Temperature monitoring
The control system includes a temperature monitoring function. If the actual
temperature difference with regard to the set value deviates from the set
temperature difference, the centrifuge will stop and an error message will
be issued.
• Activate the temperature monitoring function by clicking.
• Adjust the desired "Delta T" limit value in steps of 1°C or 1°F and
confirm the setting.
If the temperature monitoring function is active, the symbol "
" is displayed
in the temperature field of the "Standard" menu.
In this case, the centrifuge can only be started if the current temperature is
between the preset temperature in the "Standard" menu and the "Delta T"
limit value.
If the temperature leaves this range during the centrifugation run, an error
message will be displayed and the centrifuge will be decelerated to a
complete standstill.
NOTE
The delta T temperature monitoring system remains inactive as long as the
"RAPID_TEMP" program is active (see chapter 6.3.2.5 - "Standard menu",
"Program "RAPID_TEMP"").
Spin-
out from…
If this function is active, the brake will be deactivated when the actual
speed is below the set speed. As a result, the rotor will spin out in a
brakeless manner.
NOTE
A spin-out, in particular with heavy rotors and at high speeds, can take a
lot of time! (Depending on the rotor and load, the speed will be reduced by
approximately 0.5 to 1 rpm per second.)
If the spin-out is active, "+0" is displayed next to the deceleration curve.
• The spin-out can be interrupted by a quick stop or by restarting the
centrifuge.
