6.2.3.17.1 Error code maintenance
Once the error code is set, it will not be cleared until the instrument is reset, or it is
manually cleared using one of the three following methods.
6.2.3.17.1.1 Enter “SERVICE”→”CLR ERROR”, the fault code will be cleared, but will reappear
if the issue persists.
6.2.3.17.1.2 Write the fault code clear code “60000” to Modbus address “1276”. the fault
code will be cleared, but will reappear if the issue persists.
6.2.3.17.1.3 Write the fault code shielding code (set the position to be shielded as 1) to
Modbus address “1276”. the fault code will be blocked until the shielding code is
removed.
6.2.3.18 Cutoff ratio of mass flow / volume flow
Once the measured mass (volume) flow rate is less than the low flow cutoff proportion,
the output will drive to Zero.
6.2.3.19 Internal calibration of 4mA & 20mA (AO1-AO2)
Analog output can be calibrated as follows:
6.2.3.19.1 Fixed instrument output 4mA, measured analog output value, denoted as x1.
6.2.3.19.2 Fixed instrument output 20mA, measured analog output value, denoted as x2.
6.2.3.19.3 X1 and X2 are written to the corresponding parameters.
6.2.3.20 Current output value-CH1/CH2
When read, this will contain the actual output current of corresponding current loop
channel. When written to, if the written value is between 4mA to 20mA, then the
corresponding current loop channel will output the written value; if the written value is 0,
then the corresponding current loop output will return to outputting the assigned process
variable.
