7.1.

 

COMMON PROBLEMS 

When  encountering  difficulty  in  achieving  successful  operation  of  the  DBT12,  there  are  some 

problems  which  are  easily  identified  and  solved.    The  following  list  is  not  intended  to  be 

exhaustive. 

SYMPTOM 

POSSIBLE CAUSE/SUGGESTED ACTION 

Upon  initial  power-up,  the  unit  does  not 
behave in accordance with the Section 6.1 
description (no display or fan). 

 

Ensure  dock  power  is  available.    Check 

pedestal and shore cord circuit breakers. 

 

Have  input  power  to  the  unit  checked  by  a 

qualified electrician. 

The unit powers-up in accordance with the 
Section 6.1 description, but does not close 
contactors and output voltage and power. 

 

Review the unit display for an input voltage 

between 167-270VAC. 

The unit trips to a POWER OFF state and 
reports  the  message  “FAULT:  Latched 
OFF, Recycle Power” 

 

Review Section 0. 

 

7.2.

 

SOFT-START INHIBIT 

If  the  unit  is  turned  off  within  approximately  5  seconds  from  the  time  it  was  turned  on,  at  the 

next  power  up  the  following  screen  is  displayed.    The  soft-start  inhibit  timer  will  count  down 

from 60 seconds and the unit will then proceed with normal power up. 

 

 

 

 

SOFT-START INHIBIT COUNTDOWN:59 seconds 

If Converter Turn-On Problem Persists, 
Please Contact ASEA Factory Service Rep
