1. A fluid processing device, comprising:
a detection assembly including
a light source associated with a component of the fluid processing device, provided in an initial position with respect to said component of the fluid processing device, and configured to emit a light,
an actuator associated with the light source and configured to adjust the position of the light source with respect to said component of the fluid processing device, and
a light detector configured to receive at least a portion of the light from the light source and generate a signal indicative of the amount of light received by the light detector; and
a controller configured to receive the signal from the light detector and control the actuator to move the light source with respect to said component of the fluid processing device to a monitoring position based at least in part on the signal, wherein the initial position of the light source is controlled by the controller in combination with the actuator to be a non-monitoring position in which the light emitted by the light source is not received by the light detector.
