2.4.5 Elevator Car Wiring

All elevator car wiring is detailed on the wiring schematics and connection diagrams including the wiring
to the car station, door operator, car top selector, and inspection station. The number of required
traveling cable conductors is listed in the connection diagrams. A job specific "pull sheet" is also
included in the connection diagrams.

2.4.6 Machine Room Wiring

All machine room wiring is detailed on the wiring schematics and connection diagrams including the
main power supply wiring, motor wiring, and field wiring

2.5 Normal and Top Terminal Slowdown Limits

The terminal slowdown limits include the Normal Terminal Slowdown Limits (including UN, UT, DN and
DT) and the Top Terminal Limits (including TSD and TLH). The Normal Terminal Slowdown Limits are
read from absolute positions on an encoded tape. The TSD and TLH limits are mechanical switches.
The Normal Terminal Limits are used to cause the car to slowdown and stop at or near the terminal
landing if the normal stopping means does not function properly. The NTS processor monitors the
position of the car in the hoistway from the APS selector camera and turns off the appropriate limit
switch, when the limit position is reached, independent of the Main CPU.
The Top Terminal Slowdown limits are used to prevent the car from hitting the stop ring on the hydraulic
jack at a speed greater 50 fpm. TSD and TLH limits must be mechanical switches installed on all
GALaxy eHydro controlled elevators and must be set to activate mechanically from the movement of the
car.
The distance that the limits are placed from the terminal landing depends on the speed of the car. Table
2-0 shows the slowdown limit locations with respect to contract speed. All distances are shown in
inches. The distances listed represent the distance from the terminal landing when the slowdown switch
is actuated.
