Configurable functions
4.5.1 Input delay
If the control device via which you switch the static control inputs cannot switch within
10 ms to the related input condition (e.g. due to switch bounce times), you must configure
a
n input delay. For the input delay choose the time in which your defined control device
can switch to a corresponding input condition.
The following figures, based on experience, give input delays for various methods of
switching:
Switching method Input delay required
Electronic switching using controller or
complementary electronic outputs with
0 to 10 ms bounce time
10 ms
Contact (relay) controls 30-150 ms
Control using independent sensors 130-480 ms
Also pay attention to the notes in section 5.6 “Time for monitoring case switching” on
page 71.
4.5.2 Sampling for the static control inputs
If you are using static sampling, decide between complementary or 1<of<n sampling depen-
ding on the control features available. Depending on this selection you can define the
switching criteria for the monitoring cases (see section 4.10.1 “Monitoring case switching
via static input information” on page 48).
Complementary sampling
One control input comprises two connections. For correct switching one connection must
be inverted in relation to the other.
The following table shows the levels that must be present at the connections for the con-
trol input to define the logical input state 1 and 0 at the related control input.
A1 A2 Logical input state
1 0 0
0 1 1
1 1 Error
0 0 Error
1-of-n sampling
With 1-of-n sampling you use the single connections of the control input pairs.
A1 A2 B1 B2 Result (e.g. monitoring case no.)
1 0 0 0 1
0 1 0 0 2
0 0 1 0 3
0 0 0 1 4
0 0 0 0 Error
1 1 0 0 Error
 All connections must be connected.
 Only one connection is ever allowed to be 1.
