1. General Informations

1.1 Intention of this Manual

This manual describes the proper use of type 86-EX instruments, their
maintenance and limits.

We want to beware any user from errative measurements and give
examples for the usage.

Please be aware that these high precision electronic instruments for
humidity and temperature must have very sensitive sensors and
electronics which need some care.

Try to reduce the external mechanical and thermal stresses to a minimum
to prolong the lifetime of the instruments.

If any malfunction or technical problems occur, please contact the
manufacturer, representative or dealer of the instrument.

For our Humidity- and Temperature-Instruments we grant warranty
according to the "Allgemeinen Lieferbedingungen für Erzeugnisse und
Leistungen der Elektro-Industrie.”

1.2 Before Using / Safe Operation under EX-Conditions

1.2.1 Unpacking and Checking

Every instrument has been examined before dispatch in respect to its
electrical and mechanical functions. After receipt of instrument, please
check its operation. In case of any malfunction or damage, return the
instrument with a detailed description of faults.

Series 86-EX instruments are normally combined by 3 parts, which are
„Transmitter“, „Probe“ and „Connecting Cable“. The Transmitter has to
supply an intrinsic safe power supply for the probe. The probe is sending
sensor signals which are temperature compensated and are transfered
into linearized analog or digital outputs by digital electronics in the
transmitter. We use a microprocessor for the control of all internal
functions. Using the probe under EX-conditions you only should use an
intrinsically safe cable to connect the probe to the transmitter. These blue
4-wire cables are shielded and confirm with EN 90079-14. The intrinsically
safe power supply and signal wires are not connected to earth-potential
but the cable shield, the housing of the probe and the SS-316 tube of the
probe are connected to earth.

1.2.2 Setup for Operation

The instrument is to be connected to main powers either by a connector or
by using the terminals inside the housing. The correct voltage is marked

HYGROCONTROL Manual for Type 86 Ex Page 4

on the type label you find on one side of the housing. Do not use voltages
other than the marked one! Severe damage would be the result of
applying the wrong voltage.

If your instrument is equipped with screw terminals, the cross section of
your conductors should meet the dimensions of 0.5 up to 1.5 mm2 (AWG
16 to AWG 20). You will find these terminals on the ground PC-board after
opening the housing by turning the four screws (quick-release types) with
a screwdriver to the left. Please take care that cable diameter corresponds
with cable gland dimension and so will guarantee a dense screwing.

If connectors are used for power supply and outputs, we always ship the
neccessary connectors together with the instrument.

1.2.3 On-Site Preparations to fullfill Ex-Regulations

During operation the housing of the instrument should be closed and
the connections between transmitter and probe may not be opened
as long as the cable is in a hazardous area of dust explosion type.
Make sure that before the power supply is activated, an intrinsically
safe cable is used to connect the probe to the transmitter and that all
plugs are thoroughly tightened to assure safe contacts.

User of the instrument have to take care, that not only the power
supply, but also any instrumentation connected to the transmitter is
protected by a fuse of max. 16A, which has a shut-down current of at
least 1500A. If all other instrumentation connected to the transmitter
is powered by the same line, this allows to use one single fuse for
this protection.

Whatever supply is used for the instrument, the PE-contact of the
transmitter must be connected to PE! This is also true, if low voltage
or DC voltage is applied! The tube of the probe has to be connected
to the local potential of the machinery.

Our probes are secure against pressure and vacuum by a glass
feed-through which is specificated from 30 mbar to 30 bar. Use
compression fittings of SS-316 material if applications may have
pressures of more than 1,5 bar.

1.3 Instructions for Dispatch

If there are any problems you are not able to correct, we ask you to
contact our technical department or to return the instrument with a short
description of the fault. When returning please pack the instrument safely
in a cardboard box and fill up holes with soft packing material to avoid
damage.

2.9 Applied Ex-Rules

The type 86-EX instruments are built and certified for applications in the
following EX-Zones and protection Classes:
Probes: Tubes and tips of the probes may be used in Zones 0.
Electronics of probes and connection cables may be used in Zones 1.

Protection Class is EEx ia IIC T4. ATEX-Category for probes is 2G or 2D,
eventually also 1G or 1D, but then a certification of each single instrument
must be done by the proofing authority. Maximum surface temperature of
probe housing and intrinsically safe connection cables is restricted to
60°C.

HYGROCONTROL Manual for Type 86 Ex Page 9

Transmitter: Transmitters built according to EN 50020 as intrinsically safe
supply instruments. Intrinsically safeness is given by Zener Barriers which
are encapsulated together with the connector for the cable to the probe
and therefore may not be manipulated by a user. These Barriers separate
the intrinsically safe power supply for the probes from the internal and
external current and voltage loops which are not intrinsically safe.
