ment subject to contact with water.

32. The whole system may stop depe nding on how the po wer su pply is turned ON or OFF.

Turn ON or OFF the power supply according to the specified procedure.

33. Signals from the touch switches may not be input if the switches are p ressed consecu-

tively at high speed. Confirm each input before proceeding to the next one.

34. To use numeric input functions safely, always make maximum and minimum limit set-

tings.

35. Do not use benzene, pa int thinner , or other v olatile solv ents, and do not use chemically

treated cloths.

36. The PT uses an analog touch panel. De terioration over time can cause the touch points

to move. Calibrate the touch panel if the touch points move too much.

37. Water resistance will be lost if the front sheet is torn or is peeling off. Do not use the PT

if the front sheet is torn or is peeling off.

38. The Rubber Packing will deteriorate, shrink, or harden depending on the oper ating en-

vironment. Inspect and replace the Rubber Packing periodically (approximately once
per year).

39. T o use the NV3W in an environment with strong noise, connect the following noise filter

to the power supply line:
RSEL-2001W manufactured by TDK-Lambda Corp.

40. A Waterproof Packing cannot be reused. To ensure waterproof performance, replace

the Waterproof Packing with a new one each time you reinstall the PT.

Conformance to EC Directives

This product is EMC compliant.

● Concepts

OMRON products are electronic devices that are incorporated in machines and manufac­turing installations. OMRON PTs conform to the related EMC Directives (see note) so that
the devices and machines into which the y are built can more easily conform to EMC direc­tives. However, customers may use a wide variety of equipment and manufacturing instal­lations. Therefore the customer must check whether the Directives are satisfied for the
actual system. EMC-related performance will vary depending on the configuration, wiring,
and other conditions of the equipment or control panel in which the PT is installed. The
customer must, therefore, perform final checks to confirm that the overall machine or
device conforms to EMC standards.

Note The applicable EMC (Electromagnetic Compatibility) standards for NV-series

PTs are as follows:
NV3W: EN 61000-6-2, EN 61000-6-4
NV3W-V1/NV4W or NV3Q: EN 61131-2

● Conformance to EC Directives

NV-series PTs conform to EC Directives. To ensure that the machine or device in which
the NV-series PT is used complies with EC Directives, the PT must be installed as follows:

• The NV-series PT must be installed in a control panel.

• You must use reinforced insulation or double insulation for the DC power supply and
the DC power supply must ha ve minimal voltage fluctuations and provide a stable out­put even if the power supply input is interrupted for 10 ms.

• NV-series PTs complying with EC Directives also conform to the Common Emission
Standard (EN 61131-2 or EN 61000-6-4). Radiated emission characteristics (10-m
regulations) may vary depending on the configuration of the control panel used, other
devices connected to the control panel, wiring, and other conditions. You must there­fore confirm that the overall machine or equipment complies with EC Directives.

• This is a class A product. It may cause radio interf erence in r esidential are as, in which
case the user may be required to take adequate measures to reduce interference.

Conformance to KC Standards

Observe the following precaution if you use NA-series PTs in Korea.

Class A Device (Broadcasting Communications Device for Business Use)
This device obtained EMC registration for office use (Class A), and it is intended to be

used in places other than homes. Sellers and/or users need to take note of this.

Each Screen Creation The screens displayed on an NV-series PT are created on the NV-Designer.

Screens can be easily created by simply selecting parts from a library and
arranging them.

Parts are available to match the application that is used.
The NV3W is connected using a special RS-232C cable. The NV3W-V1,

NV4W or NV3Q is connected using a commercially available USB cable.

Convert the PT Model for
Screen Data

Communicate with
OMRON PLCs using Host
Link

The NV model conversion function enables screen data to be converted and
reused from a model with a small screen to one with a large screen.

You can connect the PT to an OMRON CP-series, CS/CJ-series, C-series, or
CVM1/CV- series PT using the Host Link protocol.

