8. Detection Mode Operation
■ General-purpose mode (F-1)
This mode allows the user to configure 2 detection points.
Control output 1: Turns ON when pressure exceeds setting P1.
Control output 2: Turns ON when pressure exceeds setting P2.

*Hysteresis when operating in general-purpose mode and application
modes 1 and 2 is 0.5% of F.S. in the standard and high-speed modes.
During focus mode operation, it is 0.1% of F.S.
■ Variable hysteresis mode (F-2)
Two detection points may be user-configured, and hysteresis for both
may also be set.
Control output 1: Turns ON when pressure exceeds setting P1. Turns OFF
when pressure drops the selected hysteresis amount
below P1.
Control output 2: Turns ON when pressure exceeds setting P2. Turns OFF
when pressure drops the selected hysteresis amount
below P2.

■ Window mode (F-3)
The user may select a pair of upper (Hi) and lower (Lo) thresholds, and
the sensor turns OFF when the pressure falls outside of the resulting
range.
*Control output 1 is 0.5% of F.S. during standard and high-speed
operation, it has a hysteresis of 0.1% of F.S. in the focus mode, and
control output 2 has a hysteresis of 0.

■ Application mode 1 (A-1)
This detection mode is optimum for use in suction detection applica-
tions.
Recommended heads: AP-41/41M/44
Control output 1: Suction pressure detection.
Turns ON when pressure exceeds setting P1.
Control output 2: Detection of vacuum burst pressure (or confirmation of
vacuum arrival pressure).
Turns ON when the pressure falls below setting P2. May
be set during focus mode operation, although there are
restrictions on the setting range.
Zero shift: Shifts the zero point immediately after setting the zero
shift timer once zero shift input is received.
P1: Pressure setting for control output 1.
T1: Zero shift timer setting (ms) < Variable between 0 and 1,999 ms
P2: Pressure setting for control output 2.
*P2 is unrelated to zero shift and is always based on the current ambi-
ent pressure.

■ Application mode 2 (A-2)
This mode is optimum for use in leak test applications.
Recommended head: AP-43
Control output 1: Leak pressure detection.
Turns ON when pressure falls below setting P1.
*Output only when receiving zero shift input.
Control output 2: Window comparator output for detection of fill pressure.
Turns OFF when pressure falls outside the range deter-
mined by upper (Hi) and lower (Lo) thresholds. Fill pres-
sure values are displayed with the center pressure as 0
during focus mode operation.
P1: Pressure setting for control output 1.
Hi: Upper threshold setting for control output 2.
Lo: Lower threshold setting for control output 2.
*The Hi and Lo values are unrelated to zero shift and are always based
on the current ambient pressure.

6. Connection Method and Diagrams
Insert the included connector-tipped cable into the sensor's connector.
Position the connector so that the side of the connector where the metallic
contacts are visible is facing up.

7. Precautions for Safe Use
Follow these guidelines. Failure to do so may result in product damage.
CAUTION
■ Connections
● Always ground the frame ground terminal when using an off-the-shelf
switching regulator.
● Use separate conduits for power line and high voltage lines, since use
of a common conduit may result in device malfunction caused by noise.
● Improper wiring may result in the device becoming excessively hot or
in device damage.
■ Notice about CE marking
● Attach the ferrite core (OP-87505) if you extend a sensor head cable/
amplifier power cable to 3 m or more to use.
(Attachment position: within 100 mm from the amplifier unit of a
power cable, Number of turns: 2)
■ Other
● Do not use this sensor with corrosive gasses or liquids.
● Do not insert objects such as wire into the pressure insertion area.
Doing so may result in the device failing to operate properly due to
damage to the pressure-sensitive elements.
● Do not use sharp-tipped objects to press the setting keys.
