Adjusting
10.1
Entering the rotor type
It is necessary to enter the rotor type used (12-place or 24-place) in order to calculate the filling volume.
It is only possible to enter the rotor type when the rotor has stopped.
To adjust the settings:
−
Go into the system settings (start screen, cha. 8.2, pos. 2)
−
Change to the actual used and inserted rotor-type, 12-place or 24-place (cha. 8.5, pos. 8)
−
Save the done settings and go back to the start-screen with the button save changes (cha. 8.5, pos. 1)
10.2
Calibrating the filling volume
•
Go into the system settings (start screen, cha. 8.2, pos. 2)
•
Go into the service menu (system settings, cha. 8.5, pos. 2)
•
Go into the calibration (service menu, cha. 8.6, pos. 1)
•
Open the lid (cha. 8.6.1, pos. 1)
•
Check that the 36ml target (cha. 8.6.1, pos. 6) is green for use a 50ml graduated measuring cylinder,
conform to DIN/EN XXXX and equivalent the 72ml target for a 100ml cylinder
•
Remove the rotor and hold a cup underneath the injection-tube and push the button fill in solution (cha.
8.6.1, pos. 2) and take attention that no air-bubbles are into the solution-tube at the back-side of the lid
(fig.7.1, pos. A)
•
hold a cylinder underneath the injection-tube inside from the lid and push the button start calibration (cha.
8.6.1, pos.3)
•
Adjust the reading from the
cylinder at the target measure (cha. 8.6.1, pos. 8) with the buttons “+” or “-“
graduate decimal point 0.1ml and “++” or equivalent “- -“ graduate decimal point 1ml
•
Accept the calibration with the button XXXX or go back to the service menu (cha. 8.6.1, pos. 4)
•
If it was necessary to adjust the calibration, then check the calibration again.
Do a calibration-check
−
monthly
−
befor a validation
−
after a maintenance
10.3
Audible signal
•
2 second intervals if an error occurs
•
in 10 second intervals after the program has ended and the rotor has stopped.
The audible signal can be stopped by opening the lid or by pushing any button.
The signal after completion of the program can be activated or deactivated in the following manner, if the rotor is at
standstill:
-
To adjust the volume go at the start screen and push the button for the system settings (cha. 8.2, pos. 2)
-
Adjust the volume by varying the slider at the bar (cha. 8.5, pos. 6), at the totally left side the audible signal
is deactivated
-
Select your preferred mode for the audible signal after the program is ended with only one beep or with an
endless interval of 10 seconds during one hour
-
confirm it with the button save changes (cha. 8.5, pos. 1)
If an alarm or the program-end beep is running then the Stand-by mode will activate till after 60 minutes
insead of the normal 10 minutes, but the display will go to the dark-mode after 10minutes
