Installation manual
For the V and s curves there are the following relationships without overspeed distance:
Parameter Acceleration method
t Value from PSC1 response time data
Resp
+ delay in external shutdown chain
a , a n.a.
F V
V = V + a
a1 S
For the V and s curves with overspeed distance the following applies:
Parameter Acceleration method
t Value from PSC1 response time data
Resp
+ delay in external shutdown chain
a , a n.a.
F V
V = a * t
a2 F
With its action the filter displaces upward the speed threshold set V
the application the new values for the response time (TResp = T
speed on shutdown by the PSC1 are to be taken into account.
