HELVAR 317M Installation Manual

Installation Guide High-Bay PIR Presence/Absence Detector (317M)
The 317M High-Bay PIR Presence/Absence Detector, in conjunction with a Helvar lighting control system, provides automatic control of
lighting loads in buildings and interior spaces with high ceilings. The 317M is typically installed in warehouses and factories, and is used
in other applications where mounting heights are too high for standard sensors.
The 317M is compatible with Helvar's lighting systems and configuration software, Designer and Toolbox. Once connected to a Helvar
DALI network and lighting control system, the software automatically detects the unit, which can then be programmed with the required
functions.
Features and Connections

Sensor lens
- PIR Sensor
- Status LED
- IR Receiver
PIR Sensor - Detects movement within the detection range, allowing load control in response to changes in room occupancy.
Status LED - The red LED flashes to indicate:
Valid setting received (single flash of LED)
•
Identify active (LED flashes repeatedly)
•
DALI Connection -
The DALI connection is made via DA+ and DA– terminals. The device is not polarity-sensitive.
Sensitivity, Time-Outs, Identify
Adjust the sensitivity using Designer or Toolbox. The factory default setting is 9 (maximum).
Note: On maximum sensitivity, the detector unit is extremely sensitive to movement and may detect through glass, thin walls or partitions. If
this causes a problem, reduce its sensitivity.
The temperature difference between the detection target and the background must be at least 4 °C.
Adjusting On, Exit and Transition Time-Outs
The default time-outs for On, Exit and Transition can be altered using Designer, or Toolbox.
To make sure that the sensor is correctly connected to the DALI network, use the Identify function in Designer or Toolbox. The sensor's
status LED flashes repeatedly until Identify is cancelled.
