Getting started 

3.1.

 

Automatic instrument monitoring 

A  sensor  system  controls  and monitors the proper handling and 
guarantees a monitored  developing  process. In case of failure a 
signal will sound and an error message displayed. For error mes-
sages see chapter 6.8. 

3.2.

 

Checking system functions 

Switch on the instrument. The ADC2 will now show the installed 
firmware version and perform the following checks and tasks: 
1. Initializing the drying module. 
2. Initializing the lift drive. 
If startup was successful the display will show: 

 

* *    ADC2   * *

 

 

SYSTEM READY

 

In this phase, only physical blocking of a drive can cause an error. 
If necessary, check whether there are obstacles in the instrument.
