(2) Redundant power supply system
* 2: The operation of the ERR terminal is as fllows.
<When the redundant power supply module is mounted on the redundant power main base unit>
The terminal turns OFF (opens) when the AC power is not input, a CPU module stop error
(including a reset) occurs, the redundant power supply module fails, or the fuse of the redundant
power supply module is blown.
<When the redundant power supply module is mounted on the redundant power extension base
unit>
The terminal turns OFF (opens) when the redundant power supply module fails.
* 3 When input power is supplied to the redundant power supply module mounted on the redundant
power main base unit and the redundant power supply module mounted on the redundant power
extension base unit simultaneously, the ON (short) timing of the ERR
terminal on the redundant
power main base unit is later than that of the ERR
terminal on the redundant power extension
base unit by the initial processing time of the CPU module.
