6. Maintenance and cleaning
Check window adjustment
In the life of a window influences like wear,
heat and cold may induce a misalignment
of the window fitting. For this reason
window fittings should be controlled and
maintained on an annual basis. On this
occasion, additionally check whether the
distance between the magnet and the
wireless contact is large enough (min.
1 mm, max. 5 mm). If the distance is too
small or the two components collide, the
window fitting must be adjusted in order to
avoid damage to the wireless contact or
the magnet (see illustration
Step 2:
Mounting wireless contact and magnets).
Cleaning
Normally cleaning of the radio contact is
not necessary. However, if you wish to
clean its surface, you can use a dry and
soft cloth. Heavy soiling can be removed
by means of a cloth dampened with
lukewarm water.
Please do not use any aggressive or
solvent-containing detergents damaging
the plastic surface of the housing.
7. Possible sources of error
The following section enumerates the
most frequent sources of error of non-
functioning of the radio contact.
Empty energy storage
It is possible that the energy storage of the
FM.A radio contact is empty due to a long
period of storage in darkness. The energy
storage refills automatically in daylight. If
the wireless contact FM.A does not react
to the teaching procedure, it should be left
in a bright place for a few hours.
(Attention: do not expose to direct solar
radiation.)
Check the radio protocol
If several attempts to teach the sensor fail,
please verify whether the subsequent
device or the smart home system is
compatible with the EnOcean radio
protocol.
Repeat the teaching procedure
Repeat the teaching procedure, referring
to
Step 2
of the Maintenance section.
Check the radio range
If there is no connection between the radio
contact and the subsequent component or
smart home system, you should check
whether the distance is too big, whether
there are too many obstacles between the
radio contact and the receiver or whether
there are any interference fields. The best
way to do so is to unmount the wireless
contact and check its function in close
proximity to the receiver. If it works in
proximity to the receiver, but not in the
place where it is installed, it is
recommended to use a repeater in order
to increase the radio range.
Installation
In case the sensor permanently detects an
open window (which however is closed)
although the teaching procedure was
performed correctly, this may have the
following reasons:
•
There is no magnet.
•
The magnet is not correctly
positioned on the sensor surface.
