l
Process parameter
Set process parameter to output according to sensors. If the setting is not configured
appropriately, a setting error occurs.
Selecting appropriate process parameter according to sensors to use.

*1:
Latest revision does not support script. Do not select script.
*2:
When you connect multiple sensors, you will gain the arithmetic from Sensor 1-1 and Sensor 2-1. In order to gain this value, set
same type of sensors to Sensor 1-1 and Sensor 2-1, otherwise a setting error will be detected. Note that latest revision does not
support the arithmetic out of multi sensors.
l
output setup
Select one of the output methods, Linear or Table.
Linear:
Set 0% value and 100% values.
Table:
This allows the configuration of an output curve by 21 points.
l
Sub linear 0%, Sublinear 100%
Set 0% and 100% value at Contact input change range.
l
Burn
When a failure happens, burn is output. Select one mA from “Off”, “Law” or “High” to output the
Error settings for setting failures.
Off:
Output by the measured value.
Low:
Output is fixed to 2.2 mA
High:
Output is fixed to 22.0 mA.
Burn happens only when failure is detected on the sensors you set on Process parameter slot.
Sensors you did not set on Process parameter slot do not output burn even when their failure is
detected.
Whenever the converter’s failure is detected, it outputs burn value.
If a communication error inside of the converter is detected, the converter seeks the error
location: first or second sensor module. Only when the analog sensor module you set detects an
error, burn is output.
l
Damping time
This is the time taken for a response to a step input change to reach 90% of the final value
(attenuation time). Set this time in sec.
