Heatup Guided by Reference Channel
NOTE: All activated channels in control mode are included in the heatup
guided by reference channel, including those assigned to an activated
application group.
After every switchon and after standby is exited, the melter returns to
Heatup phase (status display).
Heatup guided by reference channel prevents individual temperature
channels from reaching their setpoint temperature long before the slowest
temperature channel (reservoir/high melt = reference channel). It prevents
hot melt material from charring in hoses / guns and the build-up of material
expansion pressure during heatup. It also helps to save energy.
The actual reservoir temperature serves as the current temperature setpoint
for the guided channels until the reservoir has reached a temperature of
10 °C (18 °F) below its setpoint temperature. Then heatup guided by
reference channel ends automatically. This way all channels reach their
setpoint temperatures more or less at the same time.
Fig. 4-12
When the current temperature setpoint of a guided channel (= current value
of reservoir/high melt) reaches the guided channel’s own setpoint minus
2 °C (3.6 °F), it is excluded from heatup guided by reference channel and
then heats to its own setpoint independently (Refer to Fig. 4-13).
