RAS

RAS stands for Reliability, Availability, and Serviceability. This function improves overall usability of automated equipment.

Module power supply voltage drop detection

Detects a voltage drop of the module power supply.
This function makes troubleshooting easy when the voltage of power supplied to the NZ2GN-GFB drops or when poor
connection in the wiring occurs.
Operation
The module power supply voltage drop detection function starts from the time 500ms passes after the NZ2GN-GFB is
powered on.
When the module power supply voltage drops below 20.4VDC, an error (error code: 0240H) occurs.
Setting method
This function is always enabled. There is no need to set it.
Precautions
The voltage to be detected varies depending on the environment.
When an error is detected, since the power supply environment is out of specification range, the operation is not guaranteed.
A power supply voltage drop is not detected in the event of a sudden power failure or when power-off operation is performed.
