CONFIGURATION AND SET-UP

5.1.

Introduction

The configuration of the ETL equipment including AF interfaces and
teleprotection has to be done according to document 'Programming
and Testing Instructions for the ETL600 Rel.1 Equipment'. The two
major steps of the procedure are: Programming and Testing. Each of
these steps consists of a number of substeps with associated
instructions listed in the document. Each substep is documented in a
report to be filled out during the procedure. Templates for these
reports – one for programming and one for testing - are included in the
document. These reports should be kept for reference as long as the
equipment is in use.
Hardware programming is made by inserting or removing jumpers
while the equipment is unpowered. After the equipment is powered up,
software settings are entered via the HMI600 menu 'Configuration'.
Usually these settings are saved to a file, which is downloaded to the
equipment later during testing of the system.
Note:
Testing is done with the equipment powered, and all test procedures
are supported by HMI600, menu 'Equipment / Tuning and Testing'.

System levels and level settings

The level of the RF output signal generated by the ETL equipment is
given by the AF signals applied to the active input ports of the ETL as
well as some settings like nominal RF output power. For a successful
operation of the system, it is important to correctly determine the levels
of the AF signals applied to the active input ports and to enter these
levels into the HMI600 for configuration of the system. In the ETL as it
is tradition for PLC systems, signal levels are specified in logarithmic
units such as dB, dBm, dBr, dBu, dBm0, dBm0p which are explained
in the following sections. The definitions are roughly consistent with
those given in IEC 60495, but due to the digital signal processing used
extensively in the ETL600, some extensions and deviations have been
necessary.
Configuration and Set-up
1KHW001489-EN
The configuration download operation will only be
successful when the system components (including
the HMI600 program) are compatible . To verify this,
refer to document 'Compatibility Requirements for
ETL600'. In case of uncertainty, use the newest
available HMI600 version.
