APPENDIX – CHAIN TENSIONER ADJUSTMENT
SIGNS OF A LOOSE CHAIN TENSIONER
•
Opening or Closing door movements may be erratic
•
The door may reverse open on its own during the closing cycle
•
When a setup is launched, the door may appear to open a few degrees at a time, especially
as it is just beginning to open
•
Door may not open to its full open position - it may stop short and then close, as it thinks
there was an obstruction
•
Operator may make a loud clicking noise - this is created by the chain jumping on the
sprockets
•
There may be a "lag" between operator movement and door movement - this is due to the
chain "slack" being taken up before door movement
•
Door may go through a setup correctly but then will show a flashing red error LED upon
completion of setup, or upon the first attempt to open
•
If chain is excessively loose, it is possible for the chain to become bound up on itself, thus
preventing automatic door movement - this will usually happen on the closing stroke
•
Abnormal noises may come from the operator as you use the door manually
•
Wear marks may be evident on the body of the operator where the tensioner bolt has
slipped
