2.1.3 Dimmer setup for analogue indicators
The figures below illustrate the different ways of arranging a local dimmer on the XL indicators.
Method 1 Method 2
Method 1 illustrates a method for dimmer connection that adds a 10 kOhm potentiometer in series with the illumination
input (terminal This method is preferred, if the consumption has to be kept low. However, it is a disadvantage that the
illumination cannot be set to total darkness.
Method 2 illustrates a method for dimmer connection that adds a 1 kOhm potentiometer as a voltage divider. This method
has the advantage that the illumination can be set to total darkness. The disadvantage is that the consumption of the
potentiometer is approximately 24 mA, even if illumination is set to total darkness.
It is also possible to use an external voltage for dimming the illumination. The regulation range from darkness to full
illumination is 7 to 30 V DC. The consumption is 30 mA at 30 V DC.