Communications with PLCs is possible using RS-232C or RS-422A connec­tions.

Multivendor Support with
PLC Model Conversion

You can connect the PT to OMRON PLC or many other global PLC manufac­turers.

Even if you are using different PLCs for different systems, you can easily con­vert the PLC model in the screen data.

Supply Power to the PT
via the PLC Connecting
Cable (NV3W(-V1) Only)

With 5-V NV3W(-V1) models, 5 V can be supplied from the CS/CJ-series or
CP-series PLC via the PLC Connecting Cable. This eliminates the need for a
power supply for the PT, thereby reducing wiring work.

The NV3W and NV3Q provide IP65 protection against dust and water drops.
The NV3W-V1 and NV4W provides IP67 protection.

You can transfer, monitor, or debug ladder diagrams in a PLC from the CX­Programmer running on a computer connected to the PT with the convenient
SPMA (Single Port Multiple Access) function while the PLC and PT are com­municating with each other.

This function is effective during system installation and debugging.

CX-Programmer

Communicate through the PT.

Ladder diagrams can be transferred
and the PLC can be monitored from
the CX-Programmer.

CS/CJ/CP-series PLC

Host Link connection

Use the same cable as
for the NV-Designer.

Reduce the Load on the
PLC with the Write
Address Function

Also, there is no need to change the
cable between the PT and PLC.

Note The CX-Programmer and NV-Designer, however, cannot be con-

nected online at the same time.

You can use the W rite Address fu nction to execute operations to set or reset
bits, set values, perform calculations, and more in PLC memory when condi­tions in the PLC are met. This reduces the load on the ladder program in the
PLC in communicating with the PT.

For example, you can set the Write Bit to write recipes or reset the Data Log/
Alarm History Clear Bit.

Operations are also possible for conditions set for memory in the PT and to
manipulate memory in th e PT.

Switch Label Language You can register up to 16 languages and corresponding character strings for

each part in advance and then change all registered parts at the same time
using a function switch or a command from the PLC.

This allows you to switch the language during operation or s witch t he labe ls in
the same language.

Backup PLC Data in the
PT with the Memory Hold
Function (NV4W and
NV3Q Only and Only
When Battery Is Mounted)

You can constantly back up specified words from the PLC in SRAM in th e PT.
This allows you, for e xample, to bac k up memory areas that are not held in the

PLC when using a CP1E PLC without a battery.
You can also back up the specified data from the internal memory in the PT.

Data Transfer Security You can set a password of up to eight alphanum eric characters f or transferring

screen data from the NV-Designer to an NV-series PT, to prevent screen data
from being transferred when anyone other than the administrator attempts to
read PT screen data.

(NV4W Only)

You can set a password for each operation level of a part to restrict displays
and operations.
Security passwords are managed according to operator level.

The screens can be transf er red using an SD m emory card even if the PT can­not be connected to the NV-Designer.

Project data can be transferred directly by using SD memory cards.
The NV3W-V1, NV4W or NV3Q can connect an OMRON EJ1 Temperature

Controller using Modbus-RTU. The EJ1 Temperature Controllers are con­nected using RS-485 with the PT as the master. Up to 31 Temperature Con­trollers can be connected.

In addition to the previous monochrome display with two shades of gray, you
can now also select a monochrome display with eight shades of gray for
improved screen display quality.

System Configuration Section 1-2

Additional Information

NV-series PTs do not support the 1:N NT Link protocol. Modbus-RTU (PLC:
Master, PTs: Slaves) is required to connect multiple NV-series PTs to one PLC.
(Up to 31 PT can be connected.)
To use Modbus, a communications program for the master is required in the
PLC. Also, notification cannot be performed from the PT. Therefore, response
and updating may be slow or it may not be possible to read all inputs of touch
switches, lamps, and numbers.
For details, ref e r to the NV-series Host Connection Manual (Cat. No. V105).

