4. Maintenance
Once installed, the operation of the control modules are generally trouble free. The modules are not designed to be
eld serviced as all point-to-point wiring connections are soldered. Component replacement is limited to the V-ring
seal on the Master.
DANGER: This module has a voltage of 50 V or greater; NO contact should be attempted
before removing power. This especially includes separation or insertion of the mating
connectors or any contact with the Tool Changer, Utility Coupler, or its components. Arcing
and damage will occur if this is not observed. Remove power before attaching, disconnecting
any cables or attempting any maintenance of Tool Changer or Utility Coupler.
WARNING: Do not perform maintenance or repair on 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 purged and power discharged from
circuits in accordance with the customer’s safety practices and policies. Injury or equipment
damage can occur with Tool not placed and energized circuits on. Place the Tool safely in the
tool stand, turn off and discharge all energized circuits, purge all pressurized connections,
verify all energized circuits are de-energized before performing maintenance or repair on Tool
Changer or modules.
If the Tool Changer is being used in dirty environments (e.g., welding or deburring applications), care should be
taken to limit the exposure of the Tool Changer. Idle Tool assemblies should be covered to prevent debris from
settling on the mating surface. Also, the Master assembly should be exposed for only a short period of time during
Tool change and down time.
Under normal conditions, no special maintenance is necessary; however, it is recommended that periodic
inspections be performed to assure long-lasting performance and verify that unexpected damage has not occurred.
Perform the following visual inspection monthly:
• Inspect mounting fasteners to verify they are tight and if loose; then tighten to the proper torque. Refer to
Section2—Installation.
• Cable connections should be inspected during maintenance periods to ensure they are secure. Loose
connections should be cleaned and re-tightened as appropriate. Inspect cable sheathing for damage, repair or
replace damaged cabling. Loose connections or damaged cabling are not expected and may indicate improper
routing and/or strain relieving.
• Inspect the Master and Tool pin blocks for any pin damage, debris or darkened pins. Refer to Section4.1—Pin
BlockInspectionandCleaning.
• Inspect V-ring seals for wear, abrasion, and cuts. If worn or damaged, replace. Refer to Section5.2.1—Seal
Replacement.
