3.2 Reader

IMPORTANT
Follow the switch-on sequence
After a power-on reset (power outage followed by restoration of power sup-
ply), the controller automatically searches for connected system compon-
ents one time on restarting. System components which are not supplied
power until the controller restarts are thus unable to respond to the control-
ler's query and are not recognised.
The controller must therefore be supplied power with the other system com-
ponents at the same time or must be the last system component to receive
power.
At least one external reader is required to use the SREL3 ADV system.
SmartRelay 3 readers are ordered separately from the controller.
The controller is unable to read identification media. Up to three readers
can be connected via an RS-485 interface for this purpose. They can read
both active and passive identification media. After reading media, the
readers transmit the data to the controller, which checks the identification
medium's authorisation and triggers relevant actions as programmed. The
reader itself is unable to trigger actions and can thus be installed in less
protected areas. In the WP variant, the housing is sealed and protected
against splashing water.
Readers can either be powered through the controller or equipped with
their own power supply unit.
Too low operating voltage
When selecting the power supply, please allow for a voltage drop occurring
in conductors. A voltage drop can cause the operating voltage in the reader
to fall below the required level and malfunctions may occur. In such a case,
either the operating voltage on the controller needs to be increased or the
reader equipped with its own power supply unit.
A multi-coloured LED signals the different operating modes.
