Bio-Rad EXQuest Spot Cutter - Manual (Page 12)

1.2.9 Sensors
The spot cutter includes a series of sensors to protect the operator and ensure the proper operation of the
instrument.
• Front Door Sensor: When this sensor detects that the front door is open, it turns off the UV EPI
fluorescent lights, causes the spot cutter to operate at reduced speed and prevents images from
being taken.
• Water/Waste Bottle Door Sensor: When this sensor detects that the bottle door is open it pauses the
instrument.
• UV Light Sensor: This sensor determines if the UV lights are on and ready before acquiring an
image.
• Waste Reservoir Level Sensor: This sensor activates the waste pump when the wash port reservoir
is full.
• DI Water Sensor: This sensor is used to warn the operator that the water level is low.
• Waste Sensor: This sensor is used to warn the operator that the waste bottle is full.
• Tray Sensor: This sensor is used to warn the operator that the gel tray is not installed. A cut run
cannot be started if the tray is not fully inserted.
