TROUGHING SMART ROLL DIAGRAM AND PARTS LIST:
See Troughing Smart Roll Part Numbers in section A6 .
RETURN SMART ROLL MOUNTING INSTRUCTIONS:
Attention must be given to the location of the Smart Roll so that it is always in contact with the belt . Failure to mount properly may void
warranty and could cause damage to conveyor belt and other components .
NOTE: Care must be taken to avoid scraped, pinched, or crushed wiring . Wires that are scraped, pinched, or crushed during shipping,
handling or installation will void the warranty .
1 . Identify the Smart Roll as a Return Smart Roll and select the mounting site on the conveyor . The Return Smart Roll is designed to be
placed on the return belt side of the conveyor in PPI D drop brackets (not included) .
2 Determine which side of the conveyor is desirable for running the conduit/wires for the Smart Roll . It is advisable to route the wires/
conduit for the Smart Roll away from electrical power conduit as the electrical power may cause electromagnetic interference (EMI) in
the signal from the Smart Roll . If EMI is present the signal from the Smart Roll may not make it to the Smart Monitor or PLC . This will
result in the Smart Monitor or PLC getting faulty readings .
3 . If existing PPI drop brackets are in place loosen the bolts holding the drop brackets to the conveyor structure . If existing drop brackets
will not work install new PPI drop brackets loosely .
4 . Unscrew the hex bushing from the wired end of the Smart Roll and carefully slide it over the wiring and set aside to be replaced later .
5 . Wired end of the Smart Roll: Run the wires from the Smart Roll through the drop bracket on the side the conduit will run . Place the
Smart Roll end into the drop bracket so the Smart Roll is held in the drop bracket by the flats on the shaft . Ensure that the Smart Roll
wiring will not be crimped, scraped, pinched or crushed when installing the Smart Roll . Slide the wiring through the end clip and over
the shaft and lock the Smart Roll into the drop bracket using this end clip with the self-tapping screw . Slide the wiring through the hex
bushing previously removed and thread it onto the shaft .
6 . Place the non-wired end of the Smart Roll in the other drop bracket so the roll is held in place by the flats on the shaft and the drop
bracket slot . Lock this end of the Smart Roll into the drop bracket using the D end clip and self-tapping screw .
7 . Align the Smart Roll so it is square and horizontal with the centerline of the conveyor frame . Tighten bolts on the drop brackets to the
conveyor frame .
RETURN SMART ROLL WIRING:
1 . Disconnect and lockout power before starting wiring procedure .
The Smart Roll is provided with a ½ inch 90° elbow conduit access port . The Smart Roll cable is a 2 wire, 22 AWG, PVC jacket, PVC
insulation, and 6 feet in length . No set-up is required to the sensor inside the Smart Roll . It is factory set and maintenance free .
DO NOT apply voltage directly across the wires of the Smart Roll Sensor, permanent damage may result . The Smart Roll is designed to be
used with a Smart Monitor, PLC or similar device .
DO NOT use an incandescent light bulb as a load . An overload will occur due to extremely high cold current .
DO NOT operate without a load . A dead short will result which may cause irreparable damage .
DO NOT directly operate a motor with the sensor . Always use a relay or other appropriate device .
2 . At this point a 2 wire cable needs to be routed from the control box housing the Smart Monitor to the Smart Roll . It is recommended to
use minimum of 22 AWG shielded cable . Shielded cable eliminates electromagnetic interference (EMI) .
It is advisable to route the wires/
conduit for the Smart Roll away from electrical power conduit as the electrical power may cause electromagnetic interference (EMI) in the
signal from the Smart Roll. If EMI is present the signal from the Smart Roll may not make it to the Smart Monitor or PLC. This will result in
the Smart Monitor or PLC getting faulty readings.
Conduit from the control box to the Smart Roll offers more protection to the cable . Any nick, gouge or cut in the cable wiring could
prevent the sensor signal from reaching the Smart Monitor .
PPI is not capable of being aware of all site and industry electrical requirements for an application, and cannot be held liable for
non-compliant installations. The product has been designed to be capable of meeting many requirements, and a qualified individual should
review the connection plan prior to installation. Connection of conduit to 90° elbow conduit access port does not meet intrinsically safe
requirements.
DO NOT PULL THE WIRES CONNECTED TO THE SMART ROLL. Pulling wire from inside the roll will cause damage and void warranty. Be
sure to protect the wire near elbow threads and all corners, as this may damage the wire/insulation.
