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.
