NOTE
Danger of roller damage: Using a tempering fluid without corrosion protection
results in corrosion inside the rollers.
Observe the coolant specification (see chapter 6 Technical data).
NOTE
Danger of damaging the rollers:
5. Inlet flow temperature of the rollers
min.
10 °C (50 °F)
to
max. 55 °C
(130 °F)
.
6. Maximum temperature change of supply temperature in temperature
control process:
30 °C/h (54 °F/h)
!
›
Adjust the settings at the temperature control unit accordingly.
›
If necessary, program the maximum temperature limits to be set at the
temperature control unit (see operating instructions of the temperature
control unit).
›
Fill the temperature control unit with water and corrosion protection agent.
›
At the temperature control unit, set a bath temperature of approx. 20 °C.
›
Switch on the pump of the temperature control unit and check proper coolant
flow after some minutes.
›
Switch off the pump.
9.5.2. WITH PRESSURELESS COOLING
Link back to chapter 3 Installation information in advance
NOTE
Danger of destruction of device components
›
Check coolant filling level during operation.
›
If the filling level is steadily increasing in the green area or latest if it is too
high as indicated by the red area, there is a risk that coolant will overflow
within the machine.
›
Check coolant flow in the return flow for obstacles (kinks, cloggings, steady
gradient), reduce inlet flow if necessary.
