User manual of EC160 elevator intelligent integrated machine Installation and wiring

For the elevators with different speed, install forced deceleration switch. Generally, install SDS1
and SUS1 for the elevator with speed less than 1.75m/s; install SDS2 and SUS2 for the elevator
with speed of 2.0m/s~3.0m/s (in order to avoid shock, bitable magnetic switch is recommended).
The installation position in Figure 4-5 means the distance between the car and the leveling when
the switch action is valid. Install up leveling switch SUDZ and down leveling switch SDDZ on the
top of the car for the elevator with releveling. The three switches are installed vertically and SMDZ
is in the middle. When the car is leveling accurately, the plate is located at three leveling switches.
Install a SDL and SDFL on the top floor; install a SUL and SUFL on the ground floor.

See the table below for the switch installation distance. For the switch installation manner, refer to
Figure 4-10. During commissioning, adjust according to the operator.

Note the plugging depth of the plate to the standard line when applying
magnetic switch for SMDZ.
The NO/NC state of the leveling switch can be changed through
modifying the input logic of the controller.
Do not drop conductive matters into the controller; otherwise, fire or
damage to the controller may occur.
For the position of the low speed forced deceleration switch, the
elevator should act at the terminal stop and not act at the non-terminal
