The manually set monitor temperature and the electronic overtemperature protection are monitored on PERFECT incubators by an adjustable temperature monitor (TWW) Protection Class 3.1 to DIN 12 880, or by an adjustable temperature limiter (TWB) Protection Class 2 to DIN 12 880. The choice of temperature monitor is selected in SETUP (see the menu item Tolerance margin ASF in Section „Basic oven settings”) 13.2.3 Adjustable temperature monitor (TWW) Protection Class 3.
13.2.5 Automatic temperature monitor (ASF) AUTO A monitoring device which automatically follows the selected temperature setpoint. The tolerance margin of the ASF is set in SETUP (see the menu item Tolerance margin ASF in the Section „Basic oven settings SETUP“). Automatic temperature monitor Using the push/turn control select the AUTO OFF symbol. °C Hold down the SET key and select off using (ASF OFF) the push/turn control.
Going outside tolerance margin = ASF alarm Going outside the selected tolerance margin of the setpoint (in the example 150°C +/-10°C), for example through opening the oven door during operation, triggers the alarm. -symbol. Triggering the ASF alarm is indicated by flashing AUTO and If the sounder is switched on in SETUP, the ASF alarm is additionally signalled by an interrupted tone. By pressing the SET key the sounder can be switched off temporarily until the next occurrence of an alarm event.
Setpoint changed = ASF de-activated automatically If the temperature setpoint is altered, the automatic temperature monitor is automatically de-activated temporarily (see in the example the setpoint is changed from 150°C to 75°C) until the tolerance margin of the new temperature setpoint is reached (see in the example below: the ASF is re-activated at 75°C +/10°C).
14 Calibration User-calibration of oven and controller, with three calibration temperatures selected by the user. CAL1 temperature calibration at low temperature CAL2 temperature calibration at medium temperature CAL3 temperature calibration at high temperature Either a positive or a negative calibration correction can be applied to each selected calibration point. General calibration instructions: 1. 2. 3. 4. 5.
Note: If all calibration corrections are set to 0.0°C the factory calibration is restored. Calibration point 1 Calibration temperature Range down to 10°C below CAL2 h Calibration point 2 Calibration correction Range –4.9°C to +4.9°C ˚C Calibration temperature Range 10°C above CAL1 to 10°C below CAL3 h Calibration point 3 Calibration correction Range –4.9°C to +4.
15 Communication interface for the PC 15.1 Communication interface RS232C The oven is provided as standard with a serial communication interface RS232C according to DIN 12 900-1. Using this interface it is possible to control the oven from the PC and to produce reports. This is done using the “Celsius“ software. For this purpose the oven has to be assigned a unique device address in sub-menu SETUP, option ADDRESS; This is the address through which the PC communicates with the oven.
15.2 Bus interface RS485 When so ordered, the oven can be equipped at the factory with an RS485 interface instead of the RS232C interface. This permits networking of several ovens (up to 16) with a single PC using a common 2-wire circuit. The system is operated using the “Celsius” software. A unique device address has to be assigned to the oven in sub-menu SETUP, option ADDRESS. This is the address through which the PC communicates with the oven. The default setting is ADDRess 0.
16 Heating power distribution BALANCE On ovens series INP 500-800 and UNP/UFP 400-800 it is possible in SETUP to correct the heating power distribution BALANCE between the top and bottom heater groups to suit the individual application. The adjustment range is –50% to +50%. The setting 0% restores the factory-set heating power distribution.
17 Report memory The controller continuously records all relevant measurements, settings and error messages at 1-minute intervals. The internal report memory is arranged as a ring memory, i.e. the new data always overwrite the oldest report data. The report function can not be switched off but remains active at all times. The data are stored in the controller, protected against any manipulation. The controller memory can be read to produce documentation. Every data set is stored with a unique date stamp.
18 Memory card: MEMoryCard XL A temperature programme with up to 40 ramps can be programmed on the MEMoryCard XL. Programming can take place directly on the controller or through the PC program “Celsius”. For improved clarity it is recommended that extensive programmes are prepared graphically on the PC. Where a MEMoryCard XL is programmed, it can be read only on the same oven type for which it has been programmed.
Note: The programme remains stored on the Memory Card XL after the card has been removed from the unit. It can however be overwritten at any time by the PC using “Celsius”. Details on programming the MEMoryCard XL with PC and „Celsius“ can be found in the „Celsius“ Operating Manual and in the Online Help. 18.4 Documentation on memory card MEMoryCard XL The actual temperatures can be documented continuously on the memory card while the programme is running from the chip card.
19 Sterilisation chip card (for INP incubators only) Sterilisation Parameter: 160 °C / 4:00 h Unit-ID: ________________________ Sterilisation Process Control Card The STERICard starts an automatic and preset sterilisation process. The automatic sterilisation process starts as soon as the STERICard is inserted into the oven and started by the user.
20 User-ID-Card (available as optional extra) Name: _____________________ ID: _____________________ access authority card The User-ID-Card stores the serial number of the oven and a unique user number in encrypted format. The User-ID-Card therefore functions only in the oven with the corresponding serial number. Each log-on via the User-ID-Card is documented in the internal flash memory. If the User-ID-Card is inserted, the SETUP menu includes the additional item ID-LOCK.
21 Sterilisers 21.1 Purpose definition for MEMMERT hot air sterilisers The oven SFP is intended for the sterilisation of medical materials by dry heat using hot air at atmospheric pressure. 21.2 Notes in accordance with Medical Products Guidelines For sterilisers in the context of the Law on Medical Products (MPG), the „Celsius“ software may only be used for logging purposes, but not for the remote control (remote operation) of devices. The product lifetime specified by the manufacturer is 8 years. 21.
The following table gives typical values for the holding time to be set, with different amounts of load, for sterilisers with and without fan. Please note that these values can be employed only with correct and loose distribution of the load. Notes on the correct loading of the steriliser can be found in these Operating Instructions and also on the label affixed to the steriliser.
Programming example steriliser The steriliser (SFP600) has to sterilise at a temperature of 180°C and a medium quantity of load for one hour and 30 minutes.
