(15)Redundant power supply module information
*1: The "power supply 1" indicates the redundant power supply module (Q64RP) mounted on the POWER 1 slot of the redundant base unit (Q38RB/68RB).
The "power supply 2" indicates the redundant power supply module (Q64RP) mounted on the POWER 2 slot of the redundant base unit (Q38RB/68RB).

• Turns ON when one or more redundant power
supply modules with input power OFF are detected.
• SM turns on if single bit of SD1780 is on.
• SM turns off if all bits of SD1780 are off.

• Turns ON when a momentary power failure of the
input power supply to the power supply 1 or 2 is
detected one or more times. After turning ON,
remains ON if the power supply recovers from the
momentary power failure.
• Turns OFF the flag (SM1782, SM1783) of the power
supply 1/2 when the CPU module starts.
• This relay turns OFF when the input power to either
redundant power supply module switches OFF.
• This relay turns OFF when the main base unit is not
the redundant main base unit (Q38RB).
