And in May 2015, a KQ2 series One-touch fitting with an oval release button was added.

Note 1) Meter-in control is easily affected by load fluctuations which may make control difficult. Refer to the FAQ section for further details on the differences between meter-in and meter-out control.

However, a pressure error may be generated each time purge pressure is applied.
Also, depending on the set value, unwanted output may occur, so use a set value that will not produce any undesired effects.

If the error does not disappear after returning to the flow rate range, foreign matter or moisture may have adhered to the sensor or the sensor or circuit board may be damaged. Perform inspection as needed.

When the product is used with an inlet pressure exceeding 0.2 MPa, it may be difficult to set the operating flow rate to a low flow rate as there may be interference between the lower limit slit on the scale plate and the indicator needle, making it impossible to set the value.
If this happens, remove the cover of the flow switch, and follow the setting procedure.

In some cases, if the circulating fluid flow rate is insufficient, it may prevent the temperature from stabilizing.
Another possible cause is an excessive amount of piping resistance that makes it is difficult to secure the flow rate. Also, if there was no problem before, check if the flow rate has decreased due to clogging of the filter, etc.

A large differential pressure may have been generated momentarily during cylinder operation.
Factors that cause a large differential pressure include changes in speed and an increase in hydraulic oil viscosity due to changes in temperature (in winter), which may also cause aging of the pump. Check the situation and contact SMC if you require further assistance.

When temperatures are low, such as in winter, the viscosity of the hydraulic oil used may increase, and the differential pressure indication switch may mistakenly be activated.
In such cases, wait until the fluid temperature rises after it is warmed up, and reset the differential pressure indication switch before starting the main operation (20°C or higher is recommended).

This may be due to some accident such as excessive external force, contamination, or electrical malfunction.  If this happens, it is possible to replace an individual return unit for one lline without having to replace the entire manifold.  The return unit may consist of a flow sensor block with or without a flow adjustment or stop valve, a temperature sensor, or a combination. 

This may be due to some accident such as excessive external force, contamination, or electrical malfunction.  If this happens, it is possible to replace an individual supply unit for one lline without having to replace the entire manifold.  The supply unit may consist of a basic block, a flow adjustment or stop valve, or a combination.

Series PSE digital pressure switches allow pressure to be controlled from a remote location.  Series PSE510 is compact and lightweight, allowing the sensor to be mounted where needed. The use of stainless steel for all wetted parts (SUS630 for diaphragm, SUS304 for fitting) allows the PSE520 pressure sensor to be used in a wide variety of gas and fluid applications.
