Fig. 32: Frequency-current diagram for a) Lower side band, b) Upper side band
‘Upper side band’
Using this processing type, you can control a metering pump using the
current signal as shown in the diagram above.
Everything functions according to the type of the processing ‘Lower side
band’ .
11.2.2
‘Automatic’
‘Menu / Information è Settings è Automatic è ...’
In the ‘Automatic’ menu, you can set whether the unit is to meter automat‐
ically or conventionally.
With ‘Automatic’ - ‘on’ you set direct values, such as capacity, metering
volume or dosing time instead of stroke length and stroke rate. The other
selection points will also appear in the operating menu - refer to the
chapter "Operating Menu for gamma/ X, complete" (in the appendix) for
the selection points highlighted with a "*1".
In
‘Automatic’ - ‘on’ metering mode, the gamma/ X specifies the stroke
length and the stroke rate according to the conditions determined in order
to meter the set capacity.
‘Automatic’ - ‘on’ and ‘Automatic’ - ‘off’ metering modes
are completely independent of each other. That is the say
that the ‘Automatic’ - ‘off’ does not carry over settings from
‘Automatic’ - ‘on’ .
11.2.3 ‘Stroke Length’
‘Menu / Information è Settings è Stroke length è ...’
The menu does not appear with ‘Automatic’ ‘on’ !
In the ‘Stroke length’ menu, you can enter the stroke length manually.
