3.9.3 Functional description

(1) Alarm output function (only for H-DO-A, H-DO-B and H-DO-D types)

Alarm output function types

Any alarm selected from the following alarm output functions can be output for each channel.

Temperature alarm output (alarm 1 and alarm 2)

This alarm is output when the measured value (PV) of the H-TIO module is within the alarm setting

range.

The alarm 1 and alarm 2 are output for each channel.

Heater break alarm output

This alarm is output for each channel when the heater current detected by the current transformer is

within the heater break alarm setting range.

Burnout alarm output

This alarm is output for each channel when the input (sensor) breaks or the input value exceeds the

scaling range.

Loop break alarm output

This alarm is output for each channel when an error occurs in the control loop.

AI alarm output (AI alarm 1 and AI alarm 2)

This alarm is output when the measured value (PV) of the H-AI module is within the AI alarm setting

range. The AI alarm 1 and AI alarm 2 are output for each channel.
