INTRODUCTION
Thank you for purchasing this product!
For installation, maintenance and assurance of a long life
of this product, please follow this manual.
CONTENT IN BOX
The product is fully assembled, and ready for installation.
SAFETY PRECAUTIONS
Only qualified personel are allowed to perform
installation and maintenance taskes to this equipment.
The junction box is equipped for termination of heat tracing
and is ready for installation when leaving the production
facilities of R. Stahl Tranberg AS. Changes made to the
product which do not confirm to the approvals of this
equipment, is a safety violation. The manufacturer is under
no circumstances responsible for personal injuries, death or
any other damage caused by such activities. Any damage
done to the equipment during transportation is not the
responsibility of R. Stahl Tranberg AS. If the content is not
complete, file a claim to the producer immediately.
MAINTENANCE/REPAIR/MODIFICATION
• Maintenance according to national regulations and
company practice.
• Before opening the junction box make sure that the
power is disconnected.
• Servicing the junction box is done be checking the in-
tactness of the junction box, gasket and glands. If nec-
essary lubricate the lid bolt threads with grease type
Renolit Unitemp 2 from Fuchs.
If repair or overhaul is necessary this may only be done with
Tranberg spare parts.
Modification of the JB or change of design are not permit-
ted, exept for installing additional glands and terminals ac-
cording to the approval of the JB.
INSTALLATION INSTRUCTIONS
Assembly of wall mounted type fig. 01
• Mount the thermostat junction box by at least 2 pcs.
M6 bolts placed diagonally on a wall or proper sup-
ported rack.
• Remove dust protection or stopping plugs and install
gland to be used. For holes not in use these must
be inserted with stopping plugs. Only certified cable
glands and blinds may be ised. Gland has to be chosen
according to cable diameter used.
• Strap the transition unit to pipe with pipestraps.
• Assembly the flexible conduit according to the spesial
gland. see fig. 2
Temperature sensor
The TEF 1060701(&TEF 1060702) delivers up to 20 Ohm
lead resistance compensation. Therefore any type of three
wire DIN IEC 751 Class B PT100 resistance temperature
devices can be used. Two temperature inputs are allocated
to the temperature controller. The third is allocated for the
temperature limiter
The sensor should be strapped in good thermal contact
with the pipe or equipment. In addition to general mechani-
cal protection, the sensor should be protected so that the
thermal insulation cannot be tapped between the sensor
and the heated surface. The sensor is normally fixed to
pipe or object by use of aluminium tape. Other methods
could be thermowells suitable for the application.
RTD connections
Sensor connections may be extended using a three core
shielded or braided cable with a maximum length of up to
150m(3x1.5 mm² minimum required). The screen or braid
of the extension cable is to be grounded at the JB end only.
Termination
In order to maintain the mode of protection, the conductors
will have to be connected with special care. The isolation
must reach up to the terminals and the conductor must not
be damaged. Termination of heat cables must be according
to cable specification given by supplier of these. Tighten all
terminals, also those vacant. Reinstall lid and tight bolts
firmly with suitable tool by hand force. Over tightening may
impair the protection category.
Connection: See last page
Communication and networking.
Tranberg PlantConnect™ Software is a Scada system for
control and monitoring of Tranberg thermal units.
TEF 1060701(TEF 1060702) units can be networked to
Tranberg PlantConnect™ Software via RS 485 serial inter-
face.
APPROVAL
PTB 09ATEX1109
The TEF 1068702 safety temperature limiter meets the re-
quirements of EN 60079-30-1. For applications installed
in a hazardous area this means that the protective device
shall de-energize the system to prevent exceeding the
maximum permissible surface temperature. In case of an
error by, or damage to the sensor, the heating system shall
be de-energized before replacing the defective equipment.
The protective device operates independently from the
temperature controller.

AREA OF USE FOR TEF 1060702
Safety temperature limiters are required in all areas
where thermal processes need to be prevented from
overheating. In case of temperature upset they will put
the system into a safe operating condition. The safety
function will invoke in the event of a fault, when the
permissible temperature limit is reached or in case a fault
occurs (such as probe break, probe short-circuit, com-
ponent failure, or supply failure) even when the process
conditions are within the permissible temperature range.
In all these cases the equipment is immediately switched
off. If the fault is no longer present, then the safety tem-
perature function must be manually reset before the unit
goes back to normal operation. The output of the unit
will only be enabled when all conditions are safe; mean-
ing that the temperature measured by the limiter RTD
has dropped below the limiter set point and when there
are no other faults being detected. In other words, the
unit will only reset after the normal operating conditions
have returned.
