External Cooling
Setup and function
If you are planning to connect the device to an external cooling sys-
tem, a cooling register and a control valve are installed. A control
valve opens when necessary to allow cooling liquid to flow through
the cooling register. Temperatures are measured using the Pt100 sen-
sor which is installed by default.
Connection conditions
1
Cooling medium inlet
2 Cooling medium outlet
The connections for an external cooling system are on the top of the
device. The connections are labelled
COOLANT IN
(inlet) and
COOL-
ANT OUT
(outlet). If two or three units with external cooling are
stacked, the lines are connected internally and only the top unit has
connections on the top.
The connection pressure at the inlet of the cooling medium may be
up to 4 bar, the outlet should be depressurised. The external diame-
ter of the hose nozzles is 10 mm.
ATTENTION
The installed valve regulates the temperature by closing and open-
ing the cycle. Hence it can be necessary to install a bypass from
the inlet to the outlet to protect the circulation pump against dam-
age.
