<br>If the desired performance can longer be obtained, replace the product immediately, regardless of the number of years of operation.

<br>Install a water separator for water droplet removal and a mist separator (AM or AFM series) and a micro mist separator (AMD or AFD series) for oil mist removal.

<br>Note) The nominal filtration ratings of the elements of each device installed allow for the compressed air required for the application to be created in stages. For example, if an AFF⇒AM⇒AMD combination is changed to an AFF⇒AMD combination, the AMD element will get clogged much more quickly.

<br>For filters with a drain cock, loosen the discharge port knob on the bottom of the case to discharge the drain. After discharge, return the knob to its original position. Manual operation is also possible for the auto drain type. Loosen the knob on the drain port until it points to “O” (OPEN) to discharge the drain. After discharge, return the knob to “S” (SHUT) by retightening it.

<br>(e.g., IR3020 sensitivity: 1.6 kPa←800 kPa x 0.2% [800 kPa = 0.8 MPa])

<br>The abnormal sounds are most likely the operating sounds of the solenoid valves. A sound can be heard during the pressure setting operation, but the sound stops when outlet air consumption stops and the set pressure is reached.

<br>Note) The power cable part number is the same for DeviceNet, CC-Link, PROFIBUS DP, and RS-232C, but since it has 4 cores, use only the brown and blue wires.

<br>You can also suffix “-X400” to the ITV series regulator part number to add a gauge port via special order.

<br>The SRH series catalog can be found here.

<br>Note) Even if the regulator has a relief mechanism, there is a slight difference between the relief start pressure and the set pressure, so the pressure may increase by that difference.

<br>Therefore, pressure control is not possible with only a 4 to 20 mA input signal. Note) Old IT1000/2000/4000 series regulators of the 4 to 20 mA input signal current type were a 2-wire type, but they were designed to not require a power supply voltage.

<br>The ITV1000/2000/3000 series troubleshooting guide can be found here.

<br>Information on the AR-X2400 can be found here. And the SRH series catalog can be found here.

<br>Mount an AKM series check valve in front of the lubricator, not a T-type spacer. AKM series check valves are equipped with a branch port to remove non-lubricated air.

<br>When ordering separately to retrofit to an AC□-□-A without a pressure switch, order the IS10M-□-L-A pressure switch with a lead wire length of 3 m and a spacer for assembly.

<br>Note) Continuous energization is when power is applied for 30 minutes or more or when the energized time per day is longer than the de-energized time.

<br>In addition, the safety categories of VP544/744-X555 dual residual pressure release valves with a soft start-up function are “3” and “4.” Further details on the VP544/744-X555 can be found here.

<br>In addition, even for low power consumption types, it is recommended that the valve be switched ON/OFF at least once every 30 days to prevent malfunction due to sticking of the valve.
