3.3.9.1 REMOTE SHUTDOWN
Functionality of a standalone unit can be shut down using a remote signal applied to the PRO-
TECT EXT. PORT as shown in Figure 3-2 or 3-3. Functionality of a multiple unit configuration
(parallel, series or series-parallel) can be shut down by applying a remote signal to the master
PAR/SER PROTECTION PORT as shown in Figure 3-2 or 3-4. When the signal is momentarily
active (minimum 100 microseconds), power transfer between input and output is stopped (both
input and output internal modules are shut off). This condition is latched and shuts down unit
functionality. The unit remains powered, but no output is available and the front panel
POWER/FAULTLIMIT LED will turn red (fault). The unit must be powered off, then on again to
restore normal operation. This feature can be used a “panic” control or as an interlock shut
down for a system with other equipment.
For multiple unit configurations, automatic shutdown upon accidental removal of the cable at the
Master PAR/SER IN PROTECT PORT can be implemented with a simple internal modification.
