External Laser Module
The External Laser Module has been designed for flexible placement. It can be located either
to the left or right of the scanner, or placed directly below the scanner in an under-bench
position. The maximum distance between the external laser and the scanner is 2 meters, as
determined by the optical fiber that connects the two instruments. Once the External Laser
has been installed and aligned it is not recommended to move it around to prevent any possible
optical misalignment.
The External Laser Module has a weight of approximately 30 kg and to avoid personal
injury the same precautions listed for the scanner should be taken when lifting the module.
The external laser should only be placed on a surface capable of easily supporting its
weight and located in a well ventilated area with 20 cm of clearance on the left hand side,
top and rear of the unit. The unit has the following dimensions: 31 cm wide, 61 cm deep,
41 cm high.
Warning: Do not position the External Laser Module inside a cupboard or similar enclosure
with poor airflow, as insufficient ventilation may cause permanent damage to the unit and
present a hazard.
Screen Eraser
The Screen Eraser has no minimum clearance requirement and may even be wall mount-
ed, using the mounting holes located in the unit's back plate.
All screen erasers must be plugged into a grounded electrical outlet.
Sample Exposure Cassettes
The exposure cassettes do not require any power and can be placed in any convenient
location where radioactive samples are normally handled. If desired, the exposure peripherals
can be stacked or placed directly on top or under the laser scanner to conserve bench
space.
3.1.2 AC Power Requirements
The scanner and all powered peripherals including the host computer should be connected
to a stable grounded power outlet on a circuit free of electrical noise. In addition, a high
quality electrical surge suppressor/line filter with a 10 Amp or higher rating should be used
to avoid damage from AC fluctuations. Only a grounded 3-pin power cord should be used
to connect power.
The scanner is designed for input voltages of 100–240 VAC at 50-–60 Hz, and requires no
voltage setting or fuse change before operation.
The screen eraser is configured for 100–120 VAC, 50–60 Hz or 200–240 VAC, 50–60 Hz
operation. Please ensure that your eraser is configured to the appropriate voltage and fuse
settings before operation by checking the identification and settings label next to the power
input.
The External Laser Module must be configured for the proper voltage/current settings. This
should be done by appropriate Bio-Rad Service personnel only, as damage could result if
the settings are incorrect.
If the power setting on the Eraser or External Laser Module is incorrect, please contact
your local Bio-Rad representative.
