The leading-edge microprocessor-based circuitry has non-volatile memory that requires no battery backup. To simplify troubleshooting, powerful diagnostics not only check all aspects of the system, but will actually indicate the faulty section of the system. MagneCal™ offers the user the greatest improvement in RF Capacitance—one small level change (2% of span) is needed to calibrate. 1.1 Principle of Operation The amount of capacitance developed in any vessel is determined by the size (surface area) of the probe, the distance from the probe to its ground reference, and the dielectric constant of the medium being measured. Assuming that the probe's mounting position and the dielectric of the medium are fixed, the amount of capacitance developed in any vessel becomes dependent upon the probe's diameter and length. Adjusting the combination of the probe's diameter and length (and its proximity to a ground reference) can generate the necessary capacitance required by the electronic circuitry. As the media rises and falls in the tank, the amount of capacitance developed between the probe and the ground reference also rises and falls. The capacitance-controlled oscillator circuit mounted on the probe changes the capacitance signal to a a digital wave form—proportional to the change in level. The Series 804 amplifier then converts this digital pulse signal into an isolated 4–20 mA analog output signal. 1.2 Unpacking Unpack the instrument carefully making sure all components have been removed from the packing material. Inspect all components for damage and report any concealed damage to the carrier within 24 hours. Check the contents of the carton making sure it agrees with the packing slip and the purchase order. Verify that the model number imprinted on the nameplate matches the number on the packing slip and the purchase order. Report any discrepancies to the factory. Check and record the serial number for future reference when ordering parts. 1 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 1.3 Connecting Cable Remote mount connecting cable should be shielded, twisted pair, 22-gauge stranded conductors and may be ordered as Magnetrol part number 009-7146-001. Cable length in feet must be specified at time of order; 2500 feet (760 m) maximum; 800 feet (240 m) maximum for intrinsically safe models. 2.0 Installation Caution: Carefully read this entire section prior to installation. 2.1 Installation Location Kotron Sentinel II Transmitters should be placed in a location which allows easy access for service, calibration, and monitoring. Electronics should not be exposed to ambient temperatures below -40° F (-40° C) nor above +160° F (+70° C). Special precaution should be taken to prevent exposure to corrosive atmosphere, excessive vibration, shock, or physical damage. It is common practice to use the metal tank wall as the ground reference. When doing this, it is required that the probe housing make a good electrical connection to the tank wall. If there is any doubt about this connection (rust or using PTFE thread tape, gaskets, or paint may impede this connection), then a separate strap should be installed between the probe housing and the tank. Sensing probes should be located close to the tank wall for greatest sensitivity in non-conductive media. Isolate probes from severe motion in the tank because surface turbulence may cause signal deviation. Caution: This unit contains CMOS electronics that could be damaged by static electricity. Do not touch any semiconductor devices unless you are properly grounded. Metal-Walled Tanks On water-based liquids, a problem should not be encountered with sensitivity or linearity. With non-conductive, low dielectric media, sensitivity can be enhanced by locating the probe close to and parallel with the tank wall. If this is not practical, a concentric ground tube surrounding the probe (a stilling well) may be a solution. 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 2 Tanks/Silos with Non-Conductive Materials of Construction With plastic, concrete, wood, or any other non-conductive walled vessel, the reference electrode (mentioned in the Principle of Operation section on page 1) needs clarification. Most commonly, this electrode will be in the form of a concentric ground tube (for example, a stilling well). In questionable circumstances, consult the factory. In all cases, a good electrical connection must be made between the ground surface and the probe housing. NOTE: These comments also apply to glass-lined, metal walled tanks. Caution: When an insulated probe is used in a hazardous and/or abrasive medium, the probe should be inspected annually for 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 instructions. This procedure is critical in vessels containing hazardous media. Tank mounting bushing Mounting nut 2.2 Mounting Probes should be mounted vertically and such that the probe rod is at least 2" (50 mm) below the lowest desired level control point with conductive materials; or, 4" (100 mm) below the lowest desired level control point in non-conductive materials. Refer to Figure 1. 2" Actuation point in conductive media Figure 1 2.2.1 Mounting Procedure Kotron Sentinel II Transmitters with standard probes up to and including 12" (305 mm) in length are shipped preassembled. Units with standard probes over 12" (305 mm) in length are shipped unassembled to avoid damage during transit; and must be assembled before mounting. Follow the proper mounting procedure for specific unit. NOTE: Before beginning mounting procedures, ensure that the power source to the unit is off. After installing the probe on the tank, and before wiring the electronics to the probe, it is beneficial to perform a probe resistance check to verify the integrity of the probe. The resistance of an insulated probe in conductive liquid (or a bare probe in non-conductive media), when measured between the probe screw terminal and the probe mounting nut with an ohmmeter set to its 20 megohm scale, should be INFINITE. 2.2.2 Integral Mount with Standard Rigid Probe 1.

