All the FCI transmitters that incorporate the HART protocol are set at the factory to polling address “0”. Users
should reset the polling address to match the needs of their network.

At polling address “0”, the GF90/GF92 outputs a current of 4 - 20mA; at any other polling address, the GF90/GF92
outputs a fixed 4mA current; in compliance with the HART standard. A digital signal is provided with all polling
addresses.

If the GF90/GF92is going to be used as a HART network transmitter, the polling address needs to be changed to
other than “0”. The power supply feeding the network must provide sufficient current to support the instruments in
the network.
