4.3 Change of bits
Depending on the additional mounting parts (clutch bearing etc.)
4.4 Connection-Possibilities of the Function Control
Use as air pressure outlet during screw-assembly:
·
to control driver start and stop, as well as shut-off control of clutch;
·
as cycle counter of the complete process;
each in connection with a PE-Switch or similar
This function control is under pressure of appx. 2 bar during actual screw-
driving. After reaching the preset torque, the clutch will disengage and turn off
the Screwdriver. The pressure in the function control line will drop. The
Screwdriver can now be lifted off the assembled screw.
Use as air pressure inlet:
·
If 6.3 bar (90 PSI) air pressure is given to the function control port, the
driver starts rotating at about 15 % of its speed. This will simplify the enga-
gement of bit/socket to fastener (for example when driving hex screws,
nuts, etc.)
If the function control is not needed, the port has to be closed,
otherwise there is a loss of power of about 15 %.
Function Description / Driver Start
Picture: Installation of remote valve
The driver is activated immediately when air is connected. The flow rate of
the remote valve must not be below 2,2 m³/min.
