7.1 Programming with Hand Held Terminal
CAUTION
•
When using HART or a Hand Held Terminal (HHT), a minimum resistance of
250 Ω
must be present in
the loop of the 2-wire system. This is necessary for proper communication (see drawing below). A power
supply of at least
17 Vdc
must be used.
The EJA564E can easily be programmed with the Hand Held Terminal (YHC HART Communicator).
Option 1: HART Hand
H
eld terminal connected across the transmitter.
Option 2: HART Hand
H
eld terminal connected across the loop resistor.
