12. Troubleshooting
This chapter describes Fault (errors) and alarms detected by the self-diagnostic function of the
converter. It also explains inspections and remedies when other problems occur.
12.1 Displays and Remedies When Fault Occur
12.1.1 Fault
A Fault occurs when an abnormality is detected in the detector or the converter, e.g., in the cell
(sensor), detector heater, or internal circuits of the the converter.
If a Fault occurs, the converter performs the following:
(1) Stops the supply of power to the heater in the detector to insure system safety.
(2) Fault indication is displayed by blinking the icon to notify of a Fault generation (Figure 12.1).
(3) When Fault is set to output in “Selection of contact output”, Fault is output to contact.
(refer to Section
“8.5 Output Contact Setup”.)
(4) The analog output becomes the status which is set in “Output hold setting”.
(refer to Section “8.2 Output Hold Setting”.)
When the display shown in Figure 12.1 (1) appears, pressing the Fault indication brings up a
description of the Fault (Figure 12.1 (2))
