Elevator COP & LOP Panels in Bangladesh
Need a replacement car operating panel or landing call panel? Send photos of the existing panel, controller information, dimensions and connection details so the required COP or LOP can be reviewed before quotation.
COP
Car-side passenger operating interface
LOP
Landing-side elevator call interface
Quick distinction
What is an elevator LOP?
LOP means Landing Operating Panel. It is located at the floor landing and provides the call controls used before a passenger enters the elevator. It may also incorporate floor or direction indication.
Inside the lift car
The COP is more than a stainless-steel faceplate
The visible buttons are only part of the operating-panel assembly.
Behind the faceplate, the panel may contain button contacts, indication electronics, wiring, connectors, circuit boards and interface components. The exact arrangement depends on the installed elevator and controller system.
01
Floor selection
Passenger buttons send the requested floor command through the lift's control interface.
02
Door functions
Door-open and door-close controls may be incorporated according to the existing elevator configuration.
03
Alarm / communication functions
Relevant emergency or communication controls may form part of the car operating panel, depending on the system.
04
Position information
The COP may incorporate a floor or direction display rather than using a completely separate indicator.
COP vs LOP
Two operating panels, two different locations
Identifying the panel correctly matters when requesting a complete assembly, faceplate, display, button board or other replacement part.
Car Operating Panel
Installed inside the elevator cabin where passengers select their destination and use the available car functions.
- Multiple floor-selection buttons
- Door control buttons where provided
- Alarm or communication functions where applicable
- Floor / direction indication where incorporated
- Faceplate, button boards and internal wiring
Landing Operating Panel
Installed outside the lift at a landing so passengers can place an elevator call before entering the car.
- Landing call button or buttons
- Up/down arrangement where applicable
- Floor or direction display where provided
- Surface or recessed mounting depending on design
- Faceplate, button electronics and wiring interface
System context
COP and LOP must communicate with the existing lift control system
A panel that physically fits the opening is not automatically an electrical or communication match.
Before replacing an operating panel, the existing controller, interface method, wiring, connectors, button arrangement and indication requirements should be identified. This is particularly important when a replacement is part of a modernization rather than a like-for-like repair.
Passenger input
A floor-selection or landing-call button is pressed.
Panel interface
The operating panel passes the relevant signal through its installed electrical/interface arrangement.
Lift controller
The elevator control system processes the request according to the system design and operating state.
Feedback
Button illumination, floor information or direction indication may then be updated through the appropriate interface.
Replacement checklist
Details that matter when matching a COP or LOP
Clear information at the enquiry stage reduces guesswork and helps separate a complete-panel requirement from a smaller component replacement.
Panel location
Confirm whether the required unit is the cabin COP or a landing LOP.
Controller information
Send the controller model or identification where it can be read safely.
Existing panel dimensions
Overall faceplate and mounting dimensions may affect replacement selection.
Button arrangement
Record floor count, function buttons and landing call configuration.
Display requirement
Note whether the existing panel includes floor or direction indication.
Wiring & connectors
Clear rear-panel photographs can help identify the electrical interface.
Repair or replacement?
A failed button does not always require a complete new COP
Start with the actual symptom and inspect the affected panel before deciding the replacement scope.
Depending on the fault and system design, the problem may be limited to a button, contact, display, board, connector, wiring or another internal component. Physical panel damage or a broader modernization requirement may justify replacing more of the assembly.
- Check the symptom: one button, several buttons, display, lighting or complete panel.
- Check the location: one landing, several landings or the car operating panel.
- Record displayed faults: photograph useful error information where available.
- Inspect connections: loose or damaged connections can resemble component failure.
- Match before replacement: confirm electrical and physical compatibility rather than relying only on the faceplate design.
Fault identification
Common COP and LOP symptoms worth documenting
These symptoms help narrow the inspection. They do not by themselves prove which component has failed.
One floor button does not respond
The individual button, contact, connection, board input or related wiring may require inspection.
Several COP buttons stop working
Check common connections, panel electronics, power/interface conditions and controller communication as applicable.
One landing call panel is faulty
A floor-specific LOP, button, connection or landing interface may need attention.
Display is blank or incorrect
The indicator, its supply, wiring, interface board or incoming information may need diagnosis.
Button lights but call is not registered
Illumination alone does not confirm that the command is reaching and being processed by the control system.
Panel is physically damaged
Record the faceplate dimensions, mounting arrangement and internal components before planning a complete-panel replacement.
Replacement / modernization
COP and LOP enquiries can involve a complete panel or individual parts
The exact replacement scope depends on what is installed and what has failed. Availability and compatibility should be confirmed before quotation.
- Car operating panel assembly
- Landing operating panel assembly
- COP faceplate
- LOP faceplate
- Floor-selection buttons
- Landing call buttons
- Door function buttons
- Alarm / function buttons
- Floor indicators
- Direction indicators
- Button boards
- Display boards
- Panel wiring
- Connectors and mounting parts
Before requesting price
Send enough information to identify the panel first
A useful quotation depends on knowing what must fit the existing elevator rather than quoting from the words “COP” or “LOP” alone.
01. Front photo
Send a straight, clear photograph showing the full existing panel.
02. Rear / internal view
Where safely accessible by a technician, show boards, connectors
and wiring.
03. Dimensions
Provide faceplate and relevant mounting or cut-out measurements.
04. Controller details
Include readable controller or interface information where known.
05. Required quantity
State whether you need one COP, one LOP, several landing panels or
individual components.
06. Fault / project purpose
Explain whether this is repair, damage replacement or a planned
modernization.

Buyer questions
Elevator COP & LOP FAQ
Straight answers for repair, replacement and modernization enquiries in Bangladesh.
What is the difference between elevator COP and LOP?
COP means Car Operating Panel and is located inside the elevator car. LOP means Landing Operating Panel and is located outside the lift at a floor landing. The COP normally provides destination and car-function controls, while the LOP provides the landing call interface.
Can I replace only one damaged COP button?
Sometimes a fault may be limited to an individual button or related component, but this should be confirmed by inspection. The button type, contact arrangement, board and existing panel compatibility need to be checked before replacement.
Can I use any COP with my elevator controller?
No universal compatibility should be assumed. The controller, interface method, wiring, connectors, panel electronics and physical dimensions should be checked against the proposed panel.
What information is needed for an elevator COP quotation in Bangladesh?
Send clear front and rear photos, panel dimensions, controller information, required button arrangement, display requirement and the quantity needed. Also state whether the project is a repair, replacement or modernization.
Does every landing need the same LOP?
Do not assume that every floor uses an identical arrangement. Terminal floors, intermediate floors and the installed control strategy can affect the landing-call configuration. Check the existing panels before ordering.
Can the COP or LOP be changed during elevator modernization?
Operating panels can form part of a modernization scope, but the new panel must be planned around the controller/interface, required functions, mounting arrangement and the existing or new lift system.
Should I order a complete panel if the display is faulty?
Not automatically. First identify whether the problem is the display module itself, its power or wiring, an interface board or the information coming from the controller. The appropriate replacement scope depends on the diagnosis and parts compatibility.
Need a COP, LOP or operating-panel replacement?
Send the existing panel photos, dimensions, controller details and required quantity. The panel or component requirement can then be reviewed before repair, replacement or modernization options are discussed.
