H. Programming CV’s & Values:
Optional/Not Required!
Specific DCC Systems need to follow specific programming sequences to reliably
program a PSXX circuit breaker. See Section K for specific system instruction
The easiest way to program PSXX circuit breakers is at your work bench. Programming CV values
is done using the Programming On Main [POM] function. Refer to your DCC system manual for
specific directions on how to perform Program On Main functions.
For all systems, whenever you enter an address or CV value, you should see D17 flash. This indicates
the PSXX has received the information, stored it, and verified the stored data matches the data you sent.
1. Turn off power to the PSXX
2. Place the JP1 programming jumper on pins JP1-1 & JP1-2
3. Connect the DCC track power output of your DCC system to pins J1-1 and J1-2.
4. Turn power on to the PSXX.
5. Go into Program On Main mode [POM] for your particular DCC system.
6. Enter any address NOT in use on the layout. The PSXX does NOT use this
address, but the POM function requires an address.
7. Enter the CV number followed by the value. The small red LED [D17] on the
PSXX will blink each time a command is accepted and the CV value is stored
correctly in the CV.
8. If you make a mistake, don’t worry, just go back and program the CV to the
desired value.
9. If you are hopelessly lost, set CV63 to 42 and you can start over again with
factory default values.
10. When done, turn power off
11. Replace the program JP1 jumper to pins 2-3.
12. Turn power on to the PSXX.
I. CV Settings
CV49
Current Limit/Trip Current value
●
Default value=2
●
If CV49=0, then the Current Limit/Trip Current jumpers on J6 are enabled.
Remember to use either the Jumpers or the CV settings, NOT BOTH!
●
Setting CV49 to a value from 1-10 will set the trip rate matching the value.
●
For example:
CV49=1 Trip Rate = 1.0 amperes
CV49=2 Trip Rate = 2.0 amperes [default]
CV49=3 Trip Rate = 3.0 amperes
CV49=4 Trip Rate = 4.0 amperes
CV49=5 Trip Rate = 5.0 amperes
CV49=6 Trip Rate = 6.0 amperes
*Caution
:
continuous operations at a value of CV49=10, [10.0 amps] without the addition of heat sinks to the
output transistors may overheat or damage the PSXX. Heat sinks are available from DCC Specialties. PSXX’s can
also be ordered with heat sinks installed by DCC Specialties.
