Fine Adjustment Of The Measuring Transducer; Analog Output - Phoenix Contact MCR-S-1-5-UI-DCI Manual Del Usuario

4.3.7. Fine adjustment of the measuring transducer

After roughly setting the input current range and preselecting the output signal, the module must be closed
and connected to the signal lines and operating voltage following chapter 4.1. "Electrical connection".
When the green LED lights up (operating voltage display) this shows that the operating voltage of
20...30 V DC is connected.
ATTENTION:
When using the MCR-S-1-5-...-DCI,
please be sure to use the signal input
terminal block to suit your measuring
range!
Please adhere to a warm-up phase for
the module of 2 minutes before the
adjustment procedure.
