EDDYSENSOR Operating Manual
The Delay Unit consists of a two-channel shift register based on a
microcontroller. It provides two delayed outputs of the defect signal to use
for processes such as colour marking or sawing and an undelayed output
for immediate switching or warning purposes.
Any defects which occur are stored and, after the expiry of a delay period
(adjustable), they are output. The LEDs on the front panel are used to
indicate defects where the `Defect´ LED flashes immediately to show any
defect that occurs, the `Output 1´ LED indicates that output 1 is activated
and the `Output 2´ indicates that output 2 is activated after the respective
adjustable distance or time delays.
These delays are set using the OUT1 and OUT2 switches on the printed
circuit board. The duration of the delayed signal is set on the WIDTH. The
defect channels are assigned the desired outputs via the `Channel´
switch. There is also a switch on the PCB which is used to select between
ENCODER and TIME depending on whether the application runs with an
encoder or not. The `Encoder´ LED is used to indicate encoder pulses as
they occur if ENCODER has been selected.
