PIPING/MOUNTING

?Special mounting brackets are

included with the AP-30 series.

Use the type of mounting bracket

appropriate for the location

where the sensor is mounted. To

mount the sensor, remove the

hexagonal socket bolts and then

retighten them through the

mounting bracket.

The maximum tightening torque for the hexagonal socket bolt is

0.3 Nm (Approx. 3 kgf?cm). To avoid breakage, do not exceed the

specified value.

SAFETY PRECAUTIONS

Be sure to follow the instructions below to avoid malfunctions.

?You can select from three

pressure port positions by

selecting or replacing the

pressure ports. Select the

optimal position based on

your location.

0.3 Nm (Approx. 3 kgf?cm). To avoid breakage, do not exceed the

specified value.

nipples can be used.

?When connecting a joint or a plug,

use a wrench (14 mm) to hold the

metallic part as shown in the figure to

avoid a large force being applied to

the sensor housing (resin part).

port stopper provided.

The maximum tightening torque for the hexagonal-socket port

stopper is 10 Nm (Approx. 100 kgf?cm). To avoid breakage, do not

exceed the specified value.

?To prevent air leaks, wrap the male screw with sealing tape.

?To mount the AP-30 series to a panel using the panel mounting

holder set (OP-31357), use a panel with 1 to 3.5 mm thickness.

OPERATION MODE SELECTION

s Auto-tuning mode (F-1)

Using the AUTO key, detect the upper limit value (A) and the lower

limit value (b). The detection level (C) is automatically set at the

midpoint between the two values. (You can finely adjust the preset

value C within the range between A and b.)

Control output 1:The sensor turns on when the pressure exceeds the

preset value C.

Control output 2:The sensor turns on when the pressure goes outside

the stability levels.

*The stability levels are

automatically set as

shown in the following

calculations.

s Hysteresis mode (F-2)

Set desired detection level (H) and hysteresis (h) for the detection.

Control output 1:The sensor turns on when the pressure exceeds the

preset value H. When the pressure falls by the preset

value h, the sensor turns off.

Control output 2:The sensor turns on when the pressure goes outside

the hysteresis width (H - h).

h: Hysteresis width of

OUT1

*When h is set to a

value close to 0, if

pressure fluctuates

around the detection

point, OUT1 will

chatter.

s2-independent mode (F-3)

Set two desired detection points (A and B).

Control output 1:The sensor turns on when the pressure exceeds the

preset value A.

Control output 2:The sensor turns on when the pressure exceeds the

preset value b.

s Window mode (F-4)

Set desired upper limit value (H) and lower limit value (L).

Control output 1:The sensor turns off when the pressure goes outside

of the range between the upper limit value (H) and

lower limit value (L).

Control output 2:The sensor turns off when the pressure goes outside

of the stability levels.

The stability levels are

automatically set as

shown in the following

calculations.

Note 1: The above description shows the operation of control outputs

1 and

2 when the output selector switch is set to N.O.

When the output selector switch is set to N.C., the operation of control

outputs 1 and 2 is inverted.

Note 2: Except for OUT1 in hysteresis mode, each control output

includes an internal hysteresis of 0.5% of F.S.

ADJUSTMENT

At normal atmospheric pressure (1 atm.), press A

seconds in measurement mode. The display changes to “----“, then to “0”. The zero adjustment function can be used when the pressure is within ±5% of F.S.Note 2: When units of psi are selected with the AP-34Z, the display range becomes 19.99 to 19.99.

Note 3: Perform the zero-shift adjustment periodically.

Note 4: The initial output voltage may fluctuate by ±1.0% immediately after the power is turned on. To measure minute differences in pressure, let the sensor warm up for approximately 15 to 30 minutes.

Applied pressure was outside of the display range.

Zero-point adjustment was executed at a pressure of ±5% or more of F.S.Worldwide Headquarters KEYENCE CORPORATION

OTHER FUNCTIONS AND ERROR INDICATION

s Peak-hold/bottom-hold display function

The AP-30 series internally updates the peak-hold and bottom-hold values at all times.

q To display hold values

?While v is held down in measurement mode, the peak-hold value ?While w is held down in measurement mode, the bottom-hold value q To reset the peak-hold and bottom-hold values ?Hold down v and press w in measurement mode.

q The peak-hold and bottom-hold values are also reset using the following procedure.?Turn the power off.

?Note: The hold values cannot be displayed when the front panel keys are locked with the key protection function. Disable the function before displaying the hold values.

s Analog output function (Except for Z type)

The voltage value according to the pressure value is output.

s Error indications and remedies

s Zero-shift function (Z type only)

The zero-shift function is used to reset the current pressure value to “0” using an external signal input, in order to prevent measurements from being affected by fluctuations in base pressure.

Example: Leakage test

Input a zero-shift value after air supply is completed so that air leakage after a specified time is displayed as a negative value. The AP-30’s detection is unaffected by fluctuations in air supply volume.

When the power is turned off, the value updated after the zero-shift input (zero-shift value) is lost.

Note 1: The zero-shift function cannot be used in auto-tuning mode.Note 2: The zero-shift input is effective when the current pressure is between -3% of F.S. and F.S. for a shift of 0 (P = 0).

Note 3: If the applied pressure is outside the range of -15% to 110% of the rated pressure, “-FFF ” or “ FFF ” appears.

s Key protection function

The key protection function is used to lock the front panel key in order to prevent preset values from being accidentally changed.

To enable the key protection function, hold down A and press v .“Loc ” flashes for 2 seconds and the keys are locked.

To disable the key protection function, again hold down A and press w . “unL ” flashes for 2 seconds and the keys are https://www.360docs.net/doc/c014899015.html,ing the EEPROM, the AP-30 series can retain the preset values even if the power is turned off.

s Display color selection

You can set the color of the LED display either to the two-color mode which displays the numerical value in green or red according to OUT1,or to the single color mode which always shows the value in red. The two-color display allows you to check the output condition at a glance.(Refer to “ADJUSTMENT ” on page 3 for the setting procedure.)In two-color mode (Regardless of N.O./N.C. selection)?When OUT1 is turned on: Red ?When OUT1 is turned off: Green

s N.O./N.C. selection

The N.O. or N.C. output can be selected according to the device ’s control method. When the output status is changed, the color of the numerical value display LED is inverted.

s Chattering prevention function

The chattering prevention function is used to prevent outputs from chattering by changing the response time. The response time can be selected from 4 settings. When the detection (non-detection) state continues for more than a preset response time, the output is pro-duced.
