the xed blanking function. Be sure to set this function in the state where the
emitter emits light. Furthermore, this function cannot be set in the state where
all beam channels receive lights / are blocked.

Manual setting : Each beam channel can be set to “valid / invalid” in the xed blanking function

respectively.

3-1-4 Muting Setting Changing Function

The setting of the muting function can be changed.

Setting of the muting function on each beam channel

Each beam channel can be set to “valid / invalid” in the muting function respectively. (Note)
All beam channel can not be all invalid.
The factory setting of this function is valid for all beam channels.

Note: If the beam channel set to invalid in the muting function is blocked, the control output (OSSD 1 / 2) becomes “OFF” and the

muting function is canceled.

There are two setting methods, “Auto” and “Manual” to set muting beam channel.

Auto setting : The beam channel which is currently blocked is set as the “valid” beam chan-

•
nel. When all beam channels are in light receiving condition, the setting is not
accepted. Furthermore, in the state that all beam channels are blocked, the all
beam channels become “valid” in the muting function.

Manual setting : Each beam channel can be set to “valid / invalid” in the muting function.

•
ON: The muting function is valid
OFF: The muting function is invalid

Muting maximum continuous valid time setting

Maximum continuous valid time setting for muting function can be changed.

Combination of using muting input conditions and setting of each beam channel of the muting
function allows to set making muting function valid when muting input conditions are 1 to 2 or 2
to 1.
The setting method is to set the each beam channel setting of muting input condition 1 to 2 and
set the each beam channel setting of muting input condition 2 to 1.

Functional Descriptions

When using the device in PNP output (or NPN output), use PNP output (or NPN output)
safety sensor. The control output (OSSD 1 / 2) becomes OFF by using wrong output type
of sensor.
Series connection is also available when connecting other
put 1 / 2. However, this device does not incorporate the interference prevention function.
Thus, take suf cient care when installing the devices.
Use a safety sensor which incorporates a crossover short-circuit function in the control
output and connect both the safety input 1 wire (gray) and the safety input 2 wire (gray /
black). Take care that if only one wire is connected, the device may not operate normally.
Use a safety contacting point which incorporates two NC (Normally Closed) contacting
points and connect both the safety input 1 wire (gray) and the safety input 2 wire (gray /
black). Take care that if only one wire is connected, the device may not operate normally.
In case setting the safety contacting point input mode or the safety sensor input mode,
