	3	+This manual has a comprehensive introduction to the basic functions of WECON PLC Editor and the actual use. This book is completely aimed at zero-based readers, is an essential reference book for entry-level readers to quickly and fully grasp WECON PLC and WECON PLC Editor.
	4	+
	5	+This book starts from the basic product of WECON PLC and the basic concept and operation of WECON PLC Editor. It combines with a large number of cases and graphic analysis to comprehensively and deeply explain the use of WECON PLC Editor Software, as well as PLC program.

	10	+
	11	+Before the installation, operation, maintenance and repair of the micro programmable control, please read this manual and other related manuals to ensure correct use. Please use it after you have mastered the operation method, safety information and all
	12	+
	13	+== Design ==
	14	+
	15	+In the event of an abnormality in the external power supply or failure of the programmable controller, to ensure the safe operation of the entire system, be sure to install a safety circuit outside the programmable controller.
	16	+
	17	+1. Be sure to install an emergency brake circuit, a protection circuit, an interlock circuit for reverse operation, such as an emergency brake circuit, a protection circuit, a forward and reverse circuit, and an interlock circuit for the upper and lower positioning limits to prevent machine damage, in the external circuit of the programmable controller.
	18	+1. When the programmable controller CPU detects abnormal conditions such as WDT errors through self-diagnosis, all outputs are shut off. In addition, when the programmable controller CPU cannot detect abnormalities in the input/output control part, etc., it cannot control the output. At this time, in order to make the machine operate safely, please design the external circuit and mechanism.
	19	+1. Due to the failure of the relay and transistor of the output unit, it is impossible to control the state of the output to ON or OFF. In order to ensure the safe operation of the machine, please design external circuits and mechanisms for output signals related to major accidents.
	20	+
	21	+== Installation ==
	22	+
	23	+* Please use it in the general specification environment described in the manual.
	24	+** Do not use in the following places: places with dust, oily smoke, conductive dust, corrosive gas, flammable gas; places  exposed to high temperature, condensation, wind and rain; places with vibration or impact. Electric shock, fire, and misoperation can also cause product damage.
	25	+* When processing screw holes and wiring, do not let iron filings or wire ends fall into the ventilation window of the programmable controller. It may cause fire, malfunction, or misoperation.
	26	+* Please insert the connecting cable and display module accurately into the specified sockets. Poor contact may cause misoperation.

	30	+**✎Note:**
	31	+
	32	+* To prevent the temperature from rising, do not install at the bottom, top or vertical direction.Be sure to install it horizontally on the wall as shown on the right.
	33	+* Please leave a space of more than 50mm between the host and other equipment or structures.Try to avoid high-voltage lines, high-voltage equipment, and power equipment.
	34	+)))
	35	+
	36	+== Wiring ==
	37	+
	38	+The signal input and output lines of the programmable controller cannot pass through the same cable.
	39	+
	40	+In addition, signal input lines and output lines cannot pass through the same pipeline with other power lines and output lines, and cannot be bundled together.
	41	+
	42	+If implemented according to the above precautions, even if the input and output wiring is as long as 50 to 100m, there is almost no noise problem. But generally for safety, the wiring length should be within 20m.
