An event is generated
• If the measured values (MV) are increasing, the relay contact is closed when the on-value is exceeded ("Limit value" +
"Hysteresis") and the start delay has elapsed ("Start delay").
• If the measured values are decreasing, the relay contact is reset when the off-value is undershot ("Limit value" -
"Hysteresis") and following the release delay ("Switch off delay").
