4.3 Safety features
4.3.1 Sensitive edges
The sensitive edge is a device that stops the running of the plant system and is located on the
edges of the flooring. In the event that a person or an object is located in an excessively external
position and therefore not suitable for safety, the running is stopped and on the display the symbol
for “safety stop” appears, until the obstacle on the edge of the platform is removed.
4.3.2 Photocells
The operation of the photocells is connected to the presence of an obstacle placed between the two
installation points of these devices. In this case the safety function is activated, which stops the
plant system and on the display the symbol for “safety stop” appears. To restart the running of the
platform it is sufficient to remove the obstacle and hold down the command button.
4.3.3 Safety optical sensors (only for versions with photoelectric sensors)
The platform lift is equipped with safety photoelectric sensors to prevent against crushing hazards.
While the platform is moving, if the sensor beam is interrupted by an obstacle, it will immediately
stop and the STOP signal will appear on the display. This signal will remain active until the obstacle
is removed (if the machine is not aligned with a floor, the siren will also sound intermittently). To
verify that there is an object obstructing the beam, pass your arm through the sensor and check if
the STOP signal disappears. If the signal remains, verify the presence of other obstacles (carefully
also checking edges) and the emergency button status (must not be pressed). If the signal does not
disappear, contact service assistance.
4.3.4 Overload
If on the display the “Overload” symbol appears (see page 4) or, for the versions without display,
the overload signal lights up (see figure), the platform cannot move. Totally remove all loads from
the platform. Only after the overload signal disappears is it possible to again use the platform.
4.3.5 Motor overload
In case of a motor overload, signalled to the user by way of the red floor LED flashing and the
lighting of the emergency warning lamp on the button panel. The platform may, in any case,
descend.
