User Manual MIC 900 / MIC 1100 / MIC 3000
The controller also allows you to enter negative temperature values:
- In order to pre-program negative nominal values in a step, the installation manufacturer
has to pre-program negative nominal value limits for chamber and core.
- „0“ can be entered as a nominal value. The nominal value „Off“ is shown for chamber
and core when a new program step is pre-programmed. . This means: the nominal value
is deactivated. As soon as a value is entered (even if it is „0“) the nominal value counts
as activated. If you want to deactivate the nominal value later in the step, press
the „Off“ button.
1.4.1 MIC3000 Control buttons (number buttons)
Text can also be entered via the operation buttons 0 – 9. Select which value you want to enter via the
cursor buttons and then change into entry mode by pressing the Return button. Now use the operation
buttons on the numerical pad to enter your value and confirm your entry by pressing Return.
1.4.2 Screen lock
When you press the „Enter“ button for 3 seconds, all buttons and touch function on the display will be
locked. On the bottom edge of the display you will see the lock symbol.
In order to de-activate the lock, press the „Enter“ button for about 5 seconds.
A program run is not affected by a button/keypad lock. This means that the program will
continue as normal, even if the keypad lock is activated while a program is in operation.
Neither the communication with VisuNet nor the service program are affected when a keypad
lock is activated. Programs can be started and stopped via VisuNet even if the keypad is
locked.
The function is mainly needed while the installation and the controller are being cleaned.
