Functions
Pressure unit change function
PSAN-V01C(P) and PSAN-C01C(P) has 7 kinds of pressure
unit, PSAN-01C(P) and PSAN-1C(P) has 5 kinds of pressure
unit. Please select the proper unit for application.
• PSAN-V01C(P), PSAN-C01C(P)
: kPa, kgf/cm², bar, psi, mmHg, inHg, mmH
• PSAN-01C(P), PSAN-1C(P) : MPa, kPa, kgf/cm², bar, psi
※ When using mmH
O unit, multiply display value by 100.

Output mode change function
There are 5 kinds of control output mode in order to realize
the various pressure detection.
• Hysteresis mode [ HYsM
HYsM ]
When needed to change hysteresis for detecting pressure.
• Window comparison output mode [ WIN
When needed to detect pressure in certain area.
• Hysteresis - Window comparison output mode [ HY-W
When both hysteresis mode and window comparison output
mode are required.
• Automatic sensitivity setting mode [ AUTO
When needed to set detection sensitivity automatically at
proper position.
• Forced output control mode [ fOUT
When needed to display pressure with remaining comparison
output OFF regardless of setting value.
Control output change function
Type of control output for Out1 and Out2 can be able to set
Normally Open or Normally Closed.
※ Note that Normally Open and Normally Closed provide
opposite output.

Response time change function
(Chattering prevention)
It can prevent chattering of control output by changing
Response time . It is able to set 5 kinds of Response
time (2.5ms, 5ms, 100ms, 500ms, 1000ms) and if the
Response time is getting longer, the detection will be more
stable by increasing the number.
Analog output scale setting function
• Analog voltage output scale setting
The scale function for analog output voltage (1-5VDC) is not
fixed to the rated pressure range. It can be changed for User's
application. Analog output voltage range will be fixed to 1-5VDC
within the pressure range from pressure point of 1VDC output (
A-1V) to pressure point of 5VDC output ( A-SV).
• Analog current output scale setting
The scale for analog output Current (DC4-20mA) is not fixed
to the rated pressure range. It can be changed for User's
application. Analog output voltage will be fixed to 4-20mA within
the rated pressure range from pressure point of 4mA output(
A-04) to pressure point of 20mA output ( A-20).

Hold/Auto shift input setting function
• Hold function
A function to hold present pressure value and control
output at the time of hold signal input.
※ Present pressure value and Hold message will flash
in turn every 0.5 sec. while Hold function is set. Make
sure that Hold function is not able to execut while forced
output mode is executed.
▶ Control output timing chart
When Hold signal is applied in Hysteresis mode, refer to
'
Control output diagram' of E-8 page.

• Auto shift function
A function to use the measured pressure at the moment of auto
shift input as a reference pressure in order to correct the set
point values of control output when initial pressure changes.
※ Reference pressure is fi xed to atmospheric pressure (0.0kPa)
when Auto shift function is not used.
※ ShIN(Auto shift compensation value) will be reset to 0
when changing control output or preset values.
※ Auto shift function will not be executed if " HHHH" or
" LLLL" error occurs or if forced output mode is set.
[ ShOT ] : Reference pressure change through setting.
[ OUT1 ] : Changed reference will be applied to control output 1 only.
[ OUT2 ] : Changed reference will be applied to control output 2 only.
[ ALL ] : Changed reference will be applied to both control
output 1 and control output 2.
