Fig. 2: Application example
Via acyclic parameter setting, the following properties can be set for the LEDs:
•
Direction of movement (from bottom to top or from top to bottom)
•
Level thresholds per LED (a maximum of 20 thresholds between 0 and 100 in ascending order)
When the threshold is exceeded, the corresponding LED is activated.
•
Colours of the 20 individual LEDs (20 different colours each or off)
•
Colours of the 20 LEDs (3 user-specific combinations with a maximum of 20 colours each)
•
Frequency per LED (permanently on, flashing slow/medium/fast, blinking slow/medium/fast)
•
Display range (all LEDs, individual LEDs, top LED only)
•
Brightness (0...100 %)
For the models with an acoustic signal device the audibility of the buzzer can be set (0…100 %).

8.3 User-specific colour combinations
In both Signal Light Mode and Level Meter Mode, the LEDs are controlled according to the process
data.
Independently of this, the user has the option of defining three different colour combinations (User
preference color Bank 1, Bank 2 and Bank 3).
