*1 At the initial processing, the LEDs (PW LED, RUN LED, MODE LED, D LINK LED, SAFETY LED, ERR. LED, and I/O LED) turn on for a
moment to check if the LEDs turn on.
*2 When the module power supply voltage does not reach the allowable voltage range at the initial processing, the initial processing is
suspended and the module enters the standby state until the module power supply voltage reaches the allowable voltage range.
If this state continues for two minutes or longer, a hardware failure occurs and the module stops the operation. To recover the module,
power off and on the module power supply.
When the module power supply voltage reaches the allowable voltage range within two minutes after this state occurs, the initial
processing is continued.
*3 Either of On or Off.
*4 Any of On, Flashing, or Off.
*5 When the module is failed, the LED may not turn on.
*6 Either of On or Flashing.
*7 Either of Flashing or Off.