These instruments utilize electronic components which may be damaged by static electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge: 1. Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap board in aluminum foil. Do not place boards on foam packing materials. 2. Use a grounding wrist strap when installing and removing circuit boards. A grounded workstation is also recommended. 3. Handle printed circuit boards only by the edges. Do not touch components or connector pins. 4. Ensure that all electrical connections are completely made and none are partial or floating. Ground all equipment to a good, earth ground. 2.4 Wiring 2.4.1 Wiring Power Supply Board For connection of power and control circuit, 16–22 AWG stranded wire is acceptable. Refer to Figures 6 and 7 for power supply board layout and terminal locations. 2.4.1.1 Power wiring Active/Passive switch selectors Passive Active (+) 4–20 mA (–) terminals A B 1. Ensure that power source is turned off from unit. 2. Pull the power supply wires through the conduit connection. 3. Connect the positive (hot) supply wire to the L1 on terminal block TB1. 4. Connect the negative (neutral) supply wire to the L2/N on terminal block TB1. 5. Connect the ground wire to the green screw in the housing base. 2.4.1.2 Discrete output wiring NOTES: Output #1 may be used as a dedicated diagnostic alarm. } } RS-485 terminals } Manual self-test Remote contact Figure 6 Logic Board Terminal Connections Any or all outputs can be used for LEAD/LAG pump sequencing. 9 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 2.4.2 Wiring Operation 2.4.2.1 4–20 mA output wiring Relay 1 (TB2) Relay 2 (TB3) NO CO NC NO CO NC NO Relay 3 CO NC (TB5) NO Relay 4 CO NC (TB4) Connect the positive wire to the + terminal; connect the negative wire to the – terminal. 2.4.2.2 Active or passive selection Input power (TB1) L1 (+) Not used L2/N (–) The 4–20 mA output can be configured for active or passive operation. Active mode allows the Sentinel II to drive the loop (for example, the Sentinel II is the 24 VDC power supply). The passive mode allows the Sentinel II to react like a loop-powered transmitter (the loop power is supplied elsewhere). Switch S1 changes the mode. See Figure 6 on page 9. Figure 7 Power Supply Board Terminal Connections Cable should be shielded, twisted pair, 22 gauge stranded conductors. In the active mode of operation the shield should be grounded at the model 804. In the passive mode the shield should be grounded at the power source. Caution: Applying power to the 4–20 mA output, while in the active mode, will seriously damage the instrument. 2.4.2.3 RS-485 output RS-485 communication is achieved by means of a 2-wire, twisted pair connected to terminal block. 1. Connect the A wire from the control room converter to terminal A. 2. Connect the control room converter wire B to terminal B. NOTE: Polarity among units in loop must be observed. 3. If connecting multiple 804 units in a daisy chain configuration, be sure to connect the wiring in parallel and have the ending 804 unit with the termination resistor jumpered. The termination jumper pins are located under the shield, below the RS-485 terminal block. The jumper (JP1) should be in positions 2 and 3, removed on all units except the last one in the chain. The last unit should have the jumper in positions 1 and 2. 4. Proceed to Unit Configuration section on page 11. NOTE: If connecting several units, note the color wire used for A and B; ensure that the same designated color is used for each of the units. 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 10 2.4.2.4 Manual self-test A manual self-test can be performed on the 804 electronics. A remote contact should be wired across terminals 1 and 2 with terminal 3 used for shield if needed. Performing a manual self-test will cause the 804 to go into alarm mode. The relays and mA output will change to the mode selected in the Unit Configuration. 2.5 Unit Configuration 2.5.1 General Configuration Instructions The Kotron Sentinel II RF Capacitance Level Transmitter contains a microprocessor-based operator interface, which allows easy configuration of level measurement or control applications. These simple-to-use features are accessed through the 16-digit keypad, located on the front of the unit’s shield. The operator interface and instructions for the unit configuration are broken down into five main groups of menus: MEASURED VALUES: For viewing the measured values SYSTEM CONFIG: I/O CONFIG: Probe calibration Configure the input/output functions (such as 4–20 mA and relays) Set the unit’s advanced features (such as password and display options) ADV CONFIG: DIAGNOSTICS: Enhanced troubleshooting features. 2.5.2 Password The Sentinel II has a built-in password system to restrict access to portions of the menu that affect the unit’s operation. The password is required whenever programming values are being changed. The password can be changed to any four digit number desired. This procedure is described under the ADV CONFIG menu page 13. Caution: The Sentinel II is shipped from the factory with the password 0804. If the programmed password is misplaced or forgotten, consult the factory for assistance. 2.5.3 Operator Keypad All unit configuration instructions in this manual will show the local transmitter display exactly as it will appear to the operator. The operator interface is via a keypad consisting of the following keys: 11 50-604 Kotron Model 804 Sentinel II RF Level Transmitter Key 0–9 .

