SMC Electrical Proportional Valve User Manual

SMC Electrical Proportional Valve User Manual

About piping
1. Please blow or clean the piping with air to remove chips, cutting oil, and impurities inside the piping.
When tightening the piping and pipe joints, please be careful not to mix the thread chips and sealing materials of the piping into the piping.
It should also be emphasized that when using sealing tape to wrap the threads of pipe joints, please leave a space of 1.5-2 pitches at the tip of the thread.

About compressed air source
1. On the gas supply side near this product, please choose to install an air filter with a filtration accuracy of less than 5 μ m.
If compressed air contains a large amount of moisture, it will cause poor operation of this product and other pneumatic components. Please implement corresponding measures,
Such as setting up aftercoolers, air dryers, moisture separators, etc.
When a large amount of carbon powder generated by the air compressor adheres inside this product, it will cause poor operation.

Wiring Methods
When connecting the cable to the terminal of the body, please wire it in the following form.
Due to the possibility of damage caused by misconnection, please be careful when using.
Please use a DC power supply with sufficient capacity and low pulsation.

Note that cables also have a right angled cable shape. Right curved linear cable terminal
Line out to the left (SUP port side). The terminal cannot rotate, please
Do not rotate the terminal arbitrarily.

Key locking function
After connecting to the power supply, if this product is in the key lock state, the key operation is invalid.
At this point, if you press the button, the LED will display as "".

Release method of key lock
Press the ▽ key continuously for more than 2 seconds to display the LED
The words' middle 'flash alternately. Press now
The SET key is used to unlock the key.
(If you press the △ key, the above operation will be canceled)

Operation method of key locking
Press the △ key continuously for more than 2 seconds to display the LED
The words' middle 'flash alternately. Press now
The SET key sets the key lock state.
If you press the ▽ key, the above operation will be canceled

Adjustment of minimum/maximum pressure
This product can adjust the minimum and maximum pressure for input signals, with a minimum pressure of 0-50% (F.S.) and a maximum pressure of 100-50%
Adjust within a range of 10% (F.S.).

display output
The output voltage for display is shown in the table below. Please ensure that the load impedance used for the measuring devices connected to this product is above 1k Ω. another
Furthermore, when increasing the output voltage, please also consider designing the load impedance to be above 1k Ω.

Note that the "output voltage" referred to here is due to the characteristics of the built-in pressure sensor and the measuring devices connected to it, as well as the load resistance of the electrical circuit
Please be aware of the slight changes in resistance.

SMC Electrical Proportional Valve User ManualPrecautions for use
attention
1. This product can maintain the outlet pressure on the secondary side for a short period of time when the power supply is cut off due to abnormal situations such as power outages during control.
When the secondary side is in an open state to the atmosphere, the air will continue to be discharged after a power outage. Please pay full attention when using it.
When this product stops supplying pressure while powered on, the built-in solenoid valve may continue to operate, which may cause noise. When the gas supply is stopped, please
Be sure to cut off the power supply at the same time.
When the display output is not in use, it may cause misoperation. Please be careful not to contact the display output terminal with other wires.
4. The specifications and parameters of this product have been adjusted before leaving the factory. Customers are advised to avoid aimless disassembly and assembly of parts
Prevent malfunctions.
To avoid misoperation caused by interference signals, please implement the following measures.
1) Please add an online filter to the AC power cord to remove power noise.
2) Please try to isolate strong electrical facilities such as electric motors and power lines from this product and the wiring associated with it, so that this product is not affected
The impact of interference signals.
3) Please implement load buffering measures for induced loads such as solenoid valves, relays, etc.
6. Due to the inability to rotate the right angled cable terminal, please do not rotate the terminal arbitrarily.
