19.4 Connecting several units in parallel
The outputs (Aî) of several ECO-IR
units can be connected in parallel as shown in Fig. 5.
Important
All of the ECO-IR units connected in parallel must be connected to the same mains phase.
The overall permissible load as a result of the parallel connection is
not
higher.
19.5 Manual OFF circuit
If the automatic function of the lighting system is to be deliberately overridden, a conventional
switch should be connected to the output circuit
downstream
of the ECO-IR (Fig. 4).
19.6 Stepping switch/time switches
The ECO-IR must not be used to trigger stepping switches. The unit may only be connected
in parallel to time switches.
19.7 Connections via external relays
External contactors or relays must be used to connect loads >1.4 kVA to the "Light" output.
Important
Inductive loads must be interference-suppressed with suitable spark extinguishers (e.g. RC
combination)
20 Applications
ECO-IR 180A
for wall mounting
Detection range: 180° (horizontal), 55° (vertical)
(Fig. 6). The recommended mounting height is 2.2 m.
The ECO-IR 180A can also be mounted on the ceiling in corridors. Please note the detection
range or ask for planning documentation.
ECO-IR 360A
for ceiling mounting (e.g. for detecting persons also when seated).
Detection range: 360° (horizontal), 120° (vertical) (Fig. 7). The ideal mounting height is 2 - 3.5
m.
Important
The detection range is reduced accordingly if the ECO-IR 360A is mounted at a lower
position. When mounted higer than 3.5m, larger movements are required and the
detection areas of multiple detectors should overlap at their edges.
In order to ensure that persons are detected correctly, the detection range must not be
impaired by office equipment, partitions, plants etc. (shading).
Note
ECO-IR presence detectors should not be used as alarms.
21 Putting the device into operation
Set the unit as shown on the rear of the disassembled sensor head.
Note the setting guidelines in the following table (see also Fig. 2) for defining the default
settings.
"HVAC" switch-off delay time
•
Set the desired switch-off delay time for the "HVAC" switching contact on the
"Time minutes" potentiometer. The settings are not modified.
The switch-off delay time varies depending on application and load.
10 – 60 min.
