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, p age 38 ).
