3.1.4 Temperature screen

Operating sequences
Press this key to enter the Temperature screen 1. See Fig 3-15,
Temperature screen 1.
This screen is used for SIJECT 15
barrel and 1 channel for oil temperature. Temperature values for each
channel can be set on this screen. For the nozzle, either open loop or
close loop can be selected.
If the nozzle is under open loop control, the indicator at "Open loop" will
backlight. Users can set a percentage value in Nozzle block so as to
make sure the percentage of heating on/off in a time unit. For example, if
time unit is 20s, and nozzle is set as 30%. Then heating time is 20 x 30%
= 6s and heating off time is 14s.
If the nozzle is under close loop control, the upper and lower tolerance
can be set here which is valid for all temperature zone. When the
temperature is within specification, channel heating will maintain the
temperature within this range. The indicator ⑧ (see table 3-1) will stop
flashing, which means the screw can work at this situation.
If Hold function is selected, the block of Holding will backlight. Holding
temperature can be set for each temperature channel.
The unit of temperature will be °C.
Note:
Here, the thermocouple should only be type K.
Nozzle open loop control: no thermocouple is mounted on nozzle. Nozzle
heating can be executed via heater on/off.
For the selection of open loop / close loop, please refer to section "3.1.10
Service screen --- temperature setting".
