Sensor Connection
This section covers connection procedures of the TKLS fuel level sensor:
• Power supply connection
• RS-485 bus connection
• Frequency output connection
The sensor is supplied with a 7.5m signal cable in a corrugated pipe. The cable is equipped
with a female connector (Connector 2) for connecting to the sensor (to Connector 1). Both
connectors are keyed, which prevents incorrect orientation.
When making connections, pay careful attention to the safety rules stipulated by the
regulations for motor vehicle repair procedures. All connections should be properly isolated
and securely connected. If the wire is too short, it can be spliced with a wire of at least 0.5
mm2 cross section (20 AWG or thicker).
The TKLS sensor can be connected to any external unit that supports ModBus or LLS
protocols to transfer fuel level readings.
The TKLS sensor is equipped with a frequency output that provides transfer of fuel level
values in the form of pulses at a variable frequency. The sensor is also capable of measuring
ambient temperature.
IMPORTANT
All connections should be performed when the sensor and all external devices be connected to the sensor
are disconnected from the power supply.
