Cooling Unit
At watercooled machines, the
fl
owrate of the coolant is measured in the return
fl
ow. The
fl
owmeter output is a
digital signal where it’s frequency is proportional to the
fl
owrate. The higher the
fl
owrate, the higher the frequency.
If the
fl
owrate is below 0.3 liter per minute, the machines will stop and dislays
E05
(cooling system error).
Schematic
The actual
fl
owrate can be monitored via the front panel in menu Extras, Diagnosis, Flowrate Cool. System.
At gas cooled machines instead of the
fl
owmeter, there is a small cable bridge between pin 1 and 4 at connector
X9. This cable bridge is deactivating the monitoring of the
fl
owmeter.
