SciTronics Model CS 1000Overview The SciTronics belt scale system is installed on a conveyor andweighs material in transfer. It is designed for such applications asrock crushing plants, asphalt and concrete products batch plants,ore processing plants, coal preparation plants, recycling plants,paper and wood processing plants, food processing plants, andfertilizer plants.The belt scale system consists of the following components:• belt scale assembly with bridge transducer electronics• speed sensor• digital signal processorThe rigid steel construction of the belt scale assembly ensurespermanent alignment with the conveyor. The precision NTEP-approved strain gauge load cell accurately weighs the materialbeing conveyed. The weight signal from the load cell is convertedto a digital computer signal in the bridge transducer signalconditioner and transmitted to the digital signal processor.The speed sensor outputs the speed signal that is proportional tothe velocity of the belt. The signal is converted to a digitalcomputer signal in the bridge transducer signal conditioner andtransmitted to the digital signal processor.The digital signal processor receives the weight and speed signals,performs calculations, and displays values for rate, total weight,and belt speed in selectable standard engineering units (tons,pounds, tonnes, or kilograms). The processor screen display is ahigh-intensity, 4-line by 20-character alphanumeric display that isadjustable to high, medium, or low intensity. The screen-saverfeature automatically turns the display off during inactive periodsto prevent damage to the screen. Using the screen menus andprocessor keypad, the operator easily steps through programmingof the setup data.The multiple scale interface network allows connection of up tofour scales to each digital signal processor.1-2

Section 2 InstallationSection 2 InstallationOverview This section provides instruction for mechanical and electrical installation of the belt scale system.Unpacking the Belt 1. Remove the belt scale assembly and speed sensor from theScale System pallet.2. Place the shipping container containing the digital signal processor on a stable surface and open it, taking care not to damage the contents.3. Inspect the contents and report any shipping damage or missing parts to the carrier as soon as possible (most carriers will not consider a claim unless notified within 15 days of delivery). __________________________________________ NOTE The bill of lading for this shipment is an acknowledgment by the carrier of the receipt of the equipment in good condition. SciTronics is not responsible for any loss or damage incurred during shipment. Note any damaged or missing parts on the carrier’s delivery receipt. Sign the notation and have the carrier’s driver also sign it. The consignee is responsible for initiating claims against the carrier. __________________________________________Installing the Belt __________________________________________Scale System WARNING To prevent bodily injury, be sure that the conveyor is locked out before beginning installation. __________________________________________2-1
SciTronics Model CS 1000 ______________________________________ CAUTION 1. Whenever possible, be sure to install the belt scale on the conveyor in a location where it is protected from the weather. Wind can cause weighing errors. 2. Curvature or upturn in the conveyor is serious. Consult the factory before mounting the scale. ______________________________________Mounting the Processor 1. Select a location close to a 115 V power source that is within 1,000 ft (304.8m) of the scale and where the processor will not be exposed to excessive vibration, heat, and moisture. If mounting the processor outside, be sure to place it in a vandal-proof enclosure.2. Secure the processor to a wall or support at a height where the screen display can be easily seen and the keypad is accessible. Be sure there is sufficient clearance to open the enclosure. Refer to Figure 2-1 for dimensional specifications.2-2
Section 2 InstallationModifying & Mounting The weigh idler (the idler to be mounted to the scale) must bethe Weigh Idler to the modified to fit the scale mounting pads and then mounted to theBelt Scale scale:1. Select an idler identical to the idlers that will be in the weighing section of the conveyor. The idler must be in good condition - the rollers must turn freely and have good concentricity.2. Saw cut or torch cut the existing mounting feet to remove them from the idler.3. Sometimes it is necessary to remove material from the idler that may weaken the roller support. If so, reinforce the end brackets by welding a “gusset” between the vertical end bracket and the horizontal piece.4. Place the idler on the new mounting pads, which are bolted the scale assembly. Center the idler from side to side on the pads. Check for sufficient clearance - approximately ½ in. (13 mm) - between the bottom of the idler and the scale frame.5. Center the