— It is possible to test if the ECG is working properly as
follows:
— Switching on the ECG with open control line. The
lamp must ignite and burn at maximum luminous
fl u x .
— Short-circuiting the control line (wire jumper). The
lamp must burn at minimum brightness.
— Each OSRAM DIM ECG can be used as a normal, non-
dimmable ECG if a control unit is not connected to the
control line.
— The dimmable ECGs are only dimmed via the 1…10-V
interface; switching is executed via the mains cable.
— The maximum capacity of the control unit (switch output
and 1…10-V output) must be observed.
— The respective connected control unit must be in the
position to absorb the current delivered by the ECGs in-
to the control line (current sink) and minimize the control
voltage. This requirement is fulfi lled by the potentiome-
ters, which are dimensioned accordingly, and all
OSRAM control components. Normal power supplies,
converter cards etc. do not necessarily have this prop-
erty. For screening, connect the control unit, adjust to
the lowest brightness and measure the voltage of the
control line. The setpoint is 1 V or less.
— OSRAM DIM ECGs can not be dimmed via the mains
cable (e.g. with phase alignment, ripple control pulses,
or similar methods).
2.7.1 The 1…10-V dimming curve
The 1…10-V interface is defi ned in the IEC 60929. Within
the control voltage range of 3 V to 10 V, there is a largely lin-
ear correlation to the relative luminous fl ux. The logarithmic
behavior (analog to the DALI devices) is simulated in the
1…10-V interface through a logarithmic potentiometer.
With the 1…10-V interface, the control current decreases
as the control voltage increases.
