You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is greater than or equal to 21 mA or less than or equal to 3.6 mA for more than four seconds. The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal outside the normal 4-20 mA range.
For the standard 4 - 20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is above 21 mA or below 3.6 mA for more than four seconds. The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal outside the 3.6 to 21 mA NAMUR limits.
For the standard 0 - 20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT, the status of the input is set to Bad if the signal level is above 21 mA for more than four seconds. The Bad status is cleared when the signal returns below this limit. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal above the 21 mA NAMUR limit.
For the intrinsically safe 4-20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is above 21 mA or below 3.6 mA. The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal outside the 3.6 to 21 mA NAMUR limits.
For the intrinsically safe 0-20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is above 21 mA . The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal above the 21 mA NAMUR limits.
LS CHARM I/O
For the LS 4-20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is above 21 mA or below 3.6 mA. The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal outside the 3.6 to 21 mA NAMUR limits.
For the LS 0-20 mA CHARM: You can enable NAMUR limit detection for the analog input value by configuring the I/O channel properties NAMUR_ENA parameter. When this feature is enabled (TRUE) and the IO_IN type is FIELD_VAL_PCT or HART_FIELD_VAL, the status of the input is set to Bad if the signal level is above 21 mA . The Bad status is cleared when the signal returns within these limits. You can use this feature when the transmitter is designed to flag a device failure by setting its current signal above the 21 mA NAMUR limits.
