Errors that can be detected by the ERR terminal
The following shows the errors that can be detected by the ERR terminal of the power
supply module in a singular power supply system/redundant power supply system.
<Singular power supply system> ................ One Q series power supply module is
used.
* : Except the Q00JCPU (without ERR terminal).
<Singular power supply system> ................ One slim type power supply module is
used.
* : Except the Q00JCPU (without ERR terminal).
<Redundant power supply system> ................. Two redundane power supply modules
are used.
* : Except the Q00JCPU (without ERR terminal).
