ROLS
Remote Optical Laser Sensor
SAFEGUARDS AND PRECAUTIONS:
Laser hazards
 Eye injury from beam - Do not look into the direct or reflected beam; can cause eye injury up to 25 ft (7.5 m)away.
 Visual interference (glare) with pilots and drivers - Interferes with vision up to 525 ft (160 m) away. Can be a
distraction up to 1 mile (1.6 km) away. NEVER point any laser towards aircraft or vehicles; it is unsafe andillegal.
Safe use guidance
Class 2 lasers are considered safe for accidental eye exposure. Do not look or stare into beam. Do not aim at aircraft.
This is not a toy. Always supervise children.
Read and follow all instructions in this instruction sheet carefully and retain this sheet for future
reference.
Do not use this instrument in any manner inconsistent with these operating instructions or under any
conditions that exceed the environmental specifications stated.
This instrument is not user serviceable. For technical assistance, contact the sales organization from which you
purchased the product.
DESCRIPTION:
The Remote Optical Laser Sensor has a visible red laser light source and green LED
on-target indicator. The class 2 laser source acts as the aiming device during setup
and can accurately measure speeds from 1-250,000 RPM from a distance of up to 25
feet with a maximum offset angle of 60 degrees from the rotating object. The sensor is
housed in a threaded 303 stainless steel tube and supplied with a 90-degree mounting
bracket, jam nuts and an eight foot shielded cable. ROLS-P comes with a 3.5mm (1/8”)
male stereo plug adapter. ROLS-W comes with 4 tinned wires.

OPERATING INSTRUCTIONS:
The ROLS Remote Optical Laser Sensor is capable of detecting a reflected pulse from a target consisting of T-5 Reflective Tape or high
contrast color differences (such as black and white) at distances up to 25 feet [7.6 m] from the rotating object and angles up to 60 degrees.
For most applications, a ½” [12 mm] square piece of Reflective Tape (T-5) should be applied to a clean area on the rotating object. At slow
speeds (<500 RPM) best results will be obtained by aiming the laser perpendicular (90°) to the target using a narrow piece of reflective tape –
typically 0.2 inch (5 mm) wide.
The ROLS should be mounted (using the supplied jam nuts and aluminum mounting bracket) and optically aligned to illuminate the on-target
indicator once per revolution. It is recommended that the optical sensor be placed at a slight angle (15 degrees) from perpendicular, so that
the sensor will receive only pulses from the reflective marker. Triggering from contrasting colors should be done perpendicular to the target.
The ROLS should be at least 1 inch from the reflective target to avoid false triggering. The green LED On-Target Indicator will blink at the
input frequency rate when the ROLS is properly aimed. NOTE: The green LED On-Target Indicator will blink on and off at slow speeds and
remain on steady at high speeds.
The ROLS is supplied with a 3.5 mm [1/8 inch] male stereo plug (ROLS-P) or an 8 foot [2.4 m] cable terminated with 4 tinned wires
(ROLS-W).The plug may be cut from the cable and the leads stripped and connected as shown in connection detail for tinned wires above.
An optional 25 foot [7.6 m] extension cable EC-25P is available with a female socket for the plug on one end and a 3.5 mm [1/8 inch] male
stereo plug on the other (for ROLS-P).
The ROLS-P will work directly with all Monarch handheld tachometers and stroboscopes that accept pulse input through an input jack (e.g.
PLT200, PLS, dax, dbx, DBL, pbx, PBL, Nova-Pro 300, Nova-Pro 500). The ROLS-W will work with all Monarch panel instruments that
accept pulse inputs (e.g. ACT Series, Frequency to Analog Converters, DataChart 1250, DataChart 6000) and vibration data collectors. A
sensor power supply (SPSR-IM) with BNC output is available for those applications that require a separate power source for the sensor
(ROLS-P only).
