WARNING:

WARNING:

EMC Considerations

• Whenever EMC is an issue, always use shielded cables.

• Never run signal and power wires in the same conduit.

• Use signal wire connections with twisted-pair cables.

• Install Ferrite Bead(s) on signal wires close to the instrument if EMC problems
persist.

Failure to follow all instructions and warnings may result in injury!

Other Precautions

• This device is not designed for use in any medical or nuclear applications.

• Do not operate this device in flammable or explosive environments.

• Never operate with a power source other than the one recommended in this
manual or listed on product labels.

• Do not operate this device outside of the recommended use outlined in this
manual.

• Never use your HPWS transmitter as a portable device. Your unit has been
designed to be operated in a permanent installation only.

• Never install and/or operate your HPWS transmitter closer than 20 cm to
nearby persons.

1.2 Product Labeling

Figure 1-1. HPWS-TX Transmitter/Receiver Label

The main product label contains two white boxed areas that
can be used as write-on surfaces for your convenience. The
bottom box is intended to reference the address code of the
transmitter or receiver. The top box is ‘free-space’ and can be
used for designating where the unit is located or for other
user-desired purposes.

1.3 FCC

This product complies with Part 95 of the FCC rules. Normal operation as
intended by this manual does not require a radio license.

1.4 CE Marking

It is the policy of OMEGA to comply with all worldwide safety and EMI/EMC
regulations that apply. OMEGA is constantly pursuing certification of its
products to the European New Approach Directives. OMEGA will add the CE
mark to every appropriate device upon certification.

Since the HPWS is not intended for use in Europe, CE status has not been
verified at this time.

1.5 General Description and System Components

The HPWS Series long range wireless system allows users to remotely monitor
the status of up to four discrete switches such as level, flow, or other contact
switches. The HPWS-TX transmitters are capable of sending signals to their
corresponding HPWS-REC receivers up to a distance of 8 miles.

The HPWS series wireless system is programmed to work with discrete input,
SPST switches; the HPWS-REC unit can monitor up to four switches located on
one to four HPWS-TX transmitters.
