PD4-M-HCL 93006/93007

1. Operation

1.1. General

The PD4-M-HCL is a highly sensitive ceiling-mounted occupancy
detector based on passive infrared motion detection, with
integrated DALI controller, DALI power supply and push button
control.
If people, animals or other heat sources move within the
detection area, the detector can dim and switch any DALI-
controlled electronic ballast-driven lights, taking account of
ambient light levels, such that a predefined room lighting level is
constantly maintained. Slave devices, type PD4-S-DAA4G, can be
installed to expand the detection area.

1.2. Human Centric Lighting

Human Centric Lighting (HCL) automatically changes the colour
temperature and brightness of compatible DALI luminaires (DALI
Device Type 8) during the day. This change takes place slowly and
imperceptibly in small steps. The lighting is based on natural
daylight, which has a positive effect on well-being, performance
and the natural sleep rhythm.

1.2.1. HCL Mode

Three modes can be selected under "HCL Mode":
•
In "Application Profiles" mode, brightness and light
temperature are automatically changed during the day
based on a defined curve. The selection of the profile
suitable for the application is made in the next point.
•
In "outdoor light sensor" mode, the light temperature of the
luminaires follows the light temperature outdoors. For this
purpose an external light sensor from B.E.G. - which is to be
ordered separately - is required. The brightness can be freely
selected.
•
In "Demonstration Mode", the light temperature changes
step by step from warm to cold white. This function is used
for test or presentation purposes.

1.2.2. Application profiles

All profiles are designed to activate from morning to afternoon
with increasing brightness and colour temperature. During
lunchtime and from late afternoon, the activating effect is
reduced. The lighting goes into the warm white area and to the
lower light level. Overnight, the lighting remains at this setting.
The "Application profiles" are optimised for special use. Under
"Application profiles" you can choose between three profiles:
•
In the "Office" profile, the brightness during the day is
controlled from approx. 500 to 650 lux and the colour
temperature from approx. 3500 to 5500 Kelvin.
•
In the "Industry" profile, the brightness during the day is
controlled from approx. 500 to 750 lux and the colour
temperature from approx. 3500 to 5500 Kelvin.

•
In the "School" profile, the daytime brightness is controlled
from approx. 350 to 500 lux and the colour temperature
from approx. 3500 to 5500 Kelvin.

1.2.3. Date

The current date must be transferred from the smartphone to
the detector via the app. The integrated real-time clock can then
control the application profiles. In the event of a power failure,
the real-time clock is powered by an internal battery for at least
48 hours.

1.2.4. Time

The current time must be transferred from the smartphone to
the detector via the app. The integrated real-time clock can then
control the application profiles. In the event of a power failure,
the real-time clock is powered by an internal battery for at least
48 hours.

1.3. Groups and lighting zones

There are three lighting zones (areas for a lighting purpose)
available which can be parameterised by means of a predefined
grouping principle of the integrated DALI control unit and an
operating mode of the integrated relay.
