Single Column Controller Instruction Manual

I. Function Introduction

The intelligent single column controller offers the following features:

• Controls two motors for synchronous operation.
• Displays the operating height in real-time.
• Supports four-position settings with power-loss memory.
• Includes an anti-rebound feature when encountering resistance (optional).
• Supports wireless remote control (optional).

II. System Parameters

• Input Voltage: DC29V
• Input Current: Recommended above 1.8A, depending on the load.
• Maximum Output Voltage (Motor Interface): DC29V
• Maximum Output Current (Motor Interface): 4A
• Operating Temperature: 0~40℃
• Working Humidity: 20~90%
• Storage Temperature: -20~70℃

III. System Connection

The system comprises:

• a. Handheld controller
• b. Main controller
• c. Telecontroller
• d. Non-part of the system (user-provided components)

IV. Motor Interface Plug Definition

Defines the connections for the motor interface:

• Motor Power: (+/-) 0~29VDC
• Motor Power: (+/-) 0~29VDC
• Hall Switch: 2ch
• Hall Switch: GND
• Hall Switch: 1ch
• Hall Switch: Vcc (5VDC)

V. Fault Code and Treatment

1. Fault Code Err1

If the manual controller displays "Err1", it indicates a fault with the M1 interface channel. Potential causes include incorrect motor connection, improper Hall signal board connection, or a broken connection wire.

Troubleshooting: After resolving the issue, press and hold the "down button" for over 3 seconds to clear the fault display and reset the system.

VI. System Reset

1. Prompt Reset

When the manual controller displays "RST", a manual reset of the entire system is required.

2. Line Reset

If the manual controller shows the minimum height (e.g., a reset height of 60cm), press and hold the "down button" for more than 5 seconds.

3. Reset Method

When the manual controller displays "RST", press and hold the "down button". The column will begin to shorten slowly. Observe for any damage during operation; if any occurs, release the "down button" immediately. The column will shorten during resetting.

After the column reaches the lowest point, it will pause briefly and then rise 5-10mm. Once the "RST" display disappears, the reset is complete, and the hand can be released.

VII. Preset Target Height

1. Number of Preset Target Heights

The system provides 4 sets of target height presets, with data saved for over 10 years.

2. Initial Preset Target Height

Initially, all 4 sets of target height data are set to the minimum height before any manual adjustments.

3. Deleting Target Height Data

The system does not have a separate erase function. Setting a new target height parameter automatically overwrites the old one.

4. Method of Presetting Target Height

At any height (except in reset or error states), the current height can be saved to keys 1-4. For example, to save the current height of 97 to key 2: Press the "S" key to display "SET", then within 2 seconds before "SET" disappears, press "2". A display of "S-2" indicates the setting is complete.

5. Using Preset Target Heights

At any height (excluding reset or error states), the preset target heights can be quickly accessed using keys 1-4. If the current height is already near the target height, no action will be taken.

VIII. Way to Change Height

1. Column Elongation

a. Handheld Controller Operation: Use the "up button" for elongation. The column stops automatically at the travel limit. Releasing the button initiates a stop command, but the column will decelerate over a short distance before stopping completely.

b. Telecontroller Operation: Use the "up button" for elongation. The column stops automatically at the travel limit. Releasing the button does not immediately stop the operation; pressing any key again will issue a stop command. After the command, the column will decelerate over a short distance before stopping.

2. Column Shortening

a. Handheld Controller Operation: Use the "down button" for shortening. The column stops automatically at the travel limit. Releasing the button initiates a stop command, but the column will decelerate over a short distance before stopping completely.

b. Telecontroller Operation: Use the "down button" for shortening. The column stops automatically at the travel limit. Releasing the button does not immediately stop the operation; pressing any key again will issue a stop command. After the command, the column will decelerate over a short distance before stopping.

IX. Telecontroller Pairing Operation

1. Matching Window Period

A 3-second window period for pairing occurs after repowering. A single beep indicates the end of this period.

2. Pairing Method

During the pairing window, press and hold the "up button" on the remote. Wait for 4 long buzzing intervals and 3 short buzzing intervals, indicating successful pairing. Release the "up button" after the correct buzzing sequence. The system will then recognize the remote's code.

X. Slow Rise and Fall

In all modes, motors start and stop using a gradual speed change, known as "slow rise and fall," to minimize impact on the desktop during operation.

XI. Backtracking When Encountering Obstacles

Outside of the reset state, if the mechanical structure encounters a sudden change in load during operation, the controller will initiate a fallback operation to prevent injury from external forces.

Important Note: During resetting, please pay special attention to whether there are people or objects under the table that may cause harm.
