2.1 Intended use

The temperature transmitter T53.10 is a universal, congurable

transmitter for use with single and dual resistance thermometers
(RTD), thermocouples (TC), resistance and sensor sources as well
as potentiometer measuring.

The temperature transmitter has been designed and built solely for
the intended use described here, and may only be used accordingly.

The technical specications contained in these operating instruc­tions must be observed. Improper handling or operation of the instru-

ment outside of its technical specications requires the instrument

to be shut down immediately and inspected by an authorised WIKA
service engineer.

Before installation, commissioning and operation,
ensure that the appropriate temperature transmitter has
been selected in terms of measuring range, design and

specic measuring conditions.

Non-observance can result in serious injury and/or
damage to equipment.

Further important safety instructions can be found in the
individual chapters of these operating instructions.

If the temperature transmitter is transported from a cold into a warm
environment, the formation of condensation may result in the instru­ment malfunctioning. Before putting it back into operation, wait for the
instrument temperature and the room temperature to equalise.

The manufacturer shall not be liable for claims of any type based on

Installation notes:

FM / CSA:

For installation in the US the equipment shall be installed according to the National
Electrical Code (ANSI-NFPA 70).

GB

For installation in Canada the transmitter shall be installed in a suitable enclosure to meet
installation codes stipulated in the Canadian Electrical Code (CEC).

The entity concept:

Equipment that is FM / CSA-approved for intrinsic safety may be connected to barriers
based on the ENTITY CONCEPT. This concept permits interconnection of approved

transmitters, meters and other devices in combinations which have not been specically

examined by FM / CSA, provided that the agency‘s criteria are met. The combination is
intrinsically safe, if the entity concept is acceptable to the authority having jurisdiction over
the installation.

The entity concept criteria are as follows:
The intrinsically safe devices, other than barriers, must not be a source of power.
The maximum voltage U
which the device can receive and remain intrinsically safe, must be equal to or greater
than the voltage (Uo or VOC or Vt) and current (Io or ISC or It) and the power Po which can
be delivered by the barrier.
The sum of the maximum unprotected capacitance (Ci) for each intrinsically device and
the interconnecting wiring must be less than the capacitance (Ca) which can be safely
connected to the barrier.
The sum of the maximum unprotected inductance (Li) for each intrinsically device and
the interconnecting wiring must be less than the inductance (La) which can be safely
connected to the barrier.
The entity parameters Uo, VOC or Vt and Io, ISC or It, and Ca and La for barriers are provi­ded by the barrier manufacturer.

FISCO/FNICO rules:
The FISCO Concept allows the interconnection of intrinsically safe apparatus to

associated apparatus not specically examined in such combination. The criterion for

such interconnection is that the voltage (V
intrinsically safe apparatus can receive and remain intrinsically safe, considering faults,
must be equal or greater than the voltage (Uo, VOC, Vt), the current (Io, ISC, It) and the
power (Po) which can be provided by the associated apparatus (supply unit). In addition,
the maximum unprotected residual capacitance (Ci) and inductance (Li) of each appa­ratus (other than the terminators) connected to the Fieldbus must be less than or equal

to:FISCO: 5 nF and 10 µH
FNICO: 5 nF and 20 µH

Appendix 1: FM-CSA Installation Drawing

The Nonincendive Field Wiring concept allows the interconnection of nonincendive eld
wiring apparatus using any of the wiring methods permitted for unclassied locations.

V

>= Voc or Vt, Ca >= Ci +C

max

The Nonincendive Field Wiring concept allows the interconnection of FM-approved

nonincendive devices with FNICO parameters not specically examined in combination

as a system when: Uo or Voc or Vt <= V

In each I.S. Fieldbus segment only one active source, normally the associated apparatus,
is allowed to provide the necessary power for the Fieldbus system. The allowed voltage
(Uo, Voc, Vt) of the associated apparatus used to supply the bus must be limited to the
range of 14 V d.c. to 24 V d.c. All other equipment connected to the bus cable has to
be passive, meaning that the apparatus is not allowed to provide energy to the system,
except to a leakage current of 50 A for each connected device. Separately powered
equipment needs a galvanic isolation to insure that the intrinsically safe Fieldbus circuit
remains passive.

The cable used to interconnect the devices needs to comply with the following parameters:
Loop resistance R': 15 ...150 /Km
Inductance per unit length L‘: 0.4…1 mH/km
Capacitance per unit length C‘: 80 ...200 nF/km

C‘ = C‘ line/line + 0.5 C‘ line/screen, if both lines are oating

or
C‘= C‘ line/line + C‘ line/screen, if the screen is connected to one line
Length of spur Cable: max. 30 m
Length of trunk cable: max. 1 Km
Length of splice: max. 1 m

Terminators
At each end of the trunk cable an approved line terminator with the following parameters
is suitable:

R = 90 ...100 Ω

C = 0 ... 2.2 µF

System evaluation

The number of passive devices like transmitters, actuators, connected to a single bus
segment is not limited due to I.S. or N.I. reasons. Furthermore, if the above rules are re­spected, the inductance and capacitance of the cable need not to be considered and will
not impair the intrinsic safety or nonincendive safety of the installation as applicable.
The sensor circuit is not infallibly galvanically isolated from the Fieldbus input circuit. Ho­wever, the galvanic isolation between the circuits is capable of withstanding a test voltage
of 500 Vac during 1 minute.

Installation Notes For FISCO and Entity Concepts:

1. The Intrinsic Safety Entity concept allows the interconnection of FM / CSA-approved
intrinsically safe devices (Div. 1 or Zone 0 or Zone1), with entity parameters not speci­cally examined in combination as a system when: Uo or Voc or Vt ≤ V
Imax, Po ≤ Pi

Ca or Co ≥ ∑Ci + ∑C

2. The Intrinsic Safety FISCO concept allows the interconnection of FM / CSA-approved
intrinsically safe devices with FISCO parameters not specically examined in
combination as a system when:

Uo or Voc or Vt ≤ V

3. Control equipment connected to the Associated Apparatus must not use or generate
more than 250 Vrms or Vdc.

4. Intrinsically Safe Installation should be in accordance with ANSI/ISA RP12.6.01
(except chapter 5 for FISCO Installations) "Installation of Intrinsically Safe Systems for

Hazardous (Classied) Locations" and the National Electrical Code® (ANSI/NFPA 70)

Sections 504 and 505.

5. The conguration of associated Apparatus must be FM Approvals or CSA Approved

under the associated concept.

6. Associated Apparatus manufacturer’s installation drawing must be followed when
installing this equipment.

7. The equipment is approved for Class I, Zone 0, applications. If connecting AEx [ib]
associated Apparatus or AEx ib I.S. Apparatus to the equipment the I.S. circuit is only
suitable for Class I, Zone 1, or Class I, Zone 2, and is not suitable for Class I, Zone 0 or

Class I, Division 1, Hazardous (Classied) Locations".

8. No revision to drawing without prior FM / CSA Approval.

9. Simple Apparatus is dened as a device that neither generates nor stores more than

1.5 V, 0.1 A or 25 mW.

10. The termination must be NRTL-approved, and the resistor must be infallible.

11. Warning:

For applications in Div. 2 or Zone 2 (Classied Locations) Explosion hazard: Except for
nonincendive eld circuits, do not disconnect the apparatus unless the area is known

to be non hazardous.

12. Warning:

Substitution of Components May Impair Safety.
