2.2.10 Bias (Manual Reset)
This bias to the output power is expressed as a percentage of output power. This
parameter is not applicable if Proportional Band 1 = 0.
2.2.11 ON/OFF Differential
This is a switching differential used when one or both outputs have been set to
ON/OFF control (i.e. Proportional Band 1 or Proportional Band 2 or both = 0).
2.2.12 Setpoint High Limit
This is the maximum limit for setpoint adjustment. It should be set to a value which
prevents the setpoint being given a value which will cause damage to the
process being controlled.
2.2.13 Setpoint Low Limit
This is the minimum limit for setpoint adjustment. It should be set to a value which
prevents the setpoint being given a value which will cause damage to the
process being controlled.
2.2.14 Recorder Output Scale Maximum
This parameter defines the value of process variable or setpoint (whichever is
applicable) at which the Recorder Output reaches its maximum value; for
example, for a 0 - 5V Recorder Output, this value corresponds to 5V. The decimal
point position for the Recorder Output is always the same as that for the process
variable input range. This parameter is not applicable if the Recorder Output
option is not fitted.
NOTE: If this parameter is set to a value less than that for the Recorder
Output Scale Minimum (see Subsection 2.2.15), the relationship between
the process variable/setpoint value and the Recorder Output is reversed.
2.2.15 Recorder Output Scale Minimum
This parameter defines the value of the process variable or setpoint (whichever is
applicable) at which the Recorder Output reaches its minimum value; for
example, for a 0 - 5V Recorder Output, this value corresponds to 0V. The decimal
point position for the Recorder Output is always the same as that for the process
variable input range. This parameter is not applicable if the Recorder Output
option is not fitted.
NOTE: If this parameter is set to a value greater than that for the Recorder
Output Scale Maximum (see Subsection 2.2.14), the relationship between
the process variable value and the Recorder Output is reversed.
