TROUBLESHOOTING
An incorrect setting on the CDP-01 is often the cause for incorrect or unwanted guiding
characteristics. Faults and the procedures for rectifying the faults are described in more detail in
the CDP-01 Reference Manual,
Chapter ‘Frequent Setting Errors’ . Application-specific faults are
explained below.
Note:
In Auto mode, the mandrel is supposed to move (chase) the same direction as the test
strip.
Fault Diagnosis - Fault Rectification
Fault: In Automatic mode, the mandrel moves in the wrong direction to end of stroke.
Remedy: Select ‘Manual’ mode and change the polarity (guide direction) in the appropriate
sensor mode (LEDs 9 or 10 or 9 & 10 lit).
Reference: CDP-01 Reference Manual, section: “Changing the Guide Direction”
Fault: In Servo Center mode, the mandrel moves to either end of the stroke instead of to the
center of its stroke.
Remedy: Select ‘Manual’ mode and change the servo-center polarity.
Reference: CDP-01 Reference Manual, section: “Servo Center Polarity”.
Fault: In Automatic mode, the mandrel does not accurately follow the sensor.
Remedy: Perform the procedure “Start-up / Sensor Bandwidth To Mandrel Ratio Calibration”
found in this document.
Fault: In Automatic mode, the mandrel follows the strip, but in the wrong direction.
Remedy: Perform the procedure “Start-up / Position Transducer Calibration” again, but reverse
the directions of movement for the mandrel in the steps just before pressing ‘F1’ and
‘F2’ keys.
Fault: While guiding, the mandrel hunts back and forth excessively.
Remedy: Reduce System Gain or if the strip is slipping across face of deflector roll, increase
traction through deflector.
