Terms Meaning
H
Hysteresis
The difference between the pressure switch ON and OFF points, used to
prevent chattering.
Hysteresis mode Refer to "List of output modes" on page 27 .
I Indicator LED The LED that turns on when the switch output is on.
Insulation resistance
Insulation resistance of the product itself. The resistance between an
electricical circuit and the pressure switch body.
K
Key lock (function)
A function that locks the setting buttons so that no accidental setting changes
can be made.
L Load impedance Refer to "Max. load impedance".
Low-cut function
Function to prevent display flicker at atmospheric pressure.
0 is displayed for pressure when the pressure is near atmospheric pressure.
M
Manual set up
Manual pressure set up without using auto preset. This term is used to
distinguish from the pressure set up using auto preset.
Master Pressure switch A Pressure switch whose settings are copied when using the copy function.
Max. applied voltage
The maximum value of applied voltage available to the output wire of the NPN
output.
Max. load current The maximum current available to the output wire of the switch output.
Max. (Min.) load impedance
The maximum (minimum) load (resistance value and impedance) which can be
connected to the output (output wire) of the analogue current output.
Measurement mode
The condition in which the pressure is detected and displayed and the switch
output is operating.
Min. setting unit Refer to "digit".
N
Normal output
The switch output operation in which the switch is turned on when pressure
equal to or greater than the set value is detected. In the (hysteresis mode)
window comparator mode, it is the operation in which the switch is turned on
when pressure is within the switch output range (P1L to P1H or P2L to P2H).
(Refer to "List of output modes" on page
27 .)
NPN (open collector) output The switch output which uses the NPN transistor for output.
O Operating mode There are two choices, hysteresis mode and window comparator mode.
Output impedance
The resistance value of a component between the voltage output element and
the analogue voltage output. It is indicated as a resistance value which is
converted in accordance with the condition in which resistance is directly
connected to the voltage output element. There may be an error in the output
voltage depending on this output impedance and the input impedance of
customers' equipment. (example: If the Pressure switch with output impedance
of 1
kΩ is connected to the A/D converter to detect the analogue output of 5 V,
the detected voltage by the A/D converter becomes 5(V) ×
1(MΩ)/(1(kΩ) +
1(MΩ)) ≒
4.995(V), and there is an error of approximate 0.005 V).
Output type
The operation type of the switch output. Either normal output or reversed
output can be selected. (Refer to "List of output modes" on page
27 .)
