2. Identifies thermocouple failures heat circuit disconnections and short circuits Corrects polarity errors at thermocouple connections independently by logical turning of the connections Turns off the power supply in case of a malfunction and signals the alarm via a potential free contact Parameters and programs are saved in an EEPROM and are therefore not lost in case of a power supply failure The DPK DPT is designed for easy use this makes installation and tool change simple Advantages for the user The DPK DPT is especially designed for simple and easy operation The multi function keypad has an easy to use layout and because of its dust and water proof key pad it withstands tough environments The simple operator entry level prevents wrong operation All zones and the set and current values for each zone are displayed simultaneously The control parameters are adjustable according to the application The implemented diagnosis function tests the complete system including tools nozzles manifolds and the hot runner system for malfunction and is able to correct possible miswirings independently Circuits connected incorrectly are located before the start of an operation Low installation costs because of combined thermal and power connections The DPK DPT has numerous special functions for optimal system utilization Advantages for the user Power output surveillance is possible during an operation Decreasing
