Operating and installation instructions
Thrust actuator ARI-PREMIO
5.5.14 Electronic position indicator RI32
The RI32 electronic indicator transforms a resistance change into a 4...20mA or 2...10V
standardised control signal.
The RI32 position indicator can be operated by 24V DC voltage or 24V AC voltage.
It is possible to link into a current loop without an additional power supply.
5.5.14.1 Useful range of the linear motion
potentiometer
Linear motion potentiometers R1 or R2 are
connected in a three-conductor connection.
Here the RI32 position indicator is also suitable
for conductive plastic potentiometers.
The diagram on the right will help when
adjusting the RI32 position indicator to the
stroke distance of the linear motion
potentiometer.
It is important that the mechanical stroke
distance of the control actuator is smaller than
the stroke distance of the linear motion
potentiometer.

5.5.14.2 Installing the RI32 electronic position indicator in the PREMIO
- The RI32 position indicator is fitted to the ARI-PREMIO as illustrated.
- Screw fixing bracket (pos. 50.98) to gearbox cover plate with head cap screw (pos. 50.81).
- Then fit position indicator (pos. 50.121) to fixing bracket (pos. 50.98) with the head cap
screws (pos. 50.59) and washers (pos. 50.122).
