NOTE
ADHERE TO ALL STATIC PROTECTION WARNINGS IN
SECTION 7.5!
The cure for this symptom is simple. Turn off the DAU using the power switch. Remove
the protective cover on the DAU analog card rack. This is done by removing four screws.
Remove the integrator cards from the DAU. Clean the connector pins on the integrator
cards and the connectors inside the DAU. Suitable solvent would be isopropyl alcohol
(99% pure, no glycerin added), trichlorethylene, or any other DynAmp, LLC approved
connector cleaner. Reinstall all integrator cards in the appropriate slots. Reinstall the front
cover and reapply ac to the unit.
7.12 RESET SYNC ERROR OR INCORRECT DATA
If a Reset Sync error occurs, this means that the DAU is not synchronized to the rectifier.
Incorrect data will result if the DAU is not properly synchronized. When the DAU is turned
on, it automatically goes through its synchronization routine. In order for the DAU to
synchronize properly, the rectifier needs to be conducting current when the DAU is
powered up. The value of this current should be approximately 100 amps per device or
greater. If the DAU is powered up and the rectifier is not in the above stated condition, the
DAU may not establish correct reset pulse locations. The DAU will automatically adjust the
reset pulse locations when the rectifier is conducting adequate current. However, all reset
pulses may not be in the optimum location. A scanner reset will assure optimum reset
pulse location.
The “RCEM RESET” command button will also cause the Data Acquisition Unit to
synchronize to the rectifier. This may be accomplished by turning the DAU power off then
on, or by clicking on the “RCEM RESET” command button located on the laptop computer
spreadsheet.
