22 HASCO hot runner
The coldest zone then operates with the maximum output level. All other zones control
on the basis of a setpoint value which is calculated from the actual value of the coldest
zone plus an adjustable temperature difference. By default, all the zones are heated
up simultaneously within a single group (Setting 1). Up to 8 further heating groups
can, however, be defined.
As soon as all the zones in a group have attained their setpoint value, the zones in
the group with the next highest setting start to heat up uniformly.
Factory setting: All zones in Group 1 (all values = 1)
Max.
temperature
deviation
All the zones are heated in such a way that they are only permitted to have a specific
temperature difference compared with each other. This value is called the maximum
temperature deviation.
Factory setting: 25°C
Setting limits: 1° … 100°
Ramp gradient The ramp function is executed when a setpoint value is changed. It ensures that the
new setpoint is approached at an adjustable, constant rate.
Setting limits: 0.00 … 99.99 °C / sec
Factory setting: 0 °C (no ramp)
Soft start
The soft start enables gentle heating of the mould. All the zones are heated separately
and gently to a maximum of 100°C, independently of a higher setpoint temperature.
Up to a temperature of 50°C, each zone is heated with a maximum output level of
50%. The output level is then slowly increased to 100% as a function of the actual
value. Once 100°C has been reached, the soft start has been completed and the zone
can heat up at full power.
Factory setting: Soft start is activated for all zones

Setup > Mould test
The mould test checks the sensors and heating units and is particularly useful after initial installation or assembly work,
and also in the event of irregularities during normal operation. The mould test detects: mixed up sensors, heating units
and plugs as well as sensor polarity reversal and short-circuiting. Irrespective of the selection, all zones with detected
and non-detected sensors will be monitored.
First of all, the zones are selected for which the mould test is to be conducted. To start the test, press the start button
with the arrow pointing to the right. The selected zones will now be tested one after the other. The status of the zones
during the test will be shown with the following symbols:
