»NOTES ON DISPOSAL

As a component of a large-scale fixed installation, Thermokon products are intended to be used permanently as part of a building

or a structure at a pre-defined and dedicated location, hence the Waste Electrical and Electronic Act (WEEE) is not applicable.

However, most of the products may contain valuable materials that should be recycled and not disposed of as domestic waste.

Please note the relevant regulations for local disposal.

»BUILD-UP OF SELF-HEATING BY ELECTRICAL DISSIPATIVE POWER

Temperature sensors with electronic components always have a dissipative power, which affects the temperature measurement of the ambient

air. The dissipation in active temperature sensors shows a linear increase with rising operating voltage. This dissipative power has to be considered

when measuring temperature. In case of a fixed operating voltage (±0,2 V) this is normally done by adding or reducing a constant offset value. As

Thermokon transducers work with a variable operating voltage, only one operating voltage can be taken into consideration, for reasons of

production engineering. Transducers 0..10 V / 4..20 mA have a standard setting at an operating voltage of 24 V =. That means, that at this voltage,

the expected measuring error of the output signal will be the least. For other operating voltages, the offset error will be increased by a changing

power loss of the sensor electronics.

»GUIDELINES FOR DEVICES WITH SOLAR ENERGY STORAGE

Due to the energy-optimized EnOcean radio technology used in ”EasySens®“ wireless sensors, the devices can work without batteries and self-

charge themselves using electric energy generated by integrated solar cells. This makes the devices almost maintenance free and environmentally

sound due to not having to replace batteries.

For optimum use, the device should be mounted in a location with sufficient ambient brightness. Minimum illumination of 200 lx (artificial light or

ambient) is required for at least 3 to 4 hours each day. (The health and safety regulations at work require a minimum illumination of 500 lx for office

workplaces).

The solar cell should be mounted facing towards the window direction if possible. If the device has a temperature sensor, then even periodic direct

sun radiation should be avoided due to incorrect false temperature readings.

The mounting position should be selected so that the device will not be obstructed in the future: for example by placement areas, additional furniture

or roll-fronted cupboards.

The sensor is supplied in an operational state. If the sensor has been stored in darkness for longer periods, the internal solar energy storage will

most likely need to be recharged. This would normally happen automatically during commissioning or during initial start up in ambient light. If the

initial charge is not sufficient, the sensor will reach its full operating state up to 3 to 4 days, if the requirements for minimum illumination per day

are met. The sensor will then transmit continuously in darkness as specified f (2/3 days on factory default telegram timing). Depending on the

application it is also possible for the devices to operate in darker rooms (with brightness <100 lx) by using the battery back-up option. Batteries to

be used are listed in accessories.

The operating time when using batteries will depend on the transmission frequency as well as the component aging and the self-discharge of the

battery. Standard operating time will be 5-10 years on factory default telegram timing. Changing of the device from solar to battery operation is

done automatically by simply adding a battery to the device.

»COMMISSIONING AND TRANSMISSION TIME INTERVAL SETTING

To ensure that the measured values of the sensors are correctly evaluated at the receiver, it is necessary to teach the devices into the receiver.

This is done automatically using the "Learn" button on the sensor or manually by entering the 32bit sensor ID and a special "teach-in procedure"

between transmitter and receiver. Details are described in the respective software documentation of the receiver.

To access the Learn button, turn the sensor cover counterclockwise

and remove the cover.

The learn button is located on the bottom of the motion sensor. The

exact positioning is shown in the figure on the right.

Setting of transmission time

Before opening the device, disconnect it from the power supply!

Factory default: T_wake up: 100, T_intervall: 10

Transmission time = 100 seconds (T_wake up) x 10 (T_intervall)

= 1000 seconds = approx.16 minutes

Note fort he battery operated device: The transmission frequency

also has a direct influence on the operating energy available in the

energy storage device and thus on the discharge time of the energy

storage device during operation.

»MOUNTING ADVICES

Mountiung hight

The mounting height has a direct influence on the range of the motion detector. The optimum mounting height is 8.9 ft. (2,7 m). All other

dimensions will change the range.

Fixed mounting

The motion detector must be mounted on a solid surface, as any movement of the detector will result in false alarms.

Distance to switched luminaires

In order to avoid unintentional switching on of the luminaire by the motion detector, the luminaire should not be mounted in the detection area of

the motion detector. Also avoid mounting the motion detector above a luminaire. The heat radiation of the luminaire can influence the function of

the motion detector and possibly lead to a false triggering of the detector.

Mounting sideways to the walking direction

For optimum motion detection, the detector must be mounted to the side of the detection area so that the zones are cut as vertically as possible.

Mounting locations where the objects to be detected move directly onto the motion detector result in a significant reduction of the range.

Distance to interference sources

To avoid false alarms, sources of interference such as radiators, lamps, air outlets from air conditioning systems, etc. should be outside the

detection range. Direct sunlight should also be avoided.

Feedback on detected movement

Motion detection by the sensor is signalled by the integrated signal LED (flashing for approx. 2 seconds). Note: The signalling LED is independent

of the set follow-up time of the relay output. During initialisation of the device (voltage reset), the signalling LED and the relay output are switched

on for approx. 45 seconds.
