Protection against excess temperature
The centrifuges have 2 different protection systems against excess temperature:
1. Programmable protection against excess temperature (
D
T function)
Depending on the programmed set temperature, an increase in temperature (
D
T) of a minimum of 5 K
can be set. If the display exceeds the value of temperature pre-selection plus
D
T when the rotor is
turning, the excess temperature alarm is activated (LED "overtemp“ is alight, the alarm signal is acti-
vated and the rotor is stopped).
If no value is set for
D
T (display "- -"), the excess temperature alarm is activated when the temperature
display exceeds 51°C.
2. Excess temperature protection sensor
The excess temperature alarm is activated, when the temperature of the sensor located in the rotor
chamber exceeds 70°C.
Lid emergency opening
CAUTION- DANGER!
Opening the lid while the rotor is moving is prohibited!
In the case of a power failure, the electrical unlocking of the lid does not work. To remove the specimen
after the rotor has stopped, there is a manual opening device.
In this case, proceed as follows:
œ
Switch off and disconnect the centrifuge from the power supply.
œ
Ensure that the rotor is at a standstill (view window)!
œ
Unlock and open the front door with a square socket spanner.
œ
Pull down both pull cords on the right, the lid catch is mechanically unlocked.
Accessories
The centrifuge delivered also includes 2 metal rails for rolling the centrifuge down from the palette as well as
an open jawed spanner (17 mm/19 mm) and a socket spanner (10 mm) for assembling and dismantling the
rotor. Two further open jawed spanners (24 mm and 8 mm) are intended for fixing and securing the stand
feet. The square socket spanner is used to open the front door.
Furthermore, 50 ml corrosion protection oil (order number 70009824) for maintaining the metallic rotor and
bucket surfaces and a can of grease (order number 70006692) for lubricating the retaining bolts of the
swing rotor are delivered with the centrifuge.
