…Control / …Loop 1 (2) Output
Rate
The maximum rate of change of the control output (% / s).
Disable
S
ource
The source required to disable slew rate control of the
output. This source is level-triggered.
Tracking
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.
S
ource
S
ignal
S
ource
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 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 E OP
When enable source is active, Control output = tracking change in
PID
output,
when in
Auto
control mode.
Enable
S
ource
Sets the digital signal to enable output tracking.
Note
. Applicable only if
Mode
is

or
When E 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.
