PROTECT IN PORT
(A2A5J1)
1
SD_A
Anode of LED optocoupler which is part of protection circuit for parallel
or series combination. Cathode of LED is connected to PARALLEL/
SERIAL PROTECT OUT PORT (A2A5J2) pin 1 (see Table 2-11). When
activated, the optocoupler shuts down the unit. LEDs from all units of the
parallel or series combination are connected in series.
2
PGOUT_C
Collector of optocoupler transistor which is part of protection circuit for
parallel or series combination. Transistor emitter is connected to PAR-
ALLEL/SERIAL PROTECT OUT PORT (A2A5J2) pin 2 (see Table 2-11).
When unit is operating normally, transistor is saturated. Transistors from
all units of the parallel or series combination are connected in series.
3
SD_RETURN
Completes return connection for the protection circuit which receives
energy from the master unit.
4
No connection
5
No connection
6
No connection
7
GND
Local power ground.
8
ALLOW EXT_ERR
Provides energy for the protection circuit (master unit only). Disabled at
power up to prevent shutdown during power up.
