Heating zones
Field Description
Set
Specification of the temperature set-point value of the correspond-
ing heating zone. If the operating mode is set to 'Setter', it is not
possible to enter a temperature.
The operating mode of the heater can be selected in the mask
"Heating nozzle setup - tab2".
Tolerance high / Tolerance
low
These fields specify the upper and lower tolerance temperature.
If the current temperature of the heating zone is below Tol. low or
above Tol. high an alarm will be raised. Screw movement is only
possible if temperatures of all heating zones are within their toler-
ances.
Settings
Field Description
Cool prevent time
Specification of the waiting period until release of the screw move-
ment, measured as of the moment when the temperatures of all
heating zones are within the specific tolerance.
Activate standby tempera-
ture
Function is used to hold the temperature of the heating zones
constantly above the standby temperature. If standby is activated,
the standby temperature is adopted as the new set-point value and
no screw movement is possible.
On: Nozzle warming activated. The nozzle is kept at standby
temperature.
Off: The nozzle is not kept warm.
This setting is only effective with the operating mode "PID" of the
nozzle heater.
Material entrance
Field Description
Start temperature cooling
The material entrance cooling will be activated if the temperature
exceeds this value.
Stop temperature cooling
The material entrance cooling will be deactivated if the tempera-
ture falls below this value.
Warning temperature
If the value exceeds the warning temperature, an alarm will be
triggered. The machine is not halted.
Alarm temperature
If the value exceeds the alarm temperature, an alarm will be trig-
