The following information applies to the : CAL3K-AP , CAL3K-A , CAL3K-U, CAL3K-F

The cooler 3K-2 can be controlled from the CAL3K or via the USB port at the rear. The Control from the CAL3K works as follows:

1. The Cooler parameters are entered in the CAL3K
2. When the vessel is inserted in the well these parameters are entered in the Vessel
3. When the vessel is inserted in the cooler then these parameters are loaded in to the cooler
4. The cooler checks them, and if correct, executes them

The cooler indicates this on its display: COOLING FROM VESSEL

Another way to change the cooling parameters is to connect the cooler to a PC via the USB interface and change the parameters.

The cooler requires that the room (ambient) temperature is about 8 degree LOWER than the Cooler ‘ready’ temperature to obtain a 7 minute cooling cycle. Otherwise the cooling time gets longer. This leads to a situation where the CAL3K is faster than the cooling. Of course, using multiple cooler helps.

The cooler has two operating modes:

Fixed cooling target

The vessel is cooled to the ‘READY TEMPERATURE’ and then the fan stops. This insures a fixed vessel starting temperature.

Variable cooling target

The vessel is cooled to a temperature which is the sum of the Ambient and a constant addition. This insures constant cooling times

CAL3K COOLER PARAMETERS

COOLER SYSTEM DEFINITION: ENABLE

If set the cooling parameters from the vessel are used

If reset the cooling parameters from the cooler are used

COOLER SYSTEM DEFINITION: AMBIENT ADDITION

If set the cooler target temperature = Ambient + Addition (limit =Maximum Ready Temp)

If reset the cooler target temperature = Ready temperature
