OPEN SLOW SPEED
When the door is approaching open limit and decelerates down to slow speed before the
stop (Soft Stop), added force/speed may be required to complete opening. While this is
indcative of an improperly balanced door, this feature can be used to compensate. This
setting should only be changed from the NORMAL to the HIGH setting if door becomes
unbalanced over time and does not completely travel to Open limit. If it is a new installation,
changing the spring tension for proper balance is a required first step. Factory default is
‘NORMAL’.
CLOSE SLOW SPEED
When the door is approaching Close Limit and decelerates down to slow speed before
the stop (Soft Stop), added force/speed may be required to complete closing. While this
is indcative of an improperly balanced door, this feature can be used to compensate. This
setting should only be changed from the NORMAL to the HIGH setting if door becomes
unbalanced over time and does not completely travel to Close limit. If it is a new installation,
changing the spring tension for proper balance is a required first step. Factory default is
‘NORMAL’.

the system) or the desired number of shaft rotations (between 0.5 turns and 3 turns in half
rotation increments).
The Factory setting for this feature is AUTO. This should not be changed unless
