VOTRONIC 509643 Tank Electrode 12-24 K Instruction Manual

VOTRONIC 509643 Tank Electrode 12-24 K

INTRODUCTION

According to Drinking Water Ordinance DIN 2001-2
The tank transmitter had been designed for precise level measuring of fresh water tanks, sewage water tanks and feces 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 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
• Feces sewage water
• Plastic tanks, any material
• Metal tanks (aluminium, steel, stainless steel, etc.)
• Adjustable to tank heights: 12 to 24 cm or 15 cm to 50 cm.

Functioning:

The level in the tank is measured capacitively. The insulated stick (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 stainless steel stick.

Brief Instruction:

1. Produce a mounting hole at the tank with a diameter of 38 mm or thread PG29
2. Determine the kind of installation, inside or outside the tank, and measure the tank height
3. Cut both measuring sticks to the desired length (observe a clearance of 10 – 20 mm between sticks and tank bottom)
4. Reinsert the insulating cap on the insulated stick (observe the tightness)
5. Install the tank transmitter inside or outside using the delivered packing washers
6. Set the measured water depth at the scale
7. Produce the electrical connection to the display unit
8. Ready for start-up

Preliminary Installation:

The tank electrode is designed for vertical installation from the tank top.
In contrast to sewage water and feces tanks (deposit), an installation at the lower  side of the tank is also possible.

The tank electrode should be placed at the topmost location and in the tank centre.

Mounting hole, diameter 38 mm, or thread PG29.

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 (for the short type tank electrode 12-24 K is for best results, if possible, the installation outside recommended):

Installation inside

Installation outside

After that, the two stick probes must be cut to identical length (metal saw, strong side cutter, bolt cutter).

It is important, that a clearance of at least 10 – 20 mm is left between tank bottom and probe ends (deposit, up-and-down movement of the tank bottom and of the tank top during driving etc.) Burr the sticks, and reinsert the insulating cap on the stick probe being insulated by the plastic pipe.

A thorough sealing between the insulating cap and the plastic pipe is decisive for proper operation of the tank electrode!

Set the adjuster tank height “FULL” 100 %:

Example: The scale indicates the value 18 cm as adjusted Tank Height

Configuration of Connections

The tank electrode K is protected against any kind of reverse battery. 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 width), and set the adjuster for the “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 (or in a bucket being filled with water) or by withdrawing the tank electrode out of the full tank (or bucket).
Fine adjustment of the set water depth can be corrected or changed at any time with full tank.

Final Installation

The delivered packing washers are placed between tank, casing flange and coupling ring PG 29. Screw the tank transmitter in place using the coupling ring PG 29.

In case of underfloor installation of the tank, the adjuster must be protected with a permanently elastic sealant against aggressive environmental influences (de-icing salt etc.).

Tips and Tricks

No reaction of display:

1. a. Cable 4= Tank Signal Withdraw connector by way of trial and direct it to connection “5”:
   The display should increase to 100 % ! Otherwise:

2. b. Battery connection or fuse defective  check!

3. c. Cable 5 = Tank Plus interrupted  check!

4. d. Cable 4 = Tank Signal: Short-circuit to ground  check!

Constant display of 100 % on the display unit:

1. a. Cable 4 = Tank Signal Withdraw it and direct it to ground: Display must be empty!
2. b. Cable 1 = Battery Minus / Ground is interrupted or does not have any contact due to paint residues at the body check!
3. c. The insulated stick probe is contacting water: The silicone cap is leaky or dropped-off, the plastic pipe is damaged check!

Indication Errors:

• a. Intense soiling and furring of the insulated stick probe by stuck solids in the sewage water tank and feces tank
  • Rinse tank (no seawater), clean it if required !

Safety Regulations and Appropriate Application
