BOP as a power amplifier (PAR. 3.4.3) and 3) establish the protection limits (PAR. 3.4.4). An
output signal proportional to output current is also provided for external use (PAR. 3.4.5).
3.4.1
REMOTE OUTPUT OFF
There are two ways two turn off the output using remote signals: (1) Remote Shutdown which
requires the unit to be turned off, then on in order to restore operation and (2) Remote Standby
which sets the output to OFF, putting the unit in STANDBY status.
3.4.1.1
REMOTE SHUTDOWN
A standalone unit can be shut down using a remote signal applied to the PROTECTION EXT.
PORT as shown in Figure 3-12 or 3-13. A multiple unit configuration (parallel, series or series-
parallel) can be disabled by applying a remote signal to the master PAR/SER PROTECTION
PORT as shown in Figure 3-12 or 3-14. When the signal is momentarily active (minimum 100
microseconds), power transfer between input and output is stopped (both input and output inter-
nal modules are shut off). This condition is latched and requires the unit to be turned off, then on
again to restore normal operation.
