Setting The Mechanical Digital Feedback With Proximity Switches; Setting The Mechanical Digital Feedback With Microswitches For 24 V - ABB PositionMaster EDP300 Operating Instruction

5.4.2 Setting the mechanical digital feedback with
proximity switches
1. Loosen the screws for the housing cover and remove it.
CAUTION – Risk of injury!
The device includes slot sensors with sharp
edges. Only adjust slot sensors using a
screwdriver.
2. Set the upper and lower switching points for digital
feedback as follows:
— Select "Manual Adjustment" mode and move the valve
by hand into the lower switching position.
— Use a screwdriver to adjust the slot sensor for proximity
switch 1 (lower contact) on the feedback shaft until it
closes the contact (i.e., until shortly before entering the
proximity switch). The slot sensor enters proximity
switch 1 when the feedback shaft is rotated clockwise
(as viewed from the front).
— Move the valve by hand into the upper switching
position.
— Use a screwdriver to adjust the slot sensor for proximity
switch 2 (upper contact) on the feedback shaft until it
closes the contact (i.e., until shortly before entering the
proximity switch). The slot sensor enters proximity
switch 2 when the feedback shaft is rotated counter-
clockwise (as viewed from the front).
3. Attach the housing cover and screw it on to the housing.
4. Tighten the screws so that they are hand-tight.
