need for special protective equipment or specific mate-
rials. In this manual, a caution box indicates a poten-
tially hazardous situation which, if not avoided, may
result in minor or moderate injury.
WARNINGS
Warnings identify potentially dangerous situations or
serious hazards. In this manual, a warning indicates an
imminently hazardous situation which, if not avoided,
could result in serious injury or death.
Safety Messages
The Kotron Model 822, 832 and 842 systems may be
properly installed in Category II, Pollution Degree 2
installations. Follow all standard industry procedures for
servicing electrical and computer equipment when
working with or around high voltage. Always shut off the
power supply before touching any components. Although
high voltage is not present in this system, it may be present
in other systems.
Electrical components are sensitive to electrostatic
discharge. To prevent equipment damage, observe safety
procedures when working with electrostatic sensitive
components.
WARNING!
Explosion hazard. Do not connect or
disconnect equipment unless power has been switched off
or the area is known to be non-hazardous.

1.0 Complete Installation
1.0 Complete Installation
This section provides detailed procedures for properly
installing, configuring, and, as needed, troubleshooting
Kotron Model 822, 832 and 842 Sentinel Point Level
Switches.
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.

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:
• 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 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 temper-
atures 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.
