Ventilation and Control   

• forced air circulation by quiet air turbine adjustable in 10% steps via process controller, for each segment individually   
• adjustment of pre-heated fresh air admixture by air flap through process controller in 10% steps for each segment individually   
• vent connection with restrictor flap   
• adaptive, fuzzy-supported, multifunctional, digital microprocessor PID-controller   
• autodiagnostic system with fault indication   
• 2 Pt100 sensors Class A in 4-wire-circuit, mutually monitoring and taking over the performance at the same temperature value   
• digital 7-day-programme-timer with real time clock, precise minute setting, for one set value or start of ramp operation   
• integrated timer for tempering profiles of up to 40 ramps, each segment adjustable from 1 min. up to 999 hours   
• multifunctional programming via menu on 8-digit alphanumeric digital display (language to be chosen via set-up):   
• tempering profiles of up to 40 ramps   
• time- and set-point dependent operation   
• air flap adjustable in 10% steps   
• speed of air turbine in 10% steps   
• digital display (LED) of all set parameters, such as temperature, weekdays, time, fan speed, air flap position, programme status and set-up values   
• resolution of display for set value 0,1 °C below 99,9 °C, 0,5 °C above 100 °C; for actual value 0,1 °C   
• long-term logging (ring store) of all relevant data, GLP-conforming as data logger - 1024 kB   
• programme stored on power failure   
• parallel printer interface (incl. real-time clock with date function) for printing logging files, suitable all PCL3-compatible ink-jet printers (USB available via converter, see accessories)   
• serial interface RS 232 including MEMMERT Software "Celsius" for programming and documentation   
• chip card control incl. one MEMoryCard XL with 32 kB (up to 40 ramps)   
• incl. works calibration certificate for +160 °C   

Multiple Overtemperature Protection   

• with audible and visual alarm   
• digitally adjustable, electronic microprocessor overtemperature controller TWW protection class 3.1 - maximum value for overtemperature - minimum value for undertemperature   
• additional integral over- and undertemperature monitor "ASF" (Auto-Safety-Function) automatically following the setpoint value at a preset tolerance range; audible alarm is activated in case of over- or undertemperature, heating is switched off in case of overtemperature   
• resolution of display and setting accuracy: 0,5 °C below 99,9 °C, 1 °C above 100 °C   
• mechanical temperature limiter TB protection class 1 switching the heating off at approx. 10 °C above max. oven temperature
