Reject Confirm
Reject confirm will require external hardware which may not be installed on your system. Contact Goring Kerr for
assistance.
This option permits the reject device response to be automatically monitored by the detector. Select from the following
options:
No reject confirm
One sensor
Two sensor (this option monitors both strokes of the reject device)
Polarity (inverts the polarity of the incoming signal)
Confirm time (adjust the reject confirm signal window)
Learn (this allows the detector to automatically learn the reject response time)
Reject Confirm Setup
One Sensor
The reject confirm system continuously monitors the signal reflected back from the reject device generated by a reject
confirm switch. The time delay between the initiation of a rejection signal and the returned confirmation signal is
monitored to confirm that the reject device operated within a prescribed time period. Once the wiring of the switch has
been completed, from reject confirm menu (Path: Rejects/Setup Timing/Special/Reject Confirm) press the Test button to
enter the switch test menu. Press Test Reject and make sure the sensor state changes in conjunction with the reject
activation. If this is true, the signal is reaching the DSP control. Press Exit to get back to the reject confirm window;
press the Learn soft key and follow the on-screen instructions. This process will train the system so that the normal
response time for the reject confirm signal is established. This can be manually adjusted if necessary using the Confirm
Time soft key and the Reject Confirm menu.
Two Sensors
The system can be configured to monitor not only the reject response time, but also the time taken to return to normal
position. This option will require that two sensors be used in such a way that both strokes of the reject can be
monitored. Contact Goring Kerr for assistance in using this feature.
Suppression
This feature is designed to reduce false triggering caused by the action of the reject device.
