Safety
1.1
Safety instructions
All personnel involved in installation, commissioning,
operation or maintenance of this equipment must:
- be suitably qualified and
- strictly observe these operating instructions.
Improper operation or misuse can lead to
- serious or fatal injury,
- damage to the equipment and other property of the user
- a reduction in the efficiency of the equipment.
Safety instructions in this manual are presented in three
different forms to emphasize important information.
WARNING
This information indicates particular danger to life and
health. Disregarding such a warning can lead to serious or
fatal injury.
CAUTION
This information indicates particular danger to the
equipment or other property of the user. Serious or
fatal injury cannot be excluded.
NOTE
These notes give important information on a certain issue.
1.2
Specified application
The ZT-F2.1 transformer temperature transmitter can only be
used in conjunction with a TRASY2 series dial thermometer
or without thermometer in conjunction with a replacement
sensor (accessory). It is used to present the hot-spot
temperature in the transformer. It is important to read
and observe the limit values for operation indicated on
the nameplate and in the operating instructions prior to
commissioning the device.
1.3
Important notes on equipment operation
The user is advised to strictly comply with the national acci-
dent prevention regulations.
It is especially emphasized that work on active or live compo-
nents is only permissible while these components are either
de-energized or protected against direct contact.
Electrical installation is subject to the relevant national safety
regulations. It is imperative to connect the grounding cable in
order to ensure trouble-free operation.

CAUTION
Installation, electrical connection, commissioning, and
maintenance of the device may only be carried out by
qualified, skilled personnel and only in accordance with
these operating instructions.
It is the responsibility of the user to make sure that the
device is used for the specified application only.
For safety reasons, any unauthorized and improperly
executed work, i.e. installation, modification, alteration of
the equipment, electrical connection, or commissioning
of the equipment, is forbidden without first consulting
Messko!
WARNING
All relevant fire protection regulations must be strictly
observed.
CAUTION
Since measuring instruments are sensitive, all parts should
be protected against falling and knocks and vibration.
Make sure that the maximum ambient temperature of
is
85° C
not exceeded.
The ZT-F2.1 transformer temperature transmitter cannot
bear your weight.

Product specification
The ZT-F2.1 transformer temperature transmitter can only be
used in conjunction with a TRASY2 series dial thermometer
or without thermometer in conjunction with a replacement
sensor (accessory). It is used to present the hot-spot tempera-
ture in the transformer. The winding temperature is measured
indirectly. The temperature gradient between the winding
(hot-spot) and the coolant is dependent on the current in the
winding: the measuring transformer's secondary current is
proportional to the current in the winding of the transfor-
mer. The measuring transformer's secondary current supplies
a heating resistor in the ZT-F2.1 transformer temperature
transmitter. This causes an indicator increase corresponding to
the transformer load (i.e., hot-spot temperature) in the actually
measured oil temperature.
The winding temperature is simulated in the ZT-F2.1. The gra-
dient of the hot-spot temperature to the temperature of the
uppermost layer of oil at nominal load is set by DIP switches.
The winding temperature is displayed mechanically on a dial
thermometer, the temperature detector of which is incorpo-
rated in the ZT-F2.1 or which without thermometer is only
