Configuration
side the range "below max value", the action defined for "below max value" is per-
formed. In the case of device start, configuration or plug-in of the sensor, the actions
corresponding to the range in which the current temperature is located are switched.
Example with "Maximum value" of 65 °C, "Minimum value" of 25 °C and hysteresis of 3
°C. The dotted line shows the hysteresis.
Actions during configuration, device start or plugging in the sensor (for given example):
actual temperature
during configuration
actions
70 °C Port A1 Off (above max) + Port A2 On (above min)
45 °C Port A1 On (below max) + Port A2 On (above min)
20 °C Port A1 On (below max) + Port A2 Off (below min)
Action matrix during operation when limit values are exceeded (for given example):
to "above max" to "below max" to "above min" to "below min"
from "above
max" - A1 On A1 On A1 On + A2 Off
from "below max" A1 Off - - A2 Off
from "above min" A1 Off - - A2 Off
from "below min" A1 Off + A2 On A2 On A2 On -
Only the switching operations for which actions have been defined, are triggered. If
no "On" or "Off" action is defined for a port, the port can never reach this state by ex-
ceeding sensor values. Unless it is the initial state.
