Design and Function
2.4 Control types
Version “Internal stroke rate setting” (identity code characteristic “Control type”: 0):
The controlling pulse is internally generated, stroke length and stroke rate can be manually
adjusted using the control buttons on the operating panel.
Versions “External contact control” (identity code characteristic “Control type”: 1, 4):
The controlling pulse is externally generated, from potential-free or semiconductor contacts and
fed to the drive unit via the “external control” jack; examples are contact water meter or
DULCOMETER® controls.
Versions “Analog control x - 20 mA”
(Identity code characteristic “Control type”: 2, 3, 5, 6):
An external, analogue signal is fed to the drive unit via the “External control” jack;
the stroke rate changes proportionally according to the 0 .. 20 mA or 4 .. 20 mA signal.
Versions “Internal stroke rate setting with pause function”
(Identity code characteristic “Control type”: 7, 8):
As for version “Internal stroke rate setting”, however there is also the possibility of switching the
metering on and off via an external semiconductor contact or potential-free contact.
NOTE
All control types, that can be controlled via an input, can be supplied with an “External
control” input of “non-intrinsically safe” or “intrinsically safe” type [i, a].
