reverser will align the Tortoise with the direction of the reverser. Pin 1 and 8 on the Tortoise
may need to be swapped to make sure the switch point direction aligns with the polarity of
the reverser. The reverse loop gap which is encountered first after passing through the
switch should be in phase. A bi-color LED can be used in series with the Tortoise to indicate
the switch position.

J6 – Sets the current trip level. When CV49=00 [default] the trip current is 3.81 amperes if
no jumpers are installed. If J6-2 is connected to J6-1 and J6-4 to J6-3 is open, then the
current trip is 1.27 amperes. This is the correct setting for the NCE Power Cab. If J6-4 is
connected to J6-3 and J6-2 to J6-1 is open, then the current trip is 6.35 amperes. If J6-4 is
connected to J6-3 and J6-2 is connected to J6-1, then the current trip is 8.89 amperes.
J7-1 and J7-2 are the auto/manual reset input. If the connections are open, the breaker will
automatically try to reset every two seconds [default]. If the terminals are connected
together with a SPST toggle switch or N/C momentary push button switch, then the breaker
will remain off after a short until the connection from J7-1 to J7-2 is momentarily opened or
an accessory ON command is sent to the PSX-AR on-off accessory address [see Section
B item 12].
J7-4 to J7-3 is the
connection, all aspects of the PSX-AR series are optimized to operate with Digitrax
equipment. This includes the DCS50, DCS51, DCS100, DCS200, DCS 210, DCS240 and
the associated booster units. On Digitrax systems, setting OPSW #18 to "CLOSED" will
extend the short circuit shutdown to 0.5 seconds. This will help prevent the booster from
shutting down during a short circuit. See Section A item 3 for correct use of this jumper.
Note: this jumper DOES NOT affect the PSX-AR trip current. Depending on your device,
you may also need to set the trip current by adjusting CV49 or installing jumpers in J6.
J8 is the software upgrade interface and not for consumer use.
