A description now follows of the individual menus and
parameters which appear on the display of the device and
which can be parameterized via the operator buttons.
Parameterization of the EPT202 via the visualization software
is described in chapter 8.
The memory for date and time is retained for approx. 2 weeks
without power. After this time, these data will be lost.
When the device is connected for the first time or is powered
up after approx. 2 weeks without power, the current date and
the current time must be set. The device jumps automatically
to this menu item.
Correct functioning of the EPT202 is not ensured unless the
device is completely parameterized.
The following description of the individual menu items is
based on the order in which they appear during
parameterization. However, the menus are arranged so that
during operation the user can access the most important
menus quickly. For the menu structure, see the short
operating instructions.

Parameterization of the analog outputs
The analog outputs for the oil and the
windinging temperature are parameterized
in this menu.
For more information regarding analog
outputs, please refer to page 13 of chapter 5.3.

Recording of the ambient temperature
In this menu item the recording of the
ambient temperature can be activated. For
more information on this function, please
refer to page 13 of chapter 5.3.
Only the 4 to 20mA input can be used as an input sensor for
ambient temperature. A Pt100 sensor must be used for the
input of the Top-Oil temperature. The sensor input is then
automatically parameterized for Pt100

This menu item is used to parameterize the ratio of the CT
current transformer. The EPT202 is fed by the CT current
transformer so that it can image the load of the transformer.
The actual load current is calculated from
the current transformer ratio and the
actual CT current.

Parameterizing the hotspot factor (H)
This parameter is an empirical value with which the hotspot
temperature according toIEC354 is determined. It depends on
the size of the transformer, the short-circuit impedance as well
as other factors.
When this parameter is set to 1.0, then
according to IEC354 the average
temperature of the upper winding layer is
calculated and indicated. For calculations
according to ANSI standards, the value
must be set at 1,0 because it is not used in the calculation.
