10 FI002K0024v1000UK

1.2 – Permitted and improper uses

1.2.1 – Permitted uses

• The THS/21E and THS/21 electronic Metal Detectors are designed for the detection of magnetic and non-magnetic metal masses transiting inside the detection probe.

• Handle the device with care and without excessive force during installation, use and maintenance

• The final user is responsible for selecting the appropriate sensitivity for their application. After this selection has been made, and programming has been adjusted accordingly, it is also the final user's responsibility to check calibration using the test object(s) appropriate to the level of security selected. Calibration testing must also be performed at regular intervals to ensure the continued efficiency of the equipment.

1.2.2 – Improper uses

• The THS/21E and THS/21 Metal Detectors are not suitable for installation or use in explosive or potentially explosive atmospheres.

• Any maintenance or repair of the device while open and powered up should be avoided, and in any case should only be carried out by trained personnel who are fully aware of the risks which the operation entails.

• Electric arc welding must not be carried out on the detector probe, on the control power box or on any part of the attached structure.

• The device is fitted with mechanical and electronic protections, described in this manual. Removing or reducing these protections is forbidden.

• The machine is not designed for use in hazardous environments where there is a risk to the health and safety of the operator.

• We recommend that you do not use the equipment in very dry environments. Very dry environments can generate electrostatic charges.


11FI002K0024v1000UK

1.3 – Residual risks• Empty the reject material bin at regular intervals. Exercise caution when emptying the bin because it

could be heavy or contain very hot material. Define and implement a procedure for this operation. We decline all liability for injury to persons or damage to property caused by incorrect emptying of the reject material bin.

• Trapping and drawing in hazard. Body parts or loose dangling clothing can become trapped in the moving parts of the machine. Only authorised operators wearing suitably close-fitting overalls are permitted to work in this area.

• Tripping and slipping hazard. The absence of a reject material bin or a system for collecting ejected product can cause material to be deposited on the floor thereby creating a tripping and slipping hazard.

• Injury hazard to eyes, ears and sensitive body parts. When operating the machine do not approach the depressurising pipe of the blower ejector.

• Hard knocks to parts of the compressed air system can cause damage leading to leaks, bursting or the escape of compressed air.

• The machine is not fitted with a safety valve which depressurises the compressed air system in the event of a power failure which causes the lighting to fail. Automatic ejection systems (pusher cylinder or air jet types) will be powered down in the event of a power failure.

• The drive motor of the conveyor belt is covered by a metal guard except on the lower side and on the side facing the inside of the machine. Burns hazard: guard surfaces are very hot.

• Burns hazard. Caution hot surfaces. If the weight carried on the belt exceeds the limits specified in the technical data this will cause the motor to overheat. If dirt residues are not cleaned from the machine at regular intervals this also will cause the motor to overheat.

• Although the power of the laser beam used in barcode readers is very low, it can be dangerous to the human eye if stared into for long periods of time.

• Failure to follow the operating instructions in this manual may cause a loss of food characteristics. • On equipment where the material to be inspected is loaded and unloaded manually, it is the customer’s

responsibility to assess the risks to operator health and safety.• On integrated systems with the downstream conveyor connected up, the belt may start and stop

unexpectedly because it is controlled from this infeed line.
