Note:

Due to the characteristics of the 1…10 V interface, the following must
be noted:

All control lines of an ECG installation must be connected with the
right polarity (+/-)

The control line is voltage-insulated from the mains line but there is
no safety extra-low voltage (SELV). Therefore, cables and terminals
that are approved for supply voltage 230V must be used for the
installation

The control voltage is simple to limit upwards or downwards with
resistors; several control units can be combined with one another

The correct function of the ECG can be tested as follows:

Switch-on of the ECG with open control line. The lamp must

ignite and burn with max. luminous flux

Switch-on of the ECG with shorted control line (wire jumper).

The lamp must burn with min. luminous flux

Each OSRAM DIM ECG can be used as a normally non-dimmable
ECG if there is no control unit connected to the control line

The dimmable ECGs are only dimmed via the 1…10 V interface
and switched via the mains line

The maximum load capacity of the control unit (switched output
and 1…10 V output) must be heeded

The connected control unit must always be able to handle the cur-
rent supplied in the control line by the ECG (current sink) and to
reduce the control voltage. This precept is fulfilled by according-
ly dimensioned potentiometers as well as by all OSRAM control
components. Normal power supplies, converter boards etc. do not
necessarily have this characteristic! To check, connect the control
unit, set to the lowest brightness and measure the voltage on the
control line. The set value is 1V or less

OSRAM DIM ECGs cannot be dimmed via the mains line (e.g. with
phase control mode, round control pulses etc.)
