Input error determination point (low) (1. PUn, 2. PUn)
Use to set Input error determination point (low). Input error determination function is activated when a measured
value reaches the limit, and control output value selected by Action at input error will be output.
Data range:
Input scale low
(5 % of input span) to Input scale high + (5 % of input span)
Factory set value:
Input 1_input error determination point (low) (1. PUn):
Pressure sensor input:
Input scale low
(5 % of input span)
Voltage (V)/Current (I) inputs:
5.0
Input 2_input error determination point (low) (1. PUn):
TC/RTD inputs:
Input scale low
(5 % of input span)
Voltage (V)/Current (I) inputs:
5.0
Related parameters:
Input error determination point (high) (P. 70), Action at input error (high) (P. 89),
Action at input error (low) (P. 89), Manipulated output value at input error (P. 90)
[Example]
When the input scale is 0.0 to 250.0:
Input span: 250.0, 5 % of input span: 12.5, Setting range:
12.5 to
262.5
Burnout direction (1. boS, 2. boS)
Use to select Burnout direction in input break. When input break is detected by the controller, the measured
value go either Upscale or Downscale according to the Burnout direction setting.
Data range:
Pressure sensor input [Input 1]:
0 (Upscale), 1 (Downscale)
TC input [Input 2]:
0 (Upscale), 1 (Downscale)
RTD input [Input 2]:
0 (Upscale)
Voltage (low) input [Input 1, Input 2]: 0 (Upscale), 1 (Downscale)
Voltage (high) input [Input 1, Input 2]: 1 (Downscale)
Current (I) input [Input 1, Input 2]:
1 (Downscale)
Factory set value:
Input 1_burnout direction (1. boS):
0 (Upscale)
Input 2_burnout direction (2. boS):
0 (Upscale)
For the following types of input, the action when an input break occurs is fixed, regardless of the
Burnout direction setting.
RTD input:
Upscale
Voltage (high) input: Downscale (Indicates value near 0 V.)
Current (I) input:
Downscale (Indicates value near 0 mA.)
