5.2.2 Setting operating parameters
FOREWORD
The Hoyer Comet N machine is comprised of
working stations. Station settings are performed
during machine testing.
The machine is equipped with a jog devicewhich
mechanically transforms the continuous motion
of the belt drive motor into a jogging motion, this
allowing a jogging motion of the lamellas. The
movement of the belt is therefore made up of a
sequence of starts and stops. A special encoder
detects the position of the lamellas after each
step, and makes a full ratation (360°) at each step
forward of the belt. The angular position of the
lamella can therefore be identified and displayed,
so all the commands to the stations may be
performed. The commands, which raise and lower
Instructions on the OPERATOR panel to edit and enter data
mechanical and pneumatic organs and open and
close dosing valves, refer to encoder position.
The encoder must be reset at each revolution in
order to count positions at each step of the
machine.
Encoder resetting (performed through the PLC
and special sensor) is carried out when the lamel-
la belt starts to stop by effect of the jogging
device, therefore when the jogging device brings
the belt to a stop.
In this manner the mechanical part of the machine
and the electronic part, which carries out control
and adjustment functions, are timed together (in
phase). This timing is always carried out when
the machine is assembled and must be repeated
ONLY if the jogging device or the lamella belt is
replaced/overhauled.
To edit or enter data in any page of the operator
panel, select the page which includes the data to
be edited and press . A black cursor will flash
over the first datum which can be edited in the
page.
If you wish to edit this figure, enter the required
value with the numerical keypad. If the value to
enter includes more than one digit, as soon as the
first digit is entered the cursor will move on to the
second and so on until the last digit.
To shift among the digits in a value, use the
arrows ( ).
To move on to the following value, press
pdown
.
Once you have entered all the values in the page,
press
Enter
.
Then move on to the next page.
If the values entered and/or edited refer to a
format, save the values in the operator panel by
pressing
F7
and confirm by pressing
Enter
. Then
transfer the format to the PLC of the machine by
pressing
F8
.
