4.2.4 Shaking Control
Quin drive shaking system ensures smooth and reliable orbital shaking movement
with a speed range between 30-300rpm. The orbital diameter is adjustable from 1mm
to 50mm continuously. The loading weights must be low the maximum rated, other-
wise, it will prevent the shaking tray from smooth movement, and eventually increase
the wear out the bearings and joints.
4.2.5 Temperature Control
The heaters are behind the back wall. The temperature is controlled with a PT100
temperature sensor. The heat generated is distributed via 2 cross fan evenly across
the inner working chamber. Over temperature protection is in place. The melting fuse
switch off the heating at 85°C. In addition, the capillary thermostat protects the
temperature overheating with adjustable range up to 120°C.
4.2.6 Control Electronics
The microprocessor controller is equipped in the front door. It is designed to service
the precise control requirements of the working chamber environment, providing op-
timum programmable conditions for culture growth. The microcomputer is “us-
er-friendly” with 5.6’’ large touch screen to permit efficient operator entry and settings
of data.
Each stack of unit is operated independently its own controller.
4.2.7 Front Door & Shaking Tray Operation
The shaking tray of the equipment is locked in place while the door is closed. When
the door is fully open, the locking hocks release the shaking tray and in the same time
the releasing switch lifts the shaking tray out of the locking cones on the base tray.
Then the shaking tray can be pulled out over the tray support rails, and the sliding
bearings on the door. Once the shaking tray is pulled out to the end, the shaking tray
can be removed freely.
The shaking movement of the tray is interrupted as soon as the door is opened by
more than 20°of angle. The shaking tray can only be ejected once the shaking tray
stops completely. In the same time, the heater stops working at the same time when
door is opened.
Shaking movement and heating controlling resumes once the door is closed.
DANGER!
MAKE SURE THE SHAKING TRAY IS COMPLETELY
STOPPED BEFORE OPENING THE FRONT DOOR!
Failure of doing so will cause severe damage to the door
locking system, hence door ajar alarm may be activated!
