Software specification

3-1

Transmitter

Transmitter has 3 modes.

1

Sleep mode

When M code (power ON signal) does not exist, transmitter operates in the Sleep mode to
suppress power consumption.
Transmitter periodically attempts to make communication witht the receiver.
Transmitter and receiver communicate with each other and exchange data every 14 - 27
seconds, if the communication is possible.
In this communication, transmitter sends the battery alarm signal to the receiver while receiver
sends the channel information to transmitter.
In case it stays incommunicable for 30 seconds or longer, it changes channels automatically.

When the transmitter is incommunicable with the receiver, it attempts to communicate by
changing channels.
Once the communication is established, its functions will be recovered within 4 seconds.

2

Measuring mode

Once the transmitter received M code (power ON signal) from the receiver, it enters Measuring
mode.
In this Measuring mode, transmitter communicates with receiver every 2ms.
In case the communication is not successful, the transmitter immediately changes channels.

The LED of the transmitter turns on when the contact touches a workpiece.
The transmitter enters Sleep mode automatically if it stays incommunicable for 1 minute.
Even in this case, the transmitter returns to Measuring mode soon after M code (power ON
signal) is sent from the receiver.

3

Matching mode

This mode is the initial setting.
In this wireless communication system, the transmitter stores ID number.
By using ID number, it performs matching with the receiver so that the receiver stores ID.
Once ID number is stored in the receiver, it performs communication exclusively and is never
affected by any other communication systems.
This ID number (transmitter) is stored nonvolatile.

Note: Matching is necessary every time transmitter is exchanged.

3-2

Receiver

Receiver has 3 modes.

1

Sleep mode

Receiver watches 2400-2480 MHz range anytime and find out the empty channel.
It waits until M code (power ON signal) is sent, continuously sending radio wave state (empty
channel information) to the transmitter.
If the communication with the transmitter is successful, the Com. LED (Green) of the receiver is
turned on.
If the communication cannot be achieved, the Com. LED (Green) flashes.
In the Sleep mode, no alarm signal is output to a control device even if the communication is
abnormal.
Batt. LED (Orange) flashes or lights up when the battery runs out, but the receiver does not
output alarm signal.

2

Measuring mode <After receiving Measuring ON Signal (M code)>

After the receiver sends M code (power ON signal) to the transmitter, receiver and other system
enters the Measuring mode.
Then it waits for the sensor ON signal from transmitter. At the same time, it prepares for
sending all alarm signal to control device.
All LEDs become active.

* It depends on battery state at the time of input of M code, and is effective only for 10 seconds.

When M code (power OFF signal) is sent from a control device, receiver transmits it to the
transmitter. Then both receiver and transmitter enter the Sleep mode from the Measuring mode.

3

Matching mode

This mode is the initial setting.
The receiver stores the ID number of transmitter in order not to be affected by any similar
signals.
This ID number (transmitter) is stored nonvolatile.

Note: Matching is necessary every time the transmitter is exchanged.

Possible Cause

Corrective Action

Transmitter power
does not come on.

Dead battery

Replace the battery.

Use of battery other than
recommended battery

Replace the battery.

Battery is installed improperly

Check the alignment of
the electrodes of the battery.

The time the battery has been
removed is too short, preventing
the transmitter from resetting.

Wait for at least 15 seconds
before installing a new battery.

Tranmitter does
not operate even
when the measur­ement cycle is
executed.

Transmitter does not switch to the
Measuring mode.

Check whether the M code output
(power ON signal) of the control device
is pulse or level.
Receiver is set to pulse input as the
factory default settings. In case of
level output, turn on the DIP switch
No.7 of the receiver to set to level input.

Transmitter starts measurement
before switching to Measuring mode.

Turn on the dwell after M code (power
ON signal) switched on.(It takes up to a
second to switch to a measurement
mode after receiving the power ON
signal. In case of poor communication
environment, it might take up to 3
seconds.)

Probe’s power supply is off state .

After confirming that the transmitter is
within the range of movement try sending
M code (power ON signal) again.

Transmitter and receiver
outside signal transmission range.

Check the positional relationship
between the transmitter and receiver
(

refer to P17).

Dead battery

Replace the battery.

Machine stops at
an unexpected
location during
the measurement
cycle.

Defective wireless communication
or transmitter is outside signal
transmission range.

Check the position of the receiver
and remove any obstacles.
