AVM 234S
Sauter Components
Operation
Depending on the type of connection (see the wiring diagram), the actuator may be used as a continuous
(0...10 V and/or 4...20 mA), 2-point (OPEN/CLOSED) or 3-point (OPEN/STOP/CLOSED) device with an
intermediate position.
The actuator's running time can be set according to the specific requirements, using switches S1 and S2.
Switches S3 and S4 are used to set the characteristic (equal percentage, linear or quadratic).
The external lever allows you to adjust the position manually. When the lever is folded out, the motor cuts
out. When the lever is folded back into place, the setpoint position is adopted again (without initialisation).
If the lever is folded out again, the actuator stays in this position.
Initialisation and feedback signal
When used as a continuous actuator, the device initialises itself automatically. As soon as power is ap-
plied to the actuator for the first time, it moves to the valve's lower limit, thus enabling automatic connec-
tion with the valve spindle. Then it moves to the upper limit and the value is recorded and saved by a
travel measurement system. The control signal and the feedback signal are adjusted to this actual stroke.
There is no re-initialisation in the event of a power failure. The values are saved.
To re-initialise, the actuator must be connected to the power supply and there must be a continuous input
signal at 3u or 3i. To trigger an initialisation, fold the lever out and back in again twice within 4 s. Both of
the LEDs will then flash red.
During initialisation, the feedback signal is inactive, or it corresponds to a value of 0. Initialisation uses the
shortest running time. The re-initialisation is not valid until the entire procedure has been completed.
Folding the lever out again will interrupt the procedure.
If the valve actuator detects a blockage, it will report this by setting the feedback signal to 0 V after ap-
prox. 90 s. However, the actuator will try to overcome the blockage during this time. If the blockage can
be rectified, the normal control function is activated again and the feedback signal is restored.
No initialisation is performed with 2-point or 3-point control. The feedback signal is inactive.
