the timer, alter manual greasing. If we don’t want to see the notification to grease the
machine we can set the timer value at 0.
Cycles to grease chain. This is the number of chain greases made if the machine has
automatic chain greasing.
Check pump oil and filter. The set point value is used to choose the time we want the
machine to notify the advance time. We can use the present value to display the
time that has passed since the last reset
1.10.5 PRINTED FILM PHOTOCELL
The next parameters only will be configured if the machine has upper film
centering system.
Photocell errors cycles. It is the number of cycles that the spot isn’t detected inside
the established limits, to stop the machine with an error. This applies both, to count
the upper and lower photocell.
Spot window. This parameter is that we use to generate the window to read spot. It is
the distance before and after the value of spot setpoint position, in which we will
look the spot, to calculate the position of braking. To take the error the spot must be
outside that window.
Brake enhance. With this parameter controls the magnitude of the braking. You can
center the film making several soft stops, stretching little by little, or rather, make a
hard braking and centering the film in very few cycles. The default is 35%.
Min brake distance. It is the minimum distance from braking that is done to the
machine, although the picture does not go backward and we need to brake. This
parameter is often used to always have a minimum stretch of film, especially in
cases where the product out of the pack. The default is 0mm.
Max brake distance. This is the limit we use braking. We believe that a greater
braking it might cause a rupture of film or problems centring due to excessive
stretching. That is, if the result of the mathematical operation that we carried out in
section 7, gives us a value exceeding the maximum braking distance, we value the
latter case. The default is 35 mm.
