Troubleshooting Guide

The following is a thorough guide to solving problems that occur with the DCC02. It 
is split into two sections, one for diagnosing troubles during limit programming, the 
other for diagnosing problems during normal running. These are by no means 
exhaustive lists of all the possible combinations of problems that occur, but these 
guides do cover over 90 percent of the problems that our customers experience with 
this product and how to best resolve them.

Always work through these guides first when solving problems, before calling 
technical support.

 This will allow us to provide the best possible support to every 

single customer. Where a particular problem is not described in these guides, you 
are encouraged to call us or e-mail us for prompt resolution to your query. We also 
publish a FAQ on  our website, be sure to have a look at that as well for any late-
breaking issues that have come to light since publication of this manual.

SECTION A: LIMIT SET-UP TROUBLESHOOTING

Problem                                    Likely Cause(s)             Possible solution(s)

Cannot set the door up, system 
constantly beeps four times when 
power is applied.

• Power Problem
• Problem with 
  interconnecting cable
• Main fuse (F2) in console 
blown or fatigued.

• Check fuse F2
• Check the wiring, especially if   
   you lengthened the cable. 
   Check for voltage across the 
   two outer terminals of the 
   interconnecting cable. If none 
   present, replace F2 in the wall 
   console.

The door moves a short distance, 
then stops with an error beep 
when attempt is made to program 
the limits.

• Door not balanced
• Spool wheel bent 
• Dirt/foreign matter on 
  encoder wheel.

• Check the door, if there’s a 
   tight spot during upwards 
   travel, you will need to fix it.
•  A bent spool wheel pulls the 
   driving wheel away from the 
   motor chassis, leading to it 
   coming off the chassis 
   altogether and the encoder no 
   longer rotates. Replace spool 
   wheel or fit an adaptor wheel 
   available from the place where 
   you purchased this product.
• Sometimes, dust and dirt from 
   the installation gets onto the 
   encoder wheel, blocking the 
   holes and the system can no 
   longer measure distance 
   traveled. Ensure the area is 
   clean and free of dust/foreign 
   matter.
