24) adjust the rotation verse of the filter wheel going to the screen hardware test, pressing in
sequence the keys F5 (service), F3 (Diagnostics) and again F3 (hardware test) starting from the
main menu, and then evidence the line FS (filter wheel) from the motor’s table using the arrows
up and down.
Press the key F1 (zero motor) to execute a research of the filter wheel zero which should stop
with the hole marked 0 between the two arms of the transmission chain which is situated
behind it.
Move the cursor to the column “pos.log.” using the key Enter and then digit 1, the filter wheel
should rotate in clockwise for more then one round positioning the hole marked 1 to the
position where the hole marked 1 was positioned before. If this is not the case, i.e. the filter
wheel is moving in the contrary verse disconnect the connector of the cabling noted with MFS,
exchange between them the cables of blue colour, reconnect the connector and repeat this
point from the beginning to verify that the rotation sense has been effectively changed.
25) adjust the rotation verse of the peristaltic pump going into the screen hardware test,
pressing in sequence the keys F5 (service), F3 (diagnostics) and again F3 (hardware test)
starting from the main menu and then evidence the line PM (peristaltic pump) of the motor’s
table using the arrows up and down.
Press the key F2 (motor ahead) and the reel of the peristaltic pump should rotate in
anticlockwise sense for about 1 / 2 round. If this is not the case, i.e. the reel is moving in the
contrary sense, disconnect the connector of the cabling with the note MPM, exchange
between them the two blue colour cables, reconnect the connector and repeat this point from
the beginning to verify that the rotation sense has been effectively changed.
26) adjust the movement sense of the dilutor using the screen hardware test, pressing in
sequence the keys F5(service), F3 (diagnostics) and again F5 (hardware test) starting from the
main menu and then evidence the line DS (diluter) of the motor’s table using the arrows up and
down.
Press the key F1 (zero motor) to execute a research of the piston zero of the diluter which should
stop all in high, without the instrument signing errors (beep). If this is not the case, i.e. the piston
stops all down and / or an error is signed, disconnect the connector with the note MDS,
exchange between them the two blue coloured cables, reconnect the connector and repeat
this point from the beginning to verify if the movement has been effectively corrected.
27) adjust the rotation sense of the reagent plate using the screen of hardware test, pressing in
sequence the keys F5 (service), F3 (diagnostics) and again F3 (hardware test) starting from the
main menu and then evidence the line RP (reagent plate) of the motor’s table using the arrows
up and down.
Press the key F1 (zero motor) to execute a research of the reagent plate zero which should stop
with the needle arm in correspondence of the left side of the instrument without the instrument
is signing an error (beep). If this is not the case, i.e. the plate is rotating in the contrary sense and
/ or an error is signed, disconnect the connector of the cabling with the note MRP, exchange
between them the two blue coloured cables, reconnect the connector and repeat this point
the verify that the rotation sense has been effectively changed.
