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.

2.2 – Sicurezze del dispositivo ed etichette di avvertenza The THS/21 Metal Detector is fitted with a list of safety features described below, in order to warrant the proper protection level, during the correct use. IP Protection degree All the system containers (probe and supply box) have a degree of protection (see the technical specifications) which ensure water tightness during operations and cleaning. All additional conveyor components have a protection degree of at least IP65. This also means that they are watertight. Cable glands The cable glands installed on the system are IP68 and they are dimensioned for M16, M20 and M25 cables. In order to maintain the protection degree, you must use cables with characteristics and diameter compliant with the device glands and following the guidelines specified in this manual. Insert only one cable for each gland and take care that all of them are mounted and tightened in the correct way. Do not remove the caps from unused glands. Self-diagnosis system An internal self-diagnosis system continuously monitors Metal Detector functional efficiency. In the event of a fault, a message is shown on the control display and all alarm indicators are activated together with corresponding relays. The access to Metal Detector parameters is protected by a six level system.

3.5.3 – Sensitivity check with reference sample It is important to check at regular intervals that the Metal Detector is operating efficiently. This is done running a detection and ejection test using test reference samples. -- Depending on product characteristics and/or internal quality procedures, the customers can use samples they have defined themselves or request specific samples from CEIA. -- The tests can be carried out at any time deemed necessary (e.g. at the shift changeover) and/or pre-programmed. In the latter case, the Metal Detector will automatically request the test. It is possible to test the detection capability of the Metal Detector by selecting the DEFAULT product mode and using one or more of the reference samples indicated in the Factory Acceptance test (FAT).

3.5.4 - Performing periodic tests ** TEST ** At the end of the Test period, a message requesting a test is displayed. At the same time the external blue lamp is activated (BLUE LAMP output) together with the Test relay Product:PROD01 (depending on the settings of TRM parameter). The test can be started by the quality control operator or the quality control supervisor (depending on the access level).
