Checkline LS-REGSENSOR - Manual

Mark•Ey e™ SETUP INSTRUCTIONS
W eb color/background is Lighter than the mark (See Figure A)
P osition the detection zone of the sensor between the registration marks and press the “LIGHTER
THAN MARK” button to initiate the AUTOSET™ routine.
The green LED AUTOSET™ indicator will rapidly blink until the proper setting is achieved. The red LED
output indicator and output transistors will turn “OFF”. When the mark passes through the detection
zone, the red LED output indicator and output transistors will turn “ON” for the duration of time that the
mark is in view.
NO TE: Detection of a Dar k colored mark on a light colored background is impossible if the light source can
not penetrate through the light colored background. If this condition occurs during a light colored
background AUTOSET™ routine, both the red and green LEDs will flash twice.
W eb color/background is Darker than the mark (See Figure B)
P osition the detection zone of the sensor between the registration marks and press the “DARKER
THAN MARK” button to initiate the AUTOSET™ routine.
The green LED AUTOSET™ indicator will rapidly blink until the proper setting is achieved. The red LED
output indicator and output transistors will turn “OFF”. When the mark passes through the detection
zone, the red LED output indicator and output transistors will turn “ON” for the duration of time that
the mark is in view.
In verting the Output
Depress both b uttons for 3 seconds.
Pulse Stretc her
The Mar keye sensor can be programmed to provide a 15-millisecond pulse stretcher timing function.
To determine if the pulse stretcher is enabled, during initial power-up the AUTOSET™ LED will rapidly
flash twice, verifying that the pulse stretcher is enabled.
Enab ling or Disabling the Pulse Stretcher
T o toggle the status of the pulse stretcher to the opposite state:
1. Remove power from the sensor.
2. Depress and hold both buttons simultaneously and apply power.
3. After applying power, note that the AUTOSET™ LED will flash; release both buttons.
4. Depress the “LIGHTER THAN MARK” to toggle the pulse stretcher to the opposite state.
5. Remove power from the sensor.
6. Whenever power is applied, the pulse stretcher will be enabled and the AUTOSET™ LED will flash
twice. The pulse stretcher can be disabled when these steps are repeated.
NO TE: The f actory’s default setting for the pulse stretcher is the disabled state.
