1.1 Structure and function
figure 1-1 DIQ/S 182 XT-4-MOD
Sensors Up to four main measured variables (e.g. pH, oxygen content, turbidity
value...) together with their associated auxiliary measured variable
(e.g. temperature) can be displayed and administrated with this
measuring system. According to the number of available main
measured variables, individual sensors (one physical sensor for each
main measured variable) and multiple sensors (one physical sensor for
several main measured variables) from the selection of digital
IQ S
ENSOR NET sensors can be combined and connected.
Each sensor is automatically recognized after being connected and
immediately starts measuring.
Up to four physical sensors can be connected directly to the DIQ/
S 182 XT-4-MOD.

to monitor sensors and for the output of measured values.
A relay output can be programmed as:
a monitoring relay
a limit monitor
a proportional output of measured values (pulse width or frequency
output)
the control unit of a sensor cleaning system driven by compressed
air.
For quick orientation, the states of all relay outputs are clearly indicated
on the display.
Modbus output The Modbus output enables a connection to a Modbus master (Modbus
RTU/RS 485) and thus a connection to a superordinate process
control.
Cleaning system driven
by compressed air
The DIQ/S 182 XT-4-MOD is prepared for the time-controlled sensor
cleaning function driven by compressed air. The cleaning process is
controlled from the operating unit. The operating unit provides the
supply voltage and control relay for the compressed air valve in the
DIQ/CHV valve module. This enables simple setup and uncomplicated
wiring.
Alternatively, the MIQ/CHV PLUS valve module can be installed in the
system. It combines the relay, valve and valve power supply in one MIQ
enclosure. Thus, no additional wiring is required, which makes
installation easier especially if there is a greater distance between the
DIQ/S 182 XT-4-MOD and sensor.
Further system options In case of increased energy demand, an additional power supply unit
can be installed for the power supply if necessary.

3.4 Basic requirements for optimum installation
3.4.1 General information
The System IQ S
ENSOR NET supplies all components with low voltage
as well as digital communication via a shielded 2-wire line.
Because of this characteristic the energy consumption of all
components must be taken into account (power rating) when planning
an IQ S
ENSOR NET system. The energy consumption determines
whether an additional power module is necessary (section 3.4.2).
3.4.2 Drawing up the power rating
Power rating - why? All components in the system require a specific level of electrical power
for operation. Thus, it is necessary to draw up a power rating after
selecting the desired components. At the same time a determination is
made of whether the entire power requirement of all components
(consumers) is covered by the existing power supply in the DIQ/
S 182 XT-4-MOD. If this is not the case, the power available in the
system must be increased by an additional MIQ power supply module.

Allowing for the relative
on-time in valves
Determining the number
of MIQ power supply
modules
Valves usually switch on periodically for a limited time and then require
the nominal power. Crucial for the load on the power unit of the DIQ/
S 182 XT-4-MOD is the time averaged (effective) power requirement
that depends on the relative on-time, ED:
Relative on-time ED = t
/ (tOn + t
On
Off
)
The effective power requirement is the product of the nominal power of
the valve component and the relative on-time:
P = P
nominal
* ED
Since ED is always < 1, the effective power requirement is always
smaller than the nominal power of the valve component.
Note
For the control of sensor cleaning systems operated by compressed
air, a relative on-time of max. 0.1 has been adopted in practice.
From the value determined for the power requirement, determine the
number of the MIQ power supply modules as follows:
Total power requirement P Number of additional
MIQ power supply modules
≤ 4.5 W 0
P
> 4.5 W 1

