Installation
The installation should be done in the following se-
quence:
1. Switch main power off and mark clearly
that this elevator is out of service
For your own safety, turn the power off before you
start working on the elevator! Clearly mark that this
elevator is out of service.
2. Mount the emitter and the receiver
The emitter and the receiver edge can be mounted
either to the door wings, to the door wing and the
slam post, or to a frame that is attached to the car.
Please note that objects smaller than the sen-
sor spacing may not be detected! In the USA and
Canada, MiniMax type 79 shall be used only if the
emitter and receiver edge are each set back from the
leading edge of the door and/or slam post by at least
one sixth of the full door opening.
Please observe the following mounting guidelines:

Depending on the environment temperature, the MiniMax edges may appear bowed. This is a natural phenomenon due to differing expan-
sion coefficients of the plastic and aluminum components of the edges. Do not try to bend or twist the edges straight.

blue connector) can be sensitive to "foreign" light. No
other source of external light, including the emitter of
any other light barrier system, should be directed
towards the receiver edge. Although MiniMax is very
tolerant of bright sunlight, it is better to mount the
receiver edge so that no sun light shines directly into
the curved front area of the receiver lens. It is similar
to human eyesight: while you may have visibility
even if looking directly into the sun, it is harder to see
clearly. Therefore, it is always better to have the sun
at your back!

for as long as possible!
The curved surface of the emitter and the
receiver should point to each other face-to-
face!
Align the optical axis of the emitter and the
receiver as close as possible in order to
achieve best performance (± 5°)!
The recommended distance between the
door sill and the bottom of the sensors is 6
mm (¼"). A greater distance reduces safety
due to an unprotected area right above the

must therefore be avoided at all times!
