7.3.2.3.3 Heat Trace Monitoring Parameter List

Parameter name

default value
Description
1
Diag Error
0x0000
The results detected by ILBD or heat trace monitoring are stored in this
parameter. Also the condition abnormality in the diagnostic process is
stored as an error.
2
Diag Option
0x08f8
Use this parameter to select the error messages and status to reflect in the
LCD and output signals. The errors assigned to each bit correspond to the
bits of Diag Error.
This parameter is selectable only when Diag Mode is set to Stop.
3
Diag Out Option
Off
Error status can be output with the 4 to 20 mA analog signal. The available
three output modes are Off, Burnout, and Fall back.
4
Diag Fixed Out Val
21.6 mA
A parameter for the fall back function in Diag Out option.
This specifies the output value of the 4 to 20mA analog signal when alarms
occur.
The value can be entered in the range of 3.8 to 21.6 mA.
5
Temp 1
Measured Module 1 side capsule temperature value
6
Amp temp
Measured Module 1 side amplifier temperature value
7
Flg temp
(*1)
Calculated flange temperature value
8
Flg temp coef
0
Coefficient to calculate flange temperature (Cf: Rt1/Rt2)
Rt1: Thermal resistance between the flange and capsule.
Rt2 : Thermal resistance between the capsule and amplifier.
9
Flg temp Hi alart val 120 degC
Upper limit of flange temperature
10
Flg temp Lo alart val
–40 degC
Lower limit of flange temperature
(*1): By factory default, Flg Temp Coef is set to 0, so the flange temperature indicates the same temperature as the capsule temperature.
