Firebox Temperature Controller
Overview
The Firebox hot runner temperature controller is specifically designed to interface with the Polyshot Heated Sprue Bushing, Multitip System, and the Bank System, ensuring seamless integration with your hot runner system. It is engineered to withstand the rigorous environment of the injection molding room floor. This hot runner temperature controller is a closed-loop unit with provisions for manual or “Open Loop” temperature control.
The 3601 Firebox hot runner controller features an Auto-Tuning PID function, which precisely matches the controller’s electronic algorithms to the hot runner system it is connected to. This is accomplished by engaging the Auto-Tune function through the operator interface, which initiates an electronic tuning cycle between the hot runner temperature controller and the hot runner system it’s controlling.
Upon completion of this cycle, the Firebox hot runner controller rewrites its PID algorithms to precisely match the runnerless molding system it is controlling. When coupled with the controller’s burst fire relay system, the hot runner temperature control of processing temperature is excellent.

Features
- Upper Display: LED display indicating hot runner temperature as measured by Type J Thermocouple.
- Lower Display: LED display indicating set point during Auto mode and the percent power during Manual mode for hot runner controllers.
- Load: LED indicates when the Zone is energized.
- ALM: LED indicates when the alarm is active.
- MAN: LED lit when the hot runner temperature controller is in Manual mode.
- Mode Key: Steps the hot runner controller through Alarm Low, Alarm High, and Auto-tuning options.
- Up Key: Increases the set point for hot runner temperature controllers, ensuring precise control during the injection molding process. Also used in alarm setting and auto-tuning procedures in the hot runner system.
- Down Key: Decreases the set point for hot runner temperature controllers. Also used in alarm setting and auto-tuning procedures.
- Auto/Manual Key: Clears the alarm when pressed once. Toggles between Auto and Manual mode for hot runner temperature controllers.
- Circuit Breaker: To activate the Firebox hot runner controller, the rocker switch must be pushed to the “on” position. This switch should be “off” whenever the hot runner temperature controller unit is being plugged in or unplugged from a 208-240 volt single-phase outlet.
- Thermocouple Failure Protection: If the hot runner temperature process was stable when the thermocouple failed, the hot runner temperature controller will transfer from auto to Manual mode. The hot runner system will automatically continue at the power level experienced in the two minutes prior to the power failure, provided that the level was less than 75%, and a power change of less than 5% occurred. This will allow the hot runner system to continue functioning until a thermocouple repair can be made. The reliability of our hot runner temperature controllers ensures that the percentage of power is accurately displayed in the lower display. If the hot runner temperature process is not stable or the power level is greater than 75%, the output is disabled.
- Alarms: User-defined hot runner temperature limits that are the extremes on either side of the set point at which the hot runner systems can operate.
- Alarm Low: Represents the low hot runner temperature alarm. The alarm sounds when the hot runner temperature strays too far below the set point.
- Alarm High: This represents the high hot runner temperature alarm. The alarm sounds when the hot runner temperature strays too far above the set point.
- Auto-Tune: Provides automatic tuning of the PID parameters to fit the characteristics of your particular hot runner thermal system. Successful completion of the auto-tune procedure requires the hot runner temperature to cross the set point four times within eighty minutes after auto-tune has started. Typical auto-tune procedures for hot runner temperature controllers last five to ten minutes. During auto-tune, the lower display alternately displays the set point hot runner temperature. Any change in set point while in auto-tune reinitiates the auto-tune procedure. Auto-tuning should be repeated after making any changes in the molding process.
- Temperature Units: The Firebox is capable of measuring temperature in both Celsius and Fahrenheit. The default setting is Fahrenheit. To change the setting to Celsius, contact Polyshot for further information.
