Input signal code (Setting range: 0 to 16)
[Description]
• This parameter is used for selecting input signals. Input
signal varies depending on the sensors (2 types below).
Set a code that corresponds to the sensor you use.
Type I
: Thermocouples (9 kinds of signals)
Resistance bulbs (1 kind of signal)
Type II
: Voltage, current
• Input signals can be selected within the same type. It is
impossible to select input signals of a different type.
• For type II, to change from the voltage input to the cur-
rent input, connect the supplied resistance of 250
Ω
be-
tween terminals
!7
and
!8
(in the case of PXR4), and
between terminals
#5
and
#6
(in the case of PXR5/9), in
addition to changing the code.
When changing from the current input to the voltage in-
put, remove the resistance of 250
Ω
as well as changing
the code.
[Note]
After changing the codes, power off the PXR, and then
power it on again.
