7.1 Control unit Input I0 & Inputs and Outputs
exp. board 4583, Input 0-4
7.1.1 Not supervised
Normally open (R > 2K)
or
Normally closed (R < 2K)
Activation time: >1 sec.
Connections, see drawing 128-22.
7.1.2 Supervised
Each supervised input can be in four different states:
 Open circuit (cut-off)
 Not activated (quiescent)
 Activated
 Short-circuit
Depending on the selected logic, Normally open (high resistance) or
Normally closed (low resistance), the following table is valid.
Line resistance R
Normally open
(high resistance)
Normally closed
(low resistance)
R > 6K8
Open circuit (cut-off)
Open circuit (cut-off)
6K8 > R > 2K
(nom. 3K3)
Not activated
Activated
2K > R > 70
(nom. 680)
Activated
Not activated
R < 70

Short-circuit
7.1.2.1 Input line fault
If open circuit (cut-off) or short-circuit is detected on a supervised
input, a fault will be generated in EBL128 and the following fault
message will be displayed:
FAULT: Programmable input
alternatively
