ARI Armaturen Elektrischer Schubantrieb FR 1.2 DE - Handbuch (Seite 7)

P100001973 - 7 -
For controllers with a continuous (0...10 V and/or 4...20 mA) or switched output (2- or 3-point
control). The valve drive has a spring function with a defined end position in case of a voltage
failure or if a limiter responds. The choice of characteristic (linear / equal-percentage / square)
can be set on the positioner.
Housing made of self-extinguishing blue plastic. DC motor, control electronics, LED display,
maintenance-free gear made of sintering steel, spring assembly, mounting column made of
stainless steel and mounting bracket made of cast light alloy to build on the valve. Further
properties: electronic, load-dependent switch-off using limit stops in the device or on the
valve, automatic adjustment to the valve stroke, coding switch to select characteristic curve
and run time. Crank handle for manual adjustment on the outside of the housing (with motor
switch-off, and to trigger re-initialisation). Possibility of external changeover of mode of action
(voltage supply to connection 2a or 2b), electrical connections (max. 2,5 mm ) with screwed
terminals. Three breakthrough-type cable leadthroughs for M20x1,5 (2x) and M16x1,5.
Installed position: vertical/upright to horizontal.

Accessories
Plug-in module for 230V ± 15% voltage, 2-point, 3-point and continuous control, additional
consumption 2 VA.
Double auxiliary switch continuously adjustable, max. load 6(2) A and 12 ... 250 V~, minimum
load 100 mA and 12 V.
1) The return time corresponds to a stroke of 20 or 30 mm and does not depend on the set run time
2) Also for 2-point or 3-point depending on the connection for 2a / 2b
3) Design the transformers for this value, otherwise functional faults may occur.
