Door Types and Considerations
IMPORTANT - PLEASE READ THIS SECTION CAREFULLY TO
ENSURE THAT THE DOOR YOU INTEND TO AUTOMATE, MEETS
THE REQUIREMENTS FOR SUCCESSFUL AND TROUBLE-FREE
OPERATION!
Door Brands
This product is designed to operate, primarily with common types of roll-up door makes
and models found in the South African market. These include the WISPECO™ brand
and the KRAZI-DOOR brand. Other types are suitable, provided they meet the criteria
listed below.
Door Type
In general, the DCC02 is designed to operate the standard low-cost roll-up doors
commonly used in domestic applications- doors which are fabricated from thin
laminated steel or aluminium. It is not recommended for use with the 1970’s era heavy
steel roll-up type doors, which are much heavier than the common roll-up door types.
Door Sizing
The DCC02 is designed to drive a single door by itself. For particularly wide doors, the
product must be installed in the centre of the door, by fitting an additional adapter
wheel. It is not possible to fit two motor head units to a single door. The height of the
door is not a factor, therefore, standard height doors as well as “caravan doors” are
suitable candidates for this product.
Door Condition
The condition, and quality of the installation of the door plays a MAJOR role in whether
the installation of this product (or any other garage door automation product) will be
successful or not. Common problems that cause this product to fail, either immediately,
or after some time include:
Doors that are not true-
These are doors that are installed skew, leading to the
formation of gaps at the bottom when the door is fully closed. The DCC02 does
close the door completely to the floor but it was
not
designed to drive the door
curtain into the floor to seal against flooding etc...
Doors that are not balanced-
These are doors that, although they appear to be
light to move by hand, either suffer from tight spots during travel, or get stiff in
cold weather. The DCC02 can compensate to a large degree, for cold stiffness
but beyond this, will consistently go into over-current to protect the motor.
Doors that are too light-
A frequent problem is a door that is too light, causing
the door to unravel at the top, when closing. In these cases, it is necessary to add
weight to the bottom of the door, in the form of a steel bar or angle iron. Doors
that are too light also cause the system to exhibit various symptoms. These
symptoms include moving short distances, stopping shortly after opening, etc..
