4.1.5  Installation of PLC Interface for Extended Controller LPC-2000.2 

To operate the pump system with a PLC, a minimum set of two digital inputs and one analog input is needed. 
The digital and analog outputs can be used to monitor the pump status and operating parameters. 
 

 

CAUTION 

 

The  analog  inputs  and  outputs  are  not  galvanic  isolated  from  the 
controller  electronics.  To  avoid  ground  loops  and  mal-functions,  use 
floating analog signals. 

 

1. 

Detach the PLC connector from the controller 

2. 

Connect  the  designated  wires  of  a  cable  the  pins  of  the  detached  connector  according  to 

Table  14. 

Assignment  and  functions  of the  I/Os  can  be  changed  with  the  controller  firmware 

version (refer to according firmware documentation). 

3. 

Connect the PLC connector (

Figure 27

) to the controller.
