1.1 GENERAL DESCRIPTION
•APPLICATION: Impulse heat-seal technology is used to seal, rapidly and with great accuracy, polyethylen films,
polyprophilene films, single-component plastic films, multilayer plastic films in general, that must reach their melting
temperature and a cool down immediately to avoid deformations.
•OPERATING PRINCIPLES: To execute impulse sealing, use a sealing bar with a sealing band o wire electrically
insulated from earth, supplied by an equipment specific for impulse sealing, i.e. an impulse thermoregulator. This
equipment must supply the power required to heat the band at the desired sealing temperature in an extremely short time
and maintain the desired temperature with high precision during all the sealing operations; No additional probe are
required, the equipment simpy reads the feedback signals from the bands and controls the heating current with a closed-
loop circuit. The termoregulator first receives a pre-heat signal from the outside so that the sealing bar can reach a
required pre-heat temperature not far from sealing temperature before starting works. The thermoregulator further
receive a sealing signal from the outside so that the sealing bars can reach the correct sealing temperature when brought
together.
•MAIN FEATURES: The thermoregulator UPSCR_M_V4 is manufactured in 3 versions, differrent only in current,
30/60/90 Ampere; it is interchangeable with all thermoregulators of our company, manufactured before.
With the last software release, the thermoregulator is very easy to use: it works as a thermometer, whose probe is the
band itself: at start up, an analog balancing is done, an automatic burn-in is possible to do, the machine is ready to
work.
At change of band, an automatic balancing is done, an automatic burn-in is possible to do, the machine is ready to
work.
The thermoregulator do many controls and locate faults referring to the display; it is also possible analise bands by
display.
It’s possible enable a special function to control power delivered to bands and increase so the safety.
It’s possible enable a special function to exchange data with a supervisor by serial interface and set temperatures from
distance.
•DIAGNOSTICS: The temperature controller comes with an efficient diagnostics system capable of identifying faults
which have occured during the production process, indicating the cause and suggesting the remedies required to restore
normal operating conditions.
