Important Installation Consideration
A 1000 kg gate should not simply be matched with a 1000 kg-rated motor and installed.
Before installing an automatic sliding gate motor, the gate should move smoothly and freely.
The following should be checked:
- Gate wheels
- Track alignment
- Bearings
- Gate structure
- Rack alignment
- Mechanical stops
- Rolling resistance
A powerful motor cannot compensate for a poorly aligned or mechanically damaged sliding gate.
3. 24V Motor System
The BH30/804 uses a 24V motor power supply and a 230V AC, 50/60Hz mains supply.
The system uses brushless motor technology with electronic control through the B70/1DC controller.
The 24V architecture is well suited to modern automatic gate automation systems and allows the motor and control electronics to work together for controlled gate movement.
4. Digital Encoder for Precise Gate Movement
The BH30/804 incorporates a digital encoder.
The encoder specification is:
Digital native encoder + magnetic digital SENSORED, 4096 PPR.
An encoder provides the control system with information about motor movement and position.
This is important because an automatic sliding gate should not simply switch the motor ON and OFF. The controller needs to manage the movement of the gate and respond correctly to its position.
The B70/1DC control system also provides encoder diagnostics and troubleshooting functions.
5. Magnetic Limit Switch
The BH30/804 uses a magnetic limit switch.
A limit switch tells the automation system when the gate has reached its required open or closed position.
The B70/1DC controller supports magnetic and mechanical limit-switch configurations.
Correct positioning of the limit switches is important for reliable gate operation.
After adjusting the limit switches, the gate travel acquisition procedure should be performed according to the manufacturer’s instructions.
6. Intensive-Use Sliding Gate Automation
The BH30/804 is designed for intensive use.

7. 880N Thrust
The BH30/804 provides a specified thrust of 880N.
Thrust is the force generated by the motor to move the sliding gate.
However, thrust should always be considered together with the actual gate installation.
Factors such as gate weight, gate length, wheel condition, track alignment, wind exposure and mechanical resistance can affect the required motor capacity.
For this reason, professional assessment of the gate is recommended before selecting the motor.
8. 12 m/min Operating Speed
The specified manoeuvre speed of the BH30/804 is:
12 m/min (0.20 m/s).
The actual opening time depends on the travel distance of the gate.
For example, a gate with approximately 6 metres of travel would theoretically take around 30 seconds at a constant 12 m/min speed.
Actual operating time can vary because the automation system manages acceleration, deceleration, limits and other operating parameters.
9. Built-In B70/1DC Digital Controller
A major feature of the BH30/804 is its integrated B70/1DC digital control unit.
The controller manages the operation of the automatic sliding gate and provides several important functions.
