Note 1) The self-diagnosis output contact is so configured that the auxiliary relay can be energized ("break contact" opened) when normal result of self-diagnosis is received.
This type of contact will allow the relay to continue automatic self-check even after the built-in power fuse burns. Therefore, the "break contact" is closed when the power
is applied and will be opened after about 50ms. If the auxiliary power supply of the relay and the self-diagnosis output contact shares a same power source, the "break
contact" will be closed temporarily after the auxiliary power supply is turned on. In the case where the phenomenon stated in the above would conflict with your
system requirement, it is recommended that the self-diagnosis output contact should be connected via the time-delayed timer as shown in the left of the figure.
Note 2) Regarding to the type CPS1 AC/DC converter or commercially available uninterruptible power supply (UPS), refer to the note *21 in the section 2.1 General information.
