  • Page 4: Introduction

    Introduction Principle of Operation The amount of capacitance developed in any vessel is determined by the size (surface area) of the probe, the dis- tance from the probe to its ground, and the dielectric of the medium being measured. Considering that the probe’s mounting position is fixed, and that the dielectric value of the medium is constant, then the amount of capacitance developed in any vessel becomes dependent upon the...
  • Page 5: Installation

    Installation Caution: Please read the entire installation section carefully prior to starting installation. Unpacking Unpack the instrument carefully. Make sure all compo- nents have been removed from the packing material. Inspect all components for damage. Report any concealed damage to the carrier within 24 hours. Check the contents against the packing slip and report any discrepancies to the factory.

    2.2.2 Tanks/Silos w/Non-Conductive Materials of Construction With plastic, concrete, wood, or any other non-conductive walled vessels, the reference electrode mentioned above needs clarification. Most commonly, this electrode will be in the form of a concentric ground tube (i.e. stilling well). In questionable circumstances, consult the factory.
  • Page 7: Vertical Mounting

    Vertical Mounting Vertically mounted probes provide the capability to adjust the control point up or down a section of probe rod by means of calibration adjustments within the unit’s amplifier. The vertical mounting of a probe rod is the preferred method for application involving coating conductive type liquids or conductive solids.

    2.7.2.2 Relay Wiring Refer to Section 2.7.3, Relay Wiring hart for different relay wiring options. Refer to Section 3.4, Terminal onnections on page 21 for terminal locations. 2.7.2.3 Power Wiring 1. Make sure power source is turned off. 2. Pull power supply wires through conduit connection. Refer to Figure 8 on page 6.
  • Page 14: Wiring Notes And Definitions

    2.7.4 Wiring Notes and Definitions 1. Equipment controlled by the Kotron relays is assumed to be powered from one source, while the Kotron unit itself is assumed to be powered from a different source. 2. There is a fail-safe switch on the Kotron unit, which may be set in either a HL or LL position.
  • Page 15: Fail-Safe Mode Selection

    The position of the jumper is dependent upon the fluid being measured. Locate this jumper in the "LO" position if the fluid is non-conductive (dielectric less than 10); for conductive fluids, position this jumper in the "HI" position. For narrow differential units, always place the jumper in the "LO"...

    2. Set the fail-safe mode for the alarm relays: a. In low level fail-safe mode, the alarm relay will be de-energized when the material level is BELOW the alarm set point. b. In high level fail-safe mode, the alarm relay will be de-energized when the material level is ABOVE the alarm set point.

    4. Turn the zero adjustment counterclockwise until the LED indicator goes off (the relay will change state), then turn the control slowly in the clockwise direction until the indi- cator again comes on. Repeat this on-off operation several times and leave the LED indicator OFF. This completes the zero calibration of the wide differential point.
  • Page 18: Reference Information

    Reference Information Troubleshooting 3.1.1 Probe Caution: When an insulated probe is used in a hazardous and/or abrasive medium, the probe should be inspected annual- ly for any nicks, cuts or abrasions which may ruin the integrity of the insulation. In the event that wear is found, replace the probe or consult the factory for further instruc- tions.

    Caution: This procedure changes any previous calibration of the amplifier. If the unit checks out as operational, it will have to be recalibrated before being used in the process. 3.1.2.1 Narrow differential point units 1. Turn off the power to the unit. 2.
  • Page 20 3.1.2.2 Wide differential point units 1. Turn off the power to the unit. 2. Remove the lead wire from the probe. 3. Turn the zero and span potentiometers fully clockwise. NOTE: On wide differential units, the zero potentiometer is located above the span potentiometer.
