SIDOOR ATD410W/ATD420W/ATD430W
Input 0 to input 4 are not assigned functions on control units with a fieldbus connection in the
factory state. Parameter assignment is performed with the free function blocks (FBLOCK)
(Page 71).
Note
Input 1 is isolated from input 0, input 2, input 3 and input 4. Therefore, input 1 can be
connected independently of input 0, input 2, input 3 and input 4 as follows:
1. Connection to the internal 24 V control voltage (see figure c below.)
2. Connection to the same or a different external control voltage as input 0, input 2, input 3
and input 4 (see figures b and d below.)
