Presence Detetor ECO-IR 360-24V ECO-IR 360-24V Product Features Presence detector with 360° detection range for Automatic control for lighting and HVAC systemsSwitched output for light (potential-free relay) Lighting control with brightness threshold value and self-learning switch off delay timeSwitched output for HVAC (potential-free relay) HVAC control with switch on delay and switch off Self-learning switch off delay for light contactSwitch off delay and brightness threshold infinitely Detection range (Mounting hight 3,0m) Switching Contact «Lighting» The switching behavior is controlled by presence and by daylight. The contact closes in case of darkness and presence, and opens in case of brightness or absence. The minimum switch off delay “2min. - 15 min.” and the desired brightness switching level “Lux” can be adjus- ted. Depending on the occupants’ behavior the module is able to automatically extend the switch off delay to a maximum of 15 minutes or reduce it to the minimum set time. The delay time is re-started on detection of move-ment. The switch-off delay time does not change with a setting of 2min.Important: The ECO-IR is designed for use with fluorescent lights (FL/PL). Incandescent or halo- gen lights disturb the function of the detector. Switching Contact «HVAC» The HVAC control is accomplished by means of a poten- tial-free relay. The switching behavior is controlled only by presence, not by brightness. In case of presence, the contact is closed. The desired switch off delay is infinite- ly variable between 1 and 60 minutes. The delay time is re-started on detection of movement. Interconnection Seated Persons: Parallel Circuit Operation The values given refer to the restricted detection range To cover large or irregularly shaped rooms such as large for movements taking place at table height, i.e. approx. offices, corridors, underground car parks, etc. it is possi-0.80 m above the floor. From a mounting height of ble to connect multiple detectors in parallel. In this case, > 3.5 m the sensitivity of the detector is limited and the overall permitted load does not change. Brightness walking movements are required for detection.threshold and switch-off time delay must be set for each detector individually.Walking Persons: The above figure shows the detection range in side (top) and top (bottom) view. Note that the ranges in which seated persons and walking persons are detected differ in their expansion. Schematic Wiring Diagram – Power Module Location Detection Range The recommended mounting height is 2m - 3.5m. The sensitivity of the detector decreases with increasing mounting height. From a mounting height of 4 m walking movements are required for detection, and the detection ranges of multiple detectors should overlap in their fringe Sensor Module – Rear Side zones. Maximum range approx. 15 m.Accessories Flush mounting A suitable surface frame for surface mounting is also available. Mounting kit Quick-Fix The unit can be flush-mounted into suspended ceilings using the QUICKFIX mounting kit. Important: The voltage supply of the detec- tor must not be interrupted Adjustments on the Sensor Module (see fig. on the left) 1) Switch off delay for HVAC system (minutes) 2) Switch off delay for lighting system (minutes) 3) Brightness threshold (lux) Technical Specifications for Presence Detector ECO-IR 360-24V Sensor module ECO-IR 360A-HR Relay output B „HVAC“ Power module ECO-IR 540Z Relay output „light“ Article numbers *) A load of more than 60V or 100mA on the switching contact This device complies with the protection regulations of the EMC (max. 1.5W) changes its characteristics permanently; the minimum directives 89/3/EWG and of the amending directives 92/31/EEC and load specification of 1V/1mA can no longer be guaranteed.Subject to change without notice.

Erfahrungsbericht – Mumbai, Indien (Marlene Kraatz) Ein Semester an dem Tata Institute of Social Sciences in Mumbai, Indien – Meine Erfahrungen 1. Zur Vorbereitung auf den Auslandsaufenthalt Die Vorbereitungen für meine große Reise nach Indien liefen eigentlich ganz unspektakulär ab. Allerdings sollte man die Dinge, die man erledigen muss, frühzeitig in Angriff nehmen, da
