Screen Function
Definition
Tension units
Toggle preferred tension measurement units. This will
be applied to any displays related to tension
measurements
Threshold ___%
Enter a value for the acceleration threshold. This
parameter determines a minimum amount of change in
web velocity before the ACCELeration COMPensation
feature activates. A lower value here will make the
feature more sensitive to changes in speed.
Tuned at core
Select STORE VALUES to save current tuning
parameters as the core tuning parameters; select
RECOVER VALUES to return to these same stored
settings at any time if they have been changed. See also
USE GAIN SCHEDULING.
Tuned at full roll
Select STORE VALUES to save current tuning
parameters as the full roll tuning parameters; select
RECOVER VALUES to return to these same stored
settings at any time if they have been changed. See also
USE GAIN SCHEDULING
Units & Language
Select to view options for the units of measure and
language to be applied to all CYGNUS screens
Unsecured
Select to enter security screen. A four digit code may be
entered to lock all calibration and parameter settings
and prevent manipulation by unauthorized users. The
same four digit code must be entered to unlock and
grant access to these settings. When UNSECURED is
displayed, any four digit code may be used regardless of
the last code used; see also SECURED
Unwind
Toggle this selection for applications where CYGNUS is
controlling a device that sets the tension in an unwind
zone. See also Figure 3
Use gain scheduling
Toggle to activate the gain scheduling feature that will
utilize different tuning parameters from full roll to core.
This feature requires a diameter sensor to function and
will compensate for changing tuning requirements
throughout the unwind or rewind process by using the
settings you provide at full roll and core and interpolating
the values for every diameter point in between.
Velocity sensor type
Toggle to activate an external velocity sensor. Check the
specifications for the sensor to determine if its output is
"pulse" or "voltage" type
Velocity___
Enter a value for the steady state line speed of your
machine
Voltage between TB6-1 & 2
Display of the voltage present corresponding to the load
cell signal input. This is useful for evaluating the
performance of load cells by comparing actual vs.
expected return signal for a given applied force.
Voltage on TB6-1
Display of the voltage present corresponding to the load
cell signal input. This is useful for evaluating the
performance of load cells by comparing actual vs.
expected return signal for a given applied force.
