Analogue sensor module

Description

Three external analogue sensors are connected to the Niko Home Control installation using the analogue sensor module.
The sensors must be suitable for use in applications with a safety extra-low voltage (SELV).
This type of sensor is used for measuring sunlight, wind, rain, CO2, humidity or temperature. In function of the values
measured, applications such as sun blinds, roller shutters, and lights can be operated automatically.

Overview

Operation

When a connected sensor is activated, the corresponding input will receive a signal between 0 and 10 V and the module
will forward this value and the address to the controller, which then activates one or several pre-programmed actions. Each
value corresponding to a certain input voltage is set via the programming software.

Activation of a connected sensor can be simulated by pressing the button. The real input will in that case be deactivated
for two minutes.

Installation

Wiring diagram

Follow the steps below to install the module:

• Ensure that the installation is disconnected from the mains.
• The distance between the sensors and the module should not exceed 100 m.
• A maximum of three sensors can be connected per module. Up to 10 modules can be connected per installation.
• Always use sensors that are suitable for applications with a safety extra-low voltage (SELV).
  • If the sensor uses an SELV (24Vdc) power supply, then it is always suitable.
  • If the sensor uses a 230 Vac power supply, then it must have a galvanically isolated output (SELV).

1. Press the module onto the DIN rail until it clicks into place. Position the module preferably in the top row inside the electrical cabinet to keep the SELV cables separate from the 230V cables.
2. Connect the sensors to one of the screw terminals 1-3.
3. Connect the mass of the sensors to the common screw terminal COM.
4. Connect the analogue sensor module to the module before it. Slide the sliding contact of this module to the right until it clicks into the analogue sensor module. This will ensure that the bus and the power supply voltage are connected.

Error codes

When the module is functioning properly, the STATUS LED will light up in TEST mode only. The table below provides an overview of all error codes.
