3.2 Standard equipment of HCP units
• Electronic fuzzy-supported PID process controller with plus-package control and permanent power
proportioning and a time-saving autodiagnostic system for rapid fault finding (see section 22)
• Recessing push/turn control for simple operation of oven
• Language selection (English, French, Spanish, Italian, German)
• Alphanumerical text display
• Large-area all-round heating with additional heat conduction jacket
• Capacitive humidity sensor
• Active humidity control (fresh air via sterile filter) avoids condensation and ensures rapid
achievement of set humidity as well as short recovery times
• Uniform atmosphere and temperature distribution through encapsulated and turbulence-free
ventilation system
• Control of oven and documentation of actual values on MEMoryCard XL
• Programme sequence control for up to 40 ramp segments
• 7 different ramp exit commands for advanced temperature applications
• STERIcard for fully automatic sterilisation control during hot air sterilisation of complete cabinet
including sensors and fan disc
• Integral weekly programmer with group function (e.g. all workdays)
• Two separate PT100 temperature sensors Class A in 4-wire circuit for control and monitoring
• Digital monitor controller for overtemperature, undertemperature, and as automatically setpoint
following monitor (ASF)
• Mechanical temperature limiter (TB Class 1)
• Monitor relay to switch off heating in case of fault
• Visual alarm indication
• Audible signal on over-/undertemperature, over-/under-humidity and open door
• Internal documentation memory 1024kB as ring memory for all temperature and humidity values,
errors and settings with real-time and date. Documentation approx. 3 months at 1 minute storage
interval
•
Calibration possible without separate PC: 3-point calibration for temperature on the controller and
2-point calibration for humidity at 20% rH and 90% rH
• Parallel printer interface (PCL3-compatible) for printing documentation data
• Serial RS-232C interface for computer-supported temperature programmes and for reading the
internal report memory
• MEMMERT software “Celsius 2007“ for control and documentation of temperature and relative
humidity via a PC
• A pre-formatted blank MEMoryCard XL with 32 kB storage capacity, reprogrammable for up to 40
ramp segments and additionally 270 hours report memory at 1 minute intervals
