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.

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.
Parameters of the first block
This chapter explains how to set the SV (Setting value) and the parameters for the PXR.
Used for setting the constants for , ,
and by auto-tuning.

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.
[Setting example] Starting the control
• The other operations are the same as those of the ramp-
soak standby.
• The setting of ON/OFF for standby is saved after power-
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.

soak operation can be programmed.
•The first ramp starts at the PV (Measured value) that is
the one just before running the program.

Auto-tuning function (Settings: 0/1/2)

the auto-tuning cancel with each parameter of , , and
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
