Monarch Instrument IRS - Manual (Page 2)

PREPARATION FOR USE:
In order for the sensor to work, you are required to have a contrasting color target on the rotating part. NOTE: Standard Monarch reflective
tape will not work. The target can be any white surface that will reflect the infrared. A solution that works well on small high-speed shafts is wax
crayon. Use black or white paint/ink to coat the shaft, 2/3 black and 1/3 white, so that as the shaft rotates the colors alternate in front of the sensor.
White paper labels also work when wrapped fully around the shaft and then part of the label is blackened out with a marker. The sensor can also
target off gear teeth, objects 0.039 inch [1 mm] diameter, slots, bolt heads and keys.
CAUTION: Centrifugal Force at high speeds can be dangerous. Ensure all targets are adequately secured to shafts and always have
operators protected by a sheet of Plexiglas at least 0.5 inch [12 mm] thick.
NOTE: In order for the IRS to be fully CE compliant, the supplied ferrite must be attached around the plug/wire end of the cable.
OPERATING INSTRUCTIONS:
The user must mount the IRS to obtain an accurate measurement. The ideal focal point of the sensor is 0.5 inch [12 mm], but this is dependent
on the size and speed of the target. The sensor has a green LED On-Target Indicator that indicates when it is picking up a valid signal. The green
LED will blink on and off at slow speeds and remain on steady at high speeds. Use this to properly place the sensor, as you cannot see the
infrared emissions. NOTE: The sensor is sensitive to lighting, such as fluorescent lamps or sunlight. If the system appears to read a speed when
the shaft is stationary, it may be necessary to shield it from ambient lighting.
