• as of software 3.1 • Version: 01.03.2017 • Technical changes and errors excepted.
5.7.1. Coolant temperature monitoring
A threshold value can be set for the temperature of the coolant, which is based on the
current dewpoint temperature. The switching output of the coolant temperature mon-
itoring system can provide a warning prior to any build-up of condensation in the sys-
tem, and/or activate appropriate countermeasures.
Minimum coolant temperature threshold value
Threshold value = dewpoint tempe offset
Switching output
The output switching delay can be set using objects or directly as a parameter.
The offset set last shall be maintained
• never
• after restoration of power
• after restoration of power and program-
ming (do not use during initial setup)
Offset in °C
(only if the offset is not retained, or
retained after restoration of power)
0...20; 3
Step size for offset change using communi-
cation object
0.1°C • 0.2°C • 0.3°C • 0.4°C • 0.5°C • 1°C •
2°C • 3°C • 4°C • 5°C
Hysteresis of the threshold value in %
0 ... 50; 20
Threshold value sends

• periodically
• on change
• on change and periodically
From change of
(is only sent if "on change" is selected)
0.1°C • 0.2°C • 0.5°C • 1.0°C • 2.0°C • 5.0°C
Send cycle
(is only sent if "periodically" is selected)
5 s • 10 s • 30 s • 1 min • … • 2 h
When the following conditions apply, the
output is
(LV = Threshold value)
• LV above = 1 |LV - hysteresis below = 0
• LV above = 0 |LV - hysteresis below = 1
• LV below = 1 |LV + hysteresis above = 0
• LV below = 0 |LV + hysteresis above = 1
Delays can be set via objects
(in seconds)
No • Yes
Switching delay from 0 to 1
(when delay is not set using objects)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
Switching delay from 1 to 0
(when delay is not set using objects)
None • 1 s • 2 s • 5 s • 10 s • … • 2 h
