3.2 Restrictions on use
DANGER
Use of operating devices in explosive areas
The use of additional components, such as operating devices or tablets, which are not designed for
use in explosion hazard areas, can trigger explosions.
uWithin explosion hazard areas, use only components approved for this purpose.
3.3 Non-intended use
DANGER
Dangers in case of non-intended use.
Incorrect use of the device can result in injuries to persons, process-related consequential damage
and damage to the device and its periphery. In the following cases, the manufacturer cannot guaran-
tee the protection of persons and the device and therefore does not accept any liability:
uThe device is used outside the area of application.
uThe device is not installed, set up or transported properly.
uThe device is not installed and operated according to the instruction manual.
uThe device is operated with accessory parts not expressly recommended by SIGRIST-PHOTOME-
TER AG.
uImproper modifications are made to the device.
uThe device is operated outside the specifications.
uThe device is exposed to shocks, vibrations or other mechanical forces.
3.4 Warnings
The warnings are four-tiered: Danger, warning, caution, notice. They include: Nature of the hazard,
possible consequences and measures to avert it.
Signal word Meaning
DANGER
Signal word to indicate a hazard with high risk, which will directly result in
death or serious physical injury.

Your Safety
SIGRIST-PHOTOMETER 9 / 68
Signal word Meaning
WARNING
Signal word to indicate a hazard with medium risk, which can possibly result
in death or serious physical injury.
CAUTION
Signal word to indicate a low-risk hazard that may result in minor or moder-
ate bodily injury.
NOTICE
Signal word for a potentially harmful situation in which the equipment or an
object in its vicinity may be damaged.
3.5 Residual risks
The device was built in accordance with the applicable standards and the recognized safety rules. It
corresponds to the state of the art. Nevertheless, injuries to persons, damage to the device or mate-
rial damage to the infrastructure may occur during use.
Danger due to explosion
Opening the photometer in the explosive area can lead to an explosion.
uOnly open the device after the service voltage has been interrupted and disconnected from all con-
ductors.
uDo not make any amendments to the housing. There is no provision for repair of the flameproof
joint.
Danger from electricity
The device is operated with 24 VDC. If a power supply unit (100...240 VAC) is also used, there is a
risk of electric shock with fatal consequences if open cables are touched.
uDo not operate the device unless it has been properly installed and repaired Nameplate [}11].
uOnly operate the device if all cables are undamaged.
uNever operate the power supply with the case removed or open.
Danger due to high pressures
Servicing, repairs or adjustments to a pressurized pipeline may result in personal injury, damage to
the equipment or property damage to the infrastructure.
uBe sure to drain the process line before removing the photometer.
uAlways consult the Start for servicing, repairs or adjustments to pipelines.
Danger due to liquids
Escaping medium at the device or at the connections can lead to flooding of the room and cause ma-
terial damage to the infrastructure.
uCheck for leaks regularly.
Ingress of moisture and condensation on electronic components can cause damage.
uCarry out servicing and repair work inside the device only in dry rooms and at operating or room
temperature.
uAvoid accumulation of condensation on optical and electrical surfaces.
Danger from aggressive chemicals used for cleaning
The use of aggressive cleaning agents may damage components of the device.
uDo not use aggressive chemicals or solvents for cleaning.
uIf the device has nevertheless come into contact with aggressive chemicals, check it immediately
for damage.

Your Safety
10 / 68 SIGRIST-PHOTOMETER
Risk of leakage at the process line
Leakages at the process line can lead to escaping medium. Contact with the medium can lead to
burns, chemical burns or poisoning with a fatal outcome.
uEnsure that the device meets the requirements of the medium.
uTake protective measures and wear protective clothing.
Faulty measured value display during operation
An incorrect measured value display cannot be ruled out in accordance with the risk assessment of
the used safety standard DIN EN 61010-1.
uApply the access code to prevent parameters from being changed by unauthorised persons.
uPerform the specified servicing duty.
Unauthorised Internet access
Unauthorised access to the Internet by third parties can change the configuration and therefore faulty
measurements cannot be ruled out.
uEnsure compliance with the safety measures on the part of the operator to prevent unauthorised
Internet access.

5 Mounting
5.1 Requirements
For the mounting of the photometer and its additional components, the detailed dimension drawings
must be observed. The following provisions apply to the applications.
The photometer must be installed in the line at least 2 m away from sight glass or other sources of
interfering light.
Incorrect mounting may result in the formation of
deposits or accumulation of air bubbles. The de-
vices must not be mounted standing (upwards) or
hanging (downwards).
The photometer can be mounted with a standard-
ised in-line housing or a flange connection with a
special measuring cell, both in horizontal and ver-
tical process lines. In the vertical fitting position,
the cable penetration must point downwards. For
horizontal fitting, the cable penetration is on the
side.
5.2 Installation on VARINLINE®connector
uMount the photometer (1) including seal (7)
with clamp ring (6) on the VARINLINE® con-
nector.
uEnsure that the groove (2) points in the flow
direction.
uMount the blanking plate (3), including
seal(4) with clamp ring (5) on the VARIN-
LINE® connector.

6 Electrical installation
DANGER
Danger due to improper connection of the service voltage.
Improper connection of the electrical service voltage can be life-threatening. The system can also be
damaged in the process.
uConnection must be carried out by a specialist in accordance with local regulations.
uInstall a suitable disconnection device close to the service voltage, which is easily accessible and
marked.
uIt is mandatory to connect the protective conductor.
6.1 Requirements
Carry out the installation in the explosion hazard area in accordance with EN 60079-14 and observe
the following:
uDo not shorten the supplied cable.
uInstall an explosion-proof electrical enclosure/disconnection device.
uWithout an explosion-proof electrical enclosure/disconnection device, run cable into explosion-
proof room and connect there.
uConnect the shielding of the conducting cable.
6.2 Photometer connection
The shielding of the 8-pole conducting cable is connected to the housing on the device manufacturer
side. The function configuration of the individual strands depends on the installed communication
module (Nameplate [}11]).

Operation
20 / 68 SIGRIST-PHOTOMETER
7 Operation
The device can be operated via the proximity sensor (TOUCH) with the finger directly on the device
display or with WLAN-capable devices.
7.1 Operation on TurBiScat 2 Ex
7.1.1 Operating elements
You can switch between the different menu items by touching them.
lShort touch (<0.5s): navigate between menus
lLong touch (1...2s): Navigate within a menu
For the input to be recognized, the finger must be lifted at least 5 cm after the touch. Without activ-
ity, the display changes to the measurement monitor after one minute.
