Failure alarm down-scale: output status at CPU failure and
hardware error is –5%, 3.2 mA or less.
Failure alarm up-scale: output status at CPU failure and
hardware error is 110%, 21.6 mA or more.

Applicable for Output signal code D and E. The hardware error indicates faulty amplifier or
capsule. When combining with Optional code F1, output status for down-scale is –2.5%,
3.6 mA DC or less.
