THEORY OF OPERATION
TAMP CYLINDER RETURN OPTIONS
Dwell Timer (Standard on all L60 Tamp Applicators)
“Dwell Time” is the time duration of the signal that opens the valve, which activates
the air cylinder. This time duration can be adjusted with the three- turn dial located
on the front panel of the machine. Turn the dial clockwise and the duration to
increase the dwell time signal. After the label apply signal is given, the air cylinder
extends and the time duration terminates, the air cylinder then retracts and returns
the vacuum head to the home position.
Setting the Dwell time:
1. Turn the dial counter-clockwise to “0”.
2. Activate foot switch or product sensor. You will notice that the air cylinder will not
extend.
3. Turn the dial to “10”. The air cylinder should extend a short distance and return.
4. Turn the dial until the vacuum head touches the product. The dwell time is now
set. The distance of the machine from the product and air pressure will affect
this setting.
