Notes:
1. In case, that output signal from the capacitive transmitter (wiring diagram Z241a) is not used (incomplete
circuit between terminal 81 and 82), it is required to connect terminals 81 and 82 by jumper (jumper is connected
at manufacturing plant for connecting to terminal board only). By using output current signal from capacitive
transmitter it is needed to remove jumper.
2. For the EA version with feeding voltage 24 V AC is not needed to connect ground wire PE.
3. In the version equipped with the controller device while using the feedback from transducer CPT; when using
the output signal there has been no galvanic isolation of the signal from the input one!
4. In case that galvanically separated output signal is needed it is necessary to use galvanical separation
element (is not part of delivery), e.g. NMLSG.U07/B (producer SAMO Automation s.r.o.). After discussion this
module could be supplied by EA producer.
