51
Spin2000
E06
A/D time out reading vacuum
Missed vacuum reading
E07
Motor exceeded maximum RPM
Shut down spin processor
E08
No RPM feedback. Zero RPM
Shut down spin processor,
remove any restriction to
rotation
E10
Purge Air pressure below setpoint.
Will not start new process.
Will shut down spin processor
Check “Seal Purge” hookup
and pressure (SEC 3.2.3)
Certain errors will cause the motor to shut down. The timer will stop. Pressing the
F1
key clears errors and pressing the
RUN
key will restart the program at the point it was
shut down. If you desire to restart the program from the beginning, press the
F1
key
twice, then press the
RUN
key to start.
If an error condition occurs, check the following:
•
Record the time, conditions, program number, program step, and error code
•
Determine if error is due to vacuum loss or motor speed. Correct any obvious
problems
•
If condition persists, contact Support at Laurell Technologies Corporation for
assistance
•
Vacuum source
•
Seal Purge source pressure >60 PSI required
•
Lock out power supply and turn chuck by hand making note of any excessive
drag
Note: Mechanical intervention during rotation is not permitted with this
equipment design and damage caused is not covered by our warranty.
4.1.1 VACUUM LOSS (On units equipped with vacuum sensor only.)
•
Vacuum readings >20” Hg typically indicate sufficient vacuum hold is present.
<15” Hg vacuum (factory setpoint) is normally considered insufficient to operate
safely. A flashing
“V=XX”
display is an insufficient vacuum indicator where
XX
is
the actual vacuum value being read by sensor.
Note: the vacuum setpoint can be changed (contact the factory for the adjustment
procedure)
4.1.2 REMOVING, CLEANING AND INSTALLING THE VACUUM VALVE
•
The vacuum valve is an air operated valve with an internal piston. Chemicals
such as photoresist or polyimides, which enter into the vacuum path, can prevent
this piston from moving. The piston will fail to operate due to chemical
contamination. If this happens and it is obvious that the vacuum valve is not
