Connection of a Variety of Sensors Section 3-4
Note If the optical fiber cables are disconnected without setting the fiber lock lever
to FREE, the optical fiber cables may break and the E3X-MA11 may malfunc-
tion due to fragments of broken optical fiber cables.
Cutting Fiber • Insert a 2.2-mm-dia. fiber into an E39-F4 Fiber Cutter and determine the
length of the fiber to be cut.
• Press down the Fiber Cutter in a single stroke to cut the fiber.
• When the fiber is cut, insertion marks are inscribed on the fiber. The por-
tion from the tip up to the insertion marks should be inserted into the E3X-
MA11.
• To correctly inscribe the insertion mark, place the length of the fiber into
the Fiber Cutter in direction 1 as illustrated below, and press down firmly
in direction 2.
• The cutting holes cannot be used twice. If the same hole is used twice,
the cutting face of the fiber will be rough and the sensing distance will be
reduced. Always use an unused hole.
Use either one of the two rightmost holes to cut a thin fiber as follows:
1,2,3... 1. An attachment is temporarily fitted to each thin fiber before shipment.
2. Secure the attachment after adjusting the position of it in the direction in-
dicated by the arrow.
3. Insert the fiber into the E39-F4 and cut.
