2 Safety The machine should be placed in an area where it can be ensured that unauthorized persons do not have access to it.

Carefully read this instruction manual before starting the machine and using it. Follow safety instructions.

ONLY SPECIALLY TRAINED PERSONNEL SHOULD USE THE MACHINE, AND THEY MUST HAVE ATTENDED A COURSE HELD BY VELFAG EHF. ON THE USE, MAINTENANCE AND SETTINGS FOR M700 MACHINES! It is forbidden to remove or change the manufacturer's safety equipment on the machine. Such actions will create hazards for the people working in and around the machine and invalidate the CE marking of the machine and its warranty conditions from the manufacturer.

Before using the machine, one must:

1. Close all machine guards and covers.

2. Test the safety equipment; Emergency stop buttons should stop the machine: a) Emergency stop buttons (2 & 3) are located on either side of the machine by the outfeed guards (16). b) Emergency stop bar (4) is located above the infeed area (10) c) Emergency stop sensors (5) are located on the infeed- (15) and outfeed guards (16) and stop the machine automatically if the guards are opened.

During an emergency stop, the power supply to the machine will shut off, the machine stops and the circuit breaker in the fuse box will disconnect.

3. Cancelling an emergency stop command and restarting the machine: a) If an emergency stop button on the machine (2, 3 or 4) has been used, it needs to be turned clockwise, so that it returns to its original position before the Reset button is pressed (8). b) Press the Reset button (8) on the control panel or press “Reset” in the HMI operating system. c) After the reset, you can restart the machine by pressing the “Start” button (6) on the control panel.

CAUTION! The motors of the machine can get very hot!

It is normal for them to operate at temperatures above 80°C. Such temperatures can cause burning if in direct contact with skin.

Always use safety gloves when working on the machine

10

2.1 Safety matters DANGER! It is forbidden to open the machines safety guards or work on the machine whilst the safety guards are open unless the machine has first been stopped using the emergency button/bar and all the machines power disconnected at the circuit breaker in the fuse box.

IMPORTANT INFORMATION FOR OPERATORS OF THE MACHINE: DANGER! ACCIDENT HAZARD DUE TO FAST ROTATING CUTTING KNIVES, CONVEYORS AND OTHER MOVING PARTS. USE EXTREME CAUTION WHEN OPERATING, ADJUSTING, MAINTAINING AND REPAIRING:

1. The machine should be located where it can be ensured that unauthorized persons do not have access to it.

Ensure that an employee who works on or by the machine can call for help if there is danger from its use or from working in proximity to it.

Employees or other people who work on or by the machine, heading, cleaning, doing repairs, adjustments or other work connected to the machine or in close proximity, should never work alone.

2. Never put your hands or other body parts into the infeed area (10), heading area (11), outfeed area (12) or any other part of the machine that has movable gears or processing equipment, when the machine is running or when the machine has not been disconnected using the emergency stop.

3. The machine operator must feed the machine by loading the fish onto the movable conveyor (13), which conveys the fish into the machine for heading. Extreme caution should be taken in this work so that hands do not get stuck in the conveyors. Remove hands from fish before it goes into the heading area (11).

4. NOTE! If you need to access the dangerous areas of the machine in order to unclog blockages / remove stuck items, adjust the machine or take care of other maintenance and repairs, then you must, without exception, begin by disconnecting the machine using the emergency stop button to turn off the power to the machine.

Personal protective equipment: When working on or using the machine, operators must use personal protective equipment that has been certified by the relevant regulatory agency. The personal protective equipment must protect the operator to the greatest extent possible from any anticipated and potential hazards relating to the use, adjustment, repair and maintenance of the machine, such as, but without being limited to: • Contact with sharp knives • Blows or crushing resulting from movable machine parts. Foreign bodies that may be ejected from the raw materials during processing • Cold • Water • Noise pollution • Slippery floor and other slippery surfaces by or on the machine Example: Waterproof clothing, safety gloves woven with steel fibers, hearing protectors, rubber gloves, rubber sleeves, safety goggles, safety boots.

ATTENTION! Do not wear rings, watches, scarfs or other items that increase the risk of getting entangled or stuck in the machine while it is in use. Do not use work clothing that presents a risk of flapping about and / or gets caught in the moving equipment of the machine.

DANGER! Never put your hands or other body parts into the dangerous areas of the machine to clear it, without stopping the machine first, using the emergency stop!

3 Instructions for use 3.1 Start-up and shutdown When turning on the machine via the main power switch it is normal to wait 1-2 minutes before the machine boots up and the “Login” screen appears.

1.

All guards on the machine must be closed and covered. Make sure that starting the machine will not pose any danger.

2. Testing of safety equipment: See section on safety matters.

The emergency button/bar should normally only be used to stop the machine in an emergency, as stopping the machine in this way causes unnecessary stress on the machine’s electronics.

3. The machine must have a steady flow of water before it is started.

Start the machine by pushing the “Start/Stop” button on the control panel and stop it by pushing the “Start/Stop” button.

Pressing the “Start” button will activate all functions that are checked-in in the “settings” menu in the HMI (9)

Figure 3.3

4. If you need to adjust the position of the fish on infeed guides or if the fish is placed incorrectly in the machine, causing sufficient resistance to cause the conveyor drive to stop, the fish may be reversed out of the infeed area by stopping the machine, pressing, and holding the “BACK” button on the control panel (7).

Reposition the fish and/or remove whatever has caused the misalignment. Press the “START” button on the control panel and continue with normal operation.

12

3.2 Login and language Users login to the machine using an RF-ID token (A) or entering username and password provided by Vélfag:

3.3 Operating method 1.

Remove a fish, that has been gutted or headed and gutted from the supply belt. Fish must still have the collarbone on both sides.

2. Place the pectoral fins of the fish and subsequently the collarbones on the infeed guides, with the belly of the fish pointing into the machine. See figure 3.7 3. The operator must let go of the fish before it enters the cutting knives!

4. The infeed belts then drive the fish towards the heading knives and release the fish onto the outfeed conveyor once the heading/collarbone cutting has completed.

5. The heads/collarbones go down a slide on either side of the machine after being removed from the body.

Figure 3.7

The fish must be placed perpendicular onto the infeed guides to get an even cut on both sides. Wrong infeed will result in heading flaws and loss of yield.

14

When placing fish with head on the infeed guides, make sure to have the pectoral fin and the collarbone riding on top of the guides or else the collarbone will still be attached to the body after beheading.

15

3.4 Drive and manual control The runtime menu in the HMI touch screen has buttons to start, stop and reset the machine

Figure 3.9

The ‘Manual’ menu enables the user to control most of the operations and every motor of the machine, one at a time.

Figure 3.10

Note that on machines that are combined with a M705 filleting machine in a line, the HMI is placed on the filleting machine and the M521 heading machine controlled from there.

7 HMI settings Note that on machines that are combined with a M705 filleting machine in a line, the HMI is placed on the filleting machine and the M521 heading machine controlled from there.

7.1 General settings and motor settings In order to manage the numerous elements of the M521 (motors, electric components and water), the user can enter the “Settings” menu and “check in” or “check out” (figure 7.1) each of the motors and run them individually or together. This makes it easier for the user to troubleshoot and better understand the machine.

Only “checked in” motors will run when machine is started.
