1 Introduction IT CHECK E is a versatile checkweighing terminal for automatic control of piece goods. Due to its modular design and setup options, it can be easily adapted to a variety of weighing applications with belt and/or roller conveyors.

1.1 Safety Symbols Used In This Manual Safety relevant information is shown with corresponding symbols as follows:

W A R N I N G Failure to observe this precaution could result in serious injuries or fatal accidents. Please make absolutely sure that these precautions are observed in order to ensure safe operation of the equipment.

CAUTION Failure to observe this precaution could result in damage to or destruction of the equipment or bodily harm! Please make absolutely sure that these precautions are observed in order to ensure safe operation of the equipment.

This symbol indicates a step in the operating sequence.

Note: This indicates an advice for the designated use of the equipment and/or additional information to avoid inappropriate handling.

1.2 Safety Advice

W A R N I N G Disconnect all power to this instrument before opening the housing! Risk of electrical shock!

W A R N I N G Exercise utmost care when making checks, tests and adjustments that can actuate movable parts such as feeding devices, gates, flaps, conveyors, etc. Make absolutely sure that nobody is within reach of movable parts.

W A R N I N G This unit must not be operated in a potentially explosive atmosphere! It is the sole responsibility of the user to classify the area of installation and make sure that absolutely no potentially explosive atmosphere can be present at any time!

CAUTION Input voltage of the instrument must comply with local mains supply!

CAUTION If the line cord with connector is used as the means to separate the instrument from the mains, the wall outlet must be installed close to the instrument and must be easily accessible! If a permanently connected mains cable is used, an easily accessible separator must be included in the supply circuit!

CAUTION The power supply unit of the weighing terminal provides SELV voltages in accordance with EN 60950. Make sure that any peripheral device connected to the weighing terminal containing its own power supply also uses SELV voltages!


CAUTION This unit must be installed, serviced and operated in strict compliance with all locally applicable safety regulations and the rules for the prevention of accidents!

CAUTION When this unit is included as a component part of a system, the resulting system design must be reviewed by qualified personnel who are familiar with the construction and operation of all individual components in the system and the potential hazards involved.

CAUTION If this device is used in an automatic or manual filling cycle, all users must provide a hard wired emergency stop circuit outside the device circuitry.

CAUTION This module and its associated equipment must be installed, adjusted and maintained by qualified personnel only!

Note:

• The unit does not have a mains switch and is operational immediately after connection to the mains supply!

• Only permit qualified personnel to operate this instrument! Disconnect all power to this instrument before cleaning and servicing!

• All switch gear connected to the unit and/or installed close to it, such as relays and contactors, must be fitted with appropriate components (RC-modules, diodes) to suppress interference.

• In order to avoid static discharge, all metallic parts of a system must be thoroughly grounded. Movable parts, such as portable scales on plastic wheels, must be grounded with earth clamps or earth leads of appropriate diameter.

• Keep this manual for future reference!

6 Tolerance Zones The product-related nominal weights and thresholds for the classification in 3 or 5 zones are entered in the product file. Depending on the classification of each test object, the statistics file is updated and the output signals are set.

Example for the classification into the 5 zones ++, +, ok, –, and ––, with a nominal weight of 100kg and:

—— tolerance = 2kg — tolerance = 1kg + tolerance = 1kg ++ tolerance = 2kg

Zone Weights Control Parameters

++

102kg ++ Tolerance

+ 101kg + Tolerance

100kg

Target ok

99kg – Tolerance

- 98kg –– Tolerance

--

0 0kg

If an approved weight cannot be captured, all zone outputs are set and zone 'EE' is displayed. The test object must be removed and checked separately. Classification in 3 zones: If ++Tolerance and ——Tolerance are not specified, the checked weights are only classified in the three zones +, ok, and —.


7 Statistics Protocol If the nominal weight is ≤ 10 kg (or ≤ 10000g), a statistics protocol is printed for each finished batch. Rejected test objects are shown separately and are ignored for the calculation of the mean value. The limits for TU2, TU1, TO2 and TO1 are calculated automatically and do not necessarily comply with the thresholds set for the individual zones. Test objects under TU2 must be ejected. Example for printout:

8 Transport, Maintenance And Cleaning 8.1 Transport Notes:

• Transport and storage of electronic components such as boards, EPROMS, etc. must only be made in suitable anti-static ESD bags or cases.

• Storage temperature –25 to +70°C at 95% max. relative humidity without condensation.

8.2 Maintenance

CAUTION This unit and its associated equipment must be maintained by qualified personnel only, who are familiar with the construction and operation of all equipment in the system and the potential hazards involved. Failure to observe these precautions could result in bodily injury! Disconnect all power to this unit before servicing!

The ITX000E terminal is designed to require a minimum of maintenance and service, however, depending on the environmental conditions a visual inspection at regular intervals is recommended. The frequency at which normal maintenance (cleaning and inspection) should be performed, when installed in a clean office environment, should be twice a year. However, if the unit is subject to a dusty or dirty environment the frequency should be increased as required. At these inspections it should be made sure that all connected cables are undamaged and that all connectors are tightly fastened. Maintenance of scale platforms is required at regular intervals depending on use and environment. The accuracy of scales can be affected by dirt, foreign objects, etc. and appropriate maintenance is strongly recommended. Also recommended is the calibration with certified test weights at regular intervals.

8.3 Cleaning

CAUTION Disconnect all power to this unit before servicing!

Clean the keyboard and covers with a soft clean cloth that has been dampened with a mild window type cleaner. Do NOT use any type of industrial solvent or the finish of the unit may be damaged. Do not spray cleaner directly on the unit


9 Trouble Shooting

CAUTION This unit does not contain any customer serviceable parts! Only permit qualified personnel to service this equipment. Exercise care when making checks, tests, and adjustments!

If any problem arises that has not been explained above, please follow this check list:

• Power supply on and line cord undamaged (visual inspection)? • All cables connecting to scales and peripheral devices undamaged (visual inspection)? • Connectors fitted correctly and tightly secured at peripheral devices (visual inspection)?

If operational difficulties are encountered that cannot be rectified by means of this manual, obtain as much information as possible regarding the particular trouble, as this may eliminate a lengthy, detailed checkout procedure. If possible, try first to determine the conditions under which the problem occurs. Try to find out whether the appearance of the difficulties can be reproduced under the same conditions.

For the systematic analysis of an unknown problem the information as listed below is required:

• Serial-No. of the unit and its peripheral components • Program version as displayed on power up • Exact wording of any error message displayed • Type and model of peripheral devices related to the problem (e.g. scale, printer, etc.)

To obtain professional assistance contact your service station stating the information listed above.

CAUTION It is suggested that assistance from trained service personnel be requested in the event a problem should arise that is beyond the scope of this instruction manual.
