2-1 Overview and Features

This section describes the overview and features of the wireless pushbutton switches system.

2-1-1 Overview

The wireless pushbutton switches system consists of A2W-R-WC1 Master Units and
A2W-T-WC1 Wireless Pushbutton Switches. At the push button switches side, it has no wiring (i.e.,
wireless) and no power supply. The operation signal of the Wireless Pushbutton Switches is transmitted
to the Master Unit, and transistor output is made from the Master Unit.

This system can reduce disconnection troubles occurring in the equipment using existing wired
switches and can reduce time and expense when changing the layout.

Reliability is improved by wireless communications functions such as sub GHz band, master-slave
communications, and reception confirmation LEDs.

Hereafter, the A2W-T-WC1 Wireless Push Button will be called "Slave button" in comparison with the
"Master Unit".

Overview of the System Configurations

The Overview of the wireless pushbutton switches system is shown below.

Pressing the Wireless Pushbutton Switch will be generated self-generated power. Using the power, the
operation signal is transmitted wirelessly to the Master Unit. Receiving the operation signal, the Master
Unit returns the reception confirmation signal to the Wireless Pushbutton Switches by radio and outputs
a one shot (i.e., 500 ms) transistor output to the external devices such as PLCs.

External devices such as PLCs output signals from the Master Unit to the Display board and program­mable terminal (PT), etc.

Wireless Pushbutton Switch User’s Manual (A265)

2 Overview

2-1-2 Features

The Wireless pushbutton switch system has the following features.

• Up to eight Slave buttons (pushbutton switches) can be assigned to one Master Unit.

• Self-power generation by button operation eliminates the power supply for Slave buttons (pushbutton
switches). That allows you to carry Slave buttons.

• The transistor output from the Master Unit is a one-shot operation.

• Master-slave wireless communications are realized by sending ON/OFF data from the Slave buttons
to the Master Unit and responding reception confirmation to the Slave buttons from the Master Unit.

• The radio frequency in the sub GHz band used enhances the characteristics that radio waves reach
and goes around, and also makes it suitable for use in places with many obstacles.

• When you press the Slave button (pushbutton switch), you can confirm the success or failure of
transmission with the Master Unit by the color of Slave button's indicator. Therefore, even in places
where wireless communications are unstable, you can check the transmission and reception results
by retrying the operation.

• A High-sensitivity Magnetic-base Antenna is provided to place the antenna in a position avoiding
obstacles. This antenna is available when installing the Master Unit inside a control panel.

• Multiple Slave buttons can be assigned to the same output number of one Master Unit.
(Up to 8 Slave buttons can be registered to one Master Unit.)

• Instructions to automatic guided vehicles (e.g., instruction to stop)

• Instructions from manned guided vehicles (e.g., Instructions for opening and closing shutters or
doors of warehouses)

• Instructions to the machine (e.g., stopping, inching, opening and closing doors)

2-2 System Configurations

This section describes the system configurations of the wireless pushbutton switches.

After pressing a Slave button, wait for 100 ms before pressing the next Slave button, because
the Master Unit can not receive at the same time signals of multiple Slave buttons.

System Configuration

When using the Pencil antenna that comes with the Master Unit, do not install the antenna in a metal
panel, because the wireless performance is significantly reduced. When installing the Master Unit in a
panel, use the High-sensitivity Magnetic-base Antenna so that the antenna can be installed outside the
panel.

2-2-3 Relationship Between Slave Buttons and Master Unit

Up to 8 Slave buttons can be assigned to one Master Unit.

A single Master Unit can output eight transistors.

• A single Slave button can be assigned to each output of the Master Unit.

• In addition, the following duplicate assignments are also possible.

(a) Multiple Slave buttons can be assigned to the same output of the Master Unit.

Observe the following precautions in this case.

If you press the Slave button successively at short intervals (i.e., within 500 ms), not all actions of
multiple Slave buttons pressed within 500 ms will be reflected. Only the actions of the Slave button
pushed at the beginning is reflected in the "RCV" LED and output of the Master Unit.

Installation Locations

When selecting the installation locations of the Master Units, consider the following conditions:

• 24 VDC power supply can be supplied to the Master Unit

• To set the Master Unit at a relatively high position. When installing the Master Unit on the floor, the
communications distance becomes short.

• Installation at a higher position will be installed in a more open space. As a result, radio waves will be
more easily reachable without being affected by obstacles.

3-1 Installation and Operating Environment

• Do not place a metal object around the antenna.

Metal objects reflect radio waves, so if there is a metal object around the antenna, the radio waves in
a specific direction may become weak.

Keep the antenna away from the metal object.

Precautions for Correct Use

5-1 How to Register Slave Buttons to

Master Unit

This section describes how to register/delete the Slave buttons to/from the Master Unit.

In ID mode, you can register Slave buttons to the Master Unit.

• If you register a Slave button to the Master Unit in an environment where another wireless
pushbutton switch system is operating around it, it can be erroneously set. Therefore, when
registering a Slave button, perform in an environment where the system of another wireless
pushbutton switch is not operated.

• Register Slave buttons to one Master Unit one by one. Be sure to set the other Master Units
to the RUN mode or TEST mode.

If the power of the Master Unit drops due to an instantaneous power failure or the like while registering
the Slave button, the setting information may not be stored correctly in the Master Unit's memory. Then,
the Master Unit may not work properly at the next startup. When registering, perform it with stable
power supply status.
