AUMA SAEx 10.2 User Manual

5. Perform setting in the second end position following the same steps.
6. Approach both end positions again to check the setting.
→
If the measuring range cannot be set:
Refer to <Faults during commissioning>.
→
If the current values (0/4/20 mA) are incorrect:
Refer to <Current values: adjust>.
→
If the current value fluctuates (e.g. Between 4.0 – 4.2 mA):
Switch off LED end position signalling.
Refer to <LED end position signalling: switch on/off>.
11.1.2. Current values : adjust
The current values (0/4/20 mA) set in end positions can be adjusted at any time.
Common values are e.g. 0.1 mA (instead of 0 mA) or 4.1 mA (instead 4 mA).
Information If the current value fluctuates (e.g. between 4.0 – 4.2mA), the <LED end position
signalling> must be switched off for current adjustment.
→
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)
11.1.3. LED end position signalling: switch on/off
The LED behaviour for end position reached can be set as follows: blinking/continuous
illumination or no illumination. During setting mode, end position signalling is switched
on.
Switching on and off
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.

11.2. Potentiometer
The potentiometer is used as travel sensor and records the valve position.
Setting elements
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].
