Hexadecimal Representation of Trips
When more than one trip is to be represented at the same time then
the trip codes are simply added together to form the value displayed.
Within each digit, values between 10 and 15 are displayed as letters
A to F
For example referring to the tables above, if the AUTO RESTART
TRIGGERS parameter is set to 03A0, then this represents:
a “3” in digit 3
an “8” and a “2” in digit 2
(8+2 = 10, displayed as A)
an “0” in digit 1
This in turn represents the trips BRAKE RESISTOR, ANIN FAULT, MOTOR STALLED and
INVERSE TIME.
In the same way, the AUTO RESTART TRIGGERS+ parameter set to 03A0 would represent
BRAKE SHORT CCT, ANIN FAULT, DESAT OVER I
and 10V FAULT.
