Table  9

  shows  the  standard  configuration  of  the  electrical  interface  (PLC).  For  other  configurations  the 

Levitronix

 shall be used (see reference on title page of this user manual). 

 

Figure 18 

is an example how to connect the 

LEVIFLOW

®

 converter to a relay to control a shutoff valve by a 

digital output. Note that if protective diode is not in the relay, it has to be connected additionally as shown in 

Figure  18

.  This  setup  also  shows  how  to  connect  a  push-button  to  digital  input  (e.g.  for  reset  of  volume 

counter, has to be configured by
