7. Troubleshooting
Refer to the table below for troubleshooting information:
Symptom
Possible Cause / Correction
Unit will not lock or
unlock
Verify that ball bearings are moving freely. Clean and lubricate as needed (see Tool Changer
Manual Maintenance Section).
Check air supply.
Check that exhaust port is properly vented (check muffler).
Verify that the TSI switch is functioning and properly adjusted.
Verify that the valve power is connected and available (
Valve Power Available
bit is HIGH).
Verify that the Input power is within acceptable limits (
Input and Logic Power Good
bit is HIGH).
Verify that the
Unlatch Enabled
bit is high.
Verify that the valve is operating properly.
Verify that the EtherNet/IP network is operating and communicating properly.
Verify that the Master and Tool are within the specified No-Touch zone when attempting to lock.
Sensors not
operating properly
(but EtherNet/IP is
operating correctly).
Verify that cables are connected correctly.
Verify that the sensors are set correctly (Refer to Tool Changer Manual).
Ensure that the Tool Plate is securely held to the Master Plate, that nothing is trapped between
their surfaces and that there is no air trapped in the Unlock (U) air port.
No or Loss of
Ethernet
Communication
Check/Replace Ethernet cabling up- and down-stream of Tool Changer Modules.
Verify proper EtherNet/IP addressing.
Verify that Input power is connected and available (
Input and Logic Power Good
bit is HIGH).
Inspect EtherNet/IP module contact pins for debris/wear.
Intermittent Ethernet
Communication
problems
Check/replace Ethernet cabling up- and down-stream of Tool Changer Modules
Check if there are collisions reported on the Diagnostics page of the web server. If there are, then
make sure that the switch settings match with the settings of the connected equipment (e.g., If the
device connected to the tool side port is set to Auto Negotiation and Auto Crossover = ON, then
the tool side port on the Tool Changer control module must also be set to Auto Negotiation and
Auto Crossover = ON.).
No power on the
Tool-side
Verify that the LATCH command has been issued by the robot.
Verify that the
Tool Power is ON
bit is HIGH.
Verify that the
Tool Present
bit is HIGH.
Loss of Input power on the Master-side will cause loss of Output Power to the Tool. The Arc
Prevention Circuit relies on Input power to operate. Restore Input Power to the Master to restore
Output Power to Tool.
