8.3. Additional Safety Sensors
Balance sensors will stop the Lift Car if a problem exists with
either of the lift ropes.
Overload sensors will determine whether the lift is overloaded
prior to moving. To notify the user that the lift is overloaded, the
related area on the control panel inside the cabin will flash. (See
page 10).
The Slack Rope sensor detects if the lift ropes are slack and will
prevent the lift car from attempting to travel any further. In the
unlikely event that the regular limit switches should fail, there are
auxiliary switches located above and beneath the Lift Car. If those
should fail at the same time, there are further back up switches
that will stop the lift in an emergency. Once those emergency
stops are activated, the lift will stop until the incident has been
investigated by a service technician, and the problem has been
corrected.
The lift is equipped with an emergency stop button. Pressing the
red emergency stop button while travelling in the lift will stop the
lift immediately and trigger the alarm. Therefore, this button
should only be used in extreme situations; such as the lift failing
to stop when the control button is released. The emergency
system must be reset once the cause of the incident has been
resolved. A key switch prevents operation while the
lift is in “off”
mode. This switch also resets the controls after an emergency
stop.
In the event of any rope related issues, an integrated brake system will stop the lift. The safety brake stops the lift
immediately in the unlikely event of a hoist rope failure. If any of these safety features are activated, they must be
disengaged and reset by a Lifton service technician.
In the event of a power failure occurring whilst the lift is in operation, the lift is fitted with an emergency power supply
and emergency lights that come on automatically. The lift can be moved to the lower floor on emergency power by
using the normal lift controls. The raise control is then ineffective. All safety features also remain fully operational
during lowering on emergency power.
Note; the main power switch in the ceiling of the lift must not be turned off with the intention to save electricity. The
lift only draws electricity like a kitchen appliance. Turning the main power switch off will activate the battery back-up
system and drain the battery if used unnecessarily. A flat battery will prevent operation of the lift.
8.6. Emergency Evacuation Procedure
8.6.1.
When main power is lost, during travel, after a short delay the lift cab lights in the ceiling will illuminate.
8.6.2.
If the emergency stop button is used, the C.O.P. will need to be reset before the lift can be moved
downwards.
8.6.3.
Turn ‘
off
’ the emergency stop button by twisting the button (it will pop outwards), to eliminate horn.
