CV49 Current Limit/Trip Current value

●

Default Trip Rate = 1.8 amps

●

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 = 0.9 amperes

CV49=2 Trip Rate = 1.8 amperes [default]

CV49=3 Trip Rate = 2.7 amperes

CV49=4 Trip Rate = 3.6 amperes

CV49=5 Trip Rate = 4.5 amperes

CV49=6 Trip Rate = 5.4 amperes

Low Current System Trip Current Settings:

●

For the Digitrax Zephyr [DCS50, DCS51, DCS52], setting values of CV49=01, 02, & 03 is OK.

●

The NCE Power Cab should use the default value of CV49=02.

●

For the Power Cab CV49=1 is ok too.

●

Most 5 amp boosters should be happy with CV49 = 0-5
