Limit switch adjustment
Use the manual release key to unlock the gate opener and manually move the gate to the predetermined position. Fix the magnetic limit
switch block and close the clutch. Test its operation and adjust the position of the magnetic limit switch block incrementally until the gate
reaches the desired open and close limit locations.
Installation of magnetic limit switch block is shown in Figure 13 and 14 (97 mm = 3.82 in., 35 mm = 1.38 in., 20 mm = 0.79 in.):
Warning
To ensure safety, install safety stop blocks on both ends of the rails to prevent the gate from getting out of the rail. Before install-
ing the main engine, make sure that the safety stop blocks are in place and capable of preventing the gate from moving out of
the rail or the safety range.
Please ensure that the main engine and its components have good mechanical properties, and the gate can operate flexibly
when moved by hands before installing the main engine.
Only use one control to drive one control board at one time. Otherwise, the control system and device may be damaged.
An earth leakage circuit breaker must be installed where the gate movement can be seen, and the minimum mounting height
should be 4.92 ft. to protect it from being touched.
After installation, please verify that all mechanisms are operating correctly and whether the gate still moves flexibly under
manual control after being unlocked.
