2.2.30 Scale Range Maximum
This parameter, applicable only if a linear input is fitted, defines the scaled input
value when the process variable input hardware is at its maximum value. This
parameter can be set to a value less than (but not equal to) Scale Range
Minimum, in which case the sense of the input is reversed. Decimal point position
is defined by the Scale Range Decimal Point parameter (see Subsection 2.2.29).
2.2.31 Scale Range Minimum
This parameter, applicable only if a linear input is fitted, defines the scaled input
value when the process variable input hardware is at its minimum value. This
parameter can be set to a value greater than (but not equal to) Scale Range
Maximum, in which case the sense of the input is reversed. Decimal point position
is defined by the Scale Range Decimal Point parameter (see Subsection 2.2.29).
2.2.32 Auto Pre-Tune Enable/Disable
This parameter determines whether or not the Controller’s Pre-Tune facility is
activated automatically on power-up or not.
2.2.33 Manual Control Enable/Disable
This parameter determines whether operator selection of manual control is
enabled or disabled.
2.2.34 Setpoint Ramp Enable/Disable
This parameter enables/disables use of the setpoint ramping feature at user level.
2.2.35 Setpoint Strategy
This parameter enables the user to select the required Operator Mode setpoint
display strategy - see Subsections 1.2.1 (Single Setpoint operation) and 1.2.2 (Dual
Setpoint operation).
2.2.36 Communications Enable/Disable
This parameter enables/disables Write operations (i.e. the changing of parameter
values/settings) via the RS485 communications link, if the Communications Option
PCB is fitted. Parameters can be interrogated via the link, regardless of the setting
of this parameter.
2.2.37 Lock Value
This parameter defines the four-digit code required to enter Set Up Mode.
