Ventilation and Control
· natural convection
· continuous adjustment of pre-heated fresh air
admixture
· vent connection with restrictor flap
· microprocessor PID-temperature controller
with integrated autodiagnostic system with
fault indicator
· one Pt100 sensor class A in 4-wire-circuit
· integrated digital timer ( 1 min. up to 99 h 59
min) to switch off heating to stand-by mode
· digital LED- display of set and actual
temperature as well as remaining process
time
· resolution of display for set value and actual
value 0, 5 ° C
Overtemperature protection ( double)
· in case of total breakdown of sensor, the
heating is switched off at approx. 10 ° C above
set value
· in case of failure of the switching element, the
heating will be controlled by an additional
relay approx. 10 ° C above the set
temperature
· in case of a faulty sensor ( incorrect
measuring values) or the total breakdown of
the controller the heating is switched off at
approx. 10 ° C above the max. oven
temperature by the mechanical temperature
limiter TB protection class 1
· for very sensitive and/ or valuable load in
terms of being non-reproducable, we
recommend ovens of our E- and P-class
guaranteeing an even higher safety standard
