MiniMax-79/159
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
sensor 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 open-
ing.
Please observe the following mounting guidelines:
Emitter

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.

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!
Receiver

The black plastic profile with the curved
surface is at the front of the edge. This side
has to "look" at its companion piece, which is
Please note that the receiver (the one with the
blue connector) can be sensitive to "foreign"
light. No other source of external light,
Never scratch the curved front surface as
this is the lens that forms the light path! At
the installation site, leave the edges in the
protective cardboard box / protective hose
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
sill!
Do not bend or twist the edges!
Oil may damage the cable. Contamination
must therefore be avoided at all times!
