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
