Safety devices
Safety valve The safety valve was developed according to the EN 4126-1 standard
and calibrated according to the EN 764-7 standard. The safety valve in
the DAC Universal opens when the relative pressure in the chamber
exceeds 3.5 bar.
Chamber pressure- /Temperature test To protect the chamber, the relative pressure and the temperature of the
DAC Universal are continuously monitored. If the pressure or the
temperature exceeds the design limits of the DAC Universal, an
associated error message appears on the display.
Absolute pressure sensor The DAC Universal has an absolute pressure sensor and adjusts
automatically to changed pressure levels. The absolute pressure is
indicated on the display. When the lid is open, the pressure indicated on
the display corresponds with the actual ambient pressure.
Watchdog relay When the microprocessor in the DAC Universal does not send a signal to
the two watchdog relays, they switch off the power supply to the pumps,
valves, motor, and steam generator.
Safety ring When the safety ring is activated, the motor stops the lid immediately. The
safety ring has 9 contacts. The safety ring is automatically tested before
the start of every cycle. The circuit is always tested when the power
supply is switched on.
Electrical safety Before the DAC Universal leaves the factory, an electrical safety test is
conducted according to EN61010-1.
Fuses are attached to the main circuit board to protect against electrical
overload.
Software safety The software has a number of display messages (error codes) that
interrupt the process if pressure, temperature, etc. do not comply with the
target values during the cycle.
Sterilization/disinfection control system The sterilization/disinfection control system regulates the pressure and
corresponding temperature simultaneously. If temperature or pressure
are above or below the thresholds for sterilization/disinfection, an error
message is shown on the display.
