SAFETY ALARMS
The following symbols appear in the device and throughout this
manual to call the user’s attention as to important information related
to safety and device use.
CAUTION:
Read manual carefully before
installing and operating the device
CAUTION OR DANGER:
Risk of electrical shocks
All safety recommendations must be followed as to warrant the
individual’s safety and prevent damage to the instrument or system. If
the instrument is used in another way other than that specified in this
manual, the equipment safety protections may not work properly.
Over Temperature Protection
When a system is designed, it is fundamental that one considers the
consequence of any failure in any component of such system. In
temperature control application, danger is even higher when heating
remains constantly on. In applications where physical damage or
device destruction may occur, the installation of an independent
protection device is recommended, which has its own temperature
sensor and can turn off the heating circuit in case of over heating. Note
that the counter output relays of NC400-6 do not offer protection to all
failure conditions.
INTRODUCTION
NC400-6 is an advanced 6-digit counter that also performs batch and
totalizer counting operations. It has two outputs with independent and
configurable presets that can be triggered based on counting, batch
or totalization values. Its 2 outputs allow for an independent timed
triggering.
The counting input can be configured to read dry-contact, voltage
pulse, NPN our PNP sensor connections. Sensors may be powered
by an internal power supply.
Counting mode can be configured as progressive, regressive,
quadrature, ADD or SUB. Several reset modes — automatic or
manual — can be configured. Manual reset can be generated by a
digital input or key from the front panel.
DESCRIPTION
The NC400-6 counter and its configuration parameters are divided in
the following blocks:
•Inputs
•Main counter
•Batch counter
•Totalizator counter
•OUT1
•OUT2
Each of these blocks has its own set of configuration parameters,
which together determine how the device works. A summary of the
operation of each block is presented below as well as their
parameters.
INPUTS
NC400-6 has three inputs that can be configured to read contacts,
NPN sensors, PNP sensors or voltage pulse connections. All inputs
must receive the same type of input signal. Functions of each input
are:
COUNT1: Main counting input
HOLD/COUNT2: Input to hold counting or second counting input. The
second counting input is required when the NC400-
6 counter increases or decreases actions are
determined by an external signal (quadrature
signals, for example).
RESET: Input for external reset of counters and/or outputs.
The following configuration parameters are directly related to the
operation of inputs:
SEnS.tY

Selection of type of signal (contact, pulse,
NPN, PNP).
Coun.tY

Selection of counting speed (slow or fast).
Coun.UP


and use of COUNT2 input.
MAIN COUNTER
It counts pulses from inputs, showing the value in the display after
multiplying it by a configurable scaling factor. Manual or automatic
reset. Two Set points can be defined (presets); when they are
reached they produce configurable actions (enable output, increment
batch counter, reset counter etc.) The following configuration
parameters are directly related to the main counter operation.

COUNTING MODES
The
Coun.tY
parameter selects the counting mode as slow or fast.
In the slow counting mode, a filter is applied to the counting signals,
limiting the maximum pulse frequency, which is necessary to count
the number of activations of electromechanical contacts. In the fast
counting mode, NC400-6 operates up to the maximum frequency
specified for the input signal. The frequency limits for each mode are
defined in Item 5.
The
Coun.UP
parameter defines the main counting direction (UP or
DOWN) and the function of each input. Table 1 shows options for
this parameter.

Table 1 – Counting modes that can be selected with the
Coun.UP
parameter.
The main counting direction affects the main counter:
Main direction UP: Main counter count upstream, starting from
the Offset value defined (usually zero).
Actions can be programmed to take place
in Set point 1 and 2 values.
Main direction DOWN: The main counter count downstream,
starting from the Set point 2 value (
SP2C
).
The action programmed for this Set point
will take place when the counter reaches
the programmed Offset value.
The totalizer direction is always up.
Operation descriptions in this manual consider that
the NC400-6 counter is operating in the UP direction.
To operate in DOWN direction, refer to the
explanation above.
You can select functions for COUNT1 and COUNT2/HOLD inputs:
ADD: Progressive counting input.
SUB: Regressive counting input.
HOLD: Stops the counting input for COUNT1.

NC400-6 Counter
NOVUS AUTOMATION 3/7
Select ADD/SUB: COUNT2 input defines if COUNT1 input is
progressive or regressive.
QUADRATURE: Bidirectional counting mode that uses two
counting inputs to determine if counting is
progressive or regressive. In this counting
mode, the
Coun.tY
parameter is ignored
and the counting mode is always fast.
QUADRATURE 2X: The same as the QUADRATURE mode,
but it counts twice as fast, increasing
resolution. In this counting mode, the
Coun.tY
parameter is ignored and the
counting mode is always fast.
The counter is incremented or decremented whenever the voltage
level in the counting inputs increases (rising edge) except in the fast
counting mode (
Coun.tY
=
1
) in COUNT1 input.
The most representative counting modes are shown in Figures 2 to
5. Low and High levels in the following figures correspond to voltage
levels in these inputs with PNP sensor or Voltage pulse. For the case
of NPN sensors or dry contact, signals will be reversed.

SERIAL COMMUNICATION (OPTIONAL)
Optionally, NC400-6 can be delivered with an asynchronous master-
slave serial communication interface RS-485 to communicate with a
supervisor computer (master). The counter is always the slave.
Communication always start with the master, which sends a
command to the slave address with whom it wants to communicate.
The addressed slave undertakes the command and sends the
response to the master. NC400-6 also accepts broadcast
commands.
FEATURES
•Signals compliant with the RS-485 standard. MODBUS (RTU)
protocol. 2 wire connection between 1 master and up to 31 (able
to address up to 247) instruments in bus topology.
Communication signals are electrically isolated from the rest of
the device;
•Maximum connection distance: 1000 meters;
•NC400-6 disconnection time: Maximum 2 ms after the last byte;
•Fixed communication speed (Baud Rate): 9600 bps;
•Number of data bits: 8, no parity. Number of stop bits: 1;
•Transmission onset and response time: maximum of 100 ms
after command.

Addres

NC400-6 counter communication address.
OVERFLOW AND UNDERFLOW
If the counter is at
0
and it receives a pulse to decrement, the
counter will show
999.999
and turn the OVFL flag on. This means
that the counter rolls to
999.999
. If it increments beyond this, it will
roll back to
0
, clearing OVFL flag.
On a similar way, when the counter is at
999.999
and it is
increased, it will roll to
0
and turn the OVFL flag on. When it
decreases again below
0
, it will turn the flag off and roll back to
999.999
.
Note: The setpoints and output control have no effect while OVFL
flag is on, except those who are cleared by time.
INSTALLATION
PANEL MOUNT
NC400-6 must be installed in a papel. To install, follow the steps
below:
1. Make a panel cutout of 45.5 x 45.5 mm;
2. Remove the clips from NC400-6;
3. Insert NC400-6 in the frontal panel cutout;
4. Replace clips in NC400-6 and press them tightly to clamp the
counter to the panel.
INSTALLATION RECOMMENDATIONS
•Input signal wires must be installed in grounded conduits and
away from power or contactor wires+
•Instruments must be powered only by an exclusive power supply.
•System failure should always be taken into account when
designing a control panel to avoid irreversible damage to
equipment or people. The output internal relay does not warrant
total protection.
•Installing RC filters (47 Ohms and 100 nF, serial) is strongly
recommended at contactor coils or any other inductors.

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
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.
