4.2.3.3 Parameter Lists for Heat Trace Monitoring
# Parameter name Default value Explanation
1 Diag Error 0x0000 The results detected by ILBD or Heat trace monitoring are stored into this
parameter. Also the condition abnormality in the diagnostic process is
stored as an error.
2 Diag Option 0x08FC The masking in this parameter enable to display each error message and
the status to the output signal or LCD.
The error assigned to each bit is corresponding to that of Diag Error.
Writable only when Diag Mode is "Stop".
3 Diag Out Option O󰀨 The error status can be output by 4-20 mA analog signal.
There are following three output modes; O󰀨, Burnout, or Fall back.
4 Diag Fixed Out Val 21.6mA Parameter for "Fall back" function in the Diag Out option.
The output value in 4-20 mA analog signal is specied when an alarm is
generated.
The value must be entered within 3.6 to 21.6 mA.
5 Snsr temp (Cap temp
*2
) Measured capsule temperature value
6 Amp temp Measured Amplier temperature value
7 Flg temp (
*1
) Calculated ange temperature value
8 Flg Temp Coef 0 Coe󰀩cient to calculate ange temperature (Cf: Rt
1
/Rt
2
)
Rt
1
: Thermal resistance between the ange and capsule.
Rt
2
: Thermal resistance between the cupsule and amplier.
9 Flg Temp Hi Alart Val
(Flg Temp High Limit
*2
)
120 deg C Upper limit of Flgtemp
10 Flg Temp Lo Alart Val
(Flg Temp Low Limit
*2
)
-40 deg C Lower limit of Flgtemp
11 DO Select O󰀨 See subsection 3.3.13 Status Output
12 DO Signal type ON WHEN
AL DETECT
See subsection 3.3.13 Status Output
13 Digital Output O󰀨 See subsection 3.3.13 Status Output
*1: The FlgTempCoef is 0 at the shipment so that the Flgtemp outputs the same value as that of Snsr temp.
*2: EJX HART 5 DTM based on FDT1.2.
