GALaxy eHydro Elevator Controller

4.10.3 Car Trace Screen

The controller continually stores 168 bytes of critical data every 20 milliseconds (can be set to 10, 20,
30 or 40) in a 500-frame circular trace buffer. This continues until a command is given to stop storing in
which 35 additional frames are stored and then the update is stopped. The purpose of this buffer is to
capture 465 frames of data prior to an event and then 35 frames after the event.
The user can manually stop the trace buffer while viewing data in the Elevator Status display by
pressing ENTER and then Mode for the Trace Popup window and then hitting ENTER to stop the trace.
The trace can also be stopped by setting up a trace trigger from an occurrence of a fault or state
change.
Once the trace buffer is stopped, the Elevator Status screens becomes the Trace buffer screens. The
Elevator Status screen will stay in the trace mode until the trace is restarted.
The trace update rate and trigger parameters can be altered by the user to enable the capture data for
a specific problem. The trace setup is accessed from the Software Utilities menu and is shown below:
