stopped,
You can press the open button on the control panel to open the door cover of the
centrifuge. The centrifuge can only be started when the door cover is locked!
●
Overspeed
When the operating speed of the centrifuge rotor exceeds the set speed of 600r/min,
the machine will sound an alarm. When the operating speed exceeds the maximum
rated speed of the rotor of 600r/min, the rotor will automatically stop running. The
door can only be opened after the rotor has completely stopped. After troubleshooting,
the machine will restart;
●
Unbalance
If the rotor rotates unevenly during operation, causing the shaft to shake beyond the
specified range, the machine will stop running in a timely manner and issue an alarm
prompt; Generally, the rotor load is unbalanced. After the operation is terminated,
open the door cover, and after troubleshooting, the operation can be restarted.
●
Overtemperature
When the temperature in the centrifugal chamber exceeds the set temperature by
10
℃
, the machine will stop running in a timely manner and issue an alarm prompt.
It can only be restarted after cooling down in the centrifugal chamber.
●
Emergency opening
During the operation of the rotor, if there is a sudden power outage or machine
malfunction that makes it impossible to open the door with a button, manual door
opening can be used (see 2.3.2 for handling).
2.5 Machine placement requirements
2.5.1 The machine should be placed on a level table with sufficient rigidity and away
from vibration and impact equipment, avoiding direct exposure to heat sources and
sunlight.
2.5.2 There should be a space of 20cm to 25cm on all sides of this machine for
ventilation and heat dissipation.
2.5.3 After placement, the level should be adjusted and the four supporting feet at the
bottom of the equipment should be evenly supported on the table.
2.5.4 The applicable range of the instrument's working power supply is AC220V
±
10% 50Hz/60Hz 15A.
This machine must be strictly and reliably grounded, and the
machine power grounding wire must be reliably connected to the
power grid grounding wire! During the operation of the rotor, it is
strictly prohibited to manually power off, otherwise it may cause
damage to the control circuit!
