Two different function types are possible with the variants 33PS02, 33PS03, 33PS05. The function type is selected via inputs I11 and I21.

Function 1 Function 2
I11 and I21 not connected I11 and I21 connected
Standstill monitoring is constantly active. Standstill monitoring is not active.
Close the enabling contacts when the drive is at a standstill. Enable contacts are closed (with 33PS05 only the enable contact 13/14 remains closed.
The enable contact 23/24 switches off on movement).
- The error detection "wire breakage and "single-channel" is inactive. (not with 33PS05)
