ABB HESG324436M1/A Analog input module

The GF-1 runs through a function test of the Touch Screen with every start-up. All the IR channels are evaluated and their signal levels compared with those of the initial values. The initial values are determined before the device is delivered and stored in a retentive memory. If one or several channel signals is below a minimum relative to the initial level, this will be indicated on the screen with an error message and the DEF/DIRTY LED will be lit (→ Section 10). A reduced signal level of this kind is normally due to severe contamination of the IR transparent plastic frame which consequently has to be cleaned (→ Section 9.3). 

The Touch Screen, however, remains fully functional. 

Only an increase in the contamination of the screen will lead to the continuous interruptions of one or several IR channels. IR channels that are continuously interrupted will be detected by the touch controller and no longer included in the evaluation. In extreme cases, this may mean that individual zones cannot be activated by touch. CAUTION ! Do not touch the screen whilst the system is being started up, and wait till your application has started.The Touch Screen carries out a function test during the start up in which the signal levels of the IR channels are measured.
