In case of DP3...operation efficiency UP!Since the threshold level can be automatically changedby the auto-reference function, two suction nozzles canbe used, alternately, with one sensor.

Till now...one sensor was required for each suctionnozzleSince the threshold level differs with the suction nozzle, asensor was required for each suction nozzle, increasingthe cost significantly.

• Unaffected by changes in reference pressureBy an external signal, the set (threshold) values are corrected by being shifted by an amount equal to thepressure change. Hence, judgement by the sensor is as accurate as before the reference pressure change.This function is extremely suitable in places havingintense variations in the reference pressure or wherefine settings are required.

The pressure unit can be selected fromsix different systems to suit yourrequirement.

The selectable pressure units differwith the sensor type. When the pres-sure unit is changed, the measuredpressure value and the set valuesare automatically converted.

Pressure changes can also be dis-played in an analog fashion using LEDbars. Hence, sudden pressure changescan be recognized at a glance.

LED bars indicate the pressure levelin steps of 10% F.S., regardless ofthe pressure unit.

A Wide Variety of Models

High Accuracy • High Resolution • High Speed

Hysteresis modeThe hysteresis of the comparative outputs can be set, as desired, with theset values.

Window comparator modeThe comparative outputs can be madeON or OFF by a pressure within the setrange.Since Comparative Output 1 can be usedas a self-diagnosis output, it is possibleto specify the auto-reference input range.

Note: The auto-reference function acts only on Set Value 3 (P3) and Set Value 4 (P4) of Comparative Output 2.

Forced output modeThe comparative outputs are forciblymaintained in the OFF state in thesensing mode, irrespective of the setvalues.Also, since the comparative outputs can be forcibly made ON or OFF withkey operation, without actually applyingpressure, this mode is suitable for anoperation check or a start-up check.

Leak test modeThis mode is optimally suitable for aleak test since Comparative Output 1can be set to the hysteresis mode andComparative Output 2 can be set to thewindow comparator mode.

It achieves a 2.5ms, or less, responsetime at a high resolution of 1/1,000.It enables highly accurate sensing with itsexcellent repeatability and temperaturecharacteristics.

The peak value or the bottom value ofthe varying pressure can be displayed.This function is convenient for findingthe pressure variation range or fordetermining a reference for pressuresettings.

Selection can be made according tomounting method or place of use.

Note: The response time is 7.5ms, or less, at thetime of auto-reference input.

• Do not use during the initial transient time (0.5 sec.) afterthe power supply is switched on.

• Avoid dust, dirt, and steam.• Take care that the sensor does not come in direct contactwith water, oil, grease, or organic solvents, such as,thinner, etc.

• Do not insert wires, etc., into the pressure port. Thediaphragm will get damaged and correct operation shallnot be maintained.

• Do not operate the keys with pointed or sharp objects.

Wiring• Make sure to carry out the wiring in the power supply offcondition.

• Verify that the supply voltage variation is within the rating.• If power is supplied from a commercial switching regulator,ensure that the frame ground (F.G.) terminal of the powersupply is connected to an actual ground.

• In case noise generating equipment (switching regulator,inverter motor, etc.) is used in the vicinity of this sensor,connect the frame ground (F.G.) terminal of the equipmentto an actual ground.

• Do not run the wires together with high-voltage lines orpower lines or put them in the same raceway. This cancause malfunction due to induction.

DP3PRECAUTIONS FOR PROPER USE

Setting

• If key-protect has been set, make sure to release key-protect before operating the keys. (Please refer to ‘Key-protect function ’ on P.719 for the procedure.)

• Set Value 1 to 4 (P1 to P4) can be made common for all the output modes.• In the positive pressure type sensor, Set Value 2 (P2) and Set Value 4 (P4) can be set only towards the high pressure side

with respect to Set Value 1 (P1) and Set Value 3 (P3), respectively.In the vacuum pressure type sensor, Set Value 2 (P2) and Set Value 4 (P4) can be set only towards the high vacuum sidewith respect to Set Value 1 (P1) and Set Value 3 (P3), respectively.

• Auto-reference function acts on Set Value 3 (P3) and Set Value 4 (P4) only.• Set Value 5 (P5) is the auto-reference input value. If auto-reference input is not applied, Set Value 5 (P5) is zero.• The conditions which are set are stored in an EEPROM. Kindly note that the EEPROM has a life span and its guaranteedlife is 100,000 write operation cycles. However, since the auto-reference input value [Set Value 5 (P5)] is not written intothe EEPROM, it is not included in the number of write operation cycles.

1. Pressure is increased in the PET bottle, and when Set Value 2(P2) is reached, Comparative Output 1 is turned ON and the filling is tightly shut off.

2. After shutting off the filling pressure, the auto-reference input ismade ‘Low’. The filled pressure is recorded in Set Value 5 (P5)as the reference value, and Set Value 3 (P3) and Set Value 4(P4) are corrected.

3. The leakage is measured by Comparative Output 2, 7.5ms, ormore, after the application of the auto-reference input.If the leakage is OK, Comparative Output 2 is ON, and if it isNG, Comparative Output 2 is OFF.

