“Green constant fault”
Explanation:
A green constant sensor turned off during its Ready signal. Green
constant sensors must stay on throughout the Ready signal. The angle at
which the sensor turned off is displayed.
Remedy:
Check for the malfunction that the sensor was supposed to detect.
If no malfunction has occurred, check to make sure that the Ready signal
is set properly. Remember, for green constant sensors, the Ready signal
must be a little shorter than the sensor’s actuation angle. Check that a
sensor is actually plugged into this input. Check connections between the
DSI 2 and the controller.
“Green quick check sensor actuated outside ready”
Explanation:
A green quick check sensor actuated or stayed on outside the Ready
signal. The stroke angle at which the sensor was first detected on outside
the Ready signal is shown.
Remedy:
Check for the malfunction the sensor was supposed to detect (part ejection
problem, misfeed, etc.). Check for a part wedged against the sensor, a
shorted sensor, a pinched wire, or other cause that would keep the sensor
on or cause it to go on outside its Ready signal. Make sure the Ready
signal is set correctly.
“Green special fault”
Explanation:
A green special sensor did not actuate (i.e., there was no contact closure to
ground) within the maximum number of strokes set in Program mode.
Remedy: Check for the press or equipment malfunction that the sensor was
supposed to detect. Check for any cause that would keep the sensor from
going on. Make sure the maximum stroke count is set correctly, especially
that it is not set too low. See Setting the Counter Value for a Green
Special Sensor, page 5-29.
Fault message for yellow sensors “This N/O sensor is grounded”
Explanation:
A yellow sensor turned on (i.e., there was a contact closure to ground).
When this message is displayed, the angle at which the condition was
detected is shown.
Remedy: Check for the press or equipment malfunction that the sensor was
supposed to detect. If no malfunction has occurred, check for a shorted
sensor or pinched wire.
