9 A SAFE DOOR
The safety of an Automatic door is achieved with careful basic adjustments.
Low speed, higher speeds increase the force applied to any obstruction. The speed
should be set so that users are able to pass through the door unhindered, with the
speed set as slow is as reasonable possible. The position of the input devices
are also a factor i.e. where ever possible, they should see users approaching and
start to open allowing the door to open slowly.
The door operator should always be set to the lowest possible force setting,
ensuring that the door operates smoothly, but equally does not have excessive
force for the application.
In all cases the door size should be set to the smallest possible setting, S small, M
Medium, L Large, remembering the half steps achievable with the custom setting
we effectively have S, S+, M, M+, L, L+. We should always remember that these
force setting also has an effect with the inbuilt safety settings, i.e. the more force
applied, the lower the sensitivity, hence should the door make contact with an
obstruction it will apply a greater force is the door weight is set higher.
We recommend that safety sensors are fi tted to all applications, particularly on
the driven side, opening face in the case of a DA430.
Higher speeds are only achievable when full safety is specifi ed.
