4. Working principle
This product adopts a moving cam structure. When the rope on either side is pulled, the cam is driven. , causing the switch action to change to send out a shutdown signal, the model adopts automatic reset, and the model adopts manual reset.
5. Installation and wiring
Installation
According to the diagram, make a self-made mounting plate, use special bolts to fix the switch on the mounting plate,
Then attach the mounting plate with the switch The device is fixed on both sides of the belt conveyor, and its position meets the following requirements
Generally, the switch is installed on the conveyor frame so that the device is lower than the level of the belt for easy operation
Put the pull rope ( ￠Plastic-coated steel wire ropes) are tied to the pull ring holes of the switch arm respectively. The distance between the two switches should be less than 1. The pull ropes at both ends should be arranged parallel to the belt conveyor, and lifting rings should be installed at the left and right sides of the interval for support to reduce the risk of its deflection.
, Wiring
Wiring Instructions for Type Pull Rope Switch
Open the back cover and you will see the switch wiring bolt. If there is an outgoing cable, the user does not need to open the back cover and can directly connect it to the outgoing cable of the switch. When wiring, use a multimeter to check the normally open and normally closed contacts to prevent errors. After the connection is completed, use waterproof tape to insulate and seal Put on the insulating sheath.
The wiring of the type pull rope switch is the same as that of the type.
Precautions
The wiring connection is reliable and the insulation is sealed.
After the rope switch is installed, the ropes on both sides should be tight and the deflection should be small. After the rope is pulled, the switch can be reliably reset.
