HELVAR 314 Tilting User manual

The Tilting Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.
The unit can also be controlled using a Helvar infrared remote handset, such as the 303 DIGIDIM Infrared Remote Control.
Helvar’s 314 detects movement using its highly sensitive microwave detector. It works by emitting low-power microwave signals
and measuring the reflections as the signals bounce off moving objects.
The unit has an adjustable sensor head that allows the area of detection to be optimised for the required application.
When an area is no longer occupied, the load switches off after a certain time. This time-out period is configured using Helvar’s
lighting system design and control software: Designer, or Toolbox.
314 Tilting Microwave Detector Installation Guide
Features and Connections
Microwave sensor: Detects movement within the detection range allowing
load control in response to changes in room occupancy.
IR Receiver: Receives control and programming commands from a
Helvar infrared remote handset (available separately).
Status LED: The red LED flashes to indicate the following:

Valid setting received x1
Identify active x6
The DALI connection is made via
DA+ and DA– terminals.
The DALI input is not polarity
sensitive unless you are using an
external power supply.
Optional connection to external power, 12 V to 24 V.
See ‘External Power Supply (Optional)’ on
page 2.

• Position the detector so that the occupants of the room are normally inside the detection zone.
• Do not install the detector within 1 m of any lighting, forced air heating, or ventilation equipment.
• Do not fix the detector to an unstable or vibrating surface.
• Install the unit as far away as possible from the surface of metal objects.
• The detection pattern illustrated (see ‘Detection Pattern’ on page 1) is based on a mounting height of 2.8 m. A lower
mounting height will decrease the overall size of the detection zone.
Prerequisites
Installation
Connection, Fitting and Set Up
Connect the DALI
terminal blocks.
If required, connect the
external power cable.
External Power Supply (Optional)
The table below shows the various 12 V to 24 V external
power supply units that can be used and the sensor
hardware revision needed for each of them.

With some models, you must make a wire
link between the DALI negative terminal
and the negative terminal of the external
power supply, as shown in the figure.

Attach the cable clamp. Insert the detector into the
cutout. Take special care when
bending the springs back
3. Ø 78 mm
Ensure the fitted unit sits flush
to the ceiling.

With the circuit switched on the
LED in the sensor will flash red
for 30 seconds.
When the detector is activated the relating light load will
illuminate and remain on for a defaulted time of 20 minutes if
there is no other movement detected.
Check the DALI network connection by selecting the Identify function
in Designer or Toolbox
Adjustments to the detector such as sensitivity, On / Off transitions
and illumination periods can be managed using Designer or Toolbox.
Note: Maximum sensitivity makes the detector unit extremely sensitive
to movement and may detect through glass, thin walls or partitions. If this
causes a problem, reduce the sensitivity.
When using Designer, connect the PC to the lighting network via a
Helvar router.
When using Toolbox, connect the PC to the lighting network via a
Helvar serial or USB interface.
