... after a comparison
interval, a position

In the last comparison

much that a deviating
position average was
calculated.
Table 4-2 Events that can activate the fault message output
Explanations for the “Error codes” column:
1 Control deviation monitoring
In automatic mode, the deviation between the setpoint and actual value
is monitored continuously. According to the setting of parameter
48. TIM, the monitoring time for setting the fault messages, and
49. LIM, the response threshold of the fault message, the fault
message is activated if the control deviation remains. As soon as the
control deviation falls below the response threshold again, the fault
message is cancelled.
2 Automatic mode monitoring
If parameter “47. FCT”, the fault message output function, is set
accordingly, a fault message is generated if the device is not in
automatic mode. In this way, e.g. the control system can be warned if
the device was switched to manual mode or configuration on location.
3 Binary input BE1 or BE2 active
If parameter “47. FCT”, the fault message output function, and
parameter “42.BIN1”, the binary input 1 function, are set accordingly,
a fault message is generated when the binary input is activated. This
can be e.g. a stuffing box monitoring switch, a temperature switch or a
limit switch (e.g. for pressure).
Binary input 2 (for the alarm unit option) can be configured in the same
way.
