HASCO hot runner 58
The upper and lower alarm threshold value can be activated and set separately.
Alarm
limit values are always relative to the active temperature setpoint.
Activation of each
alarm is indicated by an orange colouring of the respective button (Exemple see pre-
vious page, lower and higher alarm are active).
When pressing one of the keys „Upper limit value“ or „Lower limit value“, the known
num-pad opens, where you can enter the desired new limit value. The actual value is
displayed in the field and will be updated after modification.
With the key „Signal inverted“, the switching behavior of the alarm relay for the external
alarm output (chap. 4.4, see page 12), the actual state is shown by an orange colou-
ring of the button.
If the output is inverted, the alarm relay is then closed if no alarm is
present. This type of signal is needed for some injection presses for release of the pro-
cess.
All temperature alarms of all zones are operating the common alarm A1, which is wired
to a floating contact on the alarm connector on the back of the device, see chapter
4.4 .
Is the temperature alarm configurated as a range alarm or low temperature alarm, the
common alarm A1 can be used for production release of an injection press. Depending
on the type of switching contact of the press, the alarm might need to be inverted, see
examples previously described.
After having finished the limit value entry, quit the menu with the red cross and get
back to the „zone configuration menu“.
