Normal use This product was developed as an alarm module for the AREXX Multilogger system. It will only work together with other AREXX Multilogger sensors and products. W ith the TL-ALU9 wireless alarm unit you can generate an alarm when a sensor reaches the alarm setting. The TL-ALU9 can be simply programmed with a PC. The Alarm setting can be a temperature or voltage but also the state of a switch. It may be used indoors only. The product must not get damped or wet. Also be careful with condense when you take it from a cold to an warm room, give it time to adapt to the new conditions before you use it. Any use other than that described above can lead to damage to the product and may involve additional risks such as short circuits, re, electrical shock etc. Please read all the safety instructions of this manual.

Starting up - Please read this manual rst. - Connect the power adapter and switch on the TL-ALU9 - Check the display if it receives sensor data - Connect the TL-ALU9 receiver to the computer and start the logger software alarm tool to program the alarm unit. - Consult the help function of the software if you have further questions. Important information about the Alarm Unit - The Alarm Unit receives the measurements from the sensors wirelessly. - Several sensor types are available, like temperature, relative humidity, CO2 levels etc. - Many temperature sensors can be connected to the system at the same time. - Separate sensors for the multilogger are available at your dealer. - We have connected 60 sensors to one single receiver without any problems. - The Alarm unit graphically shows the sensor measurements of a longer period of time. - ATTENTION: Most of the sensors are not waterproof! - The range of the sensors can vary as a result of environmental inuences. Depending on the material properties of the surrounding areas, sensors located inside refrigerator systems may not be able to communicate with the receiver.

The alarm unit registers for each sensor the measurement together with the date and time stamp. With the TL-ALU9 wireless alarm unit you can generate an alarm when a sensor reaches the alarm setting. The TL-ALU9 can be simply programmed with a PC. The Alarm setting can be a temperature or voltage but also the state of a switch. When the alarm setting is triggered it will give for an period an Acoustical alarm and continues a light alarm until the alarm is reset. The TL-ALU9 displays all sensor data, which have been transferred by temperature sensors. It is also possible to show the sensor data in a small graph on this display. the AREXX multilogger sensors continuously register and report new values to the receiver at intervals of ca. 45 seconds. Sensors and receiver use a wireless communication system, working at 433MHz. This frequency is freely available for communication at transmit- ting powers under 10 milliwatts. Depending on surrounding building constructions, the allowed 10mW power level allows a transmission range of 20-40 meters. Temperature sensors may be located inside or outside buildings, at any place where an overview of temperature curves is desired. Unreliable signal levels may be improved substantially by slightly modifying the sensor’s or the receiver’s location.

By pressing the display-mode button (1) different display modes can be selected: A- List of incoming measurements B- Recent generated alarms C- Graphical display of recent measurements D- General settings The scroll button (2) is used to scroll through the data. Mode A displays the measurement data per line: - rssi indicator: This indicates the received signal strength of the rf data signal - sensor id: identication number of the sensor. - time (hh:mm:ss) - measurement value - measurement unit, dependent on the actual sensor. Mode B displays the alarm report. On the rst line the sensor id and time of thealarm are given, together with the measurement value and unit. The following lines are used to display the accompanying text of the rule. Mode C displays the recent measurements in graphical form per sen- sor. There will be presented a graph for each sensor, accessible by the scroll button. The graph shows the upper and lower boundary, the sensor id and unit. Also a simple timescale is shown. The range of the graph is set in the general setting section.

H20 ModeDshowsthemodelandrmwareversion,theactualdateand time,andtheactualgeneralsetting-values.The setting-values can be changed by the TL-ALU9 conguration tool. general setting-values: graph: the time between 2 data points in seconds. There are 24 data points shown per graph. This value denes the total time-span of the graph. beep: duration of the buzzer in seconds. The buzzer will turn on when an alarm is set, and turn off when the user presses button (1) or (2), or when the buzzer is active for more than this duration. scrn: display time-out in seconds. When no button Is pressed, the display will turn off after this period of time. By pressing a button, the screen will turn on again. rpt: repeat alarm time in seconds. The alarm is repeated after this period of time when the alarm was left unconrmed.

