Operation with other combustible or explosive liquids or water and hydrous liquids is not admissible! The VOTRONIC Tank Sensor Diesel has been particularly designed for tank control of auxiliary tanks, extension tanks and special tanks in intervention vehicles, high-quality campers, as well as in the marine field. It allows exact electric remote measurement of the tank levels. Suitable for Plastic and Metal Tanks Free installation, even subsequently, at the upper side of the tank No mechanically moved parts, fully electronic capacitive measuring method Linear, continuous signal of the level The electronic system is sealed waterproof and vibration-proof Independent of pressure, no falsification of measured values in case of pressure filling etc. Protection against reverse battery, overvoltage, short-circuit and overload Safety through internal test procedures being executed continuously.

Installation at the Tank: --2-- The sensor is designed for vertical installation viewed from the tank top. The sensor should be placed at the topmost location and in the tank centre. Use a conventional circular cutter to drill a hole of a diameter of 63 ± 0.5 mm at this location. Adaptation of the probe to the existing tank height: Shorten the probe with a commercially available metal cutting saw to the required length. The exterior protective tube as well as the inside electrode are separated at the same height. Eventually produced chips or burrs must be removed carefully (sharp blade or the like)! It is important that a clearance of at least 10-20 mm is left between tank bottom and probe (formation of sludge, condensate water, tank movement during driving etc.)!
--3-- Connection Tank Sensor Diesel 010 (Voltage Output Three-wire Conductor): After the installation at the tank, the sensor is connected to the tank display and the power supply (battery+, fused!) according to the following drawing. Load resistor (burden) at the signal output: From minimum 1,000 Ohms to max. infinite. a. Tank Display with Voltage Input 0-10 V (Rotary Encoder to Output 0-10 V): b. VOTRONIC Tank Displays (Set Rotary Encoder to Output 0-2.3 V ): The connections to the VOTRONIC Tank Displays are marked with the figures 1, 4 and 5, and their assignment is the following: 1 = black Battery 4 = grey Signal Out 0-2.3 V 5 = brown Battery + (switched +12 V / 24 V)
Level Adjustment and Start-up: --4-- The operating mode and the setting (calibration, adjustment) of the sensor to tank empty and full is effected by adjusting the built-in rotary encoder with a small screw-driver. Full and empty adjustment must be effected once for adaptation of the sensor to the tank. This is the prerequisite for full measuring accuracy of the sensor. This can be executed in any sequence, i. e. first empty and after that full, or vice-versa, first full and after that empty. If necessary, full and empty adjustment can be repeated at any time individually and independently of each other. There is no mutual influence of the values. Empty Adjustment: 1. Evacuate the tank to the desired minimum level. 2. Set the rotary encoder to the left limit stop EMTY-Cal. (Empty adjustment). The red LED starts lighting. During this time (approx. 5 seconds), the sensor measures the empty value, which will be stored automatically. After that the LED will be flashing, the empty adjustment is finished, and the rotary encoder can be reset to working position 0-2.3 V or 0-10 V. The red LED will extinguish. Full Adjustment: 1. Fill the tank until the desired maximum level is reached. 2. Set the rotary encoder to the right limit stop FULL-Cal. (Full adjustment). The green LED starts lighting. During this time (approx. 5 seconds), the sensor measures the full value, which will be stored automatically. After that the green LED will be flashing, the full adjustment is finished, and the rotary encoder can be reset to working position 0-2.3 V or 0-10 V. The green LED will extinguish. Start-up: Set the rotary encoder to the position of the desired output signal using a small screw-driver: 0-2.3 V: This signal is used for VOTRONIC Tank Displays, such as Tank Display Diesel, LCD Tank Monitor 4 etc. Tank empty = 0 V, linear increase up to tank full = 2.3 V. 0-10 V: This signal is a standard signal for industrial applications of any kind. Among other things, it is used for the VOTRONIC Tank Display LED Tank Display HE 010 and the universal Switching Unit Multiswitch FW. Tank empty = 0 V, linear increase up to tank full = 10 V. The sensor is also able to control several displays in parallel. This function allows simultaneous display of the tank at several locations of the vehicle.
