5.4.2 Setting the Tamp Dwell with the Hand-Held Terminal
The Tamp Dwell Menu Select Item on the Hand-Held Terminal adjusts the
amount of time that the cylinder waits before returning to its home position.
A lower Tamp Dwell value setting will reduce the time that the cylinder
waits and because the cylinder extension time is shorter, the cylinder's
stroke may be shorter.
To set the Tamp Dwell value:
1. Turn on the air by sliding the OSHA shut-off valve to the ON position.
2. Using the Hand-Held terminal, turn off the auto-retract.
3. On the Hand-Held Terminal press the MENU/SELECT key.
4. From the Menu screen, press the down arrow key twice until the
display shows the Tamp Dwell screen.
5. Observe the current Tamp Dwell value by pressing the
MENU/SELECT key to enter the Edit mode (the value will flash). To
begin with, set the Tamp Dwell value to 30. Note: A six inch
cylinder with a three inch tamp distance at 40 PSI completes its cycle
in about 0.235 seconds. Tamp cycle times are dependant on air flow
control, tamp air pressure psi and photosensor distance. Note the air
flow control instructions in Section 5.4.1. Tamp Dwell settings and
cycle time times for the PA/4000 are in the following chart:
Tamp
Dwell
Setting Complete
Cycle
Time in
Seconds
10 0.13
20 0.26
30 0.39
40 0.52
50 0.65
60 0.78
70 0.91
80 1.04
90 1.17
100 1.30
NOTE: Do not set the Tamp Dwell value any longer than the time
required for full tamp cylinder extension.
6. Press the MENU/SELECT key to save
the new value. The value you enter will
not be used until the MENU/SELECT
key is pressed and the display is no
longer flashing. Hold the 2nd key and
press the MENU/SELECT key while the
display is still flashing to CANCEL.
7. Observe how far the cylinder extends
before it retracts. Use the arrow keys to
increase the DWELL value so that the
cylinder extends but does not reach the
product. Turn on the conveyor. Adjust
the Tamp Dwell setting until labels are
reliably applied to every product.
Record the final dwell value on the
PA/4000 Configuration Sheet. See
Section 6.
