1 Part Names and Functions

This chapter explains the part names and functions on the face panel. The face panel has the PV and SV displays, the status indicating lamp, and the setting keys, etc. Those functions are explained below. Please read and understand them before using the PXR. For details about the setting of parameters, see Chapter 2.

qLamp for control output 1

Lights up while control output 1 stays ON.

wLamp for control output 2

Lights up while control output 2 stays ON.

eAlarm lamp

Lights up on detecting an alarm. The alarm output is turned ON at the same time.

If the optional heater break alarm is provided, the AL3 lamp lights up on detecting a heater break.

rPV (Measured value) display

Displays the PV. When setting a parameter, its name appears.

tSV (Setting value) display

Displays the SV. When setting a parameter, its value appears.

y SEL key

Used to select a parameter block and a parameter, and register a set value.

u keys

Used to change the SV, call parameters, and change parameter values.

iSV lamp

Lights up while the SV is displayed in the SV display. When parameters and data are displayed, the SV lamp goes out.

oAuto-tuning/self-tuning/manual mode lamp

Flashes under an auto-tuning or self-tuning operation. The lamp is kept on in manual mode.

2 Operations

This chapter explains how to set the SV (Setting value) and the parameters for the PXR.

2-1 Parameter list

Parameters for the PXR are classified into operation parameters, and the first block, the second block and the third block parameters according to the frequency of use. The second and the third block parameters are used at initialization or when they are absolutely necessary.

Manual mode setting (Settings: oFF/on)

[Description]

•This parameter switches the control mode between Auto and Manual.

•During Manual operation, the decimal point is kept on at the far right in the SV display section.

•During Manual operation, auto tuning or self tuning is not done. If the mode is switched to Manual while auto or self tuning is being done, the tuning is forcibly terminated. The PID parameter remains the same in such cases.

•Manual operation output is not limited by MV limit.

•Manual operation can be carried out during standby operation.

•The operation output set value during Auto/Manual operation mode and manual mode is stored in non-volatile memory. It is kept stored even if a power interruption occurs. When the power is turned on again, the state before the power interruption is resumed.

•The following table lists the operation output at the time of switching between Auto and Manual..

Standby setting (Settings: oFF/on)

[Description]

•This parameter switches the control between RUN and Standby.

•During standby, the control output and the alarm output stay OFF, like the standby for ramp-soak operation.

•While the alarm with a hold is selected, the hold function takes effect after changing the Standby setting from ON to OFF.

• is displayed during the standby for ramp-soak operations or the controller changes to the standby state in case of the occurrence of errors.

•The other operations are the same as those of the rampsoak standby.

•The setting of ON/OFF for standby is saved after poweroff.

•When the standby is set to ON during the auto-tuning, self-tuning, and ramp-soak operations, those operations will stop. (The PID constant will not be renewed.) Even through it is set to OFF later, the auto-tuning, self-tuning, and ramp-soak operations will not be re-started.

•During standby, the ON-delay timer is reset. When returning to RUN from the standby state, the timer will start from the beginning.

unchanged.

•Once the parameters of, , and are set automatically by the auto-tuning, those parameters are stored in the

controller even after it is powered off. Therefore, it is not necessary to execute the auto-tuning again.

•By setting to “1” or “2” , the auto-tuning operation starts, and at the end of the tuning, will be displayed automatically to .

•After the auto-tuning operation, the controller starts to operate at the automatically set values of, , and .

•A decimal point at the right end of the SV display flashes during auto-tuning.

•There are two codes for AT: Setting code [1]: SV standard type

Performs the auto-tuning based on the SV. Setting code [2]: Low PV type

Performs the auto-tuning based on the

SV-10%FS.

[Note]

Since ON/OFF control is performed during auto-tun- ing, overshoot against the SV may occur. To reduce the overshoot, execute the auto-tuning operation with the setting code [2] (Low PV) selected.

•The auto-tuning can be executed both just after power-on and in a control or stable status.