This system also allows the user to test the 4–20 mA and discrete (relay) outputs to ensure satisfactory operation of the system. The following section defines each function of the diagnostics system: 3.1.1 Test Relays The Test Relays menu provides a controlled contact closure for each relay to test its integrity. A password is required. 3.1.2 Test 4–20 Output The 4–20 Loop Output menu provides a means for testing the 4–20 mA output. Once the desired loop current is entered, the Model 804 will drive the output loop to this current value. 3.1.3 Signal Values The Signal Values menu provides a means of examining the signals between the probe and the CCO (Capacitance Controlled Oscillator). The three signals are: 3.1.3.1 CCO int. cap. This signal represents the time period of the oscillator using the internal test capacitor. This fixed capacitor is switched into the circuit to test the oscillator. A value of approximately 475 and 525 µsec. is acceptable. 3.1.3.2 Open probe This signal represents the time period of the oscillator with no capacitor attached (the probe and the fixed capacitor are switched out of the circuit). A value between 150 µsec. and 250 µsec. is acceptable. 3.1.3.3 CCO probe This signal represents the time period of the oscillator using the probe’s capacitance The minimum should be equal to or greater than the open probe value; the maximum should not exceed 70,000 µsec. 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 20 3.1.4 View Version # The View Version # menu enables the user to verify the version number of the software of the unit. 3.1.5 Factory Presets The Factory Presets menu allows setting of special factory functions. This menu should only be used with guidance from factory personnel. Contact the factory for assistance. 3.1.6 Troubleshooting Procedures The chart below describes error messages that can appear on the Sentinel II display. Display Cause The capacitance being measured by the unit is too low. Possible causes include missing probe; missing/broken probe wire; or a poorly connected probe wire. Probe resistance between the center connection and mounting nut is less than 1 megohm. Possible causes include a bare probe in conductive media or a damaged insulated probe in a conductive media. Probe capacitance exceeds 50,000 pF. Occurs when the oscillator is not receiving a signal. Possible causes include a shorted probe; missing/broken interconnection cable between the preamplifier and the main electronics (remote only); or a defective circuit board. Solution Check the interconnection wire between the probe and the preamplifier. Open probe Shorted probe Check the probe resistance by connecting an ohmmeter between the center connection and the mounting nut. If the resistance is less than infinity, contact the factory. Probe error Contact the factory for application assistance. No return signal If the probe is a shorted probe, follow the instructions above for shorted probe. 21 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 3.2 Agency Approvals MODEL APPROVED APPROVAL CATEGORY APPROVAL CLASSES AGENCY FM 804-XXXX-23X 804-XXXX-33X Explosion proof Insulated probes only Integral units Explosion proof with I.S. probe Remote units Explosion proof Remote probe Intrinsically Safe 804-XXXX-53X 804-XXXX-63X CSA 804-XXXX-23X 804-XXXX-33X Explosion proof Insulated probes only* Integral units Explosion proof with I.S. probe Remote units Explosion proof Remote probe Intrinsically Safe 804-XXXX-53X 804-XXXX-63X Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class Class I, Div. 1; Groups B, C, & D II, Div. 1; Groups E, F, & G III, NEMA 4X IP66 I, Div. 1; Groups B, C, & D II, Div. 1; Groups E, F & G III, NEMA 4X IP65 I, Div. 1; Groups B, C, & D II, Div. 1; Groups E, F & G III, NEMA 4X IP65 I, Div. 1; Groups A, B, C, & D II, Div. 1; Groups E, F & G III, NEMA 4X IP65 I, Div. 1; Groups C, & D II, Div. 1; Groups E, F, & G III, Type 4X I, Div. 1; Groups C, & D II, Div. 1; Groups E, F & G III, Type 4X I, Div. 1; Groups B, C, & D II, Div. 1; Groups E, F & G III, Type 4X I, Div. 1; Groups A, B, C, & D II, Div. 1; Groups E, F & G III, Type 4X These units have been tested to EN 50081-2 and EN 50082-2 and are in compliance with the EMC Directive 89/336/EEC. *For Class II, Groups E & F, insulated probes must be used. 50-604 Kotron Model 804 Sentinel II RF Level Transmitter 22 3.2.1 Agency Specifications – Intrinsically Safe Installation (FM/CSA) INTRINSIC SAFETY Model 804-XXXX-53X and 804-XXXX-63X are FM and CSA agency approved for use as an intrinsically safe circuit per the instructions on Drawing 99-5053-001 (Figure 8) shown below.

They will be rebuilt or replaced promptly. Controls returned under our service policy must be returned by prepaid transportation. Magnetrol/STI will repair or replace the control at no cost to the purchaser (or owner) other than transportation if: 1. Returned within the warranty period; and 2. The factory inspection finds the cause of the claim to be covered under the warranty. If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be charges for labor and the parts required to rebuild or replace the equipment. In some cases it may be expedient to ship replacement parts; or, in extreme cases a complete new control, to replace the original equipment before it is returned. If this is desired, notify the factory of both the model and serial numbers of the control to be replaced. In such cases, credit for the materials returned will be determined on the basis of the applicability of our warranty. No claims for misapplication, labor, direct or consequential damage will be allowed. Return Material Procedure So that we may efficiently process any materials that are returned, it is essential that a “Return Material Authorization” (RMA) number be obtained from the factory, prior to the material's return. This is available through Magnetrol’s local representative or by contacting the factory. Please supply the following information: 1. 2. 3. 4. 5. Company Name Description of Material Serial Number Reason for Return Application Any unit that was used in a process must be properly cleaned in accordance with OSHA standards, before it is returned to the factory.
