Trips and Fault Finding 7-9
DC590+ Series DC Digital Drive
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, if the HEALTH WORD parameter is 01A8 then this represents a “1” in digit 3, an “8” and a “2” in
digit 2, (8+2 = 10, displayed as A) and an 8 in digit 1. This in turn represents the active trips FIELD FAILED,
ENCODER FAILED, OVER VOLTS (VA) and HEATSINK TRIP (an unlikely situation).
