Sensors

NOTE:

avoid unwanted trigger signals, make sure that there are

objects other than the substrate

that

pass between the emitter and

receiver during line operation.

Also, make sure that the emitter and

receiver are mounted no more than

10ft

(3 m) from each other.

1. Check the intended mounting position to ensure that there is enough

space to mount the sensor(s} and bracket(s}.

See Figure 3.11,

Figure 3.

, and Figure 3.13

2. Check the intended mounting position to make sure that there are no

objects other than the substrate that

will pass between the sensor

and substrate during

line operation.

3. Locate the emitter bracket

that the emitter is no further than 1 0 ft

(304.8 em) from the substrate.

4. Securely connect the emitter bracket to the mounting surface.

Excessive movement or vibration can

result in intermittent or false

operation caused by loss

alignment to the substrate.

Securely connect the receiver bracket to the mounting surface.

6. Using the two mounting

lts provided with the bracket

secure the

emitter and receiver to their respective brackets (Figure 3.13).

7. Route the sensor

leads through water-tight conduit (for an

-54

enclosure

rating) and the strain relief connector and into the PC40.

8. Skip to "Nordson Photosensor Wiring Connections."
