Make sure all components have been removed from the packing material. Check all the contents against the packing slip and report any discrepancies to the factory. Before proceeding with the installation, do the following: • Inspect all components for damage. Report any damage to the carrier within 24 hours. • Make sure the nameplate model number agrees with the packing slip and purchase order. • Record the model and serial numbers for future reference when ordering parts. 1.2 Electrostatic Discharge (ESD) Handling Procedure Magnetrol’s electronic instruments are manufactured to the highest quality standards. These instruments use electronic components that 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. • Ship and store circuit boards in anti-static bags. If an antistatic bag is not available, wrap the board in aluminum foil. Do not place boards on foam packing materials. • Use a grounding wrist strap when installing and removing circuit boards. A grounded workstation is recommended. • Handle circuit boards only by the edges. Do not touch components or connector pins. • Make sure that all electrical connections are completely made and none are partial or floating. Ground all equipment to a good, earth ground. 1 50-621 Kotron Sentinel Models 822, 832 and 842 RF Point Level Switches 1.3 Before You Begin 1.3.1 Site Preparation Each Kotron Model 822, 832 and 842 switch is built to match the specific physical specifications of the required installation. Make sure the probe connection is correct for the threaded or flanged mounting on the vessel or tank where the switch will be placed. See Section 1.4, Mounting. Make sure that the wiring between the power supply and the Model 822, 832 or 842 switch is complete and correct for the type of installation. See Section 3.2, Specifications. When installing the Model 822, 832 or 842 switch in a general purpose or hazardous area, all local, state, and federal regulations and guidelines must be observed. See Section 1.7, Wiring. 1.3.2 Equipment and Tools No special equipment or tools are required to install the Model 822, 832 or 842 switch. The following items are recommended: • 11⁄8" open-end wrench or adjustable wrench to fit the probe process connection size and type. • Flat-blade screwdriver 1.3.3 Operational Considerations The Model 822, 832 or 842 switch should be located for easy access for service, configuration, and monitoring. There should be sufficient headroom to allow the probe to be inserted into the tank. Special precautions should be made to prevent exposure to corrosive atmosphere, excessive vibration, shock, or physical damage. The electronics should not be exposed to ambient temperatures above +160° F (+70° C) or below -40° F (-40° C). The proper operating temperature range for the display is -4° F (-20° C) to +160° F (+70° C). The temperature limits for the probe depend on the style and part number of the specific probe used. 50-621 Kotron Sentinel Models 822, 832 and 842 RF Point Level Switches 2 1.4 Mounting The Model 822, 832 or 842 switch can be mounted to a tank using a variety of process connections. Generally, either a threaded or flanged connection is used. For information about the sizes and types of connections available, see Probe Brochure 50-125. Make sure all mounting connections are properly in place on the tank before installing the probe. Make sure the Kotron probe is correct for the intended installation. It is common practice to use the metal tank wall as the reference electrode. In such cases, it is required that the probe housing makes a good electrical connection to the tank wall. If there is any doubt about this connection or to the use of PTFE thread tape gaskets, paint, rust, or any other reason, a separate strap should be installed between the probe housing and the tank. Caution: This unit contains CMOS electronics which may be damaged by static electricity. Do not touch any semiconductor devices unless you are properly grounded. Caution: When a probe is used in an abrasive medium, inspect the probe periodically for visible surface wear. If damage to the probe insulation is found, replace the probe. Metal Walled Tanks On water-based liquids, there should be no problem 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 ground reference probe may be the solution. Non-Metallic and Glass-Lined Tanks With plastic, concrete, wood, or any other non-conductive walled vessels a ground reference is required. Most commonly, this electrode will be in the form of a concentric ground tube (i.e., 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. Switch/Probe Assembly Switches with probes up to and including 12 inches (300 mm) in length are shipped pre-assembled. All other switches are shipped unassembled to avoid damage during transit. These transmitters must be assembled prior to mounting. Choose your particular configuration from the following sections and follow the instructions carefully. 