Power supply diagnostic through LED
The P2M Node 24DO monitors the auxiliary power supply voltage and manages two levels of diagnostics;
warning and error range. The normal range can be modified through Manufacturing Specific Objects.

LED function details:
•
‘’Auxiliary power’’ error is active from 9 to 18 Vdc or above 28,5 Vdc

Auxiliary power supply range adjustment
Normal auxiliary power supply voltage range is set by default as 20,0V < Aux power supply < 26,4V
The low and high limits of the Voltage Warning levels are adjustable via the Manufacturing Specific Object
“ AUX Voltage Warning Low Limit” and “AUX Voltage Warning High Limit”
Values shown in mV.
•
Diag 1 : Auxiliary Voltage in Warning range. The limits of the Warning range can be adjusted via the Objects “ AUX
Voltage Warning Low Limit” and AUX Voltage Warning High Limit”
•
Diag 2 : Auxiliary Voltage failure. If AUX Voltage < 18 Vdc or > 28,5 Vdc. Module goes into Failsafe Status.
Acknowledge is required to restart the module. Values cannot be adjusted.
