PIPING/MOUNTING

• You can select from three	Hexagonal socket bolt
pressure port positions by
selecting or replacing the
pressure ports. Select the
optimal position based on

your location.

	CAUTION	* The arrow shows the pressure port
		positions that can be selected.

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.

•An Rc (PT) 1/8 internal thread is provided on the pressure port of the AP-30 series. Commercially available air-pressure pipe joints or 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).

Hold this part with a wrench (14 mm).

•Be sure to block an unused pressure port with the hexagonal-socket port stopper provided.

CAUTION

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.

• 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.

socket bolts

CAUTION

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.

CAUTION

■ Connection

•When using a commercially available switching regulator, be sure to ground the frame ground terminals.

•Isolate the sensor’s wiring from power lines or high-voltage lines; otherwise, the sensor may malfunction due to noise interference.

■ Other

•Do not use the AP-30 series for the detection of corrosive gases or liquid.

•Do not insert any objects, such as wires, from the pressure port.

The pressure-sensing element may break, resulting in malfunctions.

•Do not press the front panel keys with a pointed object.

•The AP-30 series does not have an explosion-proof structure. Do not use it for the detection of flammable gases.

OPERATION MODE SELECTION

■ 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.

	Pressure	* The stability levels are
	A	automatically set as
	SH	shown in the following

	b	SH = (A + C)
	0

Control output 1 ON	2
(OUT 1)OFF								SL =	(C + b)
Control output 2 ON
(OUT 2)OFF								2

■ 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).

■ 2-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.

■ 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.

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.
