Thermo WX 80 Ultraspeed Refrigerated Centrifuge Access Control System

Summary

This access control is used to restrict the access to a certain number of users of the centrifuge. The users are required to log on to the centrifuge by inputting the ID code and the password on the initial screen to operate the centrifuge.
Before using the access control, carefully read through both: this instruction manual and the instruction manual of the centrifuge. This system distinguishes between the system administrator and the registered user. Up to 3 system administrators and up to 37 users can be registered.
The system administrator is permitted to:

Register, change, and delete the registered users
Refer to the ID codes and passwords of the system administrators and the registered users on the user list screen, and
Utilize the printout function by means of the optional printer.

The registered users are:

Permitted to log on to the centrifuge by inputting an ID code and a password in the specified boxes on the initial screen to operate the centrifuge, but
Not permitted to refer to the user list screen nor to utilize the printout function.

Both: the system administrators and the registered users can turn off the centrifuge power or log off the centrifuge while the vacuum pump is turned off or the rotor is stopping after operation. The display turns to the initial screen of the access control when the centrifuge is logged off.
