Fault Messages 7-29
“Green constant fault”
Problem:
A green constant sensor was not on at the beginning of its Ready signal or turned
off during the 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”
Problem:
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”
Problem:
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”
Problem:
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.
