step 3: reference movement for spindle adjustment
To make the fine adjustment of the spindle for actuator size, it is essential
to move both spindles from the lower to the top end position.
procedure for type 8685:
Actuator with design control function A (CFA, NC):
→
Under maximum control pressure, move the spindles up by acti-
vating the actuator chambers.
→
After the end position is reached (preselected LED is lit), turn off
the control pressure. The spindle moves to the lower end position.
LED for end position Bot is lit with the selected color.
Actuator with design control function B (CFB, NO):
→
Under maximum control pressure, move the spindles down by
activating the actuator chambers.
→
After the end position is reached (preselected LED is lit), turn
off the control pressure. The spindle moves to the upper end
position. The corresponding LED for the end position is lit with
the selected color.
