determinate the OUT1 type.
Connect outputs respecting the specified capacity for voltage and
current. Check polarity for pulse output.
Counting and command inputs – COUNT1 / COUNT2 / RESET
COUNT1, COUNT2 and RESET inputs accept connections of NPN
or PNP sensors, dry-contact or voltage pulse. The type of signal is
configured through the
SEnS.tY SEnS.tY SEnS.tY SEnS.tY parameter, and all inputs must be
the same type.
Figures 7a, 7b and 7c illustrates connections of those signals to the
COUNT1 input. The same connection scheme applies to the other
inputs.

AUXILIARY SUPPLY OUTPUT
NC400-6 has an auxiliary power supply output for external sensors
(terminals 7 and 8). Check polarity and current limits before
connecting external devices to the auxiliary supply. Inputs 8 and 9
are internally connected (not isolated)
CONFIGURATION
The proper operation of NC400-6 depends on the proper
configuration of all parameters. Read the manual carefully and
thoroughly before using the equipment.
KEYBOARD AND DISPLAY OPERATION
All configuration operations are performed through the front panel
display and keyboard. The following are the panel elements and how
to operate them.
RUN : It is activated when the display shows
the main counter value.
PM : It is activated when the display shows
the batch counter value.
TOT : It is activated when the display shows
the totalizer value.
OUT1 : It is activated whenever OUT1 is on.
OUT2 : It is activated whenever OUT2 is on.
HOLD : It is activated whenever the counting
input is on hold (because of Hold input
activation, programmed input for key
or configuration in Out1.OP Out1.OP Out1.OP Out1.OP or
Out2.OP Out2.OP Out2.OP Out2.OP ).
COM : Flashes whenever NC400-6 is exchanging data
through the communication interface (optional).
OVFL : When the display shows the value of one of the 3
counters, it means that the counter displayed is in
overflow (counting over 999999 or below 0).
MIN : When the display shows the value of the main counter
or totalizer, it means that the counter displayed is with
a value below the offset (
OFF.C OFF.C OFF.C OFF.C or OFF.t OFF.t OFF.t OFF.t ).
MAX : When the display shows the value of the main counter,
the batch counter or totalizer, it means that the counter
displayed is with a value above
SP2C SP2C SP2C SP2C , SPbAt SPbAt SPbAt SPbAt or
SPtot SPtot SPtot SPtot , respectively.
