Sewi KNX L

Indoor brightness sensor

Technical specifications and installation instructions

Item numbers 70395 (white), 70695 (jet black)

Description

The Sensor Sewi KNX L for the KNX bus system captures the brightness in the

room. The measurement value can be used for the control of limit-dependent swit-

ching outputs. States can be linked via AND logic gates and OR logic gates. Multi-

function modules change input data as required by means of calculations, querying

a condition, or converting the data point type.

Functions:

•

Brightness measurement with brightness control

•

Threshold values can be adjusted per parameter or via communication

objects

•

8 AND and 8 OR logic gates, each with 4 inputs. All switching events as

well as 16 logic inputs in the form of communications objects can be used as

inputs for the logic gates. The output of each gate can be configured

optionally as 1-bit or 2 x 8-bit

•

8 multi-function modules (computers) for changing the input data by

calculations, by querying a condition or by converting the data point type

Configuration is made using the KNX software ETS. The product file can be dow-

nloaded from the Elsner Elektronik website on www.elsner-elektronik.de in the

"Service" menu.

Safety and use instructions

2.1. General installation notes

Installation, testing, operational start-up and troubleshooting should

only be performed by an electrician.

CAUTION!

Live voltage!

There are unprotected live components inside the device.

•

When planning and installing electrical systems, observe the

applicable directives, regulations and provisions of the

respective country.

•

Ensure that the device or system can be disconnected. During

installation, disconnect all cables from the power supply and

take safety precautions against unintentional switch-on.

•

Do not use the device if it is damaged.

•

Take the device or system out of service and secure it against

unintentional use, if it can be assumed, that risk-free operation is

no longer guaranteed.

The device is only to be used for the intended purpose described in this manual. Any

improper modification or failure to follow the operating instructions voids any and

all warranty and guarantee claims.

After unpacking the device, check it immediately for possible mechanical damage.

If it has been damaged in transport, inform the supplier immediately.

The device may only be used as a fixed-site installation; that means only when as-

sembled and after conclusion of all installation and operational start-up tasks and

only in the surroundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may

occur after publication of these operating instructions.

Installation

3.1. Installation location and preparation

Install and use only in dry interior rooms! Avoid condensation.

The Sensor Sewi KNX L is installed surface mounted on walls or ceilings.

3.2. Connection

For installation and wiring at the KNX connection, the

provisions and standards applicable to SELV circuits must be

complied with!

The Sensor Sewi KNX L is surface-mounted but at the same time can also be scre-

wed to a flush-mounted socket.

If the Sensor Sewi KNX L is installed on a flush-mounted socket, it must not con-

tain any wiring with 230 V.
