The followi
ng settings are possible for each fault message:
 Fault status message delay: Elapsed time until a pending fault generates a fault
message.
 Fault acknowledgement
 Fault priority
 Limit value fault on: Limit value from which the fault message is generated.
 Limit value fault off: Limit value for the normal state.

Limit value fault on Depending on selected type. Type-dependent.
Limit value fault off Depending on selected type. Type-dependent.
 If the upper and lower limit of a measured value is to be monitored, the signal is
must be sent to 2 fault inputs.
Note


For monitoring, set the lower limit "Limit value fault on" to lower than "Limit value
fault off". This generates a fault message when the measured value is lower
than the "Limit value fault on".
 The difference between "Limit value fault on" and "Limit value fault off"
represents the hysteresis.
 No fault message is generated if value "Limit value fault on" is equal to "Limit
value fault off".
Adjust the texts for the universal fault inputs via the operator unit.
