Replacement of the redundant power supply module
This section describes the procedure for replacing the redundant power supply module in the redundant power supply system
configuration.
■Preventing detection of error in redundant power supply module
1.
Set "Not Detected" in the following.
[CPU Parameter]  [RAS Setting]  [Error Detections Setting]  [Redundant Power Supply System Error]
2.
Replace the redundant power supply module.
 MELSEC iQ-R Module Configuration Manual
Since an error is not detected in the redundant power supply system when the redundant power supply module is replaced,
the error in the redundant power supply system do not need to be cleared.
■Detecting error in redundant power supply module
1.
Set "Detect" in the following.
[CPU Parameter]  [RAS Setting]  [Error Detections Setting]  [Redundant Power Supply System Error]
2.
Replace the redundant power supply module.
 MELSEC iQ-R Module Configuration Manual
3.
Clear the error in the redundant power supply system by turning on either 'Error clear' (SM50) of the remote head module
or 'Error clear' (SB000F) of the master station.
■Detecting error in redundant power supply module and preventing detection of error in
normal redundant power supply module
1.
Set "Detect" in the following.
[CPU Parameter]  [RAS Setting]  [Error Detections Setting]  [Redundant Power Supply System Error]
2.
Turn on 'Error clear' (SB000F) of the master station.
When 'Error clear' (SB000F) of the master station is on, the remote head module does not detect an error in the redundant
power supply module.
3.
Replace the redundant power supply module.

4.
Turn off 'Error clear' (SB000F) of the master station.
