<br>When the LED is ON (red), this indicates a high-voltage error has occurred.<br>The main cause of this is usually foreign matter or water droplets adhering to the emitter (electrode needle).<br>Remove the cartridge and clean the emitter after stopping the power supply and air supply.
<br>Brackets can only be retrofitted for valves with an “XNB” part number suffix as they feature mounting holes on the bottom surface of the body. <br>Some VXD and VXZ series valves can be retrofitted with brackets depending on the model. <br><br>Note 1) The type with a resin body comes with brackets as standard.
<br>Keep in mind that if you wish to make changes after purchase, disassembly is required, which will void the product warranty. <br>Refer to the “Disassembly/Assembly Procedures” in the “Specific Product Precautions” section at the end of the catalog. (The VXZ series valve is not listed.) <br>The VX series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=fluid-process-valves&fa_id=10545
<br>Due to the pilot type structure, a pressure differential between the inlet and outlet sides is required. <br>Check the catalog to see if the product is suitable for your application. <br>The VQ20/30 series catalog can be found here.
<br>Therefore, these valves cannot be used in circuits that require the pure water to retain its level of purity. <br>For such circuits, consider using a product from the LV series. <br>The LV series catalog can be found here.<br><br>
<br>For piping connection, pipe the vacuum pump to the A port side of the valve. <br>If the B port side is used as a vacuum source, the service life of the product may be shortened. <br>Note) LVA and LVC series valves cannot be used with chemical gases. <br>Also, they cannot be used for vacuum retention. <br>The LVA series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=high-purity&fa_id=11182
<br>When using pure water (deionized water), select option “M” (deionized water piping). <br>This specification does not use copper-based materials for the wetted parts of the circulating fluid circuit. <br>Note 1) For details on water quality standards, refer to the HRS series “Specific Product Precautions.”
<br>Note 1) The discharge pressure can be set for HRSH series thermo-chillers. <br>Note 2) The pressure cannot be displayed for HRSE series thermo-chillers.
<br>Check that there is no restriction in the piping, including the customer’s device. <br>If there is restriction, thicken the piping or relieve the circulating fluid flow rate with a bypass piping set. <br>Depending on the problem, however, consider requesting maintenance from a maintenance company. <br>We can recommend service providers if needed.
<br>Alarm code “AL28” (pump maintenance) will be activated every 20,000 hours (every 8000 hours for option “T” and the HRS050/060) of operation. <br>Consider requesting maintenance from a maintenance company. <br>We can recommend service providers if needed.
<br>Even if there is no leakage, replacement of the mechanical seal is recommended. <br>The mechanical seal can be replaced up to 2 times. If foreign matter enters the circulating fluid, leakage may occur earlier. <br>For protection of the mechanical seal pump, we recommend the installation of a particle filter.
<br>When replacing, follow the replacement procedure in the operation manual and the element replacement procedure (published on the SMC website). <br>The FGD series catalog can be found here. <br>The FQ1 series catalog can be found https://www.smcpneumatics.com/Part-Builder-Links_ep_2458-1.html?https://smccatalog.partbuilder.smcpneumatics.com/support/faq/en-jp/?ca_id=industrial-filters&fa_id=10645
