Switching Between Remote and Local
Setpoints
Switch from the RSP, CSP or ESP mode to the LSP mode by using an
external digital signal
or
switch manually, using the R (remote) button.
Manual switching via the R (remote) button always overrides the
digital signal or RS-485 signal. Remote/Local switching occurs only if
the controller is in the Remote mode.
Changing Configured Values: Ratio,
Bias and Extra Internal Setpoint
The RSP input value received at Al2 can be configured to be modified
before being used as the controller's RSP.

FCODE 120 _ FCODE 1 FCODEZ __
Use FCODE 1 and 2 to adjust the ratio and bias values used in
conjunction with the RSP or the internal calculation functions (FCODE
107 and 108). Both values reside within the controller configuration
parameters; therefore the user must enter the configuration mode to
change these values. Press the PROG button to enter the
configuration program. Then use the TUNE button to advance to the
appropriate FCODE. After each FCODE number, the controller
indicates the current value stored. Use the increase/decrease buttons
(11) to change the value. Press the flashing R button to save the new
value.
