    Manual 26112 ProAct Digital Plus Drive Current Limitations The current to the coil is limited to prevent damage. A transient and a steady state limit are used. The transient current limitation is active during a transition in position output. After a short delay (about 3 seconds), the steady state limit is activated if desired position is not reached.

    Configuration parameters can be monitored at any time. Unit does not need to be shut down for configurable parameter monitoring. The ProAct Digital Plus will do nothing—the current to the actuator controller will remain off—until it has a valid configuration.

    Program changes and tuning/calibration are password protected. The password is a simple ‘keyword’ password that is fixed and cannot be changed. It is intended only to prevent inadvertent changes to the ProAct Digital Plus. One fixed password is available per mode. This password is required only to make changes (writes), program monitoring does not require a password.

  • Page 50: Chapter 6. Diagnostics

    Shutdowns Detection and Annunciation A shutdown condition forces the actuator to a predetermined position regardless of the demanded position. The ProAct Digital Plus can be programmed to go to one of three predetermined states when a shutdown condition is detected. A shutdown condition can be configured to power-down (disable the current driver to the actuator), go to min (0 %) position, or go to max (100 %) position.

    Event Log The Event Log provides a historical logging of ProAct Digital Plus alarms and shutdowns. It is capable of storing all events, along with the number of times that event occurred and the relative time of the first occurrence. The log will store its information in non-volatile memory to retain the data on power loss.

    Manual 26112 ProAct Digital Plus Service: Status Errors—Shutdowns The Status Errors—Shutdowns tab sheet contains status information on all monitored actuator shutdowns. Values that are TRUE, indicate the shutdown condition is active—forcing the unit from normal (running) operation into a shutdown mode. The Shutdown indication is non-latching and returns to false when the condition no longer exists.
