Remote And Local Setpoint Operation

The controller setpoint mode can be switched between Local Setpoint

operation and Remote Setpoint operation. In the Hidden Function Mode, the
“SPSL” parameter allows the operator to select the desired setpoint operating
mode. To allow front panel switching between setpoint modes, program the
setpoint select parameter (SPSL) to “Enbl” in the Lockout Module. The user
input or RS485 serial interface option may also be used to perform the
setpoint selection function, independent of the setting in the Lockout
Module. Front panel annunciator REM is

on

for Remote setpoint operation

and is

off

for Local setpoint operation. When transferring the controller mode

from/to the setpoint modes, various controller response options are available
(see

SPtr parameter, page 38

).
