Contact Recognition
Contacts can be recognized always or only while the engine is running.
Logic Connections
Remote contact input logic connections are made on the BESTlogicPlus screen in BESTCOMSPlus. The
CEM 1 Input 1 logic block is illustrated in Figure 209. The output is true when the CEM-2020 senses a
contact closure and after the activation delay expires. The alarm and pre-alarm logic blocks are similar.
