PRESENCE DETECTOR / MOTION DETECTOR WITH CONSTANT LIGHT LEVEL CONTROL

Product and functional description
The UP 258E11 is a presence/motion detector with integrated 2-point light control. The UP 258E11 device communicates via KNX/EIB with actuators or other KNX devices. It is designed for mounting on the ceiling. Owing to its tilting sensor head, the UP 258E11 can be aligned with the required capture area. The main application for the device is automatic lighting control in an office workplace.

The UP 258E11 senses the presence of a person or that there is no longer anyone in its detection area. The detector signal can be analyzed via two separate communication channels, termed motion detector and presence detector.
Additionally, the UP 258E11 provides an output for control of HVAC applications. For example, this function can switch systems that are used for heating, ventilating and
air-conditioning control (HVAC) of the room from “Energy saving mode” in an unused room to “Comfort mode” in an occupied room and back to “Energy saving mode”
when the room is again unoccupied.For each detector function block (presence, motion,
HVAC) 4 communication objects are available, in total 12 different communication objects. Depending on configuration, one or two KNX telegrams are sent onto the bus when motion is first detected and when, after the last motion was detected, an overshoot time has expired.
The values of the communication objects are configured for each functional block (motion detector, presence detector, HVAC-detector) via corresponding parameters. Each time a presence is detected, the overshoot time is started. Its duration is separately configurable for each functional block. The end of presence is determined by the end of the overshoot time.
The duration of the dead time is also configurable per functional block. It is used to protect the actuators that are connected to the detector. If a presence is detected
during the dead time, neither telegrams are sent nor the overshoot time is started.
In the following the telegrams, which are sent at the beginning of a presence, are called A and B, the telegrams, which are sent at the end of a presence, are called C and D.
Operating Sequence

After the device has detected a presence, telegram A issent immediately. If it has been configured to send also a telegram B, then telegram B is sent after the configured time (optionally also cyclically).
If there are no motions any more, at the end of the overshoot time telegram C and (if configured) telegram D are sent. Telegram D can also be sent cyclically. If there are motions while the overshoot time is running, the overshoot time is restarted.
