For the V and s curves with overspeed distance the following applies:
Value from PSC1 response time data

Delay in external shutdown chain
from relay / contactor, brake
manufacturer data etc.

With its action the filter displaces upward the speed threshold set V
a
by an amount
delta_v_filter. For the application the new values for the response time (TResp = T
PSC1
+
TFilter), as well as the resulting speed on shutdown by the PSC1 are to be taken into account.
6.4 Response times when using the PSC1-E-3x
The basis for the calculation of response times is the cycle time of the PSC1. system. During
operation this is T_cycle = 8 ms. The response times stated correspond to the related
maximum propagation time within the PSC1 module for the specific application. Depending on
the application, further application-dependent response times for the sensors and actuators
used must be included in the calculation to obtain the total propagation time.
Worst-case delay, input in the
basic module to the PAE
E.g. activation of a monitoring function by an
input signal in the
basic module
Worst-case delay, input PSC1-E-
31 to the PAE in basic module
E.g. activation of a monitoring function by an
input signal in the expansion module PSC1-E-31
Processing time PAE to PAA in
basic module
Shutdown by a monitoring function or by
an input in the PAE
Activation / deactivation of digital
output in basic module from PAA
Activation or deactivation of an output in
the basic module after change in the PAA
Activation / deactivation of digital
output in expansion module via
PAA on basic module
Activation or deactivation of an output in
the expansion module PSC1-E-31 after
change in the PAA in the basic module
