Other Information

The universal tank control LE-200 has a function allowing the agitator to be
switched on manually in cooling mode. This can be done is different ways.
Regardless of the chosen option the corresponding LED always indicates when the
agitator is operating.
The function is set at configuration level using parameter [P22].
Parameter [P22] is set to 0:
"Intermediate stirring" is not possible.
Parameter [P22] is set to 1 (standard) :
"Intermediate stirring SHORT or LONG" can be switched on via the regulator's foil
keyboard. In this case:
• Intermediate stirring SHORT = Press agitator button for approx. 1 sec.
until "Sho" appears in the display. Release the button immediately
- otherwise "Intermediate stirring LONG" will be activated.
• Intermediate stirring LONG = Press agitator button for approx. 3 secs.
until "Lon" appears in the display. The duration of the stirring run SHORT or
LONG is defined in 'General cooling parameters' via parameters [C23]
and [C24].
Parameter [P22] is set to 2:
Function: Continuous stirring ON / OFF
By pressing the button the agitator is switched on and can be switched off by
pressing the OFF-button.
In the OFF-mode the agitator can be switched on by button "agitator" and
switched off by button "OFF".
if Parameter [C25] = '0'
The agitator continues to run until the OFF-button is pressed. There is NO
automatic switching off.
if parameter [C25] > '1 .. 999'
The agitator stops automatically after the set time.
A rotating bar appears in the display during continuous stirring.
Sensor correction means:
A correction is applied to the value measured by the sensor. This is then cumulatively
effective over the whole measurement range.
An adjustment to the sensor correction is then necessary only:
• in conjunction with first installation,
• if the sensor cable length is altered,
• when replacing a faulty sensor.
In order to adjust the sensor correction, a reference thermometer is needed.
Proceed as follows:
• Switch off power supply
• Install / change sensor
• Use the reference thermometer to establish the milk temperature.
• Switch on control unit and set [c90] to the measured number of degrees.
The control unit calculates the difference between the reference thermometer
reading and temperature sensor 1 and automatically sets this in parameter [c91].
• Parameter [c91] can be displayed and adjusted at any time.
• Hold down the up and down arrow buttons simultaneously:
The settings are stored.