idlers exactly 18 in. (457 mm) from the rear pivot support and the center of the end idler rollers, typically to the grease fitting.6. Clamp in place. Check for squareness from corner to corner and check the dimensions. _______________________________________ CAUTION To prevent damage to the load cell, disconnect it and remove it from the housing. _______________________________________7. Weld the idler to the new mounting pads.Mounting the Belt Scale Place the belt scale assembly where a minimum of belt stress orAssembly on the deformation can occur (that is, away from the loading area and theConveyor head pulley). Referring to Figure 2-2, install the belt scale assembly by doing the following:1. Raise the belt clear of the idlers in the weigh section.2. Loosen three idlers on each side of the scale. If your conveyor is very short, reduce the scale section to two idlers on each side. Aligning longer sections can improve performance. 2-3
SciTronics Model CS 10003. Mark the center of each roller.4. Place two 1/8 in. (3mm) shims (a total of ¼ in.) under the feet of both the +3 and -3 idlers.5. Stretch three string lines over the center marks on the +3/-3 idlers. Bolt the idlers down exactly six spaces or weigh spans apart. For example, for a 36 in. (91cm) weigh span, attach the +3/-3 idlers exactly 18 ft (5.49 m) center to center and square with the conveyor.6. Shim the belt scale assembly to obtain 1/32 in (.8mm) clearance below the string line.7. Shim the +1/-1 idlers to 1/32 in (.8mm) clearance. ______________________________________ CAUTION Poor alignment will affect scale accuracy. ______________________________________8. Shim the remaining idlers according to step 7, aligning all center marks. Bolt the idlers down lightly. Check again after tightening the bolts.9. When the belt scale and the idlers are securely attached, remove one of the 1/8 in (3mm) shims from the +3/-3 idlers and reattach the +3/-3 idlers into position. The entire belt scale section is now flat between the +2/-2 idlers and 1/16 in (.8mm) higher than the +3/-3 idlers.2-4
Section 2 Installation_______________________________________CAUTIONTo prevent damage to the load cell, disconnect it andremove it from the housing._______________________________________10. Tack weld ¼ in (6mm) on each idler foot to prevent it from moving out of position. For extra stability and to minimize twisting on portable conveyors, tack weld all idlers.11. Remove the string lines and lower the belt. Run the conveyor and adjust the tension until the belt runs true in the center of the idlers. Check that all the idlers in the scale area turn freely from the pressure of the empty moving belt.Mounting the Bridge Mount the bridge transducer circuit board enclosure between theTransducer Circuit processor and the belt scale so that it is within 6 ft (1.8m) of theBoard Enclosure belt scale assembly.Installing the Speed The “Belt Rider” speed sensor is shipped assembled and ready forSensor installation on the conveyor. For convenience, install the speedsensor just behind the scale in the mounting holes provided. Thefactory provides an adequate length of cable to allow placing thespeed sensor a sufficient distance in front or behind (but not over)any return idlers. If necessary, the speed sensor can be installed infront of the scale if the above guidelines are followed.Install the speed sensor by doing the following: 1. Place the speed sensor on the conveyor stringers. 2. Center the speed sensor wheel on the belt. 3. Square the speed sensor mounting pipe to the conveyor. 4. Mark and drill the mounting holes in the stringers - drill a ¼ in (6mm) clearance hole. 5. Using the ¼ in X 2 in (6mmX51mm) bolts provided, bolt the speed sensor to the conveyor.2-5
SciTronics Model CS 1000Attaching the Load Cell The factory disconnects the load cell before shipping the belt scaleto the Belt Scale assembly. Attach the load cell to the belt scale assembly by doingAssembly the following: 1. Remove the cover panel of the scale. Locate the T-handle Allen wrench and the load cell and remove them. 2. Using the Allen wrench, remove the 3/8 in (10mm) bolt from the belt scale assembly. 3. Insert the bolt into the load cell and attach the load cell to the belt scale assembly using the wrench.Wiring the Belt _______________________________________WARNING Be sure that the power is off before wiring the belt scale system. _______________________________________Consider the following before making electrical connections:• Do not shorten the load cell cable. The wire lengthto load cell temperature compensation.• Do not route the load cell or signal cables in the sameconduit as the power wires or any large source of electricalnoise.• Connect the shields only where shown.• Check that all wires are tight in their connectors - this isespecially important for load cell connections.• Earth ground all enclosures and conduit.Referring to the wiring diagram in Figure 2-3 on page 2-7, wire thebelt scale system: 1.
