Reduced field range is possible due to metal objects in the immediate vicinity
of the device.
Ensure that no metal objects are located in the immediate vicinity of the
device.
Malfunction may be caused by two readers influencing one another.
If the distance is too short, an authorised locking medium can be delayed or
remain undetected.
Assemble the devices at least 50 cm apart from one another.
Malfunction may be caused by the presence of external systems.
External systems can emit interference fields. This can cause an authorised
locking medium to be delayed or remain undetected.
Ensure that external systems do not influence the device.
Qualification of the staff
People working on and with the devices must have a basic knowledge of
electrical engineering so they meet the following requirements:
They can assess dangers which can result from voltage and current.
They can make proper electrical connections with low voltages (AC≦50 V,
DC≦120 V in accordance with VDE 0100, IEC 60449).
They can implement electrical connections with nominal voltages up to 1000
volts (normally 230 V) in line with VDE 0100 if the power supply
unit/transformer is connected directly and not to a properly installed socket.
They are capable of understanding how the devices work and how the
individual components interact.
