Installation manual of system “bp408” - Commissioning 103
8.11.1 Installing the delay switch
WARNING!
For your own safety, the inspection control ON-OFF and the UP-DOWN keys and
the emergency stop switch must be wired into the safety circuit as specified in the
circuit diagram. To perform the first drives when the absolute encoder is not
installed, the delay switches S81 and S82 must be in the end stops for the
inspection drive and the return drive at the correct deceleration points
The deceleration in the end floors is initiated when the switches of the direction of
travel correspondingly open. The delay switch S81 opens and decelerates for the
upper end stop. The delay switch S82 opens and decelerates for the upper end
stop. The speed of the inspection and return control must be switched off at these
deceleration points. The levelling position of the end stop may not be overrun.
Make the following settings in the service menu:
> MAINTENANCE
> MAINTENANCE FUNCTIONS
Scroll down to the function in this category
> ACTIVATE ASSEMBLY DRIVE
and select ON. Now, continue to scroll to
>
ASSEMBLY DRIVE WITH PRE-LIMIT SWITCHES
(S81/S82) and select

.
Now you can perform the first drive via
inspection/return to install the absolute encoder
system as described in chapter 6.6.
