MVK-MP Specific
Sensor Short Circuit Short-circuit or overload at Pin 1 of the M12 socket causes the self-
setting fuse to be tripped. Every M12 socket is separately protected. A
red LED indicates the error at the respective M12 socket. This error is
reported via the DP diagnosis and possibly in the user data to the DP
master. After the error has been corrected, the sensor supply is
automatically restarted.
Actuator disable Short circuit or overload at an output causes the output to be disabled.
This error is reported via the DP diagnosis and possibly in the user
data to the DP master. A red LED indicates the error at the respective
M12 socket. The output is not automatically re-enabled. The output
must be disabled via the control after the error cause has been
removed. This deletes the short circuit memory.
Actuator warning When an output is disabled, the presence of 24V at the associated Pin
of the M12 socket is detected. This suggests a +24 "short-circuit". A
red LED indicates the error at the respective M12 socket. This error is
reported via the DP diagnosis and possibly in the user data to the DP
master. This error does not affect output control. It is not possible to
detect an actuator warning when the output is enabled.
Undervoltage Sensor supply and actuator voltages are registered separately. If
power drops below 18 V DC, this error is reported to the DP master
via the DP diagnosis. If the sensor supply voltage is low, the "U
S
Error"
LED lights up red. If the actuator supply voltage is low, the "U
A
Error"
LED lights up red.
External Error This diagnosis can only be generated by an input parameterized as a
diagnostic input. External error is reported when 0 V is present at this
input. Sensors and actuators meeting the DESINA specification are
supported in this manner. Alternatively, the line can be monitored for
breakage by using a diagnosis adapter.
Peripheral error A summary of individual errors that may occur at the M12 sockets.
This includes diagnostic reports, external errors, sensor short-circuit,
actuator shutdown, and actuator warning.
Virtual modules A configuration concept that describes a compact device as modular
system. This allows free assignment of individual data groups in the
process map.
Line break In the ranges of 4 to 20 mA and 2 to 10 V, falling below 4 mA and/or 2
V is considered an open circuit.
Over voltage If the measuring range is exceeded, diagnosis is generated.
