When the sensor head
FSU-

-

is supplied, the sensor head body and
mini clamp connector (male) are not yet connected. Follow the procedure
below to perform the connection.
1.
Check that the connector cover (the part where lead wires are to be
inserted) is protruding from the connector body.
It cannot be used if it’s flat and placed at the same level against the body.
2.
Cut the cable at the length required for the sensor head. Strip off the cable
sheath for 50 mm [1.97 in.] from the cable end, and expose the lead
wires. At this time, do not take off the lead wire insulation.
3.
Follow the instructions in the table below to insert the lead wires into the
hole in the connector cover. Look through the top of the semi-transparent
cover to check that the lead wires have been firmly inserted all the way to
the back. (Insertion length is about 9 mm [0.35 in.].)
Use caution in making the connections, since switching on the power with
wrong connections will damage the sensor head and controller.
4.
Taking care to avoid letting the lead wires slip out from the connector, use
pliers or some other hand tool to crimp the cover and connector body,
and push the cover into the connector body.
Limit the crimping force to 980.7 N [220.5 lbf.].
When the cover is flat and placed at the same level against the connector
body, the connection is complete.
5.
In the same way, handle the sensor head relay cable

connectors (male, female).
6.
Check one more time that the wiring is correct.
Sensor head and connector connection procedure
To mount the sensor head and the power supply, switch, and communication
cable, align the lock lever position as shown in the figure, and push until the
lock hooks on the controller-side connector.
To remove, push down completely on the lock lever, take the connector and
pull it out. At this time, be careful to avoid applying excessive force on the
lead wires.
