13 ANALOGUE
INPUTS
Settings for the analogue inputs.
13.01 AI1 FILT TIME
Defines the filter time constant for analogue input
AI1.
Note: The signal is also filtered due to the signal
interface hardware (approximately 0.25 ms time
constant). This cannot be changed by any
parameter.

0.000…30.000 s Filter time constant for AI1. 1000 = 1 s / -
13.02 AI1 MAX
Defines the maximum value for analogue input AI1.
The type is selected with jumper J1 on the JCU
control unit.
