Diagnostic functions
To use the diagnostic functions, simply press the
combination of keys “A + TEST”. The display shows
the following information:
Enc
AB
CD
123456
043
10
10
111100
The number under the field “ENC” indicates the
frequency (in kHz) detected by the encoder; this value
is proportional to the speed of the linear or rotary
labeling machine; in standard encoder installation
conditions, each unit of the figure equates to about 0.5
m/min or slightly less.
The numbers (0 or 1) under the fields A, B, C and D
enable you to control the status of the inputs for the
Start photocell (A), Stop photocell (B), enabling signal
(C) and second auxiliary input (D), which is currently
not in use. Pay attention to the fact that the enabling
signal must be on 1 for the machine to be able to
function.
The numbers (0 or 1) under the fields 1, 2, 3, 4, 5 and
6 are for controlling the status of the inputs for the
alarm signals, i.e. the driver ready contact (1), roller
microswitch (2) and empty reel sensor (3). In some
special configurations, there are also alarms for torn
paper (4), a second empty reel sensor (5), and an
additional alarm (6).
Functions accessible only to qualified personnel
The functions that are illustrated below are only
accessible by means of a confidential access code
(password). This password must only be
communicated to expert technicians.
Additional configuration parameters:
You can access the following parameters by
simultaneously pressing A+P, then inputting the
confidential password.
C04 – Enable alarms
Using this parameter you can enable or disable the
alarm signals.
The parameter’s value is obtained by adding together
the values associated with the individual signals that
you want to enable, or zero if you want the signals to
be ignored. The values associated with each signal
are:
– Alarm 1 (driver)
1
– Alarm 2 (roller microswitch)
2
– Alarm 3 (reel empty)
4
– Alarm 4 (torn paper)
8
– Alarm 5 (reel 2 empty)
16
– Alarm 6
32
– Internal alarm 1 (step limit)
64
In the default configuration, the code is 71, which
coincides with enabling the first 3 external alarms plus
the step limit alarm.
C05 – Constant speed?
This parameter is used to choose whether the label
delivery speed is to be constant (corresponding to the
value specified in the parameter P00 – Speed) or
synchronized with an encoder.
Input YES to choose the constant speed mode or NO
to enable the synchronized mode with the encoder.
The mode you choose affects the meaning of the
parameters P00 (Speed) and P01 (Start delay).
In constant speed mode, any signal coming from the
encoder is ignored.
C06 –55 mm roller?
This parameter only takes effect if the constant speed
mode has been selected. You need to input YES if the
paper-driving roller is 55 mm in diameter (standard on
the 90 m/min machines); or you input NO if the paper-
driving roller is 40 mm in diameter (standard on the 60
m/min machines).
Additional size parameters:
P05 - Stop Dark-Light?
Input YES to stop the label on the dark-light transition,
or NO to stop on the opposite transition.
P06 – Speed compensation
The speed compensation takes effect by anticipating
the delivery of the label in proportion to the speed
measured by the encoder. A value of 16 in P06 (the
default value set at the factory) coincides with the
compensation of a total delay of 1 msec in the system;
in these conditions, P01 must be at least 256. If you
increase the value of P06 you need to increase P01
proportionally as well.
P07 – Ramp No.
On machines with two control cards (PL001-
PL002)
: you can set values from 0 to 7 (8 types of
ramp); ramp 0 is the slowest and ramp 7 is the fastest.
It is advisable to use ramp 3 on the faster machines.
On machines up to 40-60 m/min, you can use ramp n.
6. Ramp n. 7 is only used for narrow labels (less than
20 mm approx.).
