Note 2

Control output 2 (the codes “ A, C, and E ” in the 7th digit) cannot be specified.

Note 3

Control output 2, communication digital input (2 points), alarm (2 points), and 24V power supply (the codes “ A, C and E ” in the 7th digit, “ F and G ” in the 9th digit, and “ A, B, and C ” in the 10th digit) cannot be specified.

The default settings of input signals, measured ranges, and setting values are shown below.

Thermocouple specified : Thermocouple K, Measured range: 0 to 400°C,

Resistance bulb specified : Pt, Measured range: 0 to 150°C, Setting value:

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 under three blocks according to the frequency of use. The parameters of the second and third blocks are used at initialization or when they are of absolute necessity. Some parameters may not be displayed at the time of delivery depending on the type of the instrument.

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. Retransmission output is kept operated. (However, if the type of retransmission output is set to the MV, it becomes 4mA or lower.)

• 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 po wer off.

•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.

•The SV lamp flickers only when standby state.

• 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-tuning, 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.
