Configuration
(FISHER'J
When the controller configuration is fully planned, enter the
configuration options and the tuning parameters. Press the PROG
button to access the configuration mode. The controller is designed to
prompt the user for easy configuration entry. Use the TUNE, and
green increase/decrease buttons, to call the appropriate FCODE's,
select and enter the functions, and set the tuning parameters.
5.4
Set the measuring range and fix the position of the
decimal point in the digital display, using FCODE
24, 25 and 26 before changing any parameter.
Many parameters use the measuring range limits
as a reference. If the measuring range is altered,
the limits and alarms that refer to the measuring
range adjust automatically. This eliminates the
need for further adjustments.

Input Signal Assignment
Some input and output signals have definite functions; (e.g. All is
always the process value [PV] input). Other signals, such as Al3, Al4
and DII, D12 can have any one of the assignments shown. The user
assigns one of these options to the signal line, then chooses the valid
signal range and type of input that indicates the active discrete signal.
