Output Tracking Enable
With Output Tracking enabled, if the slave controller is changed to local set
point, the Master output tracks the local set point value of the slave.
Remote (Cascade) Set Point Tracking Enable
If Remote (Cascade) Set Point Tracking is enabled and the controller is in
Remote (Cascade) mode the local set point tracks the remote set point. When
the controller is in Remote (Cascade) Set Point Tracking mode the local set
point limits can be exceeded. If the local set point is outside of its limits when
selected, the set point can only be adjusted towards its limits. Once within the
limits they apply as normal. With remote set point tracking enabled; if the
controller is put into manual mode, the set point reverts from remote to local.
Select
ON
to enable or
OFF
to disable.
Remote (Cascade) Set Point High Limit
The high limit is the maximum value to which the remote (cascade) set point can
be adjusted.
Select the value required. The decimal point position is set automatically.
Remote (Cascade) Set Point Low Limit
The low limit is the minimum value to which the remote (cascade) set point can
be adjusted.
Select the value required. The decimal point position is set automatically.
Remote (Cascade) Set Point Ratio
The ratio is a scaling factor, i.e. multiplies the remote (or cascade) set point input by the ratio
value set – see Fig. 4.2. Set the required ratio, between 0.010 and 9.999 in 0.001 increments.
Remote (Cascade) Set Point Bias
The bias is an offset which is added to the remote (cascade) set point value – see Fig. 4.2.
Set the required bias, in engineering units.
Set Point Type Selection
The balance (
bALNCE
) display shows the difference between the local and second (remote, dual
or cascade) values, i.e.
Balance
=
Second set point – Local set point
If the difference is too great, press the
or
switch to exit this frame, select the local set
point frame (
LOCAL
) in this page or the
Operating Page
and adjust to an acceptable balance.
