Hexadecimal Representation Of Trips - Parker AC890 Product Manual

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 ACTIVE WORD 1 parameter is
02A8, then this represents:
a "2" in digit 3
an "8" and a "2" in digit 2
(8+2 = 10, displayed as A)
an "8" in digit 1
This in turn represents the active trips BRAKE RESISTOR, MOTOR STALLED, INPUT 1 BREAK and HEATSINK TEMP,
(an unlikely situation).
( In decimal representation, 02A8h is 680d
680 = 512 + 128 + 32 + 8
This in turn represents the active trips BRAKE RESISTOR, MOTOR STALLED, INPUT 1 BREAK and HEATSINK TEMP)
In the same way, the ACTIVE WORD 2 parameter displaying 02A8 would represent CURRENT LIMIT, DESAT (OVER I),
TRIP 22 and 24V failure, (another unlikely situation).
The hexadecimal value is used over comms, however, pressing the M key whilst displaying the hexadecimal trip value will
show the list of all trips and their current values
