PD+MR
PD WITH MANUAL RESET is used whenever
integral action is not wanted for automatic control.
The equation is computed with no integral
contribution. The MANUAL RESET, which is
operator adjustable, is then added to the present
output to form the controller output.
Switching between manual and automatic mode will
be bumpless.
If you select PD with Manual Reset you can also
configure the following variations
• PD (Two Mode) control,
• P (Single Mode) control.
Set Rate (D) to 0.
Other prompts affected: "MANRESET3"
M/A STN
MANUAL/AUTO STATION—Provides an operator display
for the TDC PID loop PV, SP, OP and MODE. The UDC
loop has only Manual control at the UDC6300. Auto mode
for the loop is maintained in the TDC.
If you select Auto mode at the UDC, the MAN indicator will
blink, indicating AUTO is not available.
When the TDC provides an output override value, MAN
indicator will turn OFF.
AUTO indicator is never displayed. Output override does
not necessarily mean that the loop is in AUTO.
Other configuration settings required:
Setup CONTROL2 prompt PV2 SRC = NONE.
Setup CONTROL2 prompts SPHILIM, SPLOLIM = PV and
SP range (for bargraph).
Refer to Manual/Auto Station Addendum 51-52-99-08 for
implementation details.
