ARI-PREMIO®-Plus 2G

Thrust actuator

Description

Field of application
ARI-PREMIO®-Plus 2G linear thrust actuators are employed to actuate control or shut-off valves requiring a nominal linear stroke distance.
The intelligent ARI-PREMIO®-Plus 2G thrust actuator is used whenever the actuator is controlled with an analogue signal (0 to 10 V/4 to 20 mA) or a 3-point signal and feedback information about positions, operating states, faults, etc. has to be output.

Method of functioning
The actuator has eight parameter switches for programming the most important actuator settings without a PC.
The valve final positions and the type of control are automatically determined by the electronics in an initialization run.
The desired position can be specified by means of the analogue control input.
The input is protected against polarity reversal. It can be configured as a current (4 to 20 mA) or voltage (0 to 10 V) input using a switch.
Alternatively, or additionally, the actuator can be controlled by means of a 3-point signal.
The electronics have two binary wide voltage inputs for this purpose (L↑, L↓) for all voltages from 12 V AC/DC to 250 V AC/DC.
The 3-point control signal takes priority over the analogue input signal, e.g. for fail-safe or anti-freeze protection. If a signal is present at both inputs (double control), the control mode is interrupted.
The spindle position is determined by means of non-contacting and non-wearing reflex sensors.
The electronics compare the setpoint with the actual value and correct the plug position accordingly.
The speed and positioning time can be varied with a 4-step slide switch.
The electronic detects a wire break in the 4 – 20 mA control signal.
The fail-safe behaviour in case of a control signal failure can be set with a 3-step slide switch.
The actual position (position feedback) can be output via the optional analogue output.
The output signal is configured as a current or voltage output using the same switch as for the analogue input signal.
The output is electrically isolated.
The optional relay card provides four unassigned relay outputs for alarm signals. The contacts are gold-plated.