The alarms can be set by a pc program. In order to do so, the unit should be connected to the PC via the usb cable. The TL-ALU9 uses a so called rule-le that denes one or more rules that can trigger an alarm. The rule le has the same format as the rule le for the BS1000. Therefore there are several ways to dene rules for the TL-ALU9. The easiest way is to use the TL-ALU9 conguration tool see tools menu in the logger software.

Screen1:Alarmconguration This tool can be found in the tools menu of the temperature logger soft- ware. The tool is also used to read an set the general settings.

This tab can be used to dene a simple set of rules that will control the alarm generation of the TL-ALU9. On this screen up to 3 conditions can be specied. Each of the condition given will trigger an alarm when such a condition is met. When lled in, push the write button, and the rule-le will be submitted to the alarm unit. Also, the current rule-le can be read by pressing the read button.

H22 Screen2:TLALU9Generalconguration The general settings of the unit can be inspected and changed by this screen. With the ‘read’ button the current settings are read, and with the ‘write’ button the given parameters are stored in the unit. The following parameters can be set: Clock offset: The internal clock is set by the pc to UTC

time. To convert the displayed time to local time this offset is used. Alarm repeat time („rpt“): repeat alarm time. The alarm is repeated after this period of time when the alarm was left unconrmed. Duration of alarm signal („beep“): duration of the buzzer. The buzzer will turn on when an alarm is set, and turn off when the user presses button (1) or (2), or when the buzzer is active for more than this duration. Screensaver time (scrn): display time-out. When no button is pressed, the display will turn off after this period of time. By pressing a button the TL-ALU9, the screen will turn on again. Graph step time („graph“): the time between 2 data points in seconds. There are 24 data points shown per graph. This value denes the total time-span of the graph. (1) Coordinated worldtime, also UTC (Universal Time Coordinated), this is the ofcial standard worldtime.

5. Transmission losses

Sometimes transmission losses may arise, indicated by missing temperature data in the sensor’s curve display. Data losses may be caused by:

1. Problems with the TL-ALU9 alarm receiver

2. Problems in the temperature sensor module

3. Problems in the signal transfer between temperature sensor

module and Alarm receiver 5.1. Problems inside the TL-ALU9 receiver The receiver does not registrate a single data signal, even if the sensor is located at a minimum distance to the receiver. Potential problems: - Receiver is not in the range of the sensors - The TL-ALU9 receiver has no power - Unknown TL-ALU9 problem. Suggested solutions: - Check the Power - Remove the Power adapter connector, wait about ten seconds and reconnect the cable again. - Install the latest TL-ALU9 rmware.

Please check the internal TL9-ALU clock baery (Type CR2032) The lifeme of the TL9-ALU baery is about 5 years!

H24 5.2. Problems in the temperature sensor module The receiver receives signals from sensors, but fails to register signals from one sensor in particular. Potential problems: - Sensor batteries are missing or are at a low charging level - Reversed polarity of the sensor’s batteries - The sensor’s location is outside of the receiver’s reception range - Damage to the sensor (by corroded battery contacts, moisture or battery leakage) - Problems in the radio signal communication Suggested solutions: - Insert fully charged batteries in the sensor and repeat the communication test (please check the polarization of the batteries before inserting!!) - Check the battery contacts and remove all corrosion and moisture effects.

H25 5.3. Radio signal transfer problems The receiver system is missing signals from one or more sensors, or only receiving a limited number of signals. Potential problems: - Walls or ceilings between sensor and receiver may contain metallic constructions. - Sensors and/or receiver may is located on or by a metallic surface - Sensors and/or receiver are situated in locations with high humidity - Windows between sensor and receiver may contain several layers of shielding materials or may be covered by humid moisture. - Other 433MHz systems may be working within the 20m operating range - Interference or jamming signals from radio or TV transmitters - Electronic or electrical equipment (eg. computer equipment or magnetrons), operating within the 2-5m operating range - Low power level of the sensor’s batteries (see 2) Suggested solutions: - Modify the locations of the sensor and/or the receiver - Remove the interfering equipment

5.3.2. Communication test

A simple test will check the communication channel between sensor and receiver:

1. Remove the batteries from the sensor

2. Locate the sensor at ca. 1 m distance to the receiver

3. Insert the batteries in the sensor

4. A correctly working system will show the according sensor entry

to the sensor list within 5 seconds. Extra information and possible updates can be found on www.arexx.com (on the forum or through the Temp Logger menu). Further questions can also be put on our forum; www.arexx.com
