INSTALLATION
f. The earth bonding arrangement must ensure that the maximum
peak voltage between the unit case earth and any eld cable
conductor is less than 350V. Voltages in excess of this can cause
permanent damage to the unit’s RFI protection lters.
g. The use of a single, screened cable for each gas detector ensures
maximum screening and minimum crosstalk. Cabling arrangements
which use a single cable for connecting a number of eld devices
compromise screening, increase the potential for crosstalk and
prevent implementation of true star earthing.
h. Any electrical interference induced onto the 4 - 20mA loop
conductors by the installation must be kept below the levels
necessary to comply with the general requirements of EN 60079-
29-1 &, IEC 60079-29-1. In practice, this means that
peak noise currents induced on the current loop should be no
greater than ± 0.25mA
j. The 0V rail of the control card/control system is directly connected
to one side of the 4 - 20mA current sensing resistor. Electrical noise
on this rail is therefore directly connected to the 4 - 20mA input.
In order to avoid additional noise being induced on the 0V rail,
it should not be commoned with the safety earth/ground, which
frequently carries a high level of electrical noise.
k. All electrical equipment connected to the gas detector should
comply with EN61000-6-3 and EN61000-6-2.
l. The 24V supply should be free from large transients and
uctuations.
m. The eld cabling conductors should have sufcient cross sectional
area to ensure that the minimum supply voltage applied to the gas
detector is 18V at a current of 420mA. This corresponds to a
maximum round loop impedance of 14 ohms for a nominal 24V
system supply.
n. Receivers should not be installed in close proximity to the antennae
of high powered radio, radar and satellite communication
equipment.
4.3.3 Receiver Connections via OELD
4.3.2 Electrical Installation
1. Isolate all associated power supplies and ensure that they remain OFF
during this procedure.
2. If the units are to be installed with junction boxes other than
OELD or DX100(M) junction boxes, ensure that the boxes:
• have M20 cable gland entries for ATEX / IECEx units, or 3/4 NPT
for UL and CSA.
• have terminals for 5 wires and an earth.
3. Remove the M20 blanking plugs (if tted) and attach the Excel
transmitter and receiver cables to their junction box. Fit the locking
rings (if supplied) before terminating the cables in the junction box.
4. Fit approved cable glands to the junction box cable entries, using
sealing washers where necessary to maintain the ingress protection
rating.
5. Fit approved blanking plugs to all unused cable entries.
6. Make appropriate electrical connections as shown in the following
diagrams.

The earth bonding arrangement must ensure
that the maximum peak voltage between the
unit case earth and any eld cable conductor
is less than 350V. Voltages in excess of this
can cause permanent damage to the unit's RFI
protection lters.
Note: The Dx100(M) is housed in a metal
enclosure.

4. INSTALLATION
INSTALLATION
4.1 GENERAL
Searchline Excel is designed to allow installation to be performed by a
single operator.
The installation procedure is split into mechanical installation and
electrical installation. Each unit needs to mounted to a supporting
structure before making the electrical connections. The diagrams show
different ways of orientation for the mountings.
4.2 MECHANICAL INSTALLATION
This mechanical installation procedure applies to both the receiver and
the transmitter.
1. Ensure that the equipment to be
installed is correct for the type
of installation required (i.e. short/
medium/long range).
2. Fit the mounting bracket to the
mounting plate for the unit, as
shown.
3. Fit the mounting plate to the
supporting structure in one of the
following ways:
• by through bolts directly to a at surface.
• by U-bolts (2 off) to a single 150mm diameter pipe/pole.
• by U-bolts (4 off) to two 55mm diameter pipes/poles,
166mm apart.
Identify the mounting holes using the following diagram and the
accompanying table. The subsequent diagrams show the different
types of mountings.
3.1 GENERAL
This section details the mechanical assembly information and important
dimensions necessary for installing the system units. Adjustable parts which form
part of the mounting assemblies are also shown.

7. Fit an adjustment clamp to the unit’s pivot block mounting stud
so that it sits on the stud’s shoulder with the correct orientation as
shown in the diagram.
INSTALLATION INSTALLATION
4.3 ELECTRICAL INSTALLATION
4.3.1 Electrical Connections
All ranges of Searchline Excel comply with the EMC requirements
EN50270. In order to maintain compliance with these standards it is
essential that the electrical installation of Excel is engineered correctly.
Electrical installation standards vary for different countries, companies
and applications and it is the responsibility of the installation design
authority to determine the applicable standards and ensure compliance
with them. When designing electrical installations for Excel,
Honeywell Analytics Limited recommend that the installation design
authority considers the following:
a. The unit cases should not, if possible, be connected to electrically
noisy (dirty) metalwork or conductors. Preferably, the case
(internally connected to the green/yellow GND wire) should be
connected to a low noise instrument (clean) earth. See also para e.
below. In order to facilitate electrical isolation of the Searchline
Excel from a noisy earth an isolation kit is supplied. This kit should
be tted as standard unless local regulations forbid this.
b. The entire length of the eld cabling connected to each unit should
be fully shielded. This should be connected to a low noise (clean)
earth.
c. The low noise instrument (clean) earth system should only be
connected to safety earth (usually dirty) at a single point on the
entire site/installation. This connection should be made in such a
manner that it does not introduce noise onto the low noise
instrument earth. Star earthing arrangements minimise earth current
crosstalk.
d. The shields of the eld cabling should not be connected such that
earth loops are produced, or in a manner that will result in the
shields carrying large currents from heavy plant or equipment.
e. Ideally, the eld cable shield should be connected to the unit’s
green/yellow GND wire, providing a single, continuous earth shield.
This connection must not be allowed to complete an earth loop.
