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.
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 it is open, the pressure indicated on the
display corresponds with the actual ambient pressure. When the DAC
UNIVERSAL is turned on, but it is not being used, the pressure indicated
on the display is always approx. 1 bar, when it is at sea level. If air
pressure is high, the pressure will be approx. 1.03 bar and if pressure is
low approx. 0.98 bar.
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 is 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, a error
message is shown on the display.

Transport
CAUTION
The bottom plate of the DAC UNIVERSAL can be hot.
CAUTION
When handling the DAC UNIVERSAL it is important to grab the
autoclave underneath the machine with two hands.
It is important to get a firm hold of the machine, as it is quite heavy. It is
not recommended to lift the DAC UNIVERSAL and carry it over a long
distance.
Carrying the DAC UNIVERSAL over a short distance can cause
problems for persons who are not used to lift objects as heavy as the
DAC UNIVERSAL.
The DAC UNIVERSAL weighs approximate 23 kilograms/51 pounds.
Separately, the lid (inclusive 6 adapters) weighs approximate 1.7
kilograms/3.75 pounds.
