Hence, judgment by the sensor is as accurate as before the reference pressure change.

Optimum for leak test Leak test mode This mode is optimally suitable for a leak test since Comparative Output 1 can be set to the hysteresis mode and Comparative Output 2 can be set to the window comparator mode. Forced output mode Suitable for start-up check The comparative outputs are forcibly maintained in the OFF state in the sensing mode, irrespective of the set values. Also, since the comparative outputs can be forcibly made ON or OFF with key operation, without actually applying pressure, this mode is suitable for an operation check or a start-up check. 3 Hysteresis (Variable) Comparative ON Output 1 OFF Hysteresis Hysteresis (Fixed) (Fixed) MODE key Press MODE Selection can be made according to mounting method or place of use.

Direct mounting on a wall Selection from six pressure units Analog bar display Peak hold / bottom hold display The pressure unit can be selected from six different systems to suit your requirement. The selectable pressure units differ with the sensor type. When the pressure unit is changed, the measured pressure value and the set values are automatically converted. Pressure changes can also be displayed in an analog fashion using LED bars. Hence, sudden pressure changes can be recognized at a glance. LED bars indicate the pressure level in steps of 10 % F.S., regardless of the pressure unit. The peak value or the bottom value of the varying pressure can be displayed. This function is convenient for finding the pressure variation range or for determining a reference for pressure settings.

The vacuum type can be mounted close to the chip mounter suction head since it weighs only 70 g. Air-leak test for PET bottles Leak test mode, which is an output mode optimally suitable for an air-leak test, has been incorporated. It can reliably detect even a small air-leak. Because of the auto-reference function, it is safe even if the filling pressure varies.

Please note that pressing down on the MODE key for an extended moment will enable the key-protect function as soon as the key is released. • If using the window comparator mode, set the pressure values so that there is a difference of 3 digits, or more, between Set Value 1 (P-1) and Set Value 2 (P-2), and between Set Value 3 (P-3) and Set Value 4 (P-4). No output will be possible with a 0 to 2 digit difference. Wiring • Make sure that the power supply is off while wiring. • 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 power supply 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 equipment to an actual ground. • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction. Conditions in use for CE conformity • The DP3 series is a CE conformity product complying with EMC Directive. The harmonized standard with regard to immunity that applies to this product is EN 61000-6-2 (Note) and the following condition must be met to conform to that standard. Condition • The sensor should be connected less than 10 m 32.808 ft from the power supply. Note: The EN 50082-2 that previously applied to the products for conforming to EMC Directive was replaced by EN 61000-6-2 staring April 1st, 2002. Others • Use within the rated pressure range. • Do not apply pressure exceeding the pressure withstandability value. The diaphragm will get damaged and correct operation shall not be maintained. • Do not use during the initial transient time (0.5 sec.) after the power supply is switched on. • Avoid dust, dirt, and steam. • Take care that the sensor does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc. • Do not insert wires, etc., into the pressure port. The diaphragm will get damaged and correct operation shall not be maintained. • Do not operate the keys with pointed or sharp objects.

Settable range and set pressure range after correction • The settable range of Set Value 3 (P-3) and Set Value 4 (P-4) is wider than the rated pressure range to cater to the auto-reference function. • At the time of auto-reference input, if the corrected set value exceeds the set pressure range, the set value is automatically corrected to be within the set pressure range. Hence, please see that the set pressure range is not exceeded.

Pressure DP4 ON • When the power supply is switched on again, the auto-reference input value [Set Value 5 (P-5)] is set to zero. • Although it is not possible to display the corrected Set Value 3 (P-3’) and Set Value 4 (P-4’), it is possible to display the autoreference input value [Set Value 5 (P-5)]. • In case the auto-reference input (pink) is not used, make sure to connect it to V (brown). Time 1. By making the auto-reference input ‘Low’ when the PCB mount components are not being sucked, the reference pressure value is recorded in Set Value 5 (P-5), and Set Value 3 (P-3) and Set Value 4 (P-4) are corrected. 2. Suction confirmation is done by Comparative Output 2, 7.5 ms, 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 of Comparative Output 1. If the nozzle is OK, Comparative Output 1 is OFF, and if it is NG, Comparative Output 1 is ON. ( ) ( ) (2) Air-leak test for PET bottles (Using leak test mode) • The effect of dispersion in the filling pressure of the PET bottle is eliminated by using the auto-reference function. • Comparative Output 1 is used to detect the filling pressure, while Comparative Output 2 is used to detect the leakage. Since Comparative Output 1 is not affected by the auto-reference input function, the filling pressure is detected with reference to the atmospheric pressure.

If used in a transient state, it will result in wrong operation. • Use Comparative Output 2 at least 7.5 ms after the autoreference input is made low. • At the time of auto-reference input, is displayed on the 31/2 digit LED display for 1 sec. approx., the pressure at that instant is stored temporarily in Set Value 5 (P-5), and Set Value 3 (P-3) and Set Value 4 (P-4) are corrected. • Since Set Value 5 (P-5) and the corrected Set Value 3 (P-3’) and Set Value 4 (P-4’), after the auto-reference input, are not stored in an EEPROM, they are erased when the power is switched off. 816 NG product 0 1 ms or more Comparative Output 2 (ON / OFF) P-3’P-3P-5 OK product P-4 Low level input time P-4’P-4P-5 b a P-5 P-2 P-1 1. Pressure is increased in the PET bottle, and when Set Value 2 (P-2) 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 is made ‘Low’. The filled pressure is recorded in Set Value 5 (P-5) as the reference value, and Set Value 3 (P-3) and Set Value 4 (P-4) are corrected. 3. The leakage is measured by Comparative Output 2, 7.5 ms, or more, after the application of the auto-reference input. If the leakage is OK, Comparative Output 2 is ON, and if it is NG, Comparative Output 2 is OFF. ( ) If it is a simple air-leak test, it can be done by directly applying the Comparative Output 1 signal (falling signal) to the autoreference input.

Forced output mode • In the initial setting, if the output mode is set to the forced output mode ( ), Comparative Output 1, 2 are forcibly maintained at OFF level in the sensing mode, irrespective of Set Value 1 to 4 (P-1 to P-4). Hence, this mode is useful when it is desired to only display the pressure value without using the comparative outputs. Further, if the keys are operated as per the procedure given below, Comparative Output 1, 2 can be forcibly switched either ON or OFF without applying pressure at the pressure port. This is convenient for an operation check of Comparative Output 1, 2 or for an inspection before commencing work.
