Description
Pull this signal high to override all
commands, force the MDXII unit to shut
off output power, open the main
contactor (unless contactor hold has
been selected), and reset the unit after all
fault conditions except interlock,
overtemperature, and A/D conversion
faults. If you press the START switch
while this pin is high, the message
"Remote Off Active" appears briefly on
the control panel display, and output
does not come on.
Using this signal is the same as pressing
the output power STOP switch on the
control panel. You can clear most
control panel messages by toggling pin
14.
Use these 0 to 15 Vsignals to select one
of six internal tap settings.

Use this signal to request contactor
hold. When this signal is high, the main
and soft start contactors close and open
as output is turned on and off.
When this signal is low, the contactors
remain closed after the first time the dc
bus is energized, regardless of whether
output is being produced.
The signal is pulled up internally to 15 V
Ω
through a 10-k resistor.
