Description
Select the safety function that the safety option
activates when the safe input is active.
[0] STO - the safety option activates STO.
[5] Disable - the safety option ignores the current
safe input.
[8] SO Mon - the safety option monitors all activity
on the current safe input, but does not activate
safety functions. The safety option transmits the
information to the PLC and the PLC handles the
safety logic.
This parameter is an array with 2 elements.
Element 0 contains DI1 settings and element 1 -
DI2 settings.
Select the safe input type.
•
[0] NCNC: A digital input is active when there
is 0 V at both channels of the input.
•
[1] Antivalent: Adigital input is active only
when there is 0 V at channel A and 24 V at
channel B.
•
[2] NC: The functionality is similar to NCNC.
For more information, see chapter 3.2.1 Permitted
Sensor Types on Digital Inputs.
Enter the maximum time in ms allowed for
differences between input channels. This
parameter helps to prevent errors caused by
temporary discrepancy.
Enter the stable signal time in ms. The stable
signal time is the period where the Safety Option
MCB 152 suppresses temporary signal changes at
its safety inputs. This functionality prevents the
Safety Option MCB 152 from reacting to short test
pulses from external modules or sensors.
Select whether the safety option restarts automat-
ically or waits for a manual reset after the safety
function was activated via a digital input.
[0] Manual - when the safety function is activated
via a safe input, the safety option requires a reset
from a reset source before it can run again.
[1] Automatic - when the safety function is
activated, the safety option can run again as soon
as the condition that triggered the safety function
ceases.
