Other informations
8.1
Detection of mode “cooling” - parameter [h1]
This parameter determines how the tank monitor can detect the beginning and end
of the cooling mode.
Setting parameter [h1] = 0
Permanent signal from the cooling tank control (cooling active).
Select setting, when tank control detects an active cooling mode via permanent sig-
nal.
Setting parameter [h1] = 1
Activated by trigger signal “cooling activated”, end by starting the cleaning cycle.
In this setting the mode “cooling” will be kept until mode “cleaning” is detected. Tank
monitor cannot detect the switching off of the cooling.
Setting parameter [h1] = 2
Same as setting 1, however, with end-detection.
This setting is an additional safety option.
The tank monitor finds the target value based on the switch-on points and shut-off
points of the cooling. If the temperature exceeds the found out target value without
an active cooling, this will be interpreted as switched off cooling - change into mode
“OFF”.
NOTE: For an effective use of this function the signal should come from the “com-
pressor”, and the target value should not be changed during a cooling cycle.
Thus a deactivation of the cooling mode can be detected.
8.2 Safety function:
“First milk in the tank” [h2]
A cooling mode can only be detected if the cooling of the tanks has actually been
started.
If warm milk is fed into the tank and an active cooling mode has not been detected,
there must be an alarm.
The additional safety funct
ion “first milk comes into the tank” can be set and param-
eterized. Independent on parameter [h1] the cooling mode detection can also be
detected with “first milk comes into the tank” [h2].
(Makes no sense in case of robot operation).
