Two independent outputs can be set.

(2) Setting mode

ON point / OFF point: Each output can be set in the range from 0 to the rated value. Set value: 0 to rated value

Output configuration: Each output can be set as normally open (NO) or normally closed (NC).

Setting: NO <> NC

Hysteresis:

Each output can be set at 10% of the range from 0 to the rated value. (Effective in

window mode and 2-point auto-teaching mode.) Setting range: (0 to rated value) x 10%

Auto-teaching

When the auto-teaching mode is used, measured values can be input as ON point or OFF point set values

instead of key inputs. Two types of auto-teaching are available: 1-point auto-teaching, where only one single

point is set, and 2-point auto-teaching, where two points are set.

(1) 2-point auto-teaching (Hysteresis mode teaching)

This function automatically sets the ON point and OFF point for the comparative output by designating a point

with no object (TEACH 1) and a point with an object (TEACH 2) using actual objects. The outputs are made in

hysteresis mode. The hysteresis is a set value.

TEACH 2

The set value is the mid-point between TEACH 1 and TEACH 2.

Example: If TEACH 1 is 0.25 kPa and TEACH 2 is 0.95 kPa, the ON point set value = (0.95+0.25)/2 = 0.60

(2) 1-point auto-teaching (Window mode teaching)

This function automatically sets the ON point and OFF point for the comparitive output by inputing a reference

point (TEACH 1) using an actual object. The function operates only when an object exists. The outputs are

made in the window mode. The hysteresis width and window width are set values. (The window width set value

is valid only when 1-point teaching is set. Setting range: (0 to rated value) x 30%)

(TEACH 1)

The ON point and OFF point set values are set at the reference point ±window width.

Example: If the reference point (TEACH 1) is 0.90 kPa and the window width is 0.50 kPa,

the ON set value = (0.90 - 0.50)/2 = 0.20 and the OFF point set value = (0.90+0.50)/2 = 0.70.

pressure display

Error display

(1) Pressure warning during zeroing:

Error display and warning if excess pressure or flow (exceeding rated value ±5%) is applied during zeroing.

(2) Teaching error display:

Warning if teaching is unsuccessful.

(3) Short-circuit protection and display:

If overcurrent flows in a connected load, the abnormal status is notified by an error display and the OUT LED,

for the corresponding output, flashing. Transistor acts to cut the abnormal current.

(4) Abnormal pressure or flow detection:

The diplayed value flashes to indicate the abnormal status if the applied pressure or flow exceeds the rated

value by 10%. This error is automatically reset when the supplied value enters the rated range.

(5) ON/OFF point input error warning:

Indicates if the difference between the ON point and OFF point in the window mode exceeds the hysteresis

value + setting resolution (0.01 kPa/1 mmH²O).

Precautions

■ CORRECT USE

■ ENVIRONMENT

• Use within rated pressure.

• Do not use this product where explosive gas, ignitable gas,

or any other harmful gas may be present.

• Do not mix up connecting +, – sign of pressure port. The "+"

sign is for plus pressure, the "–" sign for minus pressure.

• Do not use beyond rated supply voltage or under AC power

supply. Explosion or fire may be caused.

• Do not pull the cable more than 50 N (11.25 lbs).

• Do not mix up DC pole's wiring. Explosion or fire may be

caused.

• Filter the gas with an appropriate air filter so that the applied

gas will be free of moisture or oil.

• This product cannot be used under corrosive gas or

flammable gas.

• When not using linear output and/or the ON/OFF output, cut

the output lead wire and cover the tip with an insulation tube

to prevent wrong connection.

• Do not install beside high voltage line or power line.

• Do not expose to water.

• Do not effect the product by ultrasonic vibration.
