Basic function principles
The analog input terminals KL3001 and KL3002 process signals in the range between -10 V and +10 V with
a resolution of 12 bits (4095 increments). The terminal inputs are differential inputs with common ground.
Due to the differential inputs, the terminals are particularly suitable for measuring earth free voltage drops.
Cross-currents caused by voltage differences at the input terminals do not lead to any appreciable
measurement distortion up to a difference in potential of 35 V (U
The green Run LEDs indicate the operating state of the associated terminal channel.
• On: Normal operation
• Off: Watchdog-timer overflow has occurred. If no process data are transmitted by the Bus Coupler for
100 ms, the green LEDs go out.
Process data output format
In the delivery state the process data are shown in two's complement form (integer -1 corresponds to
0xFFFF). Other presentation types can be selected via the feature register (R32) [} 37] (e.g. signed amount
representation, Siemens output format).
