2 Safety information for TRANSIC151LP Ex
2.1 Important information
WARNING: Risk of fire through strong oxidation processes
High O concentrations have strong oxidizing properties. These
2
increase the risk of combustion and can trigger violent reactions with
inflammable substances.
Before installation, check the TRANSIC151LP is suitable for your
application with regard to all ambient conditions.
2.2 Intended use
The TRANSIC151LP is a stationary oxygen transmitter and serves continuous
measurement of oxygen in the industrial sector.
There are 3 variants of the TRANSIC151LP:
1. In-situ measurement
2. Extractive measurement
3. Measurement in ambient air
● The TRANSIC151LP is certified for a process-side operating range of
800 mbar abs. to 1400 mbar abs. Usage with deviating pressures can void
the Ex certification.
● The TRANSIC151LP must be operated within the specifications described
in the Section Technical Data. The Ex certification becomes void when the
TRANSIC151LP is operated outside the specifications.
● The TRANSIC151LP has not been evaluated regarding the safety function
as laid out in 94/9/EC, Annex II, Section 1.5.
Operation in potentially explosive atmospheres
The TRANSIC151LP is suitable for the following zones in accordance with
ATEX (EN 60079-10) and in accordance with IECEx (IEC 60079-10)
● Gas:
– Measuring probe: Category 1G EPL Ga (Zone 0)
– Transmitter/voltage supply unit: Category 2G EPL Gb (Zone 1)
● Dust:
– Transmitter/voltage supply unit/measuring probe: Category 2D EPL Db
(Zone 21)
The TRANSIC151LP may be used in zones in which inflammable or explosive
gases in groups I, IIA and IIB or inflammable dust in groups IIIA, IIIB and IIIC
are present.
● Temperature class:
– Gas: T4 (max. surface temperature 135 °C)
– Dust: T85 °C

●
Do not remove, add or modify any components to or on the device
●
unless described and specified in the official manufacturer informa-
tion. Otherwise the approval for use in potentially explosive
atmospheres becomes void.
Adhere to the maintenance intervals.
The TRANSIC151LP may only be used in zones corresponding to the
Ex marking (see type plate) of the transmitter and the power supply
unit. Check the requirements of the installation location with the Ex
certification of the device.
The TRANSIC151LP may only be installed by persons trained in the
standards used (e.g., EN/IEC 60079-14).
The TRANSIC151LP may not be modified. Any modification to the
device voids the Ex certification.
Operation in potentially explosive atmospheres
The TRANSIC151LP is suitable for the following zones
In accordance with ATEX (EN60079-10) and IECEx (IEC60079-10)
● Gas:
– Measuring probe: Category 1G EPL Ga (Zone 0)
– Transmitter/voltage supply unit: Category 2G EPL Gb (Zone 1)
● Dust:
– Transmitter/voltage supply unit/measuring probe: Category 2D EPL Db
(Zone 21)
The TRANSIC151LP may be used in zones in which inflammable or explosive
gases in groups I, IIA and IIB or inflammable dust in groups IIIA, IIIB and IIIC
are present.
Temperature class: Gas: T4 (max. surface temperature 135 °C); Dust:
T85 °C.
CAUTION: Observe marking for special operating conditions
Special operating conditions: Marking "X" on the TRANSIC151LP type
plate means the wall thickness of the temperature probe is
0.2<t<1 mm. In order to maintain the zone separation, the tempera-
ture probe may not be exposed to ambient conditions that can
endanger zone separation.
Check the condition of the temperature probe during every regular
maintenance.
CAUTION: Observe marking for special operating conditions
Special operating conditions: Marking "X" on the TSA151 type plate
means a PELV power supply unit is mandatory for voltage supply to the
TSA151.
The 24V inlet of the TSA151 is specified with a fault voltage of
Um=60V and therefore requires an appropriate PELV power supply
unit.
