SciTronics Model CS 1000
Overview The SciTronics belt scale system is installed on a conveyor and
weighs material in transfer. It is designed for such applications as
rock crushing plants, asphalt and concrete products batch plants,
ore processing plants, coal preparation plants, recycling plants,
paper and wood processing plants, food processing plants, and
fertilizer plants.
The belt scale system consists of the following components:
• belt scale assembly with bridge transducer electronics
• speed sensor
• digital signal processor
The rigid steel construction of the belt scale assembly ensures
permanent alignment with the conveyor. The precision NTEP-
approved strain gauge load cell accurately weighs the material
being conveyed. The weight signal from the load cell is converted
to a digital computer signal in the bridge transducer signal
conditioner and transmitted to the digital signal processor.
The speed sensor outputs the speed signal that is proportional to
the velocity of the belt. The signal is converted to a digital
computer signal in the bridge transducer signal conditioner and
transmitted 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 a
high-intensity, 4-line by 20-character alphanumeric display that is
adjustable to high, medium, or low intensity. The screen-saver
feature automatically turns the display off during inactive periods
to prevent damage to the screen. Using the screen menus and
processor keypad, the operator easily steps through programming
of the setup data.
The multiple scale interface network allows connection of up to
four scales to each digital signal processor.

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 Installation
Modifying & Mounting The weigh idler (the idler to be mounted to the scale) must be
the Weigh Idler to the modified to fit the scale mounting pads and then mounted to the
Belt 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 or
Assembly on the deformation can occur (that is, away from the loading area and the
Conveyor 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 1000
3. 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.

Section 2 Installation
_______________________________________
CAUTION
To prevent damage to the load cell, disconnect it and
remove 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 the
Transducer Circuit processor and the belt scale so that it is within 6 ft (1.8m) of the
Board Enclosure belt scale assembly.
Installing the Speed The “Belt Rider” speed sensor is shipped assembled and ready for
Sensor installation on the conveyor. For convenience, install the speed
sensor just behind the scale in the mounting holes provided. The
factory provides an adequate length of cable to allow placing the
speed sensor a sufficient distance in front or behind (but not over)
any return idlers. If necessary, the speed sensor can be installed in
front 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.

SciTronics Model CS 1000
Attaching the Load Cell The factory disconnects the load cell before shipping the belt scale
to the Belt Scale assembly. Attach the load cell to the belt scale assembly by doing
Assembly 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.

NOTE
The procedure for Initial Programming is organized
so that the operator can access the first submenu in the
Main Menu and continue in order through each
submenu until all data has been programmed.
_______________________________________
Program each submenu as appropriate for your application:
SCALE SET UP SUBMENU
In the scale set up submenu, the operator enters belt scale system
parameters that will be used by the processor in its internal
calculations during calibration and normal operation.
To program the scale set up submenu:
1. At the Main Menu, press the ENTER key. The scale set up
submenu appears on the screen displaying Mode 1: weigh
span. The weigh span of the belt scale is the exact on-
center distance between the first advance and the first
retreat idler from the scale carriage, divided by two. Enter
this value (00.000 to 99.999) into the weigh span field
using the SELECT key to move to each digit and the
INCR and DECR keys to scroll through the numbers until
the appropriate value appears in the field. Press the PROG
key to move to Mode 2.

(0000.00 to 9999.99) into the belt length field using the
SELECT key to move to each digit and the INCR and DECR
keys to scroll through the numbers until the appropriate value
appears in the field. Press the PROG key to move to Mode 3.
3. Mode 3: rate span adjustment appears on the screen. Rate
span adjustment is the value used by the processor during
calibration to manually adjust the scale system. This field has
been set by the factory but it can be changed as necessary. It
may be necessary to change this field during the calibration
process. Enter this value (0000.00 to 9999.99) into the rate
span adjustment field using the SELECT key to move to
each digit and the INCR and DECR keys to scroll through the
numbers until the appropriate value appears in the field. Press
the PROG key to move to Mode 4.
4. Mode 4: azt set point appears on the screen. When the rate
falls below the value set in this field, the processor starts to
track for the length of time indicated in the tracking and auto
zero time interval fields. Do not enter a value above the
lowest normal material flow rate. Setting this field at 00.00
disables auto zero tracking. Enter a value (00.00 to 99.99)
into the azt set point field using the SLELECT key to move to
