Set the auto/manual switch in the manual position and apply power to the actuator. The
actuator can now be driven to the maximum position (switch cam I) or the full closed
"economy position" (switch cam II) by using the toggle switch located to the left of the
auto/manual switch.
See Figures 10 and 12.
Ensure that the OPE/MAX/MIN slide switch is set to operation (OPE). The blue MAX
trim potentiometer should be gently turned in the clockwise direction until the end stop
is reached. The blue MIN trim potentiometer should be gently turned in the
counterclockwise direction until the end stop is reached. Set the auto/manual switch in
the auto position. The actuator will now drive in response to the control input signal,
between the maximum position setting (switch cam I) and the minimum position setting
(switch cam III). If there is no control input signal, the actuator will drive to the minimum
position setting (switch cam III).
NOTE:
Switch Cam I must not be set higher than:
90° when using feedback potentiometers ASZxx..803,
135° when using feedback potentiometers ASZxx.833, or
160° when using feedback potentiometers ASZxx.863.
See Figures 10 and 12.
Set the OPE/MAX/MIN slide switch to MIN. The blue MIN trim potentiometer can now
be gently adjusted to the required minimum position.
See Figures 10 and 12.
Set the OPE/MAX/MIN slide switch to "MAX". The blue MAX trim potentiometer can
now be gently adjusted to the required maximum position. Return the OPE/MAX/MIN
slide switch to OPE.
