Maintenance

The Micro MF is designed for maintenance free
operation. Periodically, the Micro MF system should
be checked to ensure that:
-
The optical sensor elements are clear of dirt and
dust. If necessary, clean the front surface with a
soft towel.
-
The edges continue to be fastened securely to
the door wings or other mounting surfaces.
-
The cables are fixed properly e.g. in accordance
with mounting kit instructions.
Important notices:
Never use any solvents, cleaners or mechanically
abrasive towels to clean the edges. The optical
elements can be damaged!
Never use high-pressure water to clean the edges!
Do not scratch the surface when cleaning the edges!
Failure to follow these important notices may result in
damage to your Micro MF system, potentially making
it unable to detect persons or objects effectively.

Potential cause / remedy
Make sure power is connected to the emitter edge (14 to 30 VDC)

Make sure power is connected to the receiver edge (14 to 30 VDC)

Make sure that the emitter and receiver edges are aligned

Ensure that the optical elements of the emitter and receiver face one another

Check to make sure that the protective field is clear of obstruction

Check that the test input is connected to the test output signal of the door control unit

and that the signal level and logic (HIGH/LOW) are correct.
If the test input is not used, connect it permanently to U

Make sure that the receiver cable and edge are located away from sources of electro-

magnetic interference (EMI) e.g. door inverters and door drives
Filter potential noise sources with external relay module or power line converter

Move the receiver cable away from sources of electrical noise

Ensure that there are no objects that enter the area between the emitter and receiver

when the door operates
Ensure that the emitter and receiver are correctly aligned and remain in alignment

during door closure (e.g. that vibrations do not cause edges to become misaligned)
Ensure that the optical elements are free of dust or dirt. If necessary, clean using a

soft cloth.

Disposal

Should you need to replace your Micro MF system
(e.g. due to damage beyond repair), ensure that the
replacement device is in accordance with the door or
other device manufacturer's specifications and any
applicable local, state, regional or national standards
and regulations.
The Micro MF system is designed and manufactured
to have minimum impact on the environment. It uses
only a minimum amount of power and natural
resources. Unusable or irreparable devices should
always be disposed of in accordance with applicable
local, state, regional or national standards and
regulations. We recommend 'electronic recycling' of
these devices. Always act in an environmentally
responsible manner.
