When "8" is shown on the display. It is called 7-segment because 8 consists of 7
pieces of "- (segments)".
A function of the Pressure switch to automatically setup pressure just by having
equipment hold and release a workpiece via vacuum adsorption. This function is
used in an application where vacuum adsorption of a workpiece needs to be
confirmed with a Pressure switch.
A function to correct the set value of the switch output in accordance with the
applied pressure in case the switch operation is unstable due to pulsation of
applied pressure. This function is used in applications such as vacuum
adsorption. The pressure when a signal is externally input is set as a reference
value with which the pressure that turns the switch on or off can be shifted.
This function is enabled only when all connected sensors are PSE530 series.
(If just one is a different sensor, malfunction can result.)
The pressure range of the connected sensor is automatically identified and set.
Shows the minimum pressure reached at that moment.
The function to display the displayed values from CH1 to CH4 in order every two
seconds.
The phenomenon caused in the switch output type in which the output turns on
and off repeatedly at high frequency.
A function to delay the response time of switch output in order to prevent
chattering.
The function to copy the settings of any channel (pressure and other initial setting
items) to other channels.
If the copy is performed from a one output channel (= CH2, CH3 and CH4) to a two
output channel (= CH1), it will not be applied to the setting of the second output of
the two output channel.
Shows how precisely the pressure can be indicated or set by the digital Pressure
switch. When 1 digit = 1 kPa, the pressure is given with an increment of 1 kPa,
e.g., 1, 2, 3, ..., 99, 100.
One of the switch output types, and means the operation in which a switch is
turned on when pressure equal to the switch output set value or less is detected.
In the (hysteresis mode) window comparator mode, it indicates the operation in
which a switch is turned on when pressure outside the switch output range (n1L to
n1H or n2L to n2H) is detected.
(Refer to "List of output mode" on page 20.)
With the self-diagnosis function given to the Pressure switch, it indicates that
there is a failure which could cause a switch failure.
