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
