HOT RUNNER TEMPERATURE CONTROL
HR is a multi-channel microprocessor temperature controller designed to control heating of nozzles and channels of hot runner system matrixes. It is specially developed for obtaining maximum flexibility and reliability of the system, as well as for simplicity and convenience when used by the user. HR is also open to be connected to another control. As a whole, the device is light, convenient and compact.
Flexibility
- 3 available models - HR8, HR16 and HR24 respectively with 8, 16 and 24 zones;
- possibility of paralel work of several HR units in order to control greater number of zones;
- zone control according to the PID Control Law for regulation with adjustable parameters;
- possibility for putting of output modules of different power in each model;
- option of automatic or manual control of output of each zone;
- possibility for manual slave the output of one zone to another zone;
- individual zone settings to failure limits;
- Take out the signals to HD connectors with or without cables as per user’s desire
Reliability
- possibility for soft start of heating to dry out the moisture that has collected in the cold heating elements;
- possibility for simultaneous BOOST of temperatures of all zones after warm up starts;
- possibility for auto slaving of output of one zone to another on temperature sensor failure;
- constant diagnostics for problems, and alarms for: wrong parameters (in the memory), temperature sensor failure, non heating or overheating of a zone, exceeding of maximum temperature, temperature out of the set alarm and failure limits, overheating of output modules of the device, etc.;
- storing of parameters in nonvolatile FLASH memory;
- protection against change of key parameters by a password on level ‘adjust’;
- turning on and off of power elements when passing through zero of supply voltage for low EMI level;
- protection against overheating of output modules;
- protection against output failure (short circuit in heaters) by fast fuses for each zone;
- Protection against overheating of zones (at short circuit in control element), disconnecting power supply by built-in contactor;
Easy-to-use
- digital and navigation keyboard, and 4 x 20 characters LCD for setting parameters;
- bright 3-digit 7-segment indication of each zone for remote monitoring of the following parameters: setpoint, current temperature, percent of output power, difference between set and current temperature, etc.;
- LEDs for each channel, indicating switched on heater or error;
- common LED indicating that temperature of all zones is within set limits;
- simple menus on operator’s level;
- independent keys for simultaneous start, stop, temperature BOOST or STANDBY in all zones;
- possibility for individual or group setting of parameters;
- possibility for storing of 10 settings of all parameters for quick presetting when changing the matrixes;
- built-in settings of PID parameters for two types of zones – ‘mainfold’ and ‘nozzle’.
- easy access to fuses of heaters from front panel;
