AUTO-CONTACTOR SOFTWARE

This auto-contactor software version includes a software change that allows the contactor to
close automatically when the supply has no active faults. If a fault occurs, the contactor opens
normally and closes again automatically once the fault is cleared.

Custom Hardware

SETPOINT.D

Normally, User port pin 3 (STPT OK.D) goes low and stays low to indicate when the power
supply is out-of-setpoint. However, with this hardware option, the pin has been modified. If
the output power is turned off, this signal goes low temporarily and then quickly goes high.
This quick low/high indicator from pin 3 applies only to a "power off" situation and not to an
out-of-setpoint condition.

DEKO

With this hardware option, the MDXII 18P unit's Varc-detection circuit has been modified
(de-sensitized) to lengthen Varc detection time. This means the power supply does not detect
or react to micro arcs during a process. See Appendix A for more information about the
MDXII 18P power supply. For more information, see "Arc Delay and Density" on page 5-6.
