8.2 Error in auxiliary/actuator power
supply
Technical manual LioN-P PROFINET IO-Link Master
Release 2.0 04/2017
8.2
Error in auxiliary/actuator power supply
The voltage value for the incoming auxiliary/actuator power supply is also
monitored globally. If U
Aux
diagnostic messaging is enabled, an error
message is generated if the voltage drops below approx. 18,6 V or exceeds
approx. 30 V.
The U
Aux
indicator shows red.
If output channels are enabled, additional error messages caused by the
voltage failure are generated on the I/O ports.
U
Aux
diagnostic messaging is disabled by default and must be enabled via
parameterization.
The following group diagnostic message is generated:
8.3
Overload/short-circuit of the I/O port sensor
supply outputs
In case of an overload or a short circuit between pin 1 and pin 3 on the ports
(X1 - X8), the following channel-specific diagnostic messages are generated:
Channel number of diagnosis
0x8000 (diagnosis not channel-specific)
Channel related diagnosis code
0x0103
Channel related diagnosis code
message
Voltage fault of auxiliary power supply (U
Aux
), detected by
IO-Link master.
Channel number of diagnosis
0x01 - 0x08
Channel related diagnosis code
0x01
Channel related diagnosis code
message
Short circuit
Extended description
