In the event of an electrical power supply failure, this device
will automatically engage and bring the escalator to a smooth stop. This device is located on the drive unit of the upper truss.
This device will engage immediately upon elongation or
breakage of the step chain and bring the escalator to a smooth stop. This device is located at the lower side of the machine room.
This device will automatically engage and brind the
escalator to a smooth stop, when fingers, ands, or other objects are detected at the handrail inlet into the newel
In the event the escalator steps are upthrust in parts,
this device automatically engages and brings the escalator to a smooth stop. This switch is located at the right and left side of both the upper and lower truss.
When elongation or breakage of the drive chain occur, this
device will automatically disconnect the power supply to the drive unit causing the escalator to come to a smooth stop..
Activation of this button will automatically disconnect the
power supply to the drive unit and engage the electromagnetic brake bringing the escalator to a smooth stop. This button is covered with a movable transparent cover and located on the right side newel facing
the escalator at both the upper and lower landing. When the cover is moved, a buzz is activated.
When objects become trapped between the steps and the
skirt guard, this device will automatically brin the escalator to a smooth stop. This switch is located at the right and left side of both the upper and lower truss.
If the escalator motor overload or short-circuit, this
device will automatically disconnect the power supply to the drive motor brining the escalator to a smooth stop. This device is located in the machine room.
