[Input abnormality indication]
Output status
selection when
input abnormal
[Output status selection when input abnormal] is available only for DC input and DC current output.
For other inputs and outputs except for DC input and DC current output, the output status will be
the same as when OFF is selected during [Output status selection when input abnormal].
(*): Outputs a value between OFF (4mA) and ON (20mA) or between OUT low limit value and
OUT high limit value, depending on deviation.

11.2 Optional specifications
Heater burnout alarm (option)
Watches the heater current with CT (Current transformer) and detects the burnout.
This alarm is also activated when indication is overscale and underscale.
(To detect Heater burnout, a CT for 50A can also be used for 5A, 10A and 20A ratings, however, this
is not suitable for small ampere ratings due to a low degree of accuracy. For a 20A rating or less, use
a CT designated for 20A.)
