FUNCTIONS
Description
Switches between mmH2O and kPa, excluding the E8Y- -F
Two independent outputs can be set.
(1) Output mode (mode is automatically determined from the ON and OFF point set values.)
Hysteresis mode:
If ON point point set value > OFF point set value
For normal open:
Window mode:
If ON point set value < OFF point set value
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).
Hysteresis:
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.
Output
ON
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

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%
