2.7 Pneumatic Connections
Proper operation of the locking mechanism requires a constant supply of clean, dry, non‑lubricated air, with
the following conditions:
•
Pressure range of 60 to 100 psi (4.1 ‑ 6.9 bar) Suggested 80 psi.
•
Filtered minimum: 40 microns.
To lock or unlock the Tool Changer, a constant supply of compressed air is required. If there is a loss of air
pressure in the locked state, the cam profile prevents the master plate and tool plate from unlocking, and the
Tool Changer goes into the fail‑safe condition.
CAUTION:
Do not use the Tool Changer in a fail-safe condition. Damage to the locking
mechanism can occur. Re-establish air pressure and ensure the Tool Changer is in a
secure lock position before returning to normal operations.
2.7.1 Valve Requirements for Air Adapter Modules
NOTICE:
No valve is required when using a valve adapter module. The valve adapter
module has an integrated solenoid valve and only requires the customer to supply a
single air source to the valve adapter.
A customer supplied 2‑position 4‑way or 5‑way valve with either 4‑port or 5‑port configuration
must be used to actuate the locking mechanism in the Master plate. It is imperative that when
air is supplied to the Lock or Unlock Port on the Master plate, 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 may inhibit operation of the
locking mechanism and prevent coupling or uncoupling.
CAUTION:
The locking mechanism will not function properly when connected
to a 3-way valve as this type of valve is incapable of venting trapped air or
vacuum from within the Tool Changer. This could result in damage to the
product, attached tooling, or injury to personnel. Connect the Lock and Unlock
supply air to a 2-position 4-way or 5-way valve with either 4-port or 5-port
configuration.
