Fig. 3: Static application switching
Example: application 1 → application 2 →
application 3
1: IN1 = 0 → 1 → 0
2: IN2 = 0 → 0 → 1
3: ready output
4: trigger input
A: trigger enabled
B: trigger disabled
5: ID number of the active application
The figure shows the PNP output logic (factory setting). The behaviour of the NPN output logic
is the opposite of that of the PNP output logic.
PNP output logic: In case of a high signal (1), voltage is applied.
NPN output logic: In case of a low signal (0), voltage is applied.
To change the factory setting:

For application switching the monitoring time t
R
and the trigger disable time t
P
have to be taken into
consideration.
•
Monitoring time t
R
:
Application switching only starts when the state at both switching inputs remains stable for 20 ms
after an edge change.
•
Trigger disable time t
P
:
The trigger input is disabled during application switching. The disable time depends on the
following factors:
– the number of applications on the unit
– the number of models in the application to be activated.

Fig. 4: Pulse-controlled application switching
1: gate signal, IN1 = 0 → 1 → 0 (t

= signal active)
2: pulse signal, IN2 or trigger input = 0 → 5 pulses → 0
3: ready output
The figure shows the PNP output logic (factory setting). The behaviour of the NPN output logic
is the opposite of that of the PNP output logic.
PNP output logic: In case of a high signal (1), voltage is applied.
NPN output logic: In case of a low signal (0), voltage is applied.
To change the factory setting:

.
While there is an active signal on switching input IN1 (gate signal), the unit counts incoming pulses
and activates the respective application.
