NOTE: The hopper throat temperature is to be controlled as follows:
If the actual temperature is lower than the preset hopper throat temperature, the solenoid valve (M161), which is installed in the cooling water circuit under the hopper, is turned OFF to stop cooling water running under the hopper.

[3] Setting of barrel temperature tolerance (Alarm)
Display the [BARREL] or [MON MGT2] screen to set temperature tolerance.

1) Touch the [TEMP] screen selector button.
2) Touch the [TOL] to successively open the setting window to set temperature tolerance of each control zone.
3) Touch [ALARM SELECT] buttons on [MON MGT2] screen to change alarm [ON/OFF].
