C Commissioning Instructions for the ETL600 Rel.1 Equipment
C.1 General
Most of the commissioning tests (including fully automatic equalization) for the ETL600 system can
be done with the help of PC based software HMI600. It is assumed, that all assembled Tx filters
and Rx filter are tuned. Under normal conditions only level adjustments will be done during
commissioning. It is required to work through the document ‘Programming and Testing
Instructions’, 1KHW001493, which is dispatched along with the equipment, before starting the
commissioning.
In case of some adjustments like Tx RF level, Rx RF level etc. the permissible limits are calculated
by the HMI600 and displayed in the dialog boxes.
The pilot signal is QPSK modulated to accommodate both Signalling and Embedded Operations
Channel. As a result, the level of the pilot signal changes continuously (by about 3 dB) due to
which its exact level cannot be measured.
The equipment must be tested using a standard cable impedance or in local loop mode before
connecting the equipment via the coupling device to the power line.
The local loop can be established or interrupted with the following operation:
Establish local loop
Remove hybrid P3LE, insert dummy load P3LK and wait
until Link Alarm disappears.
Interrupt local loop
Remove dummy load P3LK.
Return to normal operation
Remove dummy load P3LK, insert hybrid P3LE and
connect RF-cable to X175 at P1LA.
)
Note: After plugging in the dummy load P3LK, wait until Link Alarm disappears.
Caution
Activating a Tuning tone, simulating alarms, get the equipment to local loop
operation, etc. disturbs the link.
C.1.1 Checking the line of communication
It is essential that the behaviour and characteristics of the line of communication between the sets
of PLC terminal equipment be checked as described in the instruction manual, 1KHW001489,
chapter 7, 'Commissioning'.
C.1.2 Visual checks before switching ON the equipment.
DANGER
Check the wiring of protective earth to the equipment. Check, if a
protective earth wire of at least 25 mm
2
has been connected visibly to
the earth bolt of the cubicle.
Caution
Check power supply polarity and voltage.
In case of an AC supply, jumpers, located inside of B5LC, had to be set, see
document ‘Instruction for changing the input voltage of B5LC’, 1KHL015788.
In case of battery supply: Check if the positive pole (+) of the battery is grounded. If it is, place an
earth jumper to the positive pole of the cubicle supply.

Note: Switch the equipment ON now.
