5.4 Installing Limit Switches:
Position the magnetic limit blocks at the desired open and closed positions of the gate. These magnets signal the motor to stop.
Figure 5.4: Magnetic limit switches ensure precise stopping of the gate at its fully open and closed positions.
5.5 Electrical Connection:
Connect the gate opener to a dedicated 110V/60Hz AC power supply. Ensure all wiring is secure and protected from environmental elements. Consult a qualified electrician if you are unsure about electrical connections.
6. Operating Instructions
Your Blütezeit MJ-400 gate opener offers multiple modes of operation for convenience and security.
6.1 Remote Control:
The included rolling code remotes provide secure access. Each remote has four buttons (A, B, C, D) for various functions.
Figure 6.1: The 4-button remote control for operating the gate opener from a distance.
- Open/Close: Typically, one button is programmed to open and close the gate fully.
- Pedestrian Mode: The 4th button (often labeled D) activates Pedestrian Mode, opening the gate partially (adjustable 5-30 seconds) for foot traffic.
- Stop: Another button may be programmed to stop the gate's movement at any point.

6.2 Condo Mode:
In Condo Mode, a single remote press opens the gate fully until the open limit switch is triggered. A second press will close it. Interrupting the gate's movement with a photocell or remote command will immediately re-open the gate, temporarily disabling Pedestrian Mode for safety.
