Understanding the Optional Software Features

The electronically-stored optional software features configure your MDXII unit to specific
parameters automatically each time you power on your unit.
Software options are selected at the time a unit is ordered. Your unit has only those options
ordered, not necessarily all those listed below. You can identify your MDXII unit's software
options by using the procedure explained on page 2-9.
Fast Ramp/Run
Arc-Check
(Cathodic Arc)
460/480 Volt Input
5 V Analog Input
Varc Shutdown
Enable
Voltage HALO
(VHALO)

If this option has been activated, the unit can ramp up output as
quickly as 50 ms. Normal ramp time (when this option is not
selected) is 600 ms. This option does not affect ramp functions
within recipes.
If this option has been activated, you can use the active front
panel to enable the Arc-Check feature (see "Arc-Check™" on
page 5-6).
If Arc-Check has been activated, then the Varc Shutdown
Enable option (below) is disabled.
If this option has been activated, the MDXII unit requires 460 or
480 Vac input (the typical USA input). Also, the maximum
current limit and default current arc (Iarc) trip level is 60 A.
If this option is not enabled, then the unit requires 380 or 400 Vac
input, and the maximum current and default Iarc trip level is
70 A. For more information about Iarc trip levels, see "Arc Trip
Levels" on page 5-6.
If this option has been activated, all User port analog signals
operate at full scale from 0 to 5 V, instead of 0 to 10 V.
If this option has been activated, you can select a voltage arc
(Varc) trip level at which the MDXII unit will trigger arc
handling (see "Arc Trip Levels" on page 5-6).
If this option is not active, the software does not respond to
voltage arcs (Varcs), but does respond to primary and secondary
current arcs (Iarcs). This response is different from that available
through the Arc-Check (Cathodic Arc) option. Enabling the Arc-
Check option disables this option.
If this option has been activated, then with the MDXII unit in
tap 1 and HALO.D asserted from the User port, the VOUT pin of
the User port will read 10 V for an output of 400 V. This scaling
gives you a finer resolution for better control at low output power.
For more information about VHALO, see "VHALO" on
page 5-20,
Also, if the unit is in voltage regulation mode, the LEVELIN.A
and LEVELOUT.A signals from the User port are scaled
accordingly.
