15.11Relay heating
The function relay heating starts
after switch-on of the hot runner controller
after a zone reset (
after heating switched off
After a setpoint value change the function is no longer effective.
After Standby the function is effective.
Description
In the hot runner controller, a series-connected heating of zones grouped together in
so-called relay groups is carried out. The follow-up group is enabled when the set-
point value band of all zones of a predecessor group is reached.
The relay heating can be combined with the functions
How it works
By the zone parameter [P047]<>0 the zones are grouped into a relay group.
The ascending relay group number defines the order of heating-up.
Setting [P047]=0: Zones heat up directly, independent from function relay heating.
Setting [P047]=1: Zones heat up directly after fulfilled start-up conditions and give re-
lease to relay group 2 after reaching the setpoint value band.
Setting [P047]=2: Zones heat up directly after fulfilled start-up conditions and give re-
lease to relay group 3 after reaching the setpoint value band, etc.
What good is it
This is a gentle heating-up for the plastic located in the hot runner. During heating-
up plastic is kept on a high temperature level only as long as necessary.
