Auto-swap

A thermoregulating system must constantly read the temperature of the controlled object so as to determine the amount of power that needs to be sent to the heaters.

When a thermocouple fails, a standard controller, not being able to determine the temperature of the controlled object, must completely interrupt power output, and the controlled objects cool down.
Traditional module
 Extended reliability
In standard thermoregulation each module controls one nozzle. Using Sicem extended reliability controllers, each module controls two heaters.
If the thermocouple of one nozzle breaks, the nozzle stops working and cools down. If the second thermocouple breaks, also the second nozzle stops working and production stops entirely. If one nozzle's thermocouple breaks, the controller keeps regulating using the second nozzle thermocouple. If also the second thermocouple breaks the module automatically switches to manual mode and supplies an amount of power calculated using previously calculated statistical data. Sicem's system is safer and can save up to 50% in controllers. Not bad! For once safety means also convenience...
  • Cluster MC 3800 controllers constantly read temperaturesusing two themocouples and will automatically exclude from the circuit the ones that stop working properly.
  • They can alos be programmed so that in case of both thermocouples failure, the module automatically commutes to manual operation, supplying an amount of power statistically calculated based on previous operation.
Handling two thermocouples with a single controller is an exclusive of Cluster MC 3800 modules and an example of cutting edge technology at Sicem; but all other modules can be programmed to fall back to manual operation in case of thermocouples problems
