Introduction
The CCSS0001 forklift scale is designed for mounting on Cat® Lift Trucks. It is a fully electronic scale with a capacity of 5,000 lb (2,000 kg). The scale consists of two components: (1) a scale carriage, which is installed in place of the forklift truck’s lift bracket, and (2) a scale controller, which is mounted on the forklift truck’s head guard. The scale carriage and controller communicate by radio, so there are no wiring connections between them to limit the movement of the forks.
Figure 1-1: Forklift Scale Carriage
This manual explains how to install, operate, and service the CCSS0001 forklift scale. If any information in the manual is incorrect or missing, please use the Publication Suggestion Report at the back of the manual to tell us about it.

Remove the Forklift Truck’s Lift Bracket
1.
Park the forklift truck on a level surface, and make sure the mast is in the vertical position.
2.
Remove both of the forks.
3.
If the forklift truck is equipped with a load backrest extension, remove the load backrest extension.
4.
Raise the mast so that the lift bracket is at a comfortable working height (3 or 4 feet off the ground).
5.
Wrap a sling securely around the lift bracket’s upper fork bar.
6.
Attach the sling to a crane (or other lifting device with a capacity of at least 500 lb), and use the crane to raise the lift bracket so that the chains have some slack in them.
CAUTION
BE SURE TO BLOCK THE LIFT BRACKET WHEN IT IS IN THE RAISED POSITION. OBSERVE ALL APPROPRIATE SAFETY PROCEDURES WHEN INSTALLING AND SERVICING THE SCALE.
7.
Disconnect the two chain anchors from the mast by removing the lower jam nut from each anchor (see Figure 2-2). Keep the nuts with the chain anchor to use them for installing the scale carriage.

Remove the chains from the pulleys at the top of the mast. Then position the chains over the front of the lift bracket so that they will not interfere with removing the lift bracket from the mast.
Chapter 2: Installation
Remove the Forklift Truck’s Lift Bracket
9.
Raise the bottom of the inner mast at least 2 feet off the floor to allow enough room to remove the lift bracket from the bottom of the mast.
10.
Use the crane to lower the lift bracket to the floor and remove it from the bottom of the mast.
11.
Place the lift bracket on a stable working surface, with the front side of the lift bracket facing downward to provide easy access to the rollers and chain mounts.
12.
Disconnect the two chains from the lift bracket. Remove the cotter pin from the master link that is connected to the 90° joint in each chain (see Figure 2-3). Then take apart the master link, using a C-clamp or similar device to press the master link through the link plates. Do not use a hammer or other tool to strike the master link. It could damage the link. Keep the chains and master links to install on the scale carriage.

Install the Scale Carriage

Chapter 2: Installation
Install the Scale Carriage
1.
Park the forklift truck on a level surface, and make sure the mast is in the vertical position.
2.
Place the scale carriage on a stable working surface, with the front side of the carriage facing downward to provide easy access to the rollers and chain load cells.
3.
Install the two lower main rollers by sliding them onto the roller shafts at the bottom of each side of the scale carriage (see Figure 2-6). Be sure to install any shims that were removed from the forklift truck’s lift bracket.
4.
Install the other four main rollers on the scale carriage, securing them with the bolts that were removed from the lift bracket (see Figure 2-6).
Figure 2-6: Install Main Rollers
5.
Mount the two side roller assemblies (including shims) on the scale carriage (see Figure 2-7). Do not use the bolts that were removed from the lift bracket. Instead, use the studs and nuts provided with the scale carriage. Align the two holes in each side roller assembly with the holes located midway between the two bolted rollers on each side of the carriage. Insert the studs in the holes and screw them into the assembly. Then place the washers and nuts on the ends of the studs and tighten them against the carriage.

6.
Use a master link to connect each chain to one of the chain load cells on the scale carriage. Assemble the master link as shown in Figure 2-8. Using a C-clamp or similar device, press the master link assembly together just enough so that you can insert the cotter pin in the holes. If the link is too tight, it can bind against the load cell and chain mount. If the link does not rotate freely on the load cell or chain, press the master link back through the link plates until it rotates freely.
NOTE: When a forklift scale is installed, a standard chain should have 35 links (including master links). Add or remove links if necessary.

Position the chains over the front of the carriage so that they will not interfere when you install the carriage in the forklift mast.
8.
Raise the bottom of the inner mast at least 2 feet off the floor to allow enough room to install the carriage from the bottom of the mast.
9.
Wrap a sling securely around the upper part of the scale carriage.
Chapter 2: Installation
Install the Scale Carriage
10.
Attach the sling to a crane (or other lifting device with a capacity of at least 500 lb), and use the crane to lift the scale carriage. Position the carriage so that its main rollers fit into the bottom of the mast channel. The chain load cells are located on the back side of the scale carriage.
11.
Raise the carriage to a comfortable working position, keeping the main rollers aligned inside the mast channel. Move the carriage up and down several times to make sure that it moves freely within the mast. If the carriage fits too tightly within the mast, you might need to remove shims from the bottom rollers or side rollers.
12.
Position two blocks of wood (3 inches high) on the floor under the carriage’s lower fork bar. Lower the inner mast and carriage until the fork bar rests on the blocks.
13.
Route the chains over the pulleys at the top of the mast.
14.
Remove the lower nut from each chain anchor and insert the anchor into the hole in the mast, below and behind the chain pulleys. Place the lower nut on the threaded anchor and tighten it until both it and the upper nut are tight against the mast (see Figure 2-9). You will need to adjust the anchors later, so do not tighten the nuts too much. Make sure there is no slack in the chains, so that the carriage does not drop when you remove the sling.

