(5) Loop break alarm function

The loop break alarm function is used to detect a load (heater) break, a failure occurring in any

external operating device (magnet relay, etc.) or a failure occurring in the control system (control

loop) caused by an input (sensor) break. (Refer to P. 124.)

The loop break alarm can be output as summary output (OR output) from the digital output

block in the H-PCP-A/B module. For details, refer to 3.3 H-PCP Module (P. 36).

The loop break alarm can be output independently for each channel by connecting the

H-DO-A/B/D module. For details, refer to 3.9 H-DO Module (P. 70).
