TROUGHING 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 Troughing Smart Roll and select the mounting site on the conveyor . The Troughing Smart Roll is
designed to be placed in the wing roll position of a PPI CEMA C or D 20°, 35°, or 45° Equal Roll troughing frame .
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 . Remove the wing roll from the troughing idler on the side the wires/conduit will be run . Keep the end clip, screw, and the center
clip .
4 . Place the Smart Roll in the troughing idler with the wiring end in the end bracket and the non-wired end in the center bracket . Take
care that the wiring is not crushed . Ensure that the slots on the Smart Roll shaft are turned in the correct orientation to allow the
Smart Roll to drop fully into the brackets .
5 . Replace the center clip in the center bracket .
6 . 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 .
7 . Slide the wires through the largest hole of the end clip and lock this end of the Smart Roll into the end bracket using the end clip
and the self-tapping screw .
8 . Slide the hex bushing previously removed over the wiring and thread it onto the shaft .
TROUGHING 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 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
