– Fault Messages
“Green sensor failure”
Explanation: A green or green constant sensor has stayed on from the end of one Ready signal to
the beginning of the Ready signal for the next stroke. No stroke angle is shown with
this fault.
Remedy: Check for a shorted sensor. Make sure the Ready signal has been set correctly.
Check to see if a press or equipment malfunction is causing the sensor to stay on–
for instance, a part wedged against a sensor or a pinched wire.
“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 5-30.
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.
