process being controlled. The Setpoint Low Limit may be adjusted between the
Input Range Minimum and the current setpoint value. The default value is Input
Range Minimum.
3.2.14 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. It may be
adjusted within the range –1999 to 9999. The decimal point position for the
Recorder Output is always the same as that for the process variable input range.
The default value is Input Range Maximum. 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 3.2.15), the relationship between
the process variable/setpoint value and the Recorder Output is reversed.
3.2.15 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. It may be
adjusted within the range –1999 to 9999. The decimal point position for the
Recorder Output is always the same as that for the process variable input range.
The default value is Input Range Minimum. 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 3.2.14), the relationship between
the process variable value and the Recorder Output is reversed.
3.2.16 Output 1 Power Limit
This parameter is used to limit the power level of Output 1 and may be used to
protect the process being controlled. If no protection is required, this parameter
may be set to 100% (the default value). It may be adjusted between 0% and
100%. This parameter is not applicable if Proportional Band 1 is set to 0.
If Soft Start is used, this power limit is applicable ony during Soft Start. When Soft
Start is completed, Output 1 power can go to 100%.
3.2.17 Output 1 Cycle Time
The cycle time value required is dependent upon the process being controlled
and the type of output being used for Output 1. For a Relay Output, the cycle
time should be as large as possible (whilst remaining compatible with the process
