1.0 Introduction
The speed sensor monitors the belt speed. It is directly coupled to a rotating shaft (i.e. the bend pulley as shown in Table 2-1 on
page 4) which drives a signal generator. The speed sensor submits an output signal at a frequency directly proportional to the
shaft speed.
It is typically installed on a non-driven pulley of a belt conveyor for detecting belt speed.

1.6 882D Pulse Input
Use J13 connector on the 882D CPU board to provide pulse input from speed sensor to the 882D. Wire the cable to connector
as shown in Figure 1-4. Pins 4, 5 and 6 are top level of the connector and make up the primary pulse input channel (Input 1).
Pins 1, 2 and 3 are bottom level of the connector and make up the secondary pulse input channel (Input 2).

2.0 Installation
Install the speed sensor using the following instructions.
Ensure that the belt scale is turned off and all power to the unit has been removed prior to starting the
installation of the speed sensor.
Figure 2-1. Installation Diagram
1. Locate the center of the bend pulley shaft and punch mark.
2. Drill 1/4'' (6 mm) pilot hole.
3. Use 17/32'' (13.5 mm) bit to drill the center of the pulley shaft (minimum 1'' deep) (26 mm).
4. Tap the drilled hole with 5/8-11 tap (M16x2).
5. Install (thread) the supplied coupling into the tapped hole (may use thread-lock adhesive) and tighten.
6. Use supplied bolts, washers and nuts to connect the anti-rotation arm to the speed sensor.
7. Weld a support plate on the conveyor frame at a suitable position.
8. Place the anti-rotation arm against the support plate.
9. Use the supplied spring to tension the anti-rotation arm against the support plate.
10. Secure to fixed object. Be sure to make the spring in slight tension when connecting the two parts.

Installation

Do not attach the speed sensor on a driven pulley. A driven pulley may have belt slippage in certain conditions, which may reduce
speed sensing accuracy.
The selected bend pulley should have a suitable diameter. The rotary speed of the bend pulley should be kept within the detection
range of the speed sensor.
The bend pulley should have a minimum of 30 degrees belt wrap to ensure positive rotation, because any slippage between the
belt and the pulley may cause reduced accuracy of the belt scale.
2.1 Testing
After installation, test unit to ensure proper mechanical and electrical operations. Make sure cover is tightly secured and conduit
sealed to prevent entry of water or moisture.

3.0 Troubleshooting
• Ensure that the rotary shaft is connected securely to the pulley.
• Ensure the unit is wired correctly and the connections are tight.
• Open the cover of the speed sensor. Ensure that the signal generator works properly.
• If the speed sensor still fails after the above check points have been performed, check the peripheral circuit for fault finding.
Do not try to modify or change the components without prior approval of Rice Lake Weighing Systems. Rice
Lake Weighing Systems will have no liability for any damage caused by the user’s modification even during the
warranty period.
3.1 Spare Parts
Rice Lake Weighing Systems recommends keeping the following spare components on hand for each unit.

used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
Canada
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of Communications.
Le présent appareil numérique n'émet pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de la Class A prescites dans le Règlement sur le brouillage radioélectrique edicté par le ministère des
Communications du Canada.
