Frequently Asked Questions - TL-ALU9 AREXX

What to do if the TL-ALU9 receiver receives no signal from the sensors?

Check the receiver power supply (adapter or USB). Disconnect power, wait 10 seconds and reconnect. Ensure sensors are within range (20-40 m) and their batteries are charged and correctly installed. Update the firmware via the Temperature Logger software.

How to install batteries in the sensors?

Open the sensor battery compartment. Insert batteries respecting polarity (indicated in the housing). Close the compartment. The sensor should transmit a signal to the receiver within 5 seconds.

Why is a sensor not detected by the receiver?

Possible causes: missing or weak batteries, polarity reversal, sensor out of range or damaged (oxidized contacts). Check batteries and contacts. If the problem persists, move the sensor closer to the receiver and perform a communication test (remove and reinsert batteries).

How to set a temperature alarm on the TL-ALU9?

Connect the TL-ALU9 to the PC via USB. Open the Temperature Logger software and the 'Set TL ALU9 Alarm' tool. Define up to 3 conditions (sensor, high/low threshold, etc.). Click 'Write' to send the rule file to the device.

What to do if the alarm does not sound even though it is triggered?

Check the 'beep' parameter (buzzer duration) in the general settings. Ensure the buzzer is not disabled. If the alarm displays on screen but does not sound, the buzzer may be defective; contact customer service.

How to interpret the graphical display?

In mode C, the graph displays the last 24 data points for a sensor. The horizontal axis represents time (defined by the 'graph step time' parameter), high and low limits are indicated by lines. Use the scroll key to change sensor.

What is the maximum range between sensors and receiver?

The range is 20 to 40 meters indoors depending on materials (walls, metal, glass). To improve reliability, slightly move the sensor or receiver.

How to replace the internal clock battery of the TL-ALU9?

Place a CR2032 battery in the designated slot (accessible by opening the case). The lifespan is about 5 years. After replacement, the clock will be set automatically when connecting to the PC.

Can I use the TL-ALU9 without a PC connection?

Yes, the device operates autonomously: it displays measurements and triggers alarms according to saved rules. USB connection is needed for configuration and data backup.

What to do in case of transmission loss on a sensor?

Check the sensor battery level and absence of interference (other 433 MHz devices, microwaves, metal structures). Move the sensor or receiver. Perform a communication test: remove and reinsert batteries 1 m from the receiver; the sensor should appear in the list within 5 seconds.

2. INTRODUCTION TL-ALU9 ALARM UNIT

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 transmitting 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.

3. TL-ALU9 OPERATIONS

1. Display mode button
2. Scroll button
3. Power-on indicator
4. Display
5. On - off switch

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: identification 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 first line the sensor id and time of the alarm 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 sensor. 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.

Mode D shows the model and firmware version, the actual date and time, and the actual general setting-values. The setting-values can be changed by the TL-ALU9 configuration tool.

general setting-values:

graph: the time between 2 data points in seconds. There are 24 data points shown per graph. This value defines 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 unconfirmed.

4. Set alarms

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-file that defines one or more rules that can trigger an alarm. The rule file has the same format as the rule file for the BS1000. Therefore there are several ways to define rules for the TL-ALU9.

The easiest way is to use the TL-ALU9 configuration tool see tools menu in the logger software.

Screen 1: Alarm configuration

This tool can be found in the tools menu of the temperature logger software. The tool is also used to read an set the general settings.

SET TL ALU9 ALARM

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

Screen2: TL ALU9 General configuration

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 ^1 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 unconfirmed.

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 defines the total time-span of the graph.

(1) Coordinated worldtime, also UTC (Universal Time Coordinated), this is the official 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 register 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 firmware.

Please check the internal TL9-ALU clock battery (Type CR2032)

The lifetime of the TL9-ALU battery is about 5 years!

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.

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.
