The better these recommendations are implemented, the more stable
is the light at the lowest dimmer setting, even with a very small lamp
spacing – and, hence, the full temperature range of the ECGs can be
used.

In the "worst case" twist the cables of the heating circuits together,
hence ensuring they lie close together. With 1-lamp ECGs these
are the 21-22 and 26-27 cables, with 2-lamp ECGs; 21-22 and
21-23, 24-25 and 26-27. This is particularly important if adjacent
ECGs are operated at the lowest dimmer setting (1(3)%).

If there still are problems: Remove all lamps except for the most
"problematic" ECG – this will eliminate possible faults from the other
lamps. If the lamp then works correctly over the entire dimming range,
the decoupling measures for the other lamps (cables) are still not ad-
equate.

Figure 6: Three 1-lamp ECGs

Correct: Wrong:

The lamp lines are laid close to
the respective lamps.
There are no overlapping lamp
current circuits. The “hot" side
is up and the “cold" is down.

The lamp lines of all ECGs are laid
together, also overlapping lamp
current circuits are formed in this
way.
