Transport and Storage
The device is sensitive to mechanical damages. Care should be taken to properly protect the device during
transport to eliminate any damage. It is forbidden to transport the device components separately in a
collective package – each component must be packed separately and cannot 'bump' during
transportation.
Due to protective packaging, the device should be stored in the temperature -25°C ÷ +60°C [-
13°F ÷ 140°F] at the humidity below 99%RH.

Mounting
The roof functions as a mounting bracket (Fig. 3).
Fig. 3
NOTICE!
It is forbidden to make any additional mounting points or any holes in the device assembly
components.

Page | 5
Alternative mounting options
The roof construction allows you to mount the signalling device on posts with diameters of
50÷70mm [2÷2.8in] and 100÷120mm [3.9÷4.7in], using a U-bolt with a rod diameter of 8mm
[0.7in] (Fig. 4), or on the BT-470 scale display visor (Fig. 5).

TL-280 Configuration
The configuration of the device using the menu allows:
1 Choice of a communication protocol with a control module, such as a weighing terminal,
an operator panel
2 Determining the response to the events reported by the control module
Embedded user menu ("DEF" microbutton)
The user menu embedded in the device allows you to select a communication protocol, display
the information about the software version, display the set protocol, reset to the default settings.
The DEF microbutton, used to operate the menu, is located inside the signalling device.
However, after unscrewing the lock screw it is accessible through the technological hole without
opening the device.
det. A - lock screw; det. B - technological hole
Fig. 6
The user menu is called up by pressing and holding down the "DEF" microbutton and releasing
it when the desired option is displayed. Regardless the option, you can exit the user menu by
pressing the microbutton and releasing it when switching between the options (while switching
between the options, the display is not displaying any information).

Page | 7
The user menu has the following options:
1) i (info) - This option allows you to display the software version and returns the information about
the set communication protocol. Exiting the info option is done automatically after displaying
the information.
2) P (proto) - This option allows you to select a signalling device communication protocol to work
with the given control modules uploaded to the device memory. You can change a protocol by
pressing the microbutton. Accepting the selected protocol is accomplished by long holding
down the microbutton (until the inscription "Ok" appears). Exiting the "proto" option comes
after 30 seconds of the user inactivity.
3) C (custom) - The "custom" option allows you to select a dedicated signalling device
communication protocol to work with the control modules of selected clients. The protocols have
special, custom settings needed for a given customer. Setting a protocol is done in the same way
as in the case of the "proto" option - accepting the selected protocol is accomplished by long
holding down the microbutton (until the inscription "Ok" appears), while exiting the "custom"
option comes automatically after 30 seconds of the user inactivity.
4) R (reset) - This option allows you to reset the default light signalling device protocol. In
addition, in the devices with the Ethernet interface, you can restore the default network layer
settings (IP address: 192.168.0.11, network mask: 255.255.255.0, and the communication port
for the control module). To restore the default settings you should, during the normal
operation of the device, press the microbutton and hold it down until the inscription "R"
appears. Hold the button down until the inscription "R" starts flashing and do not release it
until the information "default" is displayed. Releasing the button before the inscription
"default" appears will result in interrupting the process of restoring the default settings and
the display will continue working according to the previously accepted parameters.

Standard Protocols – Data Frame
The data frame consists of three bytes. The detailed construction is shown in Table 3.1.
The construction of the standard protocol frame.
Byte
no.
Value [hex] Description
0
0x3A
Frame start byte (‘:’)
1 0x00 – 0x7F Red light byte. Value 0x52 ‘R’ turns on the red light. Sending a different
value will result in displaying a character from the ASCII table.
2 0x00 – 0x7F Green light byte. Value 0x47 ‘G’ turns on the green light. Sending a
different value will result in displaying a character from the ASCII table.
Examples of frames:
„0x3A 0x52 0x20” – on the signalling device the red light will be turned on, the green light will be
turned off.
„0x3A 0x20 0x47” – on the signalling device the green light will be turned on, the red light will be
turned off.
„0x3A 0x3C 0x3E” – on the signalling device the red symbol of the left arrow and the green
symbol of the right arrow will be turned on.
„0x3A 0x20 0x5E” – on the signalling device the red symbol turns off and the green symbol of
the up arrow will be turned on.
Alpha characters and symbols will be displayed within the signal
area. Combinations of characters can be sent to assist color blind
individuals.

Automatic brightness control of the light
signalling device
In the standard version, the controller has a lighting sensor included, which is placed on the
LED panel. The device, in response to the ambient brightness, adjusts the light signalling device
brightness.
Initial start-up
Step 1: Make sure that all cables are properly connected,
Step 2: Make sure that all components have been installed in correct orientation,
Step 3 Connect the device to the mains power supply,
Step 4 The properly connected system will display the symbols "-" in the light fields, followed by
the hard space symbol ( _ ) in the bottom field . It means that the device is working according to
the default protocol. In 7 seconds, the signalling device will go into the default display state.
Changing Ethernet Settings
Wagset Software can be used to change the IP address. The TL-280 does not support a web
application like the BT-480.
WagSet 2: WagSet 2 Software Download
Open Wagset, click “Create own Protocol”, Select File, then “display network settings”
Change IP address under “New Display Settings”, then click Send.

Additional options
Operator panel Item# 841-500083
The operator panel is a separately offered accessory (additional option) which, among others,
can work with the device. On the panel, there are two monostable buttons that allow you to
change the information displayed by the signalling device. An example of the panel is shown in
