Information
SAREx 16.2
Operate valve in desired end position (OPEN/CLOSED).
Reduce current value: Press push button [S1]
(the current is reduced by 0.02 mA every time the push button is
pressed)
Increase current value: Press push button [S2]
(the current is increased by 0.02 mA every time the push button is
pressed)
The LED behaviour for end position reached can be set as follows: blinking/continuous
illumination or no illumination. During setting mode, end positions signalling is
switched on.
1. Operate valve in one of the end positions (OPEN/CLOSED).
2. Hold down push buttons [S1] or [S2] for approx. 3 seconds.
End position signalling is switched on or off.

The potentiometer is used as travel sensor and records the valve position.
The potentiometer is housed in the actuator switch compartment. The switch
compartment must be opened to perform any settings. ➔ Refer to <Switch
compartment: open>.
Setting is made via potentiometer [1].

Due to the ratio of the reduction gearing, the complete resistance range/stroke is not
always covered. Therefore, external adjustment (setting potentiometer) must be
provided.
1. Move valve to end position CLOSED.
