System Features

1. Digital display function with boost signal: the numbers "2, 3, 4, 5" represent "fast up, fast down, slow up, slow down" respectively, and the number "0" means stop.

2. The Chinese character display function of the lifting command: the entire display screen has "maintenance, emergency stop" (plus the level signal and the display function of the selected lifting level).

3. Signal memory function: It can store the signals sent three times before.

4. Emergency stop alarm function and emergency stop extension function, with the interface of emergency stop signal and winch safety circuit blocking.

5. Blocking function between signals: when one of the signals is sent, the other signals cannot be sent.

6. The locking function between the levels of the multi-level signal, when the multi-level is lifted, only the selected level can send the lift signal, other levels cannot send the lift signal, only the stop signal and the emergency stop signal can be sent.

7. The blocking function of the signal and the driving circuit: if the signal is not sent to the garage, the winch cannot be started.

8. The memory function of increasing times.

9. There is a sound alarm function of the same number of times as the signal display. For example, when the signal "2" is sent out, there will be two automatic dotting sounds.

10. PLC can automatically scan and detect the signal system.

11. There is a voice communication function that the car room directly connects to the wellhead and the wellhead directly connects to the underground well.

12. The signal system has an interface with the signal system for people and vehicles, and the signal worker can send drive and stop signals anywhere along the hoisting line; and can communicate with the winch room.
