DUAL APPLY MODES
Only displayed if the system Apply Mode (
page 35
) is set to 2 Tamps, 2
Tamp/Blows, or 2 Blows. Calculated the same as above, but with extra
time to allow the second label to feed and be ready for the second
application. If the second label is not ready in time, a Timing
Violation warning will be given.
ONLY TAMP MODES
This setting controls the extension stroke time. If the auto-retract
sensor is not used, this is the only setting that controls the retract of
the tamp cylinder. If the Apply Mode (
page 35
) is set for Blow, this will
be the duration of the blow cycle.
ONLY DUAL APPLY TAMP MODES
Only displayed if the system Apply Mode (
page 35
) is set to 2 Tamps, 2
Tamp/Blows, or 2 Blows. This controls the second application extension
time.
ONLY TAMP MODES
In this screen, a waiting period between the cylinder returning home
and the next label fed can be adjusted. This delay can be useful for
allowing the tamp pad to settle, before a label is advanced from the
drive module.
ONLY TAMP MODES WITH AUTO-RETRACT SENSOR
If the optional auto-retract sensor is installed (OTS screens,
page 33
),
this screen will be visible for adjustments. The auto-retract sensor will
detect the product surface before contact. This allows the lightest
touch of the label to the product, which can accomplish nearly the
same effect as a tamp/blow on many products and have the benefit of
positive contact to ensure label transfer onto the product surface. Since
the speed of the cylinder can vary, based on the pressure and flow
control settings, the auto-retract employs an adjustable delay. This
delay is started when the sensor first “sees” the product, and allows
additional time to contact the product. If the delay is set too short, the
tamp pad may never hit the product. If set too long, it will hit the
product too hard. If it is set to zero, the auto-retract will be disabled,
and the system will solely use the tamp duration timer to cause retract.
ONLY TAMP MODES WITH LABEL PRESENT SENSOR
If the optional Label Present sensor is installed (OTS screens,
page 33
), this screen will be visible. The Repeat screen allows a safe
guard to be set to prevent multiple labels to be fed for a single tamp,
and/or prevent multiple application attempts of the same label. The
repeat feed function can set a limit to the number of labels fed to the
tamp pad for a single application cycle. Likewise, the repeat tamp
function can prevent applying the wrong label to the next product. In
applications where each label contains unique information for the
product this setting can stop the system from continuing if the label
returns with the tamp pad after an application cycle.
