· In case the communication to the controller is lost, the device can be
configured to go into a defined state.
· Default setting mode is “keep last setpoint”, i.e. in case of communication
loss, the device controls to the last received setpoint.
· If the backup mode is enabled, it can be configured as follows:
o go to a predefined backup position
o
keep current position
Restarting
the device
256 Restarting is possible by:
· Power-reset (turning operating voltage off and on) or
· by “ReInitDevice” command.
à Device re-initializes and sets all process values to defaults.
Reset
The actuator supports the following re-initialization / reset behaviour:
· Local reset by push-button
· Remote reset: Using “RemoteFactoryReset” command.
Effect of reset:
Process values: set to ex-works default values.
· Parameters:
o Application and actuator parameters are set to factory defaults,
o Network parameters are reset only in case of local reset, not by remote
reset (otherwise loss of communication).
·
Not reset are: Counters, status flags, device info, and factory data.
Self test
256 When triggered, the self test drives the actuator to the detected limits and sets
the flags in register 769 according to the result (bit 09 = 1à”failed” or bit 10 = 1
à “passed”).
The self test is not passed when the limits were not reached from the lower
end (results in jam). If the Min/Max limits can be exceeded, the self test is not
evaluated as failed.
