6.1.2 Measurement menue selection
All 255 measuring programs can be selected via the PLC inputs.
For this the inputs IN0 to IN8 are used.
Attention: The inputs IN1-3 and IN5 are used also for functions other then the
selection of the measuring programs. This means that the sequence in the timing
diagram has to be followed exactly.

OUT 1,2,3
Check whether the output OUT0 „Enable" has switched to HIGH (ready for operation),
1
otherwise there is a fault condition.
Before selecting a measurement program, all inputs must be LOW for 30 milliseconds.
2
Switch the input IN0 „Menu selection" to HIGH.
3
Simultaneously with 3 (or delayed) switch the binary values to IN1-8.
4
Within 60 milliseconds after switching IN0 "Menu selection", the outputs OUT1-3 have switched to LOW.
5
After the binary value has been present for a minimum of 60 milliseconds, switch the input
6
IN0 „Menu selection" to LOW.
Simultaneously with 6 (or delayed) switch back the binary value at IN1-8 (switch IN1-8 to LOW).
7
After a maximum time of 180 / 480 / 240 milliseconds (depending on the material measured last and
8
the new type of material to be measured) all outputs OUT1-3 have switched to HIGH. If the configuration
„Demo mode" was selected, measurement will start automatically again (provided a valid program has
been selected). If the configuration „Measurement external" was selected, the operation of the unit it is
performed via the PLC.
