This glossary explains clearly and directly the terms you'll see when choosing or repairing elevator electronic boards. Each entry includes the practical meaning and an example from the Alamex board where it appears, so you can identify the correct spare part and request a quote with more confidence.
›››Communication and Protocols
CAN-BUS: Serial network communication protocol that allows the main board and car to exchange control information. Example: Serial and Main Board ML65X — "CAN-BUS with the car".
Gray Code Outputs: Analog or encoded signals that transmit positions or states with proportional levels, useful for displays or equipment that interpret values. Example: Serial Board ML65XL — "Internal gray code outputs".
Binary Outputs: Signals that take only two states (on/off), used to activate relays or indicators. Example: Board for Italian control — "Display outputs: Changeable to gray code or binary outputs".
›››Control and Operation Functions
Main Board: Unit that coordinates system inputs and outputs, manages floors and service logic. Example: Main ML65XL — "Floors: 24 floors".
Serial Board: Module that extends communication and special functions, such as battery charging or high-speed outputs. Example: Serial Alam 03 — "Output: Special output for high speed".
Releveling: Function that adjusts the car position to level with the floor, even with doors open or closed. Example: Main Alam 03 — "Releveling: With doors open or closed".
›››Interfaces and User
LCD Display and Buttons: Local interface to configure parameters and view status or maintenance notices. Example: Board for Italian control — "Configuration: Parameters through the LCD display and buttons".
Password Protection: Mechanism that prevents unauthorized changes to configuration from the local interface. Example: Board for Italian control — "Password protection against unauthorized use".
Spanish Voice Announcer: System that alerts users in voice about stops or directions in Spanish language. Example: Main Alam 03 and Serial Alam 03 — "Voice announcer: Spanish language".
›››Power Supply and Electrical Protection
Power Supply 20VAC±10%: Voltage value required by the car operator board for its control circuit. Example: Car Operator Board ALAM — "Power supply: 20VAC±10%".
Short Circuit Protection (8A): Safeguard that prevents damage from overcurrent in the power supply; acts when current exceeds 8 A. Example: Car Operator Board ALAM — "Power protection: Short circuit (8A)".
Power Consumption 10W (control circuit) + motor: Indicates control circuit consumption; the motor is considered separately. Example: Car Operator Board ALAM — "Maximum power consumption: 10W (control circuit) + motor".
›››Inputs, Sensors and Compatibilities
Compatibility with Variable Frequency Drives: Indicates that the board can work with different models of motor speed variable frequency drives, which facilitates integrations. Example: Main Alam 03 — "Compatibility: Different variable frequency drive models, including Yaskawa".
Sensors and Encoder: Position detection options; in some cases, if an encoder is used, other level sensors are not necessary. Example: Serial Alam 03 — "Sensors: 5 sensor options (in case of encoder, level sensors are not necessary)".
Special Output for High Speed: Dedicated signal for equipment that requires a different pulse or signal when operating at high-speed range. Example: Serial Alam 03 — "Output: Special output for high speed".
- Among the spare parts we're most asked for are the Car Operator Board ALAM and the Main Board ML65x.
›››Frequently asked questions
What is the difference between main board and serial board?
The main board handles central logic and outputs; the serial board complements communication and adds specific functions such as battery charging or high-speed outputs.
Can I switch outputs between gray code and binary?
Yes: some boards allow you to select between gray code outputs or binary outputs depending on the connected equipment, such as the Board for Italian control with changeable display outputs.
What does it mean that a board is compatible with Yaskawa?
It means that the board is designed to communicate and function with variable frequency drives from the stated manufacturer, as indicated by the compatibility of the Main Alam 03.
