1.0 Complete Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting the
Kotron Model 811 RF Point Level Sensor.
1.1 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. 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 pre-
sent 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 anti-
static 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.

1.3 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. See Mounting, Section 1.4.
Make sure that the wiring between the power supply
and the Model 811 sensor is complete and correct for
the type of installation. See Specifications, Section 2.6.
When installing the Model 811 sensor in a general
purpose or hazardous area, all local, state, and federal
regulations and guidelines must be observed. See Wiring,
Section 1.7.
1.3.2 Equipment and Tools
No special equipment or tools are required to install
the Model 811 sensor. The following items are
recommended:
•1
1⁄8" 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 811 sensor should be located to allow 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.
Units should not be exposed to ambient temperatures
above +160° F (+71° C) or below -40° F (-40° C). Probes
should be isolated from severe motion in the tank, because
surface turbulence may cause signal deviation.
NOTE: The unit is designed for maximum safety intrinsically safe
probe circuit). Jumper (J4) must be intact under normal oper-
ating conditions. The jumper must not be removed by anyone
unless there is a specific need for intrinsically safe grounding
separate from the standard earth ground. Consult factory
before considering special grounding which would require
removal of the jumper. Violation of this requirement will void
warranty and release Magnetrol of any responsibility.
