elevator Outbound call display board BLT GPCS1152 OCAL-08 for MPK708C elevator Indicator vertical PCB panel

LOP stands for Landing Operating Panel. The LOP is the control panel located outside the elevator car on each floor of the building. The LOP allows passengers to call the elevator to their floor, select the desired floor, and control other functions of the elevator. The LOP typically consists of floor buttons, door control buttons, and emergency buttons. The LOP may also include a display panel that shows the current floor and direction of travel of the elevator. The LOP is connected to the elevator control system, which controls the operation of the elevator. When a passenger presses a button on the LOP, the control system receives the signal and initiates the appropriate action. For example, if a passenger presses the floor button on the LOP, the control system will signal the elevator car to travel to the selected floor. 

We can see that, elevator LOP is essential components of elevator systems that allow passengers to control the movement and operation of elevators. The LOP is located outside the elevator car on each floor of the building. And also the LOP is connected to the elevator control system, which controls the operation of the elevator. If the elevator LOP suddenly stops working, it can cause a lot of trouble for the building's residents and visitors. The inability to use the elevator LOP can be caused by a variety of factors. Here are some possible reasons why the elevator LOP isn't working and how to fix it:

● Power failure

If the elevator call board suddenly stops working, it may be due to a power failure. You can check the elevator's control panel to see if there is a problem with the power supply. If you find that there is a problem with the power supply, you need to replace it in time.

● Connection failure

The elevator call board may also have a connection failure. If this is the cause of the problem, you can try to reconnect the elevator call board. First, you should check whether the elevator call board is properly connected to the control panel. If the connection is correct, but the elevator call board still does not work properly, then you may need to replace the connection wire.

In LOP, display board plays an important role in operating the elevator. Each elevator has a call board on each service floor. The call board is the main means of interaction between the elevator and passengers. The information conveyed by the call board includes the direction of the elevator and the floor the elevator is currently on. Passengers use the call board to give the elevator boarding instructions. When the elevator call button is used, press the up button to go upstairs and press the down button to go downstairs.
