SECTION 3: COMMON QUESTIONS & ANSWERS
(Version 3 software)
*** QUESTIONS ABOUT CONTROL SET-UP
***
Q1-1How do I reset the stroke stored in the control?
A1-1
instruct the control to do a full 'learn' cycle by pressing
and holding
the SET button down while momentarily pressing
RESET, or hold the SET button down while powering up the control. The control will restore all the factory default settings, learn
the new stroke, and store all the information.
Q1-2
How do I verify the stroke that a particular control is set to?
A1-2
Locate the tS parameter in the parameter list, and press SET to view it. The stroke will be displayed in inches. The
total stroke can also be modified via the UP and DOWN buttons, but it's not recommended - we suggest letting the control determine
the stroke automatically with a full learn cycle instead.
Q1-3Can the control re-learn the stroke without changing any of my other settings?
A1-3Yes. In Version 3.01 & later, holding both the SET and UP buttons while momentarily pressing RESET or powering up
will retain all of your present settings except for the stroke.
Q1-4
What are the default settings in the parameter list when I force the control to do a full learn cycle?
A1-4Refer to the chart on page H603.2, which shows all the defaults.
Q1-5I changed some settings, but everytime I reset the control or there's a power loss, the control goes back to its
original settings! What's going on?
A1-5You must remember to
save
the settings you decided on before you leave the job site! To save your new settings into
permanent memory, the toggle circuit must be on (door must be in normal operation). Push and
hold
the SET button until the
display shows dS. Your new settings are now stored. Data is only stored when the door arrives at the fully closed or open
positions; also, note that normal door operation is disabled until the SET button is released.
Q1-6
I would like to move the point where the door goes into open check.
A1-6Locate the CP (Check Point) parameter and modify it. This parameter is in inches of stroke and can be set from 50% to
90% of the total stroke learned on startup.
Q1-7
I changed the total stroke manually, and the control also moved my check point. Why?
A1-7
This is normal, and is done to properly relocate the open check point. You should have set the total stroke first, or
allowed the control to automatically learn it, then reset the open check point to your desired value.
Q1-8
I changed some parameters and really messed things up. How do I get back where I started?
A1-8Assuming that you haven't saved the new "messed up" parameters, simply pressing RESET will restore all of the
settings you had before you started tinkering. If you did a data save, your original parameters are lost, and you will have to do a
complete learn cycle to get back to a parameter set that at least works in your door.
Q1-9
The door goes through its full learn cycle, then the control starts flashing SF until reset. Why?
A1-9
This code indicates a'Stroke Failure' - some encoder pulses were found, but not enough. Check the encoder and
associated wiring carefully, and verify that the encoder wheel and other mechanical parts are not slipping. The minimum stroke
is 12" if Horton's standard S2001 gear drive and 3.183" drive pulleys are in use. (Note: Version 3.02 & earlier have a 20" stroke
minimum.)
Q1-10
When I power up the control, the door closes slowly on its first run, then the display starts flashing nS. What
gives?
A1-10
This stands for 'no Switch' -the close monitor switch is not supplying a "door fully closed" indication to the control.
Check your switch, its mechanical adjustments, and its wiring.
Q1-11
My door seemed to setup properly, but then it refused to close and the display is showing St. What's wrong?
A1-11
This is the Stop code -the pushbutton "stop" input (marked KEYSW, pin 16 of CN2) is active. This is a
normally closed
i
nput - pin 16 must be jumpered to common (pin 15) for the door to work if a stop button isn't installed.
Q1-12There's a red LED marked +100 next to the display that comes on when some parameters are accessed.
A1-12
This LED shows that you must add 100 inches (or seconds) to the display value. Think of it as a third '1' digit in front of
the other two.
Q1-13I I
nstalled a very heavy door (over 400 pounds), and/or amusing a 1/2 hp
heavy-duty motor, and the braking
seems very abrupt. Why?
A1-13
The standard braking on the C2150 control is optimized for light to medium weight doors, and will suffice for the vast
majority of applications. When installing a very heavy door, you should set the Hd (Heavy duty) bit to the ON
position. This will
change the braking to a more gentle curve and minimize wear and tear on the door and operator. Note that with the different
braking, you may have to move the check point back and/or slow the door down a little to achieve smooth operation.
Ql-14I installed a switch for partial opening operation and set the PO parameter for 24", but I'm getting 48" of partial
opening on my bi-part operator. Why?
A1-14All
measurements in the C2150 control are based on inches of
stroke,not inches of door opening. The 24" setting will
yield a 24" door opening on single-slide operators - but for bi-part doors, you would set PO to 12".
