Page 4: Complete Installation
Complete Installation This section provides detailed procedures for properly installing, configuring, and, as needed, troubleshooting the Kotron Model 811 RF Point Level Sensor. Unpacking Unpack the instrument carefully. Make sure all compo- nents have been removed from the packing material. Check all the contents against the packing slip and report any discrepancies to the factory. -
Page 5: Before You Begin
Before You Begin 1.3.1 Site Preparation Each Kotron Model 811 sensor 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 trans- mitter will be placed. -
Page 6: Mounting
Mounting The Model 811 sensor can be mounted to a tank using a variety of process connections. 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. -
Page 7: Horizontal Mounting
1.4.1 Horizontal Mounting Alarm (narrow differential) applications only Horizontally mounted probes provide a high degree of sen- sitivity for use with non-conductive liquids as only approx- imately 0.5 inches (12 mm) of level change is required to completely cover (or uncover) the probe. Figure 1 Horizontally mounted probes should be installed so that Recommended Horizontal Mounting... -

3. Apply thread sealant to the mounting nut. Screw the mounting nut into the mounting connection until tight. 4. Remove the Mylar housing insulator located over the clamp. DO NOT DISCARD. Probe OPEN (White) 5. Loosen both socket head screws from the clamp. Pull the clamp and Teflon retaining bushing off of the probe. -

1.6.1.2 Probe Housing Connections 1. Screw probe housing onto the probe. PROBE WIRE CONNECTIONS 2. Attach the red guard wire to the slip-on guard connection on probe. Refer to Figure 10a, Probe Wire Connections. 3. Attach the white probe wire to the probe screw on top of the probe. -
Page 11: Wiring
Wiring 1.7.1 Probe Wiring All power and control connections are made at the terminal strip within the amplifier enclosure, EXCEPT GROUND- ING. Power grounding must be made at green ground screw on the housing base. 16AWG is recommended for power and control circuits. NOTE: There are special wiring exceptions for intrinsic safety. -

4.2 Potentiometers a. Time Delay • Allows continuous adjustment of time delay within limits of DIP switch range chosen • Clockwise rotation increases delay. b. Differential • Allows continuous adjustment of pump or valve control ON to OFF. • Clockwise rotation increases differential. Full coun- terclockwise rotation is the narrowest differential and is used for alarm applications. -

1.9 Calibration—Wide Differential 1.9.1 Set Point Adjustment Control 1. Turn on power to the instrument. 2. Remove housing cover. 3. Adjustments 3.1 Dip switch a. Fail-safe ON = high level OFF = low level b. Time Delay Direction ON = delay on rising level OFF = delay on falling level c. - Page 17 • This is an extremely fine adjustment. Sometimes it is necessary to go 1 to 2 turns past the final SETPOINT to stop relay chatter. A small amount of time delay (2 turns) can also be used. 4. The LED shows the status of the relay coil. LED on = relay energized.

3. Measure the resistance between the probe and ground using the highest resistance scale available. If the resistance measures 10 Megohm to infinity and is stable, the probe is operating correctly. If the resistance measures less than 10 Megohm and/or is unstable, there may be a problem with the probe. -
