For normal open:

(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.

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

Functions Table - continued from previous page

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.

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 mmH

O).
