Module Power Supply Voltage Drop Detection
Function
This function detects a voltage drop in the module power supply, and detects a module power supply failure or wiring error
from the upper system.
For the specifications of the module power supply to NZ2AW1GNAL, refer to the following.

How to check the module power supply voltage drop status
If the module power supply voltage drops, the NZ2AW1GNAL will be in the following status.
• When a voltage drop is detected, the ERR. LED turns on.
• Module power supply voltage drop error (RX3) turns on.
• Module power supply voltage drop error (error code: 2500H) is stored in the Latest error code storage area (RWr0), and
"0FFFH" is stored in the Latest error ID storage area (RWr1).
• The AnyWireASLINK transmission stops.
*1 If multiple errors occur simultaneously, the latest error is displayed.
How to recover from the module power supply voltage drop state
How to recover from the module power supply voltage drop state is as follows.
1.
Check the voltage of the module power supply, and replace the power supply or check the wiring as necessary.
2.
After clearing the module power supply voltage drop state, power off and on the module power supply or perform a
remote reset.
The following status is resulted.
• Module power supply voltage drop error (RX3) turns off.
• The ERR. LED turns off.
• The data in Latest error code storage area (RWr0) and Latest error ID storage area (RWr1) are cleared.
