■ Definition and terminology
Terms Meaning
2
2-color indication
There are two colors to indicate a value, changing in accordance with ON and
OFF of the switch output.
7
7-segment indication
When "8" is shown on the display. It is called 7-segment because 8 consists of
7 pieces of "- (segments)".
(Analog) current output See "Analog output (function)".
Analog output (function) Function to output the voltage or current in proportion to the pressure.
(Analog) voltage output See "Analog output (function)".
A
Auto preset
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.
B
Bottom value indication (mode) Shows the minimum pressure reached at that moment.
Chattering
The phenomenon caused in the switch output type in which the output turns on
and off repeatedly at high frequency.
Chattering-preventing function
A function to delay the response time of switch output in order to prevent
chattering.
C
Copy function
A function to copy a pressure setting value and function setting (excluding fine
adjustment of indication value).
D
Digit (Min. setting unit)
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 1kPa, e.g., 1, 2, 3, …, 99, 100.
E
Error indication
With the self-diagnosis function given to the Pressure switch, it indicates that
there is a failure which could cause a switch failure.
Fine adjustment mode See "Fine adjustment of indicated value".
Fine adjustment of indicated
value
An indicated pressure value can be adjusted within the range of ±5% R.D.
(±5% of the indicated value). It is used if a true pressure value is known or to
correct the difference of an indicated value of the measurement equipment
nearby that measures the same pressure as the Pressure switch.
F.S. (full span/full scale)
Abbreviation for full span and full scale; means the maximum fluctuation range
of the Pressure switch rated value. For example, when the output voltage is 1
to 5[V], the F.S. will be 5-1
= 4[V]. (Reference: 1%F.S. = 4 × 0.01 = 0.04[V])
F
Function selection mode
It is a mode with which each function is set up, and it is a separate menu from
the pressure setup. If the setting needs to be changed at factory, "F*", each
item can be set up. The items to be set up are: indication color, operation
mode, output type, response time, indication resolution, fine adjustment of
indicated value, use of auto preset, use of power-saving mode, and use of PIN
number.
Hysteresis
Difference between the points at which the Pressure switch is turned on and
off.
H
Hysteresis mode Refer to "List of output mode" on page 29.
Indication accuracy Shows the deviation between displayed pressure value and the true pressure. I
Indication color
The color of the digital display. There are four choices: usually green, usually
red, green (off) to red (on), and red (off) to green (on).