15.
Remove the sling from the scale carriage.
16.
Raise the carriage slightly. Put the forks back on the lift truck, positioning a fork at the next to last notch on each side of the carriage.
17.
Lower the carriage to the floor so that the stages of the mast are completely collapsed.
18.
Adjust the chain anchors so that each chain has 3/4 inch of slack. This will allow room for the chains to adjust when the mast is set at an angle. With the mast in the vertical position and the carriage fully lowered, the distance between the floor and the bottom of the scale carriage should be 76 to 80 mm (about 3 inches).
19.
After installing the scale controller and scale carriage, place a pallet on the forks and exercise the scale to make sure that all components seat properly. Repeatedly place a test weight on the scale, positioning it on the center of the scale and at each corner of the scale.

METTLER TOLEDO Model CCSS0001 Forklift Scale Technical Manual

Batteries

A 12-volt battery pack is used to power the scale’s load cells and carriage radio. The scale is supplied with two batteries and a battery charger. New batteries must be charged before they can be used. A fully charged battery will allow you to operate the scale for up to 36 hours. The battery level indicator on the scale controller’s main weighing screen alerts the driver when the battery’s voltage level is low.
• To install a battery, insert it in the scale carriage’s battery compartment. Position the
battery so that the metal contacts on its side fit against the metal contacts in the battery compartment.
• To remove a battery, press the plastic tab toward the center of the battery and pull
the battery out of the battery compartment.
• To charge a battery, insert it in the battery charger (see Figure 2-10). Then plug the
battery charger into a standard electrical outlet (110 volts). It will take 12 to 16 hours to provide the initial charge for a new battery. Once a battery has been used, it should take no more than 3 to 4 hours to recharge it. A red light on the battery charger indicates that the battery is being charged. A green light indicates that the battery is fully charged. When a battery is fully charged, the charger goes into trickle mode, so there is no danger of damaging a battery by overcharging it.

Geo Index

Chapter 2: Installation
Geo Index
To compensate for local gravitational forces, change the geo index to the setting for the location where the scale will be used. The factory default setting is 16 (the geo index for Worthington, Ohio, USA). To determine the geo index for a location, refer to the appendix (Chapter 9). You must know the geographical coordinate for the location and the elevation above sea level.
1.
To change the geo index, enter the scale controller’s setup mode by touching the
Setup button on the main weighing screen.
2.
Touch the Scale button, touch the Calibration button, and then touch the Where Used button.
3.
A keypad is used to enter the geo index. Type a number in the data field by touching the numeric keys on the keypad (the range is 0 to 31). Touch the Clear button if you wish to clear the data field and start over.
4.
Touch the Enter button to confirm your selection or the Cancel button to cancel any changes that you made.

Shift Adjustment

Forklift scales are calibrated at the factory and should not need to be recalibrated when they are installed. You should, however, check the scale after installing it to see if it needs to be shift adjusted. A correctly adjusted scale will give you the same weight reading no matter where on the forks you place a test weight. If the weight readings at the shift test locations are out of tolerance, shift adjust the scale to correct the problem.
Park the forklift truck on a level surface, place a pallet on the forks, raise the forks 12 to 15 inches off the ground, set the mast to the vertical position, and shut off the forklift truck’s motor. Then check the scale’s repeatability by placing a test weight on the same location on the pallet several times to make sure that you get the same weight reading each time.
After verifying the scale’s repeatability, check to see if the scale needs to be shift adjusted. For shift adjustments, we recommend using test weights equal to one half the scale’s maximum weighing capacity. The test weights must meet the specified National Institute of Standards and Technology Handbook 44 accuracy requirements.
NOTE: When performing a shift adjustment, use the weight readings on the data screen instead of those on the main weighing screen. The weight readings on the data screen are displayed to two decimal places, although the number in the second decimal place might not be stable.

Shift Test Locations
Place a pallet or other flat surface (approximately 4 feet by 4 feet) on the forks and make sure that it is level. Figure 2-11 shows test weight locations (1, 2, 3, and 4) at the center of each quadrant of the pallet. Place the test weight at location 1 and record the weight reading. Then move the test weight to location 2 and record the weight reading. Continue until you have taken a weight reading at each of the four locations.

