Make the function check for mounted auxiliary switches according to the following
table – example switching point at 25% position:
Connection terminals
Stroke
actuator
Rotary actuator
Terminal
S1 – S3
Terminal
S1 – S2
Voltage at Y2
Y = 0 V
Actuator’s stem
retracts (until
end position is
reached)
Actuator’s spindle
turns in counter-
clockwise direction
(until end position is
reached)
- -
No voltage at Y1
und Y2
Y = 0 V
Actuator’s stem
maintains the
position
Actuator’s spindle
maintains the
position
Voltage at Y1 for
desired valve
position % + 2% x
positioning time
Example:
SAX31.00 = 27% x
120 sec = 32.5 sec
Valve
position %
+ 2%
Y = 2.7 V
Actuator’s stem
extends to
desired position
(27%)
Actuator’s spindle
turns in clockwise
direction to desired
position (27%)
Check switching point with
voltmeter
Actuator’s stem
maintains the
position
Actuator’s spindle
maintains the
position

Make the function check for mounted potentiometer according to the following table
(Example values for ASZ7.5):
Connection terminals
Stroke
actuator
Rotary actuator
Terminal
P1 – P2
Terminal
P2 – P3
Voltage at Y2
Actuator’s stem
retracts (until
end position is
reached)
Actuator’s spindle
turns in counter-
clockwise direction
(until end position is
reached)
- -
No voltage at Y1 und Y2
Actuator’s stem
maintains the
position
Actuator’s spindle
maintains the
position
< 1 Ω > 996 Ω
Voltage at Y1 for desired valve
position % positioning time
Example:
SAX31.00 = 75% x 120 sec = 90
sec
Actuator’s stem
extends to
desired position
(75%)
Actuator’s spindle
turns in clockwise
direction to desired
position (75%)
- -
Check position value with
ohmmeter
Actuator’s stem
maintains the
position
Actuator’s spindle
maintains the
position
~ 560 Ω ~ 436 Ω
Voltage at Y2 for desired change
of valve position % x positioning
time
Example:
SAX31.00 = 10% x 120 sec = 12
sec
Actuator’s stem
retracts to
desired position
(65%)
Actuator’s spindle
turns in counter-
clockwise to desired
position (65%)
- -
Check position value with
ohmmeter
Actuator’s stem
maintains the
position
Actuator’s spindle
maintains the
position
~ 485 Ω ~ 511 Ω
