6.5 How to check speed sensor for functioning
Check the functioning of the speed sensor as follows:
1. Switch on the computer (<ON/OFF>-key);
2. Using a screwdriver or other metal mass, pass over the red part of the sensor
repeatedly. If the computer displays the simulated speed (which probably will not
be constant) it means that the sensor is functioning and is properly connected.
6.6 How to check photocells for functioning
Check the functioning of the photocells as follows:
Simulated test:
With one of your fingers or with a small object, pass in front of each photocell: if the
photocell is correctly connected, it will send impulses to the monitor, which will
activate an audible alarm together with the switching on of the led corresponding to
the row.
After a few seconds the led will switch off and the audible alarm will go out. Repeat
the test with the next photocell.
N.B.:
it is necessary to wait for the led to switch off again.
Execute this operation on each photocell.
Real test:
If possible, execute a real test using the seeds that will be used afterwards; this will
guarantee a proper functioning while sowing.
