Votronic 30-110 K-FL User manual

Tank Electrode 30-110 K-FL Tank Height 30 - 110 cm, 12 V and 24 V Order-No. 5551
The tank transmitter had been designed for precise level measuring of fresh water tanks, grey water tanks and
sewage water tanks of plastic and metal material in campers, caravans and boats.
Measurement of the level is effected fully-automatically without mechanically moving parts according to the
capacitive method of measurement, and it is transferred to the display unit via a three-core cable.
The electronic system is completely sealed. Thus, it is extremely robust and insensitive to soiling.
Tank measuring sensor, suitable and required for VOTRONIC tank displays, 1 piece per tank:

For remote level measurement the tank electrode K-FL is
installed directly at the tank. It is suitable for:
•Fresh water (if applicable, please observe the Guidelines
for Drinking-Water Quality DIN 2001-2)
•Sewage water, grey water
•Plastic tanks, any material
•Metal tanks (aluminium, steel, stainless steel, etc.)
•Adjustable to tank heights from 30 cm to 110 cm.
Functioning:
The level in the tank is measured capacitively. The flexible
cable probe and the surrounding water form a kind of
"capacitor", the size of which is growing with the level, and
which is measured by the electronic system.
The contact to the water as "antipole" is effected by a
conductor, connection "com".
Brief Instruction:
1. Produce a mounting hole at the tank with Ø 38 mm or thread PG 29.
2. Determine the kind of installation, inside or outside the tank, and measure the inside tank height.
3. Cut the cable probe to the desired length (observe a clearance of 10-20 mm between probe and tank bottom).
4. Reinsert the insulating cap on the cable probe (observe the tightness).
5. Install the tank transmitter inside or outside using the delivered packing ring.
6. Conductor:
Plastic tank: Produce a bore hole, Ø 9.5 mm (as low as possible at the tank), burr, insert the conductor cable to the
2.8mm faston connector "com", cut it to length and crimp / solder it on the cable lug, insert the rubber dowel, install
the washer and the cable lug by means of the stainless steel screw M5x20, tighten the screw.
Metal tank: Insert the conductor cable to the 2.8mm faston connector "com", and connect it conductively to the tank
close to the transmitter.
7. Set the measured tank height at the scale.
8. Produce the electrical connection to the display unit.
9. Ready for start-up.

Preliminary Installation:
The tank electrode K-FL is designed for vertical installation from the tank top and should be placed at the topmost location
and in the tank centre, mounting hole 38 mm diameter or thread PG 29.
Depending on the local conditions (available space above the tank, cutout of the intermediate floor, tank height etc.), the
tank transmitter can be installed at the tank inside or outside.
Installation from inside Installation from outside
After that, straighten the cable probe, cut it to length and push the insulating cap on the end of the probe.
A safe zero point of the display is ensured, if a clearance of at least 10-20 mm is left between tank bottom and end of the
cable probe (tank bottom bulges up, if the tank is empty, due to deposits etc.).
A thorough sealing of the insulating cap on the cable probe is decisive for proper operation!
Installation of the Conductor at the Plastic Tank:
The conductor establishes the contact to the
water.
Consequently, the bore hole Ø 9.5 mm for the
conductor must be placed as low as possible at
the plastic tank. Burr the bore hole!
Insert the 2.8mm faston connector to "com", cut
the cable to length and crimp/solder the cable
lug.
Install the rubber dowel with washer, cable lug
and stainless steel screw M5x20.
Tighten the screw, until the rubber dowel seals
perfectly.
Connection of the Conductor to the Metal Tank:
Here, the tank establishes itself the contact to the water. Insert the conductor cable to the 2.8mm faston connector "com",
and connect it conductively to the tank close to the transmitter, i. e. screw the cable lug conductively to the tank, adjacent to
the transmitter.

How to set the adjuster Tank Height to "FULL" 100 %:
Example: The scale
indicates
the value 70 cm
tank height
Configuration of Connections:
Colour Connection No. Tank Display Function Recommended Cable Cross-Section
white 5 = Tank +(Plus) + Operating Voltage, from Display Unit Connection 50.5-1 mm²
green 4 = Tank Signal Measuring Signal to Display Unit Connection 4, 0…2.2 V 0.5-1 mm²
brown 1 = Battery -- Operating Voltage (Minus) or Body Ground, 10.5-1 mm²
The tank electrode K-FL is protected against any kind of reverse battery. Despite, it is recommendable to use connection
cables of different colours to avoid malfunctions due to mixed up connections.
As soon as the display unit has been installed according to the operating manual, the battery can be connected.
Start-up and Adjustment:
The adjuster at the upper side of the tank electrode is used to adjust the tank height to 100 % "FULL" at the display:
Insert a folding rule into the mounting hole of the tank to measure the exact tank depth (inside height), and set the adjuster
for the "tank height" (water depth) to this value. The adjustment procedure is completed. The functions of the display can
now be simulated with several water levels in the tank.
Fine adjustment of the set water depth can be corrected or changed at any time with full tank.
Final Installation:
Place the packing washer between tank and casing flange and screw the transmitter in place using the coupling ring PG 29.
In case of underfloor installation of the tank below the vehicle, the adjuster and the "com" connector must be protected
with a permanently elastic sealant against aggressive environmental influences (de-icing salt etc.).
Tips and Tricks:
No reaction of display:
a. Cable 4= Tank Signal Withdraw by way of trial and direct it to connection "5": (Plus):
The display should increase to 100 % ! Otherwise:
b. Battery connection or fuse defective check !
c. Cable 5 = Tank Plus interrupted check !
d. Cable 4 = Tank Signal: Short-circuit to Minus / Ground check !
Constant display of 100 % on the display unit:
a. Cable 4 = Tank Signal Withdraw it and direct it to ground: Display must be empty!
b. Cable 1 = Battery Minus / Ground is interrupted or does not have any contact to the chassis check !
c. The insulated cable probe is contacting to water: The silicone cap is leaky or dropped off, the insulation of the cable
probe is damaged check !
Indication Errors:
a. Intense soiling and furring of the insulated cable probe by stuck solids in the grey water tank and sewage water tanks
Rinse tank or clean it, if required! Do not use salt water!
b. Bad contact of conductor "com" and water , check the 2.8 mm faston connector, the stainless steel screw and the
cable lug.
