Continued from the previous page.
The heater break alarm function in this instrument cannot be used with continuous analog
output.
Break detection:
If the current transformer input measured value read from the CT is smaller than the preset heater
break alarm set value even with the control output produced, the heater break alarm is turned on.
Welding detection:
If the current transformer input measured value read from the CT is larger than the preset heater break
alarm set value even with the control output produced, the heater break alarm is turned on.
z Data of error code
The error code [Extension No. 32] bit pattern becomes as follows.
When temperature control channel related setting data are written into the remote device
station (temperature control modules) by the master station (PLC), make sure all the
temperature control channel related setting data are set within the setting range.
Any single data set outside the setting range may cause b0 (Set data range check error) to
become 1 (abnormal).
Even if the setting data belongs to the channel not used by the user, as long as the data exists
outside the setting range, b0 (Set data range check error) becomes 1 (abnormal).
“1: Backup data check error,” “2: RAM read/write error” or “4: Internal communication
error” may not be recognized by the H-LNK-A module if the H-PCP module cannot
recognize the H-LNK-A module.
If a hardware error (SR Mini HG error code) occurs, the remote input hardware error flag
[RXnF] is turned on.
