Descriptive Annex

1 INTRODUCTION This pattern of an automatic catchweighing instrument, designated the CW3, operates as an automatic checkweigher (Category X). The instrument comprises a cabinet with user interface, weighing device, mechanical handling facilities and reject device. The instrument is designed to weigh packs dynamically. 2 DESCRIPTION

2.1 Mechanical 2.1.1 The instrument (Figure 1) is constructed in stainless steel. The framework is a fabricated floor standing stainless steel frame on adjustable feet. On the frame are mounted the modular conveyor sections (in-feed, weigh platform, and out-feed) and the main cabinet with console. The out-feed conveyor can be equipped with one of a number of reject devices, including a flipper, drop flap, ram or air blast. The instrument is designed to be permanently installed. 2.1.2 The control cabinet, situated at the front of the instrument, houses the electrical hardware. A console, mounted above the control cabinet contains the keyboard and display in the form of a touch screen. Photocells mounted at either end and either side of the conveyor are used for pack detection. The photocells may also be over head photocells type PEC. 2.1.3 Packs are weighed as they pass over the weigh head conveyor which runs continuously at the speed of the in-feed and out-feed conveyors. The weighing system is constructed around a Vishay Tedea Huntleigh 240 C3 load cell, capacity 10 or 20 kg (see 2.4.1), located under the weigh platform. The load cell is thermostatically controlled and is housed in an oil filled box. 2.2 Electrical 2.2.1 The control cabinet is accessed from a door at the front. Inside are the PC console, load cell module, filters, circuit breakers, power supplies, motor drive cards and appropriate input/output modules type X20 for external electrical interfaces such as the out-feed mechanisms and external peripherals. 2.2.2 The load cell module type X20AI1744-3 is directly connected to the load cell with a 6-wire cable and reads and digitises the analogue load cell signal with a 24bit ADC type B&R. The CPU type Intel Geode reads this digital value and performs digital filtering and processing of the signal to produce the individual pack weight. 2.2.3 Mounted towards the top of the control cabinet is an aluminium-enclosed PC console manufactured by B&R and designated the PP420. It houses a 10.4-inch colour touch screen (Figure 2), interface ports, processor type Geode LX800 500MHz, 64Mb SDRAM, Compact Flash card, power buttons and status LED’s. It communicates with the load cell and I/O modules via X20 Link. 2.2.4 The Compact Flash card, type I, capacity up to 2 GB, is inserted in a slot located on the side of the console and can be secured using the rotating latch. The card contains all the firmware with programs and data.

3/19

2.3 Weigh platform unit 2.3.1 The load cell is a Vishay Tedea Huntleigh 240 C3, capacity 10 kg (Lightweight variant, maximum capacity 1500g) or 20 kg (Mid-Range variant, maximum capacity 6000g). The PC console provides the 5.5 VDC excitation voltage. Alternatively, any compatible load cell may be used providing the following conditions are met:

There is a respective OIML Certificate of Conformity (R60) or a parts/test certificate (EN45501) issued for the load cell by a Notified Body responsible for type examination under Directive 2014/31/EU.

The certificate contains the load cell types and the necessary load cell data required for the manufacturer’s declaration of compatibility of modules (WELMEC 2, 2015, No 10), and any particular installation requirements. A load cell marked NH is allowed only if humidity testing to EN45501 has been conducted on this load cell.

It is not a load cell with digital output

The characteristics of the replacement load cell such as nlc, Y, Z are the same or better than the load cell tested dynamically (Vishay Tedea Huntleigh 240 C3, Emax = 10 kg)

The design of the load cells and the material are the same

No oil damper is used

The sensitivity is greater than 0.67 µV/division 2.3.2 The system uses the in-feed and out-feed photocells to detect the arrival and passing of any packs. The “Auto Zero” mode is active when there are no packs on the platform. The weight signal is continually monitored to find the optimal point at which to take the final product weight. The analogue output is then sent to the load cell module to be digitised and processed before it is sent to the PC. 2.4 Devices

2.4.1 The instrument has the following devices:

Automatic zero setting device active during automatic operation (active if the time between two packs is more than 500 ms)

Pre-set tare device (subtractive) Static calibration not accessible to the user Dynamic calibration accessible to the user Belt speed setting accessible to the user Internal memory for storage of batch reports Device to determine the stability of equilibrium, active during dynamic

operation Device that acts upon significant faults Screen check at power-up
