2.6 Tool Adapter Assembly Removal
NOTICE:Dependingonmaintenanceorrepairbeingperformed,utilitiestomodulesmayneed
to be disconnected.
Tools required: 5 mm Allen wrench (hex key), 4 mm Allen wrench (hex key)
1. If the Tool Changer is already installed, dock the Tool side of the Tool Changer safely in the tool stand
and uncouple the Tool Changer to allow clear access to the Master and Tool plates of the Tool Changer.
2. Turn off and de-energize all energized circuits (e.g. electrical, air, water, etc.).
3. Remove the control/signal module off the valve adapter. Refer to the control /signal module manual for
instructions.
4. Remove the (2) M5 socket head cap screws and the (2) M6 socket head cap screws and lift the tool
adapter assembly off the Tool Changer or Utility Coupler (refer to Figure 2.4).
2.7 Pneumatic Connections
The air supply used for coupling and uncoupling the Tool Changer or Utility Coupler should be clean,
dry, and non-lubricated. A supply pressure in the range of 60 to 100 psi (4.1–6.9 Bar) is acceptable for
operation of the locking mechanism, with a setting of 80 psi suggested. The air should be ltered 40 micron
or better. A single air supply is require to the valve adapter for Lock and Unlock air, refer to Figure 2.3 for
connection.

2.8 Electrical Connections
The electrical connection for valve control is made through internal pin block as described in Section 1—
Product Overview and detailed in drawings in Section 8—Drawings. The control of the double solenoid
valve is integrated with an ATI-supplied control/signal module that is piggy-backed onto the valve adapter.
3. Operation
Latch and Unlatch commands sent to the control/signal module are pass through the solenoid cable to control
the solenoid valve providing lock and unlock air to the Tool Changer. The control/signal module can provide a
customer specied safety functionality to prevent the accidental unlock of the Tool Changer unless the Tool is
nested in the tool stand. Depending on the functionality of the control/signal module, the ability to unlock the Tool
Changer unless the tool is coupled and in the tool stand may be denied. When this is the case the manual override
is provides on the valve adapter, refer to Section 5.1.1—Solenoid Valve Manual Override Procedure. Use of the
manual override should be restricted to contingency situations and only when the robot and tool are in the stand or
storage location. Actuation of the Unlatch valve manual override will result in Tool Changer release.

It is important that the valve adapter be supplied with clean, dry, non-lubricated air supplied between 60 and 100
psi (4.5–6.9 Bar) and ltered at 40 microns or better. Valve adapters are supplied with the Tool Changer to provide
a fully integrated solution. The customer is only required to supply the valve adapter with a single air supply.
