Design of wireless range
The wireless signal is attenuated on the way from the transmitter to
the receiver. In addition, the wireless signal is attenuated by obstacles.
The degree of attenuation depends on the material of the obstacle.
Ideally, with a direct line of sight, the wireless range will be greater
than 300 m.
Penetration of radio waves:
Material Penetration
wood, gypsum, glas uncoated 90...100%
brick stone, press boards 65...95%
armoured concrete 10...90%
metal, aluminium lamination, water 0...10%
The following influences may reduce the wireless range as well:
- High frequency interference.
- WLAN or Bluetooth networks (or comparable 2.4 GHz networks) in
the vicinity.
- Inappropriate antenna arrangement.
Radio operation
Transmission is carried out in the licence-free 2.4 GHz ISM
frequency band.
NOTICE
Simultaneous operation with WLAN or Bluetooth
networks is possible. If there are repeated dis-
turbances or radio disconnection, conduct a radio
network planning.
NOTICE
Portable and mobile HF communication equip-
ment may negatively affect the functionality of
the NGF radio system. This may lead to a loss
of single telegrams or of the wireless con-
nection. If needed, limit the number of mobile
communication equipment in the vicinity of the
NGF radio system.
To achieve optimum availability, install and operate the transmitter
and receiver with a minimum distance of 1.5 m and a maximum dis-
tance of 300 m to each other.
Coexistence and parallel operation of NGF24 systems
If there is more than one 2.4 GHz system in the same area that sends
radio transmissions on the same frequency and at the same time, the
telegrams will collide.
Troubleshooting
Possible causes for disconnected/missing wireless connection:
- The devices are out of wireless range.
- The battery charge of the transmitter is empty or no batteries have
been inserted.
- The transmitter is in Deep Sleep Mode.
(Press the pairing button to wake up the transmitter.)
- The receiver and/or transmitter is in error state.
(Try the power cycle of both devices.)
Maintenance and cleaning
With careful installation as described above, only minor maintenance
is necessary. steute recommends routine maintenance as follows:
1. Check the enclosure and connection cable for damage and soiling.
Clean enclosure on the outside only. Clean enclosure with house-
hold cleaning agents. Do not use compressed air to clean.
2. Check the plug-in connection.
3. After each start-up, perform a function test.
If a battery is present, check the battery charge level.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
Repair
NOTICE
Alterations to the device may cause irreparable
loss of function. Do not alter the device.
Return damaged devices to steute.
