3.1.2. TEST STATUS OF SENSORS & HOME PHOTOCELL
[READ PHOTOSENSOR]
This function allows for performing the first check of the status of the optical sensor (the software sets
the current of the emitters at 20mA by default) and home photocell.
Useful function for the testing of the boards before mounting on the movement/analysis unit and for an
additional check before closing the instrument with side safety panels.
Procedure:
1.
Select the item ‘READ PHOTOSENSOR’ with the
▲
and ▼ keys
from Select test menu and then
press OK .
2. The instrument is set up for carrying out these tests with the carriage of the reading unit in two
different positions:
- with the reading unit in the home position (on standby)
- with the reading unit in mid-stroke (by initially moving the motor).
As soon as this function is selected the software displays the following request:
-
Press OK to perform the test of the sensors and Home photocell with the carriage of the reading
unit one third along the maximum stroke.
-
Press any key to perform the test in the Home position.
3. The sensors will be displayed in the following format:

4. By performing simple manual operations, like inserting and extracting a test tube from one of the 10
positions in the test tube tray or blacking out the Home photocell, it is possible to check the
functioning.
Press any key to return to the previous menu.
3.1.3. MOTOR TEST

checks that the complete stroke has been carried out in the scheduled time (and preferably without
losing the motor pitch*) as well as checking that the home photocell functions correctly (in the case of
errors the message ERROR READING will appear on the display or the number of STEPS LOST during
the movement will be printed).
Procedure:

he item ‘MOTOR TEST’ from Select test and press
