Wiring Notifications
：
⚫
When using a solenoid valve or other inductive loads, please apply an arc
extinguisher or RC voltage dependent resistor RC to ensure the life of the
contact points. Advantages of the arc extinguisher:
1) Extend the life of electrical contacts.
2) Reduce the sparks from the contact points.
3) Prevent the inductive loads from interferences caused by back EMF.
4) Restrain the impulse voltage.
⚫
If the server line you are using is not a standard Syntec cable, please check all
the terminals and make sure they are connected properly before running a
test. The wrong wiring will lead to the controller output command error and
cause malfunctioning.
⚫
MPG terminal’s +5V output capacity is 200mA and it is only for a single
external hand wheel. Do not connect it with other loads or it might cause
malfunction due to the lack of drive capacity.
⚫
The external 24V power supply used in wiring should be certificated and
protective to avoid the malfunction caused by wiring mistakes.
(Recommendation standard
：
fulfill requirements of both EN60950 and
UL1950)
⚫
Please crimp or weld the wire connections while doing the wirings.
⚫
In case of the use of Ethernet, to prevent the internet congestion and noise, the
CAT5e or CAT6 cable are recommended.
⚫
Do not use counterfeit terminal strips. Those terminal strips cannot provide
overall protection for the system. The quality is also not guaranteed and
prone to cause electrical control problems of the machine tools.
⚫
Grounding Directions:
1) The length of the grounding wire should follow the electrical equipment
regulations. The shorter the better.
2) The grounding wire of the controller should be separated from those with
large current loading such as electric welders or high frequency motors.
3) Please refer to the pictures below when the controller is grounded with
multiple electrical control devices. Do not make it a loop.
