12). Keep 1~2 mm space as Figure 29 between the rack and pinion so that the gate does not weigh on the gearmotor.
Continually install the other pieces of the rack until the racks are sufficient for work.
13). Release the gearmotor by using the release key if necessary.
14). Open and close the gate several times manually and make sure that the rack goes with the pinion smoothly
within a maximum tolerance of 5mm
15). Fix the two limit switch brackets with the relative dowels as the part in Figure 30.
Slide the gate in the open position keeping at least 2~3 cm from the limit switch. And then slide the bracket along
the rack in the opening direction until the limit switch cuts-in. The brackets should be located at a sufficient
distance from mechanical stops in order to keep the gate from crashing.
Operate the same steps for the limit switch installed in the closed position.
16). For electrically connections of the various devices, please see “4.1.1 Design of PL600/PL1000
Control Unit”.
