Frequency Output Connection
TKLS sensor is equipped with one frequency output, which is open-collector. The frequency
of the output signal is proportional to the fuel level in the tank.
The output frequency range varies from 100 Hz to 3000 Hz.
Maximum load current should not exceed 200 mA.

IMPORTANT
When connection to the AutoGRAPH controller, the sensor must be connected to one of the active low
digital inputs of the controller (inputs 1-4).
The frequency output is intended for connection:
• to the digital input of the AutoGRAPH on-board vehicle tracking device, which can acquire
the reading in frequency form;
• to digital input of a third-party device supporting frequency measuring within the range of
frequency signal provided by TKLS sensor.
When connection to the AutoGRAPH controller, the sensor must be connected to one of the
active low digital inputs of the controller (inputs 1-4).Before connecting to the TKLS-L, the
input of the AutoGRAPH must be switched to Frequency Mode.
The configuration of third-party device must be performed according to the instructions given
in the User Manual of that device.
