Temperature Compensation: (*Factory Setting, do not change)
The Temp Comp is a factory setting that should not be changed without consulting
Dado Door. The metal enclosure has a certain ambient temperature due to
electronics in the box and the room temperature combined. The motherboard has
an onboard digital thermometer which is checking the temperature constantly.
In electronics, temperature affects how circuits behave, and the previously
mentioned Trip Level settings are no exception. If the temperature changes in an
environment, then the Trip Levels will tend to change as well, throwing off the
calibrations made at an earlier time at a certain temperature. The Temp Comp is
part of an internal algorithm that uses the digital thermometer to track the room
temperature and compensate for changes, thus keeping the Trip Levels somewhat
stable over a range of temperatures.
Set Close Position:
The Set Close Position is the actual distance the door will travel towards the closed
(stopping) position STARTING from the fully open (HOME) position. Upon booting up
the system, the door will travel to a HOME position(fully open), and will contact the
Home Switch on the track. The default Close Position settings is 10,000, which is 20"
of travel. Zero is the fully open position at the point of contact of the door to the
HOME switch. The system uses digital encoders located on the motor to keep track of
where the motor/door are in a highly precision manner. The Set Close Position value
shown in the display will equate to approximately 1” = 500. As an example, if the
value says 5000, then calculate 5000/500 and you can assume that the door will
move 10”. If the value is 10000, then the door will move 20” and stop(10000/500). 1/2"
= 250, 1/4" = 125 1/8" = 62 1/16"= 31 1/32" = 15.
This setting is one of the first important settings on a new install.
**Change this setting
in SMALL amounts and WORK YOUR WAY UP TO the final closed resting point, DO NOT
go past the point where the door bumps the jamb**
. It is never a good idea to allow
the door to contact the wall or jamb when closing. If the door does bump the wall,
immediately power off the system to avoid stressing the motor and motor driver. The
Closing Trip Level ‘may’ catch the overshoot and retract the door if it hits the jamb,
but, on a new install, the Closing Trip Level may be set too high to detect the jamb
and the system could be stressed causing damage.
Keep in mind, that if you change the Home Switch location on the track at any time
AFTER establishing the Set Close Position, then the Set Close Position will have to be
re-calibrated BEFORE running the door again. If the Home Switch is moved closer to
the door jamb on the closed side of the door, then the door may hit the jamb based
on the distance it has been programmed to move. If the home switch is moved,
change the Set Closed Position to a lower value so that the door will be sure not to
hit the jamb, then start over on the calibration and work your way up to the actual
closed position again.
