Safe Operation and Installation

This section contains important information for effective and safe operation of TKLS fuel level

sensors. Please read the information below before using the sensor.

• Sensors with damaged insulation of conductive parts, testing probe and body must not

be used.

• Operational conditions of the TKLS such as electrical and environmental characteristics

and condition of measured liquid should t the requirements contained in this User Manual.

Otherwise, the manufacturer will not be responsible for sensor safety and functional

efciency.

• All connections should be made when the sensor and external devices to be connected to

the sensor are disconnected from the power supply.

TKLS • USER MANUAL

This User Manual applies to the TKLS fuel level sensor (hereafter – TKLS, sensor) produced

by TechnoKom Ltd. It contains installation and connection procedures of the TKLS, as well as

its function and control.

This Manual is intended for specialists who are aware of the maintenance and installation

principles typical for motor vehicles and are procient in using the electronic and electrical

equipment of various vehicles.

To ensure the best performance of the TKLS, it should be installed and set up only by qualied

specialists.

The TKLS sensor can operate both as a part of a fuel monitoring system and as a part of a

eet management system. For proper operation of the TKLS sensor, the customer should be

aware of the operating principles of these systems as a whole, as well as understanding the

functions of its individual components

Product Overview

The TKLS fuel level sensor is designed to measure fuel level in a vehicle fuel tank and transfer

this information to external devices via one of the supported interfaces. The TKLS can be

used as a replacement of the factory-tted standard fuel level sensor or as an additional

sensor for fuel level monitoring.

The TKLS supports data transfer via RS-485 bus, in AGHIP, LLS and Modbus protocols, and

via frequency output as pulses proportional to measured fuel level, PWM signal or periodic

sequence.

In addition to fuel level, the sensor measures ambient temperature and sends the readings

to an external device.

Any device equipped with RS-485 which supports data exchange in AGHIP, LLS or Modbus

protocols can operate as an external device (for example, a level indicator or a eet

management device).

TKLS fuel level sensors support AGHIP protocol which is communication protocol between

AutoGRAPH hardware which enables transmission of additional data, as well as readings of

the sensor built-in inclinometer.

Also connected to AutoGRAPH eet management system, TKLS-L sensor is able to load a

new rmware and new conguration from remote server via GPRS.

Technical Specification

TKLS • USER MANUAL 7

1The AGHIP protocol is the AutoGRAPH Hardware Interface Protocol used by AutoGRAPH onboard controllers to communicate with TKLS sensors and

providing exchange of additional information, e.g. inclinometer readings, error reports and etc. In order to establish the communication between the

AutoGRAPH controller and the TKLS sensor in AGHIP protocol, it is sucient to enable the protocol in the controller as it is enabled in theTKLS by default and

does not require any sensor re-conguration. It means that if the device, which theTKLS is connected to, initiates the communication in the AGHIP protocol,

the sensor will automatically recognize it even if other protocol is enabled in the sensor.

2The function is available only for AGHIP and LLS protocols. When theTKLS is connected to the AutoGRAPH on-board controller, the“Wide record”option

should be enabled in the controller’s settings in order the controller to be able to read temperature readings.
