Passwords and Operating Levels
The operation of the freezer is divided into 3 levels protected by pass-codes. A pass code is a
combination of keys that must be pressed at the same time in order to enable access to pass-code
protected functions.
The pass codes will be handed over in a separate envelope. Before running the unit you must
consider who should be entitled to enter the higher levels of operation and distribute the pass codes
accordingly.
First Level
– Operator Level
In this level the daily operation of the freezer is allowed, for instance start pumps, dasher and
compressor as well as activating the CIP function. Access to Set up and Maintenance is not allowed.
Second Level
– Super User Level
When this level is activated by means of entering the correct pass-code there is access to the Set Up
menu where it is possible to adjust parameters related to the function of the freezer. There is also
access to the Maintenance Menu where it is possible to see the status and function of the In- and
outputs of the PLC.
When leaving the Set Up Manu the user will be prompted to disable the password. If he chooses not
to do so, the pass-code will automatically be disabled after 10 minutes.
Third Level
– Master Level
When this level is activated by means of entering the correct pass Code is it possible to manually
operate the Digital and analog outputs of the PLC and thus check if they are working correctly. Please
note that the super user Level must be enabled before the master Level can be selected.
In order to leave the Master Level the Pass Code must be disabled. This is done by keying in the right
key combination once again.
