●The switch must be balanced and pressed on the fixed bracket of the rack;

●Tie the steel wire rope to the pull rings at both ends, and the rope on each side should not exceed 40m (it should be shortened when there is a slope);

●The pressure on the pull rope should be appropriate to ensure reliable reset of the switch;

●The drawstring is set parallel to the tape, and a lifting ring is added every 10m.

●The factory can purchase steel wire ropes according to the specifications required by users.

The address encoder uses a self-designed protocol to provide an RS485 communication interface to connect to the comprehensive protection instrument. By using shielded twisted pairs and communication repeaters, the transmission distance can reach 1km.
