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.
