Final Tasks; Practical Advice - ESYLUX POWERLINE-SYSTEM EPL Manual De Instrucciones

4.3 Re-programming
• The group assignment can be easily changed at a later stage at the rotary knobs.
In doing so, the EPL modules must not be disconnected from the power supply or reset.
• A reset should only be carried out if an EPL module needs to be programmed for
another domain. Press and hold the Reset button for around 6 s. The Conf. LED will then
flicker briefly. A few seconds after releasing the Reset button, the Conf. LED will flash
regularly, indicating that the EPL module has been reset to the default setting.
• Continue by following the instructions under Point 4.1 Initial Activation or Point 4.2 Extension
of an Existing Domain.
4.4 Final Tasks
• Close all switch and junction boxes.
• Carry out a functional test and check the group assignments against the programming
table.
5 • PRACTICAL ADVICE
The 230 V supply was not originally intended for data transmission and can therefore
attenuate the signals of EPL modules.
The ESYLUX POWERLINE-System EPL is designed to work reliably even in the case of
large-scale attenuation in the 230 V supply.
If, however, several EPL modules are unable to communicate with each other, you have
the following options:
• If all Conf. LEDs go out when the Prog. button is pressed, check that rotary knobs "g" and
"e" are set to the correct position. All EPL modules assigned to each other must belong
to the same respective group "g" and "e" (see Point 4.1 Activation/Programming).
• If several Conf. LEDs continue to flash once the Prog. button has been pressed, proceed
sas follows:
- Check that any EBs and electronic transformers present are connected properly.
Experience has shown that the incorrect installation of these devices can cause
interference. Follow the relevant installation instructions.
- Place the EPL modules that are not connecting with each other, on the same
phase/phase conductor by re-wiring in the distribution board.
- Install phase couplers if the re-wiring outlined above is not possible.
- For each phase/phase conductor, fit a band-stop filter in the supply line to the EPL
installation area in order to prevent external interference.
