Chapter 7 Troubleshooting
This chapter describes how to check the causes of trouble and what remedial steps
should be taken if the DN611 goes wrong during its operation. Also refer to the
Sequence Controller User's Manual in dealing with trouble.
7.1 At Module Start

If the module is normal, the DN611 starts initializing the module when power is turned
on or when reset is requested, and then is set in standby mode.
Standby: MS, NS: OFF 7-Segment LED: Node address is shown lit.
