Valve Requirements and Connections
Pneumatic Connections
As with all pneumatic piston arrangements, smooth operation re-
quires proper porting of the supplied and vented air. It is recom-
mended that a single 4-way valve be used to actuate the locking
mechanism in the SWK. The valve may be of either 4-port or 5-port
configuration. It is imperative that when air is supplied to the Lock
or Unlock Port on the SWK, that the opposite port be vented to
atmosphere (i.e., when air is supplied to the Lock Port, the Unlock
Port must be open to the atmosphere.) Failure to vent trapped air
or vacuum on the inactive port will negate the locking force of the
Tool Changer mechanism. The Lock and Unlock Ports are threaded
for M3 connections.
NOTICE
The Tool Changer locking mechanism will not function properly
when connected to a single 3-way valve as this type of valve is
incapable of venting trapped air pressure from within the Tool
Changer.
Connect the Lock and Unlock supply air to a single 4-way valve
with either 4 or 5 port configuration.
