Product description 

3.5.2

 

External device monitoring (EDM) 

The EDM checks if the contactors actually de-energize when the protective device 
responds. If you activate external device monitoring, then the miniTwin2 checks the 
contactors after each interruption to the light path and prior to the machine restart. The 
EDM can so identify if one of the contactors has welded, for instance. In this case the 
external device monitoring places the system in a safe operational state. The OSSDs are 
not re-activated in this case. 

The electrical connection for the external device monitoring is described in section 5.5 
“External device monitoring (EDM)” on page 49. 
Section 6.6 “Configuration of the external device monitoring (EDM)” on page 56 
describes how to configure the function.