PLC in MONITOR mode. If the PLC is in RUN mode and the PT attempts
to write to PLC memory, an error code of ER01 will be displayed and mem­ory will not be written. If the PT is connected to a CP-ser ies or CS/CJ­series PLC, the PLC can be in either RUN or MONITOR mode.

You can connect to th e PLC using a built-in serial port on the CPU Unit, a
serial port on a Serial Communications Unit (includes serial connection
through peripheral port), Serial Communications Board, or Host Link Unit.
Use RS-232C or RS-422A to connect to OMR ON PLCs. Do not use RS-485.

1-6-2 NV System Version Upgrade Procedure

The NV system version must be upgraded to use new features. The most
recent firmware is included with the NV-Designer. Upgrade your NV-Designer
designer before you attempt to update the system version of your NV-series
PTs.

Upgrading the System

SD Memory Card (NV4W/
NV3Q Only)

Version Upgrades when
Transferring Screens

Note (1) Updating the firmware in the NV -series PT and transf erring the project are

With the NV4W or NV3Q, the version of the system program can be updated
using an SD memory car d. When saving data to the SD memory card, save
the newest v ersion of th e system progr am on the same card. When the dat a is
read by the PT, the firmware and screen data for the newest version will auto­matically be transferred to the PT.

The firmware can be updated when transferring screens from the NV­Designer by selecting the automatic firmware update.

performed at the same time from the NV-Designer. It is not possib le to up­date only the firmware. (The NV Ver_UP Tool is required.)

(2) When screen data that was created on an old version of the NV-Designer

is read with the new version of the NV-Designer, t he scr een da ta is aut o­matically updated to the new version. (The following confirmation dialog
box will be displayed.)

The following dialog box will be displayed when Transfer is selected from the
PT Menu of the NV-Designer..

same time.

Note Automatically updating the

firmware is possible only
when all data is transferred.

Note (1) Never turn OFF the power sup ply to the PT while t he v ersion is being up-

graded. Also , do not unplug the cable betw een the computer and the NV­series PT. The PT may not restart if transferring the system fails.

(2) T he SPMA functio n cannot be us ed while the version is being up graded

or screens are being transferred.

4-4 Wiring the Power Supply and Serial Communications

This section describes how to connect the NV-series PT power supply and
serial communications.

4-4-1 Power Supply Connections

• Power to the PT is supplied from the serial communications/power supply
connector that comes with the PT.

• The serial communications/power supply connector is a screw terminal
block (8 pins) used to connect PLC serial communications and the power
supply.

• Use the following wire (stranded wire) for the power supply line to mini­mize the influence of noise.

Wiring the Power Supply and Serial Communications Section 4-4

*1 If the XW2Z-200T-4 Cable is used with the NV3W(-V1), 5 V can be sup-

plied from the PLC instead of from an external power supply.
In that case, the power consumption or current consumption shown in the
above table will be provided from the PLC power supply, so be sure to cal­culate the entire 5-V current consumption at th e PLC and to stay within
that range.

■ Wiring Procedure

Use the following procedure to connect the power supply.

1,2,3... 1. Strip the power supply cable.

7 mm

2. Remove the communications/power connector from the PT.
(NV3Q only)

OPEN

3. Insert the wire into the terminal block until it stops, and secure it by tight­ening the screw clockwise.
Using a small flat-blade scre wdriv er, tighten the screws to a torque of 0.22
to 0.3 N·m.

4. Attach the communications/power connector to the PT.

68

Note Observe the fo llowing points to avoid disconnections.

• Be careful not to cut the wire when stripping off the sheath.

• Connect the conductor without twisting the wires.

• Connect the conductor without soldering the wires. Wires can become
disconnected due to vibration.

• Do not apply stress to the cable after the wires have been connected.

• A wire may have a faulty connection if the screw is tightened counter­clockwise. Pull the wire out, chec k the terminal hole, and then con nect the
wire again.

Note (1) When using the PT in environments where strong noise is present, con-

nect the following noise filter to the power supply line.