3.5 Installation guidelines for lightning protection
When using the IQ SENSOR NET instrumentation, particularly in outdoor
areas, adequate protection against (electrical) surges must be
provided. A surge is a summation phenomenon of surge voltage and
surge current. It is generated through the indirect effect of a lightning
event or switching operation in the mains, in the grounding system and
in information technology lines.
To be adequately protected against the damaging effects of surges, an
integrated concept of the following protective measures is required:
internal device-related protective measures and
external protective measures of the installation environment.
The internal device-related protective measures are already integrated
in the YSI online measuring technology as so-called 'lightning
protection' (see chapter 10 T
ECHNICAL DATA).
The external protective measures of the installation environment can
be carried out with respect to the following guidelines:
1 All lines of IQ S
ENSOR NET systems must be
a) installed inside (or else close to) the grounded metallic mounting
constructions, e.g. handrails, pipes and posts if possible
b) or, particularly in the case of longer lines, laid in the ground.
Background: The formation of highly lightning hazardous inductive
loops between the cables and ground is avoided through the low
clearance of the grounded metal construction or by installation in the
ground.
2 Only the SNCIQ or SNCIQ-UG cable material must be used. This
cable material, particularly the high line cross section of the cable
shielding (1.5 mm²), is an important prerequisite for the hazard-free
discharging of the surge without inadmissibly high overvoltages
developing along the line at the same time that could have a
damaging effect on the individual IQ S
ENSOR NET components. It is
not recommended to use cables from other manufacturers with
usually appreciably lower shielding conductor cross sections.
3 All metallic mounting constructions, handrails, pipes, posts etc. on
which MIQ modules are installed must be connected to the local
potential equalization system and the grounding system or must be
individually sufficiently grounded locally according to the codes of
practice.
For the individual grounding of the measuring point the mounting
construction must be solidly connected by means of a large-area
auxiliary electrode with the measuring medium.
Metallic control shafts/pipes and other large-area metallic bodies
that reach into the measuring medium are, for example, ideal for use
ba76028e01 02/2012
3 - 7
Installation System 182 XT-4
in the grounding of the mounting construction.
This creates a set path for the main surge. As a result it is possible
to avoid the surge being discharged via the IQ S
ENSOR NET cable
and via the valuable sensors in the measuring medium.
4 The contacts of the MIQ modules must always be protected by the
associated contact covers if they are not in use. The contact cover
provides improved insulation against the electric fields of a
thunderstorm event through the extension of the air and creepage
paths.
5 It is recommended to attach a metallic or nonmetallic sun shield to
each outside location of the MIQ modules. Sun shields protect the
electric field lines in the area of the MIQ module through an
advantageous development of the electrical field lines in the area of
the MIQ module and promote the dissipation of the surge via the
mounting construction.
6 The mains voltage for supplying the measuring system must comply
with overvoltage category II. Generally this is ensured through the
public operator of the power supply networks. In company-owned
networks, e.g. in all power supply systems owned by wastewater
treatment plants, this must be kept separate by a potential
equalization and a surge protection system for the plant.
7 One part of the IQ S
ENSOR NET safety and lightning protection
concept is based on high-grade protective insulation of the network
components and of the entire system. It does not have or require
any protective ground (PG) conductor or earth terminal. Avoid any
direct connection of the IQ S
ENSOR NET connections or the metallic
sensor enclosures with the local grounding or potential equalization
system and with metallic construction elements (see point 9).
8 Additional external lightning protection measures directly on the
ENSOR NET system or its components, e.g. the use of
IQ S
overvoltage surge arresters, are not necessary for protection
against the indirect effects of lightning and could possibly result in
malfunctions.
9 For the realization of the internal lightning protection of the system
(e.g. wastewater treatment plant control stands) and for the
protection of IQ S
into buildings or distributions coming from the IQ S
ENSOR NET external resources, cable entry points
ENSOR NET must
be carried out as follows:
– The shield of SNCIQ or SNCIQ-UG cables can be connected to
the local potential equalization with a gas overvoltage surge
arrester. Shielding terminals (e. g. of the Modbus system) have
to be used to contact the shield. The shield of the cable must not
be opened under any circumstances.
3 - 8
– 0/4-20 mA interfaces must be realized with shielded cables. The
cable shield must be connected directly to the potential
ba76028e01 02/2012
System 182 XT-4 Installation
equalization(s) provided. If plant potential equalization systems
are provided on both sides, the shield must also be connected on
both sides. The inner conductors must have no contact with the
potential equalization.
– The Modbus cables have to be installed according to the rules of
the relevant bus system.
– Relay lines should be connected to the local potential
equalization in order to provide general and consistent protection
via gas overvoltage surge arresters.
