If threshold
A
value is greater than threshold
B
value, the contact is closed if the
measuring value rises above threshold
A
value or falls below threshold
B
value. The
contact is open if the measuring value is within the two threshold values.
If threshold
A
value is lower than threshold
B
value, the contact is open if the
measuring value rises above threshold
B
value or falls below threshold
A
value.
The contact is closed if the measuring value is within the two threshold values.
6.
Relay activates below threshold B with hysteresis
The contact closes if the measured value falls below threshold
B
. Contact opens
if the measured value rises above the threshold value plus the hysteresis (
B+H
).
