ADJUSTMENTS AND SETTINGS
Sensor Frame The sensor frame can be height adjusted, this optimizes the reading capability
of the sensors. Setting the height as shown is good for all sensor types.
Frame Height
Setting
The mounting brackets are secured in the ‘T’ slots of the sensor frame and onto
the conveyor rails. The height of the frame should be set to the dimension shown
(128mm from the top of the conveyor belt to the top of the frame section). The
smaller bracket at the rear of the mounting bracket (Frame Height Setting
Bracket) maintains this height adjustment, it is set by sliding it in its slot up to
the underside of the sensor frame where it is locked. Once set, the brackets may
be moved to a new location (e.g., where rail width needs adjusting) without the
need to reset the height. Once the height has been set, the correct focus for the
sensors is maintained

Configuring the Sensor Frame for the Upline Conveyor
The sensor frame is supplied to the customer requirements. If the process is
altered e.g., the printing machine is repositioned and the input conveyor is
changed-over, then the sensor positions need to be ‘mirrored’ on the frame.
To reconfigure the frame for use on the opposite input conveyor, the sensors all
need to be ‘mirrored’.
1. The clamp handles can be lifted against a spring and repositioned.
2. Remove the centre rail. Slacken the handles at both ends and slide the rail
out of the clamps.
3. Rotate the rail by 180
0
so that the bar code reader is facing in the opposite
direction. Refit the rail.
4. Remove the tie wrap and reverse the cable loop so that the reader can be
positioned along the rail. Re tie wrap to secure the cable.
5. Remove the rail with the ‘Board Present Sensor’ fitted. Rotate it and move it
to the opposite side of the centre rail, feed the cable under the centre rail, refit
the rail.
6. Relay the cables in the tray so that the cables do not bind and they allow
freedom of movement.
7. If the ‘Product Sensor’ option is fitted then complete Step 3 the same as for
the bar code option.

Fitting the Frame
to the Conveyor
If the frame has been moved from its original position to the opposite input
conveyor, it needs to be fitted to the input conveyor framework.
1. Slacken the top two screws holding the rear brackets.
2. Place the frame on the conveyor with the front brackets resting on the front
conveyor rail.
3. Roughly position the rear corner brackets so that they rest on the rear
conveyor rail. Make sure that the corner brackets do not interfere with board
transport.
4. Position the frame left to right such that the ‘Board Present Sensor’ is
roughly aligned with the conveyor sensor.
5. Fit the screws and nuts to loosely hold the four corner brackets to the
conveyor ‘T’ slots
6. Check the frame to conveyor height setting - 128 mm from the top of the
frame to the top of the conveyor belt. If necessary slacken off the lower two
screws on each of the corner brackets (Step 1 shows the top two screws only,
slackened off) and adjust as necessary
7. Fit the cables from the rear service panel to the frame. Bar code reader
connects to 6SK17 the ‘Board Present Sensor’ connects to 6SK21 while the
‘Product Sensor’ connects to 6SK20. Tie wrap the cables to secure.