1. By making the auto-reference input ‘Low’ when the PCB mountcomponents are not being sucked, the reference pressure valueis recorded in Set Value 5 (P5), and Set Value 3 (P3) and SetValue 4 (P4) are corrected.

2. Suction confirmation is done by Comparative Output 2, 7.5ms,or more, after the application of the auto-reference input.If suction is OK, Comparative Output 2 is ON, and if it is NG,Comparative Output 2 is OFF.

3. Error due to suction nozzle clogging is detected by the setting ofComparative Output 1. If the nozzle is OK, Comparative Output 1 is OFF, and if it is NG,Comparative Output 1 is ON.

Auto-reference functionPrinciple

• Auto-reference function corrects Set Value 3 (P3) and Set Value 4(P4) of Comparative Output 2 by taking the pressure measured atthe time of auto-reference input as the reference pressure.

Pressure

• When there is no auto-reference input, the atmospheric pressureis taken as the reference pressure for Set Value 3 (P3) and SetValue 4 (P4).

• At the time of auto-reference input, the pressure value detected atthat instant is temporarily recorded as Set Value 5 (P5) andbecomes the reference pressure.

• With Set Value 5 (P5) as the reference pressure, Set Value 3 (P3)and Set Value 4 (P4) are automatically corrected to ‘Set Value 3(P3)`Set Value 5 (P5)’ and ‘Set Value 4 (P4)`Set Value 5(P5)’, respectively.

Settable range and set pressure range after correction

• The settable range of Set Value 3 (P3) and Set Value 4 (P4) is widerthan the rated pressure range to cater to the auto-reference function.

• At the time of auto-reference input, if the corrected set valueexceeds the set pressure range, the set value is automaticallycorrected to be within the set pressure range. Hence, pleasesee that the set pressure range is not exceeded.

1ms or more

7.5ms or less

• Maintain the pressure at a constant level for at least 1ms after theauto-reference input is made Low. If used in a transient state, itwill result in wrong operation.

• Use Comparative Output 2 at least 7.5ms after the auto-referenceinput is made low.

• At the time of auto-reference input, is displayed on the 31/2digit LED display for 1 sec. approx., the pressure at that instant isstored temporarily in Set Value 5 (P5), and Set Value 3 (P3) andSet Value 4 (P4) are corrected.

• Since Set Value 5 (P5) and the corrected Set Value 3 (P3’) andSet Value 4 (P4’), after the auto-reference input, are not stored inan EEPROM, they are erased when the power is switched off.

• When the power supply is switched on again, the auto-referenceinput value [Set Value 5 (P5)] is set to zero.

• Although it is not possible to display the corrected Set Value 3(P3’) and Set Value 4 (P4’), it is possible to display the auto-reference input value [Set Value 5 (P5)].

• In case the auto-reference input (pink) is not used, make sure toconnect it to `V (brown).

Application examples

(2) Air-leak test for PET bottles (Using leak test mode)

• Pressure judgement errors due to suction nozzle type, suctionnozzle clogging, reference pressure changes, etc., are eliminatedby the auto-reference function.

• The confirmation of PCB mount component suction is done withComparative Output 2, which is acted upon by the auto-referencefunction, and error due to nozzle clogging is simultaneouslydetected by Comparative Output 1.

(1) Confirmation of PCB mount component suction (Using hysteresis mode)

• The effect of dispersion in the filling pressure of the PET bottle iseliminated by using the auto-reference function.

• Comparative Output 1 is used to detect the filling pressure, whileComparative Output 2 is used to detect the leakage. SinceComparative Output 1 is not affected by the auto-reference inputfunction, the filling pressure is detected with reference to theatmospheric pressure.

Peak hold & bottom hold functions Forced output mode

Key-protect function

• Peak hold and bottom hold functions enable the display ofthe peak value (maximum pressure value in case of thepositive pressure type sensor and maximum vacuum pres-sure value in case of the vacuum pressure type sensor)and the bottom value (minimum pressure value in case ofthe positive pressure type sensor and minimum vacuumpressure value in case of the vacuum pressure type sen-sor) of the varying measured pressure.

• These functions are convenient for finding the pressurevariation range or for determining the reference for pres-sure settings.

• Please note that the peak value and the bottom value data iserased when it is no longer displayed.

• The response time of the comparative outputs becomes slowerduring the peak hold and bottom hold display.

• In the initial setting, if the output mode is set to the forced outputmode ( ), Comparative Output 1, 2 are forcibly maintained atOFF level in the sensing mode, irrespective of Set Value 1 to 4(P1 to P4). Hence, this mode is useful when it is desired to onlydisplay the pressure value without using the comparativeoutputs.Further, if the keys are operated as per the procedure givenbelow, Comparative Output 1, 2 can be forcibly switched eitherON or OFF without applying pressure at the pressure port. Thisis convenient for an operation check of Comparative Output 1, 2or for an inspection before commencing work.The figure below is for a vacuum pressure type sensor with theunit set to ‘kPa’ ( ).
