9.3.10 Reset behavior
The actuator supports the following re-initialization / reset behavior:
• Local reset by push-button: cf. section 2.4.2
• Tool-reset, cf. section 5.1.2
• Remote reset: Using “RemoteFactoryReset” command.
Effect of reset:
• Process values: set to ex-works default values.
• Parameters:
- Application and actuator parameters are set to factory or OEM defaults,
- Network parameters are reset only in case of local reset, not by remote
reset (otherwise loss of communication).
• Counters are not reset.
• Status flags are not reset.
• Device Information and Factory Data are not reset.
9.3.11 Self-test
The actuator supports a self-test. When triggered, the self-test runs the actuator to
the detected limits and sets the flags in register 769 according to the result (bit 09 =
1→”failed” or bit 10 = 1 → “passed”).
• The self-test is not passed when the limits were not reached from the lower
end (results in jam).
• If the limits can be exceeded, the self-test is not evaluated as failed.
9.3.12 Configuration check
The actuator supports a basic configuration check for the relation between Vmin
and Vmax: Vmax must be greater than Vmin, otherwise this is regarded an invalid
configuration. Tolerance level is 2% difference.
In case of an invalid configuration, the LED blinks red and the flag “invalid
configuration” in the status register (bit 11 in reg. 769) is set to “1”.
