9. Connection of pneumatic limit switches for sensing the position of the feed spindle. The unit is delivered
with plastic hose (length 2 meters (6.56 Ft)) with an outside diameter of Ø4 mm (3/16'') for connecting
the pneumatic limit switches. Connection, see Fig. 5 and 7.
Fig. 7.
Hose marked, 1: Pressure supply for both limit switches. To be connected directly to the compressed air
system.
Hose marked, 3: Signal for attainment of the set drilling depth. To be connected to maneuvering valve
V1, port no.12.
Hose marked, 6: Signal indicating that the unit is in the retracted position. To be connected to the start
valve, port no.1
10. Connection of electrical limit switches for sensing the position of the feed spindle. Max. capacity 10A at
125 or 250VAC. The unit is delivered with both microswitches connected to a single cable with a length
of 2 meter (6.56 Ft). Connection, see Fig. 6. and 8.
Fig. 8.
Microswitch M1 for setting forward direction-reverse position when mechanically non-activated:
Cable clolur coding: - Between beige and green = no contact
- Between beige and yellow = contact
When the microswitch is activated at the set direction-reverse position:
Cable clolour coding: - Between beige and green = contact
- Between beige and yellow = no contact
Microswitch M2 is mechanically activated when the feed spindle is in "home position" = fully retracted:
Cable clolur coding: - Between black and blue = no contact
- Between black and brown = contact
- The green/yellow cable is used for earthing.
11. Connection of proximity switches for sensing the position of the feed spindle. The unit is delivered with
both switches and with cable lengths of 2 meter (6.56 Ft). Connection, see Fig. 6 and 9.
Fig. 9.
Proximity switch M1 for setting forward direction-reverse position and M2 when the feed spindle is in
"home position" = fully retracted. Cable colour coding: - Brown = +24V DC
- Black = Signal
- Blue = 0V DC
