[Burnout/Tuning] Tab (When PV/SP Computation Is OFF )
• Input Process
Burnout
Sets the burnout action for the PV inputs of each loop. You can select [OFF], [UP], or
[DOWN]. [No.2] is valid only when the control mode is set to [PVSwitching]; [Remote]
is valid only when the PV input is set to remote input. This setting is invalid for PV
inputs other than thermocouples and standard signals.
When PV/SP computation is ON, it is set according to “Control Input Channel” on page
7-12.
RJC (Type, Volt (uV))
This is the reference junction compensation setting for thermocouple inputs. The setting
is entered on the PV inputs of each loop. [No.2] is valid only when the control mode is
set to [PVSwitching]; [Remote] is valid only when the PV input is set to remote input.
This setting is invalid on the CX main unit for PV input other than thermocouples.
You can select [Internal] or [External] for Type.
If you select [External], set a voltage in the range from -20000 uV to 20000 uV.
When PV/SP computation is ON, it is set according to “Control Input Channels” on
page 7-12.
• Tuning Setting
Tuning item ON/OFF
Select [On] for the parameters that you want to display in the tuning window, and [Off]
for other parameters.
ID
Select the ID of the item from the following:
SP (target set point), A1 (alarm 1 setting), A2 (alarm 2 setting), A3 (alarm 3 setting), A4 ,
P (proportional range), I (integration time), D (differentiation time), OH (upper output limit),
OL (lower output limit), MR (manual reset), H (hysteresis), DR (control action direction), PO
(preset output), BS1 (measured value 1 input bias), FL1 (measured value 1 input filter), BS2
(measured value 2 input bias), FL2 (measured value 2 input filter), RT (ratio setting), RBS
(remote input bias), RFL (remote input filter), or W01–W36 (control computation constant).
BS1, FL1, BS2, FL2, and RFL cannot be selected when PV/SP computation is ON.
BS1, FL1, BS2, FL2, RT, RBS, RFL, and W01–W36 apply to style number S3 or later.
Name
Specify the name of the item using up to 6 alphanumeric characters.
