Error message

Cause

Corrective action

Overcurrent due to short-

circuit.

Pressure is being applied

during zero-point adjust-

ment.

Applied pressure

exceeds the upper

limit of displayable

pressure range.

Applied pressure

exceeds the lower

limit of displayable

pressure range.

Applied pressure

Applied pressure

exceeds the upper

limit of displayable

pressure range.

Switch off the power supply

and check the load.

Applied pressure at the

pressure port should be

brought to atmospheric pres-

sure and zero-point adjust-

ment should be done again.

Applied pressure should be

brought within the rated

pressure range.

Error messages

• When an error occurs, take the following corrective action.

• This product is not a safety sensor. Its use is not

intended or designed to protect life and prevent

body injury or property damage from dangerous

parts of machinery. It is a normal pressure

detection sensor.

• The DP2 series is designed for use with non-

corrosive gas. It cannot be used with liquid or cor-

rosive gas.

• The DP2 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.

Conditions in use for CE conformity

Condition

• If setting is impossible even with pressing the MODE key,

verify whether the key-protect function is enabled. 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

value so that there is a difference of 3 digits, or more,

between Set Value 1 (P-1) and Set Value 2 (P-2). No

output will be possible with a 0 to 2 digit difference.

Operation

Wiring

The analog voltage output does not incorporate a short-

circuit protection circuit. Do not directly connect a power

supply or a capacitive load.

• 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.

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 starting April 1st, 2002.

Displays measured pressure, settings, error

messages and key-protect status.

Lights up when Comparative Output 1 is ON.

Lights up when Comparative Output 2 is ON.

• In the initial setting mode, pressing the

key changes the settable digit.

• In the Set Value 1, 2 modes, pressing

the key changes the set value to the

high pressure side in case of positive

pressure type sensor and to the high

vacuum side in case of vacuum pres-

sure type sensor.

• In the sensing mode, if the key is

pressed continuously for 4 sec. or more,

the display shows peak hold value.

• In the initial setting mode, pressing the

key changes the set conditions.

• In the Set Value 1, 2 modes, pressing

the key changes the set value to the

low pressure side in case of positive

pressure type sensor and to the low

vacuum side in case of vacuum pres-

sure type sensor.

• In the sensing mode, if the key is

pressed continuously for 4 sec. or more,

the display shows bottom hold value.

• Each press of the key changes the selected

mode to sensing mode, Set Value 1 (P-1) set

mode and Set Value 2 (P-2) set mode.

• In the sensing mode, if the key is pressed

continuously for about 3 sec., key-protect can

be set / released.

• In the sensing mode, if the mode selection

key is pressed while pressing the increment

key (

), the initial setting mode is obtained.