Manufacturer: TDK-Lambda Corp., Model: RSEL-2001W
(2) Do not connect the DC power supply terminals to an AC po wer supply.
(3) Do not perform dielectric strength tests on the PT
(4) T o protect t he PT from abnormal v oltages on the po wer line , the DC p ow-

er supply must maintain a stable output even if the input power is inter-

rupted for 10 ms, and must have reinforced or double insulation.
(5) A built-in non-isolated regulator is used for the NV3W.

Be careful not to create an unwanted current path with the ground con-

nection. For example, the power supply to the NV may be short-circuited

by functional grounding the NV.
(6) When using a power supply without a built-in protec tive cir cuit, be sure to

supply power to the PT through a protective element, such as a fuse.

4-4-2 Precautions When Supplying Power (5 V) from the PLC (NV3W(-

V1) Only)

If the XW2Z-200T-4 PLC Connecting Cable (2 m with 5-V line) is used, 5 V
can be supplied from the PLC instead of from an external power supply.

Normally, only one device can be connected to pin 6 (5-V power supply) on
the connector for the built-in RS-232C port or the connector for the CP1W­CIF01 RS-232C Option Board of a C P1E CPU Unit. If two devices are con­nected to one CPU Unit, a maximum of two Expansion Units can be con­nected.

If only one device is connected to one CPU Unit, the normal number of CP­series Expansion I/O Units and Expansion Units can be connected. For CP1E
CPU Units with AC power supply, however, it may not be possible to use the
external power supply up to 300 mA. If Expansion I/O Units and Expansion
Units are not connected, the external power supply c an be used up to 300
mA.

For details, refer to the manual for the PLC.

■ CP1H CPU Units

Before perf o rming operation, check that the current consumption f or the ent ire
system is within the specified range for the CPU Unit.

■ CP1L CPU Units with 14, 20, 30, 40, or 60 Points

All CP-series Expansion I/O Units and Expansion Units can be connected.
For CP1L CPU Units with AC po we r supply, howev er, it may not be possible to
use the external power supply up to 200 mA.

If Expansion I/O Units and Expansion Units are not connected, the external
power supply can be used up to 200 mA.

For details, refer to the manual for the PLC.

■ Grounding

Connect the shield wire from the Communications Cable to the shell (FG) on
the RS-422A/485 connector on the Serial Communications Board/Un it.
At the same time, ground to 100 Ω or less the ground terminal on the Power
Supply Unit on the CPU Rack or the Expansion Rack.

Note (1) Use shielded cables for wiring.

(2) Use only one type of transmission cable. Do not use two different types

of cable together.

(3) When cross-connecting lines and using a shielded cable for the RS-485

transmission path, ground only one end of the line. Do not connect it at
both ends. If the line is g rounded a t both ends , it may cause damage due
to the electric potential between the ground points.

Precautions for Correct Operation

Depending on the operating environment, grounding may actually cause prob­lems.
Example: The pow er supp l y lin e for the PT is connected to a functional gr o u nd

• With the NV3W, do not ground the functional ground terminal on the PT if
the positive (+) terminal of the 24-V power supply on the PT is grounded.
Depending on the model of the personal co mputer, the 24-V power supply
may be short-circuited and the PT may be damaged. This is because,
depending on the model of the personal computer connecting to PT, the
SG terminal of the RS-232C port may be connected to the exterior of the
connector. In addition, there is no isolation between the exterior of the NV
tool port and the functional ground. They are connected. Therefore, when
you connect a personal computer, you have in essence connected the NV
GND terminal to the functional ground terminal. When the positive side of
the 24-V power supply to the PT is grounded, grounding the functional
ground terminal will cause short-circuiting and damage as shown below.

4-6 Starting an NV-series PT

Make sure that hardware connections are correct before turning ON the
power supply and starting the PT. This section describes the initial operation
of the PT.

4-6-1 Starting the PT for the First Time

The following screen will be displa yed when the PT is turned ON for the first time.
