Autofib 2 Fault - Failure To Pick Up Fibre (DE)
Description
It is possible the Autofib is losing its air supply . ICL will give
an error 'failure to put down fibre'. A quick check of this is described
below.
Try
The following steps act as a guide.
-
Firstly the TO already should have be able to tell you if the gripper
is working, by listening to the gripper when waking the robot. I.e.
-
Sleep the robot
-
Wake the robot
-
As Autofib goes through the wake process, the gripper can be heard to
open and close. If the gripper can not be heard to open and close,
then there most likely an air leak. Check that there is at least
6 Kgf/cm2 pressure to Autofib.
-
Check that the air solenoid is operating during the wake procedure.
The air solenoid has a red LED on it to indicate operation. It is located
inside the Autofib robot, at the bottom left corner. See "Removal
of Fibre Module" webpage.
-
Other problems could be failure of the solenoid, failure of the gripper
mechanism, failure of the control electronics.
-
It is important that if the mechanism fails during a setup and is then
repaired, that the fibre that it failed on is recovered. If it is not recovered,
then damage could be done to the fibres. See the documentation on recovering
a "Lost Fibre" for further information.
If you are still having problems then call the appropriate AF2
expert.
