6.2 Menu functions
The menu functions are explained in detail here.
Permanent test___________________________________________________DTST
The permanent test makes a test run without using labels. In the display the numbers of
dispense cycles is shown (see description LABC). Immediately after starting the function, the
machine runs in a self-test. The test run works with all adjusted parameters. The test can be
stopped by pressing the key ENTER.
Polarity of the product sensor ______________________________________ P_S_
The machine requires a start signal for each product to be labelled. After the start delay (STAD)
the labelling starts. The signal is usually created by a light sensor at the conveyor. A PLC can
also supply this signal. The light sensor supplies a signal when the light beam is interrupted by
the product. By means of the function P_S_ it will be selected whether the leading edge or the
trailing edge of the product should trigger the signal.
Usually the trailing edge of a product is used. Reasons for detecting the leading edge can be:
- shape of product (your should avoid detecting a radius or a declined edge)
In case of using other than the standard product sensor’s, the meaning of the display can be
reversed. The adjustment you need you may change with the keys NEXT or PRIOR.
Factory adjustment: LEDG
Machine type ___________________________________________________ MACH
The software is identical for several different machines. Choice the correct type.
Dispensing direction ______________________________________________ MDIR
The machine is available in a right and left-hand version. In the right hand version the product
transport is from left to right when you look to the front of the machine. The adjustment is done
in the factory and should not be changed.
