The electric controllers U, V and W of the 7-wire roller shutter motor are motor wires, which provide voltage for the motor.
2.w is the temperature sensing access line, Y is the smoke sensing access line, and the smoke sensing and temperature sensing terminal needs to be connected to the public terminal before it can be used.
3.XJ is the down terminal, SJ is the up terminal and TJ is the stop terminal. These terminals are mainly connected to the manual control button box.
4.k is the upper feedback and g is the lower feedback. These two terminals are mainly connected to the fire control module for feeding back the lifting information of the fire shutter door.
Eight-hole six-wire rolling gate controller
1. Three-phase power supply: Three-phase power supply is used to drive the motor to work, so there is nothing to say.
2. 1 ~ 6 terminal is connected to the shutter switch box. It can be connected to the terminal on the switchboard. It is mainly used to control the rising, falling, stopping and resetting of the shutter door. This is also the manual field control part.
3. Half drop/full drop (7~9). This is mainly connected with the fire alarm host, generally connected with the control module on the detection loop of the fire alarm host. Take FDCIO 18 1 as an example. Using the output of the dry contact of the control module (the switch is closed), the full down/half down of the shutter door is directly controlled, and then the feedback of the full down/half down (that is, the middle feedback and the lower feedback) is connected to the input end of the control module, so that the feedback is transmitted to the fire alarm host, so that the staff in the central control room can know that the shutter door is fully down or half down.
