OPERATIONS AND FUNCTIONS

Contactor Closure

Compared to the MDXII 15k and 30k power supplies, the contactor closure operation in the
18P supply is independent of 'on' commands. This means you control contactor closure and
you must close the contactor before requesting or issuing an output 'on' command.
To close the contactor from an AE Bus or Profibus serial port, use Command 30. From the
User port, use pin 16 (CHOLD.D).
Note: Because most faults open the contactor, you must close the contactor after a fault occurs
to restore the supply to the ready state.

Deko/Varc

If your MDXII 18P unit features the Deko custom software, then the Varc detection time is
longer than typical. For more information about Deko, see "Deko" on page 2-24. For details
about detection times, see "Arc Delay and Density" on page 5-6.
