6.4 Teaching the top limit switch with reduced shaft head
In the case of reduced shaft heads, where the top limit switch position cannot be reached on the car,
proceed as follows:
Position the elevator car exactly 1,500 mm underneath the required limit switch position. With a spe-
cial instruction (see parameterizing manual), the PSU01 saves the position temporarily as a tempo-
rary limit switch. E.g. if the installer is at position 10,000 mm, the top limit switch is assumed to be at
11,500 mm. It is not active yet, and the state does not change.
If the elevator stops within 15 minutes at (or above) this calculated position, this calculated position
(not the current position) is accepted as the top limit switch and the system switches automatically to
he next state (see parameterizing manual).
6.5 Time-delayed limit switch parameterization
At the beginning, both time-delayed limit switches are disabled until the teaching of the limit switch
positions.
For detailed information on the configuration of the time-delayed limit switches, please refer to the
parameterizing manual.
The inspection limit switches are fixed at their position at a distance of
1.2 m from the top limit switch for the top inspection limit switch and
1.2 m from the bottom limit switch for the bottom inspection limit switch.
The positions of the inspection limit switches cannot be modified.
When the inspection is wired, the speed during inspection is limited to
0.6 l/s. If this speed is exceeded, the „overspeed" function trips and the
safety circuit opens until the elevator has stopped.
As soon as the limit switches have been taught, the time-delayed limit
switches are identical with these, but a travel faster than 1 m/s is pre-
vented (by the opening of the safety circuit).
This state remains active until the time-delayed limit switches have
been explicitly taught in.
