LOCAL BIAS Field
This field specifies the local bias value for the FCM. The configured entry is the
initial local bias. During runtime, you can enter the local bias value at the console.
Valid entry is a decimal value.
LIMITED BIAS MODES Field
This field specifies the bias limits applied to the bias modes. Valid entries are:
NONE
LOC limits apply to the local bias mode
REM limits apply to the remote bias mode
LOC/REM limits apply to local and remote bias modes
BIAS HIGH LIMIT Field
This field specifies the high limit for the bias values. This limit only applies to the
bias modes specified in the LIMITED BIAS MODES field.Valid entry is a
percentage value.
BIAS LOW LIMIT Field
This field specifies the low limit for the bias values. This limit only applies to the
bias modes specified in the LIMITED BIAS MODES field. Valid entry is a
percentage value.
RATIO MODE Field
This field specifies which remote setpoint ratio value the controller is presently
using. The configured entry is the initial ratio mode. During runtime, the contents of
this field change each time the mode is switched from the console. Valid entries are:
REMOTE ratio comes from the remote ratio source
LOCAL ratio is from the local source (entered by operator at console)
OFF FCM does not use a ratio signal
