Definition

REMOTE SETPOINT SOURCE— This selection determines what your remote setpoint source will be when

toggled by the SETPOINT SELECT or Digital Input.

NONE— No remote setpoint,

INPUT 2— Remote Setpoint is Input 2.

INPUT ALGORITHM 1— Remote Setpoint using Input 1 algorithm.

INPUT ALGORITHM 2— Remote Setpoint using Input 2 algorithm.

INP 3— Remote Setpoint is Input 3.

ATTENTION To cycle through the available local setpoints and remote setpoint, press and hold in the [SETPOINT SELECT] key. When the key is released, the setpoint selection currently displayed will be the new setpoint selection.

AUTO BIAS is used for bumpless transfer when transferring from local setpoint to remote setpoint. Auto Bias calculates and adds a bias to the remote setpoint input each time a transfer is made. Available for any analog input RSP source and if no tracking is selected.

ENABLE— Enables auto bias.

DISABLE— Disables auto bias.

SETPOINT TRACKING— The local setpoint can be configured to track either PV or RSP as listed below. Not configurable when Auto Bias is set.

ATTENTION For selections other than NONE, LSP is stored in nonvolatile memory only when there is a mode change; i.e., when switching from RSP to LSP or from Manual to Automatic. If power is lost, then the current LSP value is also lost.

NO TRACKING— If local setpoint tracking is not configured, the LSP will not be altered when transfer from RSP to LSP is made.

PV— Local setpoint tracks the PV when in manual mode.

RSP— Local setpoint tracks remote setpoint. When the controller transfers out of remote setpoint, the last value of the remote setpoint (RSP) is inserted into the local setpoint.

SETPOINT HIGH LIMIT*— This selection prevents the local and remote setpoints from going above the value selected here. The setting must be equal or less than the upper range of the inputs.

SETPOINT LOW LIMIT*— This selection prevents the local and remote setpoints from going below the value selected here. The setting must be equal or greater than the lower range of the inputs.

CONTROL OUTPUT DIRECTION— Select direct or reverse acting control.

DIRECT ACTING CONTROL— The controller's output increases as the process variable increases.
