Hot Runner Temperature Controls Guard against thermocouple failureProtect control modulesMinimize downtimeImprove processing consistency

Active Thermocouple Protection

Patent Pending

Smart Box Flyer - 20463 ATP

™ ATP™ (Active Thermocouple Protection) is a breakthrough in hot runner control system reliability – available exclusively from Fast Heat.ATP protects hot runner control system components againstCommon Mode Leakage – the short circuit phenomenon which is the leading cause of catastrophic thermocouple failure – and thermocouple failure, in turn, can result in substantial tool downtime and/or control module maintenance/replacement costs.ATP is installed as standard equipment in Fast Heat Pulse®Series controllers and retrofitable into other systems via Fast Heat SmartMold Box™ and SmartMold Connectors™. Protects control modules from thermocouple short circuits Improves thermocouple signal accuracy By preventing shorting of thermocouple circuits, ATP prevents the damage or destruction of hot runner control modules that can result – eliminating associated costs of module replacement and downtime. ATP includes a specialized protection device to help ensure that temperature control modules receive the cleanest, most accurate signal possible from the thermocouple. Excessive signal “noise’ and leakage current is converted into heat preventing transmission of spurious information for more consistent processing.

Features and Benefits

Protects thermocouples from premature failure ATP acts as a “guardian”, constantly monitoring thermocouple circuitry for indications of trouble. When ATP senses excessive Common Mode Leakage, it shuts off power to thermocouples before they fail, while signaling a fault to the hot runner controller diagnostics. Corrective action is prompted (usually tightening of connections) before incurring costs of downtime associated with opening the tool for thermocouple replacement.
