CS1W-PTS03 Isolated-type Resistance Thermometer Input Unit

Error Processing
Conversion Data Does Not Change.
Probable cause
The gain for span adjustment is
set to 0.
The minimum and maximum val-
ues for process value scaling are
either the same or are set
extremely low.
The sensor type, input range, or
process value scaling is not set
correctly.
An input device is malfunctioning,
input wiring is faulty, or wiring is
disconnected.
Values are Not Converted as Intended.
Probable cause
The sensor type, input range, or
process value scaling is not set
correctly.
The zero/span adjustment data is
incorrect.
The resistance thermometer
input wiring is faulty.
Converted Values are Unstable.
Probable cause
Input signals are being affected
by external noise.
The process value scaling value
is greater than the Unit's resolu-
tion.
The input signal range setting is
too small.

Unit
Overview
Set the gain for span adjustment to a value other than 0.
Set the minimum and maximum values correctly.
Check and correct the settings.
Check whether the input voltage or current has changed. Check for faulty or discon-
nected wiring. Check whether a wiring disconnection has been detected in the I/O
Area.
Check and correct the settings.
Check and correct the zero/span adjustment settings.
Correct the input wiring.
Change the connection paths of the input signal lines. (Separate them from sources of
noise or use shielded cable.)
Increase the number of values for calculating the moving average in mean value pro-
cessing.
Reduce the process value scaling value.
Match the input signal range to the internal ranges.
The CS1W-PTS03 Isolated-type Resistance Thermometer Input Unit provides
four direct Ni thermometer inputs, and sends the data to the CPU Unit each
cycle. All inputs are isolated.
