CT measurement wait time
If "CT operation" is set to "1: Detection of heater burnout for terminal OUT," the
time from the change in the output ON/OFF status to the start of the current
value measurement can be set. After the ON/OFF of the monitored OUT terminal
changes, measurement of the current value is started once the measurement wait
time has elapsed.

Heater burnout detection current value
If the current value when output is ON is the set value or less, heater burnout is
detected.
If the setting is 0.0, the detection function is stopped.
Note
• As a general guide, the setting should be midway between the normal current
value and the burnout current value. Also, set so that the difference between
the normal current value and burnout current value is 5 % FS or more of the
measurement current range.
CT input display range and current measurement range (p.4-82)
Normal current + Burnout current
Set value =
2
• If the CT operation is set to "0: Continuous current measurement," current value
low limit errors can be detected using the heater burnout detection current value
setting as the current low limit.

Overcurrent detection current value
If the measured current when output is ON exceeds the setting, overcurrent is
detected.
If the setting is 0.0, the detection function is stopped.
Note
• As a general guide, the setting should be midway between the normal current
value and the overcurrent value. Also, set so that the difference between
the normal current value and overcurrent value is 5 % FS or more of the
measurement current range.
CT input display range and current measurement range (p.4-82)
Overcurrent + Normal current
Set value =
2
• If the CT operation is set to "0: Continuous current measurement," current high
limit errors can be detected using this setting.
