DANGER
The reader and the SmartOutput module are installed in the lift. Users
identify themselves with their identification medium in the lift.
No-one can manipulate the data since communication is secured from the
reader to the controller and to LSM. When the data reach the controller, the
controller evaluates them. If there is a virtual network and connection to
LSM (Ethernet), the latest information is retrieved using the identification
medium; if not, the system used the last status saved internally. Depending
on the result of the evaluation, the controller triggers the required action,
such as actuate a relay.
Interferences in the trailing cable
Lines in the trailing cable through which data is to be transmitted must be
shielded (also see Recommended cable types [} 127]).
Power supply from cab
This connection option requires the fewest free lines in the trailing cable
and avoids voltage drops due to excessively long lines. The controller can
be installed outside the lift where it is protected in a place, such as the
engineering room.
The reader is not powered via the controller. Instead, it is connected to the
existing power supply in the lift cab, which provides electricity for lighting,
doors and other elements. The voltage may need to be converted with a
power supply unit, so that it is within the specified voltage range for the
SmartOutput module and reader (see Properties [} 121]). The voltages
supplied to the individual components do not need to be identical. It is thus
possible to operate the controller with 12 V while the reader in the lift is
operated with 24 V.
In this specific case, four lines are also needed to supply power to the
cab.
Electric shock due to mains voltage
An electric shock may be caused when connecting the non-hazardous
earth (low voltage) to a conductor which carries the mains voltage.
1. Only use conductors with a low-voltage potential (< 42 V) as a common
earth cable!
2. Protect live cables, so people do not touch them accidentally!
