A) Description
The shaft houses the following sensors:
•
Two timing devices (SRD, SRS) for the end floor speed change, toggle contacts
SRS also identifies the unblock zone of the lower end floor for emergency descents
•
A monostable contact (SIM) for the floor zone information and encoder count check
•
A monostable contact (SIZ) for the control of the second safety circuit channel; it uses the
same magnet as the SIM sensor
•
Incremental encoder installed on the roof of the cab for speed change control, electronic
valve speed measurement, floor stop, and doors open/closed detection
The floor area, understood to be the space above and below the floor where it is possible to
perform detection with the doors open, is defined by a magnetic strip that works with the SIM and
SIZ sensors.
B) Installation
1.
Mount the two bracketed shaft impulse generator kits (p/n PIV01 and PIV02) on the roof of
the cab as shown in the schematic diagram Dia. 2.8.4.1 shown below.
