The following table shows the various states with respect to the safety circuit and to the door bypass
safety circuit.

5 Actuate stops (by moving
again to the stops) Closed Not possible inactive
6 Normal operation Closed Possible active
As soon as all stops have been actuated, the PSU01 switches to the normal operating mode. More
detailed information on the parameters can be found in the programming manual or in the manual of a
compatible control or of the separately available programming unit.
6.3 Protected area parameterization
As delivered, the protected area (reduced shaft head / shaft pit) is always active. This means that both
inspection limit switches (top and bottom) are initially enabled (also wiring is required).
The inspection limit switches can be enabled/disabled selectively in configuration mode (see parame -
terizing manual).
The possible options are described more in detail below:

0.6 m/s Bypassing for

2 Inspection limit switch only
