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 6)
.
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 these should fail at the same time,
there are further back up switches that will
stop the lift in an emergency. Once these
emergency stops are activated, the lift will
stop until the incident has been investigated
by a service technician, and the problem has
been corrected.
Emergency Features
The lift is equipped with an emergency stop
button. Pressing the red emergency stop
button whilst 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.
