Multi-channel Controller/Pressure Sensor
Function Details

PSE530/200
A Display calibration function
This function eliminates slight differences in the output values of all 4
channels and allows uniformity in the numbers displayed. Displayed
values of the pressure sensors can be adjusted to within ± 5%.

If there is a fluctuation in the supply pressure, erroneous operation may
occur (e.g., in the case of adsorption verification, the switch does not turn
ON even though the workpiece is being adsorbed, or does not turn OFF
even though the workpiece is no longer being adsorbed.)
The auto shift function rectifies pressure changes to ensure proper
ON/OFF switch response during such fluctuations.

<Principle>
At the point when the supply pressure fluctuates, the set pressure value is
rectified by setting the auto shift input (external input) to Lo (no-voltage
input), using the pressure measured at that point as a standard.
? This function is good only for those channels whose function selection is
turned “on” during the auto shift mode setting.
? Maintain the constant pressure for 10 ms or more after a drop in the auto

? The time from the moment the auto shift is input, to the moment the
switch output actually operates is 15 ms or less.
? If the set value rectified by the auto shift input exceeds the regulating
pressure range, it will be rectified once more to within the values of the
regulating pressure range.

D Auto identification function
E Unit display switching function
Display units can be switched with this function.
Units that can be displayed vary depending on the range of the pressure
sensors connected to the controller.
This function automatically identifies the pressure range of the pressure
sensor that is connected to the multi-channel pressure sensor controller,
thus eliminating the need of having to reset the range again after

that condition. However, this function only works in conjunction with
specific pressure sensors (SMC Series PSE53 ). When other pressure

pressure sensors, first set the auto identification mode to “AoF”, and then
proceed to setting the range. Turning the power back on while in the “Aon”
setting can cause a malfunction.
