Installation
】
Please read the catalog carefully before installation. Failure to follow the instructions in the catalog may cause danger or cause unpredictable results such as
product damage.
Do not connect the panel to the power supply during installation, because of the danger of electric shock or equipment damage, which may cause personal injury
or damage the electrical circuit.
Please install the control panel on the wall about 1.2 meters above the ground and in a location with good ventilation and circulation. Do not install it in a location
that is directly exposed to heat, damp, dusty or vibrating, so as not to affect the control effect or product life.
The transmission distance between the main communication network FCnet and the sub-communication network SCnet is less than 300 meters. It is
recommended to use AWG22~24#2C paired copper mesh to isolate and shield the cable. For more than 300 meters, it is recommended to use AWG18~20#2C
paired copper mesh
the
er meter.
The RS485 communication network must adopt a daisy chain connection mode of one input and one output, and it cannot be divergent or star-shaped, and keep
the positive and negative polarity of the potential consistent.
The front and back ends of the RS485 communication network should be equipped with 120Ω terminal resistors to effectively improve the stability of
communication quality. The total length of the network should not exceed 1,200 meters.
When the group control panel is within 20 meters from the DF.. controller, you can use AWG22~24#4C twisted copper mesh isolation shielded cable to connect
(two of the cores are used for connecting to the power supply), and the DF.. controller can be used nearby. 5VDC power supply (terminals V+&V-) on the power
supply; if the distance exceeds 20 meters, a 5VDC power supply must be configured independently. Remember! Do not share the power supply with other
equipment, so as to avoid the short circuit burnout caused by the difference in circuit design.
FCnet and SCnet communication networks should be covered with EMT metal conduits, and should not be co-managed with power lines or power lines to avoid
noise interference.
To download the graphic control screen, set the parameters or update the firmware version of the panel, you need to use the computer to run the NFTeditor
software to operate
.
Notice! Please unplug the external 5VDC power supply before connecting to the computer
, and then connect it to the computer with a
Mini USB transmission cable, and use the computer's USB port to directly supply 5VDC, so that the computer and panel information can be transmitted smoothly.
