Method for adjusting at least one operating parameter of an operating unit for electric lamps

A method for adjusting at least one operating parameter of an operating unit for electric lamps, the operating unit (EVG) having a voltage transformer (WR) with at least one load circuit (LD, C) connected thereto, a microcontroller (MC) for driving the voltage transformer (WR), and terminals (j1, j2) for at least one lamp, wherein the method has the following steps:

• a) operating the operating unit (EVG) with a calibrated load which is connected into the load circuit (LD, C) and connected to the terminals (j1, j2),
• b) transmitting at least one control command (1) to the operating unit (EVG), which causes the operating unit (EVG) to set a specific operating state, and which starts the adjusting method for the at least one operating parameter,
• c) detecting the actual value (3) of the at least one operating parameter,
• d) comparing the actual value (3) of the at least one operating parameter with a prescribed desired value (6) of the at least one operating parameter,
• e) determining and storing a correction value or desired value (5), dependent on the desired value/actual value comparison, for at least one drive parameter, which is stored in the operating unit and determines the driving of the voltage transformer (WR),
• f) driving the voltage transformer (WR) by using the determined correction value or desired value (5), stored in the operating unit (EVG), of the drive parameter, and
• g) repeating steps c) to f) if the actual value (3) of the at least one operating parameter deviates from its desired value (6) by more than a prescribed absolute value;
• wherein the method is carried out with the aid of an external process control device (P) which is connected to the microcontroller (MC) via an external interface of the operating unit (EVG) during the adjusting method, and generates the at least one control command (1) for the operating unit (EVG);
• and
• wherein the actual value (3) of the at least one operating parameter is fed to the external process control device (P).

• wherein the method is performed on a dimmable operating unit, the first operating parameter being the output voltage or output power of the operating unit (EVG) in the case of a minimum dimming setting, and a second of the at least one operating parameter being the output voltage or output power of the operating unit (EVG) in the case of a maximum dimming setting.