3 50-621 Kotron Sentinel Models 822, 832 and 842 RF Point Level Switches 1.4.1 Horizontal Mounting Alarm (narrow differential) applications only Figure 1 Recommended Horizontal Mounting Horizontally mounted probes provide a high degree of sensitivity for use with non-conductive liquids as only approximately 0.5 inches (12 mm) of level change is required to completely cover (or uncover) the probe. Horizontally mounted probes should be installed so that the probe is parallel to and at the level at which the control point is desired. Refer to Figure 1. Avoid any installation method in which the material may become trapped in the mounting nozzle, thus preventing the probe from signaling when the level recedes. Refer to Figures 2 and 3. NOTE: If nozzle mounting is unavoidable, the probe must be installed with an inactive metal sheath having a length of at least 1 inch (25 mm) greater than length of the nozzle. A sheath is required to render the length of the probe within nozzle insensitive to capacitance change. Refer to Figure 2. Figure 2 Recommended Mounting with Nozzle Figure 3 Not recommended Guarded Probe Unit will signal at probe level. Refer to Figures 4 and 5. NOTE: The guard element must be located outside of the nozzle. Do not horizontally mount the unit in a nozzle deeper than 3 inches (75 mm). Refer to Figure 5. The medium may buildup in the nozzle and cause false activation. Figure 4 Recommended Horizontal Mounting Alternate Horizontal Mounting On applications involving viscous liquids or materials which tend to cling or buildup, horizontally mounted probes should be installed at a slight downward angle to allow material to drain from probe rod. With this type of installation, the packing gland face of probe assembly should extend into the tank (or vessel). Refer to Figure 6. 1.4.2 Vertical Mounting Figure 5 Recommended Horizontal 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. Vertically mounted probes should be installed so that the end of the probe rod is at least 2 inches (50 mm) below the lowest desired level control point with conductive materials or 4 inches (100 mm) below the lowest desired level control point with non-conductive materials. Refer to Figure 7 on page 5.

These features are built into the controller and are entered via three tactilearrow, DOWN arrow, and feedback keys (UP ENT ) located on the amplifier circuit board. In addition, a 4-digit LED displays the operating parameters and values. The keys and their functions are shown below. ENT Upon power up, the LED will display the following message: Magnetrol Int’l followed by a series of walking M’s (multi-point) or S’s (single point), based on the calibration configuration selected. This is the normal RUN mode. UP/RAISE: Use to scroll up through menu selections, or raise numeric values. There are three speeds for scrolling numeric values. Ramp speed is increased by continuously arrow key. To decrease speed as the depressing the UP arrow key desired value is approached, release the UP and unit will revert to the slowest ramp speed. DOWN/LOWER: Use to scroll down through menu selections or lower numeric values. There are three speeds for scrolling numeric values. Ramp speed is increased by arrow key. To continuously depressing the DOWN decrease speed as the desired value is approached, release arrow key and the unit will revert to the DOWN slowest ramp speed. ENT ENTER: Use to select displayed value and to continue to the next menu selection. Complete menu layouts are provided to show the user-selectable parameters. NOTE: The unit will automatically time out and revert to the RUN mode after 60 seconds of no key strokes. Any information already entered is secure, and the calibration may be safely resumed at any time. 50-621 Kotron Sentinel Models 822, 832 and 842 RF Point Level Switches 10 The microprocessor-based Sentinel offers all operator functions and setup procedures from the three tactile-feedback keys described above. Due to the number of user programmable features included in the unit, the calibration flow chart is extensive. The flow chart is modular, however, it can be divided into five subsections or program paths which are connected to a home base, or normal operating mode, RUN (walking M or S). When letters scroll horizontally across the LED and no error messages are displayed, all systems are functioning properly. The calibration flow chart structure is shown on page 12. NOTE: If MagneCal precalibration data was entered at the factory, use Advanced Calibration procedures (Section 2.5) in conjunction with the standard calibration procedures. 2.2 Program Paths In order to properly calibrate the Sentinel, the Calibration instructions are broken down into the five PATHS described below.

The MULT (multi-point) program is for all pump (wide differential) control, multiple relay applications, and single point applications where an adjustable set point is needed. NOTE: Specific order of the configuration modes must be followed for proper calibration of the Sentinel Level Switch. It is imperative that the user select CNFG for the first calibration procedure. Within the CNFG mode, the single or multi-point operation must be selected. This selection affects the balance of the configuration procedures and will significantly affect the RUN performance of the level switch if the modes of operation are not followed.
