ETTING WORKING RANGE
One of the features of actuators series AR2...-SE, is the possibility to reduce the
working range of the actuator, i.e. contract the working range from 90° to 45° by
utilizing the whole input signal 4-20 mA or 0-10 V.
In order to limit the working range follow these steps:
1.
Turn the trimmer screw (shown in the picture) counter-clockwise for about 20
turns, the screw in endless.
2.
Supply power and set the input signal to the maximum value (i.e. 20 mA or
10V) and the actuator will turn :
♦
with rotation clockwise (dip-switch no. 1 on the right handside) up to
45°. Then the actuator will rotate by 45° between 45° and 0° with the
entire signal 4-20 mA or 0-10V.
♦
with rotation counter-clockwise (dip-switch no. 1 on the left handside)
up to 90°. Then the actuator will rotate by 45° between 90° up to 45°
with the entire signal 4-20 mA or 0-10V.
3.
In order to widen the working range it is possible to set any degree of angle
between 45° and 90° with a fine regulation.
Supply power and set the input signal to the maximum value (i.e. 20 mA or
10V) and turn the trimmer screw (as shown in the picture) clockwise, the
actuator will extend his working range by approx one degree for each turn of
the screw. Once you set the desired working range, the actuator will rotate
within this angle (i.e. 60°) with the entire input signal 4-20 mA or 0-10V.
