3. Operation
Air modules pass air utilities from the Master to the Tool for use by the customer’s tooling. Unlike pass-through
ports, self-sealing valves prevent the air circuits from discharging, which eliminates the need to close upstream
circuits. Self-sealing valves and pass-through ports operate at a maximum pressure of 100 psi (6.9 bar).
NOTICE: If the air pressure is not released from the Tool side of the pass-through port, debris can be
expelled at high velocity when the Tool Changer uncouples. Take all required safety precautions.
4. Maintenance
Perform maintenance to maximize the operational life of the module.
WARNING: Do not perform maintenance or repair(s) on the Tool Changer or modules unless
the Tool is safely supported or placed in the tool stand, all energized circuits (e.g. electrical,
air, water, etc.) are turned off, pressurized connections are purged and power is discharged
from circuits in accordance with the customer’s safety practices and policies. Injury or
equipment damage can occur with the Tool not placed and energized circuits on. Place the
Tool in the tool stand, turn off and discharge all energized circuits, purge all pressurized
connections, and verify all circuits are de-energized before performing maintenance or
repair(s) on the Tool Changer or modules.
A preventive maintenance schedule and checklist are provided in the following tables:
Table 4.1—Preventive Maintenance Schedule
Inspection Schedule Action Required
Weekly Clean and inspect
6 months or 500,000 cycles Seal replacement
Table 4.2—Checklist
Weekly Maintenance:
г Clean mating surfaces. Use a vacuum to remove any debris and clean in and around the
mating surfaces of the modules using a nylon brush (ATI Part Number 3690-0000064-60).
Lubricate seals periodically with Magnalube G lubricant.
г Inspect modules for air leaks. Replace components as necessary.
6 months or 500,000 cycle Maintenance:
г Remove and replace self-sealing valve O-ring seals in the both the Master and Tool Module.
During O-ring and seal replacement inspect valve stem and dowel pin for straightness. During
O-ring and seal replacement re-lubricate bores. Refer to Section 5.2.1—Master Side Self
Sealing Valve and Section 5.2.2—Tool Side Self Sealing Valve.
г Inspect the mounting fasteners for tightness, tighten if loose refer to Section 2.1—Module
Installation.
