Important - Please Read
Never open the Crack Detector Lane Bench Tester without first removing the AC power.
There is no reason that you should ever have to be inside of the Crack Detector Lane Bench Tester.
Fuse access is outside the box by the power switch.
Always have power off when connecting the Crack Detector Lane Bench Tester to the Crack
Detector Lane under test.
Note: The Crack Detector Lane, or sometimes called Crack Lane or Check Lane is a product of
of Diamond Systems, Diamond Automation, Inc.

How does it work?
Connect the Crack Lane to the test cable. Set the Crack Lane onto the Crack Lane Test Stand.
Turn on Tester and with the special Tapper, or use egg, tap each sensor. When each sensor is
tapped, a yellow indicator will flash. If the sensor being tapped is a first sensor of the group, along
with the yellow indicator, a red indicator will flash. If the sensor being tapped is the last sensor
of a group, along with the yellow indicator, a green indicator will flash. You will soon get a feel
for how little of a tap is required.
What will it find?
If a sensor is dead, no light will turn on as you tap it, or it will always be on, even when not tapped.
If you have to tap the sensor harder then normal to make the yellow indicator come on, that sensor
is defective or the rubber membrane may need replacing. If you tap a sensor and other sensors turn
on, it could mean your tapping way too hard, rubber membrane dried out, sensor's wire touching
other sensors, or defective pre-amp circuit board. If a clock in, red indicator, or clock out, green
indicator fail to flash, but the signal, yellow indicator, flashes, you have a bad pre-amp circuit board
or broken wire. A bonus feature is that you can test, with a good crack lane, Crack Lane Cables.
If one or both of the green indicators -V , +V turns off, there is a electrical short in the Crack Lane
This is just a static tester. How the eggs travel on the lane will effect the Crack Lane performance.

What's a Dead Sensor?
Dead Sensors have no electronics in them, they
are used for egg alignment purposes.

Test Procedure:
Connect Test Cable to the Crack Lane under Test.
Turn the Tester on. The Power +V and -V Indicators will be on.
When tapping a sensor it is important to tap the sensor gently and on the center of
the sensor. You will soon get a feel on how lightly to tap the sensors.
Tap the Group 1 First
sensor, both the Red
Clock In Indicator and the
Yellow Signal Indicator
will flash on each time the
sensor is tapped.
What's Happening!
The Red Clock In Indicator is telling the
electronics that an egg has entered
Group 1.
The Yellow Signal Indicator is telling the
electronics that the egg shell is not
cracked.

Tap the Group 1 Second
sensor, just the Yellow
Signal Indicator will Flash
( shown in picture )
Tap the Group 1 Third
sensor, just the Yellow
Signal Indicator will Flash
Tap the Group 1 Fourth
sensor, just the Yellow
Signal Indicator will Flash
Tap the Group 1 Fifth
sensor, just the Yellow
Signal Indicator will Flash
What's Happening!
The Yellow Signal Indicator is telling the
electronics that the egg shell is not
cracked.

Tap the Group 1 Sixth
sensor, both the Green
Clock Out Indicator and the
Yellow Signal Indicator
will flash on each time the
sensor is tapped.
Perform the same test for
Groups 2, 3 & 4
Why are there 4 Groups?
Because there can be up to
4 eggs on a CD Lane at one
time.
What's Happening!
The Green Clock Out Indicator is telling the
electronics that an egg is leaving
Group 1.
The Yellow Signal Indicator is telling the
electronics that the egg shell is not
cracked.

Trouble Shooting a Crack Detector Lane
When Crack Lane is connected to the Crack Detector Bench Tester, one or
both of the green +V , -V indicators turns off.
1) There is an electrical short inside the Crack Detector Lane.
2) Pre-Amp circuit board inside Crack Lane is defective.
The Crack Detector Lane works on the Crack Detector Bench Tester but
fails in the Grader.
The Crack Detector Lane Bench Tester can only perform a static test. If Crack Detector Lane
works on the Bench Tester, but fails in the Grader, check the following.
1) Check Sensor alignment. Sensor's need to be in a straight row.
Mis-aligned sensors can cause false signals or missing signals.
2) Check Sensor height. If sensor's height are not the same, the egg can bounce
which will cause a poor or missing hit of a sensor.
3) Rubber membrane can be torn, causing moisture into the components of the
Crack Detector Lane. Once moisture is in the inside of the Crack Detector Lane,
it can short out of load down the sensors signals.
4) The seal on the Sensor is broken, and when mositure is high, will load down
or short out the sensor signal.
