CS750, Users Rev R, May 2009 Weights and Measures The CS750 meets or exceeds class III standards for 3000 division accuracy from 300 lb to 1000 lb. The certification was completed by the National Type Evaluation Program (NTEP)s in accordance with the National Institute of Standards and Technology (NIST) Handbook 44. A NTEP Certificate of Conformance Number 96-135 was issued under the National Conference of Weights and Measures.
CS750, Users Rev R, May 2009 Operations Operating Practices Warning: The crane scale will be operated by qualified designated persons, trainees under the direct supervision of designated persons, maintenance and test personnel when in performance of their assigned duties, or lifting device inspectors. Warning: Do not exceed the rated load limit of the crane scale. Warning: The crane scale shall be applied to the load in accordance with the instruction manual.
CS750, Users Rev R, May 2009 Warning: Stay clear of suspended loads. Warning: Do not lift loads higher than necessary. Warning: Do not make alterations or modifications to the crane scale. Warning: Ensure all portions of the human body are kept clear of all device involved with the rigging during the lift.
CS750, Users Rev R, May 2009 ON Press this button to turn the scale on. The scale tests itself; when these tests have completed successfully, the system begins weighing. Note: If you used the remote control to turn off the scale (the last time), you must first press the OFF key, then press the ON key. OFF Press this button to turn the scale off. ZERO Tells the scale to display a zero weight. This button is used any time the scale shows a non-zero value with no weight on the hook.
CS750, Users Rev R, May 2009 Remote Control The circled keys on the diagram below are active for the CS750 crane scale. Notes: Need to press twice to turn on. The ON key on the scale must be pressed to initially turn on the CS750.
CS750, Users Rev R, May 2009 Operation Use Periodic Maintenance Power/Batteries Replacement On the right side panel, remove the two screws that hold the back plate secure. Slide this plate out to access the batteries inside. Change the cells, being careful to note battery orientation. You may use 6 rechargeable Nickel-Cadmium “D” cells or 6 standard “D” cells in the CS750. Warning: Do not plug the charger in while there are standard “D” cells inside.
CS750, Users Rev R, May 2009 Maintenance Periodic Inspection The crane scale and all associated adaptive devices require periodic inspection and maintenance. The frequency and recording of the inspection requirements are found in service categories below and are dependant on the type of service that the equipment is used in as described below. Service Categories Normal Service – Crane scale is operated at less than 85% of it’s capacity except for isolated instances.
CS750, Users Rev R, May 2009 3. Inspect for excessive wear of linkages and other mechanical parts. 4. Inspect for excessive wear at hoist hooking points and load support clevices or pins. 5. Inspect for any visible bends or twists of all used rigging devices. 6.
CS750, Users Rev R, May 2009 Calibration How to test the calibration This calibration procedure should be performed annually for normal operating conditions. If the scale is dropped or damaged, or service has been performed on the scale, use this calibration check. Recommend calibration points at 10% intervals from 10% through 100% of the scales capacity. 1. Press the ON switch. The display does a lamp test; during this time the scale does a quick check of itself.
CS750, Users Rev R, May 2009 Calibration switch The calibration of the scale is protected from accidental change by a switch just inside the right side panel. Enabling the Calibration switch Using a screwdriver, remove the right side plate and move the switch to “CAL”. When you are done calibrating, return the switch to “RUN” to protect against change. How to calibrate the scale The following details the calibration procedure for the crane scale.
CS750, Users Rev R, May 2009 Start up 1. Move the calibration blocking switch to the “CAL” position if you intend to calibrate. 2. Turn scale power ON and wait for scale to warm up (3 minutes from power on). 3. Press ZERO and hidden keys together and release to enter the calibration mode. First ten parameters 4. The scale shows “EE-EE EE-EE”. EE-10” 1”. EE-EE Press the zero key. To skip to “EE-10 EE-10 enter a “1 To skip to “LL-00 LL-00” 2”. No skips will occur with an entry of “0 0”. LL-00 enter “2 5.
CS750, Users Rev R, May 2009 9. The scale shows “EE-04 EE-04”. EE-04 Press the zero key. Enter the auto off time in minutes (0 to 255). The auto off time is how long the scale will remain ON without any activity (a key being pressed or a change in weight). An entry of 0 turns the auto off feature OFF. 10. The scale shows “EE-05 EE-05”. EE-05 Press the zero key. Enter what unit of measure the scale should turn ON in; pounds or kilograms (0 to 1).
CS750, Users Rev R, May 2009 Last five parameters. 15. The scale shows “EE-10 EE-10”. EE-10 Press the zero key. Enter the AZT size (0 to 3). The AZT size is the number of graduations the auto zero tracking can remove. Setting 0 1 2 3 AZT size Off 0.6 1.0 3.0 16. The scale shows “EE-11 EE-11”. EE-11 Press the zero key. Enter whether the zero range is on or off (0 to 1). If the zero range is ON the push-button zero and AZSM can only operate within +/- 5% of the original zero obtained at calibration.
CS750, Users Rev R, May 2009 18. The scale shows “EE-13 EE-13”. EE-13 Press the zero key. The scale shows the current initial zero range setting. Use the following table to select the “initial zero range” setting: Setting Initial zero range 0 Off 1 On A “0” setting implies: The initial zero setting mechanism (IZSM) will work over the entire range of the scale capacity and the over-capacity point is 103% above the zero obtained at calibration.
CS750, Users Rev R, May 2009 Save •At this point the scale saves any changes that have been made. This allows changes to be made to “EE-10 EE-10” EE-14” EE-10 through “EE-14 EE-14 without having to do a complete calibration. The scale can be turned off and any changes so far will be saved. Weight calibration 20. The scale shows “LL-00 LL-00”. LL-00 With no weight on hook press the zero key. This reads the pad zero. On the next screen, enter the scale's capacity. 21. The scale shows “LL-01 LL-01”.
CS750, Users Rev R, May 2009 Troubleshooting WARNING: Changing some parts on the circuit board may cause a large change in calibration while others may or may not change the calibration, depending on the nature of the problem. The reference designators for the IC chips are on the “A/D 20-BIT” board unless indicated otherwise. Problem: no power, nothing on display Fix: If nothing can be seen on the display, there is probably no power reaching the scale circuitry.
CS750, Users Rev R, May 2009 Problem: rechargeable battery life has decreased Fix: The rechargeable batteries provided by Intercomp are high quality, high capacity Ni-Cad. However, all Ni-Cad batteries can exhibit some “memory” effects if they are repeatedly discharged to a certain point before recharging.
CS750, Users Rev R, May 2009 Error Messages [Minus signs cycle across the display]: The CS750 has entered sleep mode. Press any key or change the weight to return to normal weighing. NOTE: a pressed key here will perform its designated function as well as exit the scale from sleep mode. [Minus signs fill the display]: The CS750 is waiting for a stable reading to continue. LB OE DISE EEPE OL E-0 Low batteries. This message blinks, and if ignored too long the unit will shut itself off.
