Function

Description

Auto-teaching

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

(continued)

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%)

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.

Key-protect

This function restricts switch operation to prevent the set value from being easily changed.

Speed control

Select from three values of display speed for the measured pressure values. Set value: 0.1 s, 0.5 s, 1.0 s

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
