4.5 EXTERNAL–OFF Control
The EXTERNAL–OFF control input provides the same functionality as the OUTPUT
switch on the front panel. When asserted, it will turn off the output converter, discharge
the output capacitors with the downprogrammer, and reset the OVP and FAULT
monitors. It is opto–isolated from the other signals of the REMOTE ANALOG
INTERFACE.
4.5.1 EXTERNAL–OFF with Voltage Source
EXTERNAL–OFF is asserted when a voltage within the range of 2–30 VDC is applied
from Pin-14, positive, to Pin-2, return, of the REMOTE ANALOG INTERFACE
connector. Refer to Figure 4-9. The voltage source and switch could be replaced with
a logic gate for digital ON/OFF control.
CAUTION
The maximum float potential of either line of the EXTERNAL–OFF
control signal with respect to any other signal of the REMOTE
ANALOG INTERFACE is 60V(PK).
