Figure 3: QUASAR T25 A3 Governor
The protection of this system against UCM is as follows: The D-Box electronic system compares, at all times, the
status of the car doors and the floor level via input signals from the installation. These signals are:
Doors closed.
Floor level,
Motor contactor
N.B.: Please check the electrical characteristics in the D-Box manual in order to verify the voltage of the signals to
be entered.
By using these inputs, if the D-Box detects that the car leaves door level with doors open, the contactor in the safety
line is activated, which causes the QUASAR T25 A3 governor’s parking system coil to de-energise. This will make
the parking system interlocking system operate on the governor’s centrifugal systems, thus causing the governor to
interlock.
Since the movement of the interlocking system is linked to the operating driving bar, when the governor interlocks,
the driving bar will operate on the safety gears thus causing them to jam and the car to brake.
