Modes of operation - operation
Activating the sensor
Depending to the used label size (special the label length is important) the power stacker is
working in two different modes !
To understand that you should understand the principal – how the power stacker is working.
The unit is using reflex infra red sensor to check the height of the label stack – or if there is a
label !
Switching on the power stacker (via the TDI) with an empty platform and the platform is
down, the power stacker is moving up the platform until the first sensor is covered by the
platform -–the power stacker is ready for work. If now the second sensor is covered by
printed labels -the platform is moving down automatically.... the sensor is becoming free
again ... the next label is covering it ... and so on.
Depending to the label length a different stack mode is necessary. Short label need less
height to fall down properly then longer label. To compensate this different mode a second
pair of sensor is attached to the unit. The sensor pair can be selected with the attached
switch.
As a rule – label with less then 100 mm should use the upper sensor pair – longer label
should use the lower pair.
Attention: Switch in upper position means pair 1 – lower position pair 2 !
