Potentiometer for time setting
Potentiometer for infinite time setting of the time-delayed enabling circuits on the Advanced
basic units (with time-delayed enabling circuits).
● 3SK112.-.CB41 setting range: 0.05 ... 3 s
● 3SK112.-.CB42 setting range: 0.5 ... 30 s
● 3SK112.-.CB44 setting range: 5 ... 300 s
Note
The delay time ends when the voltage is disconnected. The time-delayed contacts change
switch position.
Parameterizing "without cross-circuit detection":
If "without cross-circuit detection" is set on the device, inputs IN1 and IN2 are not checked
for cross-circuits. Inputs IN1 and IN2 then no longer have to be supplied from clock outputs
T1 or T2, but can also be supplied from a + 24 V DC signal, for example, from the same
current source from which the device is supplied.
The clock outputs are never switched off, because they are also required for the PAR and
INF inputs.
Note
Observe the following during commissioning of the 3SK1 Advanced safety relays:
The cascading input must be jumpered if it is not to be used.
Monitoring of the feedback circuits is not optional.
