Keypads (MMIs):
Trips shown as MMI displays in the tables above, i.e. , can be disabled using the
keypads in the TRIPS menu. Other trips, as indicated, can be disabled over the Comms.
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 04A0, then this represents:
a “4” 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 SWITCH, ANIN FAULT, MOTOR STALLED and
INVERSE TIME.
In the same way, the AUTO RESTART TRIGGERS+ parameter set to 04A0 would represent
OVERSPEED, ANIN FAULT, DESAT OVER I
and 10V FAULT.
