Diagnostics - 20 -
POWER REAM
The POWER REAM reports errors using the indicator lights on the user interface
When an error is reported, the indicator light flashes at a rate of 2 flashes per second
Error: When an error occurs during the reaming process; the clamp opens, the lift lowers, and the
diagnosis is shown with the top indicator light in yellow. The light will flash a certain number of times,
pause, then repeat. The error count begins at 2.
Count the number of flashes between the pause and use the following chart to find the cause of the
problem.
2: Closing Fault: the clamp took too long to close.
-Check air inlet pressure
-Check clamp sensor
-Check clamp air lines
-Check clamp solenoid.
-Check clamp cylinder
3: Raising Fault: The lift cylinder took too long to extend from the bottom limit
-Check air inlet pressure
-Check extending needle valve (top needle valve on lift cylinder)
-Check bottom sensor.
-Check lift air lines
-Check lift solenoid.
-Check lift cylinder
4: Extending Fault: The lift cylinder took too long to fully extend.
-Automatic retry; excessive spatter build up in the nozzle (ream more often), or incorrect programmed position of
the nozzle, not allowing reamer to extend to full depth.
-Check air inlet pressure
-Check extending needle valve (top needle valve on lift cylinder)
-Check top sensor.
-Check lift air lines
-Check lift solenoid.
-Check lift cylinder
5: Lowering Fault: The lift cylinder took too long to retract from the top while lowering
-Check air inlet pressure
-Check retracting needle valve (bottom needle valve on lift cylinder)
-Check top sensor.
-Check lift airlines.
-Check lift solenoid.
-Check lift cylinder.
6: Retracting Fault: The lift cylinder took too long to fully retract.
-Check air inlet pressure
-Check retracting needle valve (bottom needle valve on lift cylinder)
-Check bottom sensor.
-Check lift airlines.
-Check lift solenoid.
-Check lift cylinder.
7: Opening Fault: the clamp took too long to open.
-Check air inlet pressure
-Check clamp sensor.
-Check clamp cylinder airlines.
-Check clamp solenoid.
-Check clamp cylinder.
Note: The robot ―start‖ signal may be used to reset an error so that the operator does not have to go
inside the robotic welding cell. For example, if the air supply was not turned on the operator may turn it
on and reset the error by cycling the start output from the robot pendant.
