…Control / …Loop 1 (2) Output
Rate The maximum rate of change of the control output (% / s).
Disable Source The source required to disable slew rate control of the
output. This source is level-triggered.
Trac king Enables the control output to be configured to follow a tracking signal when in Auto control
mode. When in Manual control mode the output can be adjusted by the user as normal. If
the slew rate function is enabled, switching from Manual to Auto is bumpless. If the value set
by the tracking signal is different to that set manually, the output ramps to its expected auto
value at the speed set in the slew rate.
If the Signal Source is set to None tracking is disabled and the normal PID output is provided
as the control output.
Source
Signal Source
Sets the source of the signal required to be tracked by the output in Auto control mode. If
set to None, output tracking is disabled.
Mode Selects the type of output tracking.
In Auto
Control output = tracking signal when in Auto control mode.
Auto + OP
Control output = tracking signal + change in PID output, when in Auto control mode.
When Enabled
When enable source is active, Control output = tracking signal when in Auto control mode.
When Enabled + OP
When enable source is active, Control output = tracking signal + change in PID output,
when in Auto control mode.
Enable Source Sets the digital signal to enable output tracking.
Note. Applicable only if Mode is When Enabled or When Enabled + OP.
Loop 1 (2) Split O/P* This facility enables the PID control output (see page 30) to be split into 2 separate outputs.
This enables heat / cool and other applications requiring dual outputs to be controlled. The
linear relationship between the input from the PID algorithm and the 2 outputs is configured
using the Min/Max Input/Output parameters (below).
When operating with Split O/P in Manual control mode, manual adjustment is made to the
input at the split output block (x axis). By default, the Operator page displays both output
values (OP1 and OP2).
*Applicable only if the output type selected is Split O/P – see page 34.