Figure 2-11: Shift Adjustment Locations
Ideally, the scale will give you the same weight reading at all four locations. The weight readings at the heel and toe of either or both forks should be within Handbook 44 tolerance requirements (±2.5 lb for weights up to 2,500 lb). If the weight readings are out of tolerance, you will need to shift adjust the scale. This is done by adding shims to the flexures at the locations shown in Figure 2-11. To determine where to add shims, refer to Table 2-1.

Table 2-1: Shim Locations
The shims adjust the differences between the weight readings at the heel and toe of an individual fork. Adjust the weight readings so that they are as near to equal as possible. If one weight reading is slightly higher, it should be the reading at the toe of the fork.
Shimming at the front of a flexure (location A) will increase the weight reading at the toe of the fork (location 2). Because the shim affects the entire fork, it will also slightly increase the weight reading at the heel (location 1).
Shimming at the back of a flexure (location B) will decrease the weight reading at the toe of the fork (location 2). Because the shim affects the entire fork, it will also slightly decrease the weight reading at the heel (location 1).
A pallet places load on both forks. So when a pallet is used, shimming under a flexure will affect the readings at all four test weight locations. For example, shimming at
Chapter 2: Installation
Shift Adjustment
location A or B will change the readings at locations 1 and 2, but it will also change the readings at locations 3 and 4 to a lesser extent.
Keep in mind that, in addition to balancing the weight readings at the heel and toe of each fork, you are also trying to balance the weight readings of the two forks.
Shimming Procedure
Do not remove the bolts from more than one flexure at a time. The flexures connect the two sections of the scale carriage. If you unbolt the two top or bottom flexures, the sections of the carriage could separate and cause injury or damage the flexures.
DANGER
DO NOT REMOVE THE BOLTS FROM MORE THAN ONE FLEXURE AT A TIME WHILE THE CARRIAGE IS INSTALLED ON THE FORKLIFT. UNBOLTING MORE THAN ONE FLEXURE COULD RESULT IN BODILY HARM OR PROPERTY DAMAGE.
1.
Remove the bolts from the side of the flexure where shims will be added.
2.
Loosen the bolts on the opposite side of the flexure.
3.
Place a shim under the flexure, aligning the bolt holes in the shim with those in the flexure. We recommend starting with the thinnest shim and gradually increasing the shim thickness as needed to balance the weight readings.
4.
Replace the bolts that were removed, and tighten all bolts (torque to 90 ft-lb).
5.
Repeat steps 1-4 for the second flexure if needed.
6.
Take new weight readings at all four test weight locations. If the weight readings are still not equal, repeat the procedure to add additional shimming.
7.
When you have finished shift adjusting the scale, you should get approximately the same weight reading at all four test weight locations.

Push Buttons

The push buttons at the bottom of the main weighing screen are used to perform weighing functions and to enter setup mode.
Zero
The Zero button is used to zero the scale manually. This feature can be used if the weight reading on the screen does not return to zero when all load has been removed from the scale. In order for this button to zero the scale manually, (1) the scale must be in gross weighing mode and (2) the weight reading on the screen must be within the range specified in the manual range setup feature. The scale also includes an automatic zero maintenance (AZM) feature. When AZM is enabled, the scale will be zeroed automatically if the weight reading is within a specified range.
Tare
The Tare button is used to assign the weight that is currently on the scale as a tare weight. The tare weight is the weight of an empty pallet or container. It is subtracted from the gross weight (weight of the loaded pallet or container) to determine the net weight (weight of the item on the pallet or the material in the container). The tare weight will be displayed in the Tare field. This button will work only if push button tare is enabled in scale setup.
Clear
The Clear button is used to remove a tare weight reading or accumulated weight reading that is displayed on the screen. To remove a tare weight reading, touch the Clear button and then touch the Tare button. To remove an accumulated weight reading, touch the Clear button and then touch the Accum button.
Accumulator
The Accum button is used to accumulate a series of weights and sum them to calculate a total weight. When you touch the Accum button, the gross or net weight that is displayed on the screen will be added to the weight reading in the Accumulated Weight field. This button will be available only if basic accumulate is enabled in application setup.
Gross/Net
The Gross/Net button is used to switch between gross and net weight readings on the screen. In order to switch to a net weight reading, you must first assign a tare weight. This button will work only if gross/net switching is enabled in scale setup.
>>
The double arrow button is used to display additional push buttons on the screen.
Setup
The Setup button is used to enter setup mode on the controller. For an explanation of the setup features and how to use them, refer to the “Scale Setup” section of this manual.

(2/04)
Keyboard Tare
The Keybd Tare button is used to enter a tare weight manually. The tare weight is the weight of an empty pallet or container. It is subtracted from the gross weight (weight of the loaded pallet or container) to determine the net weight (weight of the item on the pallet or the material in the container). When you touch the Keybd Tare button, a keypad will appear on the screen. Type the tare weight by touching the numerical keys on the keypad. Then touch the Enter button. The tare weight will be displayed in the Tare field. This button will work only if keyboard tare is enabled in scale setup.
