Mounting Units
Catch the hook on the Sensor Head connector end
of the Unit on the DIN Track and then press down
on the other end of the Unit until it locks into place.
Always attach the Sensor Head connector end first.
If the incorrect end is attached first, the mounting
strength will be reduced.
●
Removing Units
Press the Unit in the direction indicated by "1"
and then lift up on the Sensor Head connector
end of the Unit in the direction indicated by "2"

Mounting Amplifier Units in Group (Connector Type Models/Communication Unit
Connection Type Models)
Up to 16 connector type models can be connected. Up to 30 communication unit
connection type models can be connected to the communication unit
E3X-ECT, or 16 units to the E3X-CRT.
1. Mount the Amplifier Units one at a time onto the DIN Track.
2. Slide the Amplifier Units together and press the Amplifier
Units together until they click into place.
Secure the Units with an End Plate (PFP-M) if there is a
possibility of the Amplifier Units moving, e.g., due to vibration.
Reverse the above procedure to separate and remove the
Units. Do not attempt to remove Amplifier Units from the
DIN Track without separating them first.

The function of the output for channel 2 can be selected.
This setting is not value if DIFF (differential operation)
is set for the detection method. (The output for channel
2 is always an alarm output for differential operation.)
Self-diagnosis output
Output when the detection level
is not stable, i.e., when the detection
level is ±10% of the threshold value
for 300 ms or longer.
Disconnection output
A disconnection output is outputted,
when the Sensor Head is
disconnected, or it does not connect.
Automatic teaching
The maximum and minimum detection
levels are sampled while the input is ON and,
when the input turns OFF, the average of these
values is set as the threshold value.
Disabled if the detection function is set to
"DIFF" (differential operation).
The information displayed in RUN mode can be selected.
When going to SET mode, this setting will be ignored and
the detection level and threshold value will be displayed.

Whether external input execution results are written
to EEPROM can be selected.
Disable this function if the external input is turned
ON frequently. (The write life is approximately 100,000
writes.)
Hold down the MODE key and
press the UP key for at least 3
