Non-Contact Displacement Sensor User’s Manual Rev 1.00

Appendix 

 

6-1. 

Troubleshooting 

 

Symptom 

Check 

Action 

The status 

indicator does not 

turn on. 

Is the power turned on? 

Turn on the power. 

Is the power cable correctly 

connected? 

Connect the power cable correctly. 

The error indicator 

is lit on. 

－

 

Use the Non-Contact Displacement Sensor 

software to check the content of the error, and 

take action accordingly. 

The error indicator 

is blinking. 

－

 

A warning has occurred. Use the Non-Contact 

Displacement Sensor software to check the 

content of the warning, and take action 

accordingly. 

The length 

measurement 

value seems 

wrong. 

Is the main unit mounted in the correct 

direction to the moving direction of the 

target measurement object? 

Mount the main unit in the correct direction to the 

moving direction of the target measurement 

object? (See 1-4-2) 

Is the measurement distance 

adjustment tool inserted? 

Length cannot be measured if the measurement 

distance adjustment tool is inserted. After 

installation and adjustment are complete, remove 

the measurement distance adjustment tool. 

Is the target measurement object 

placed within the measurement 

distance of the main unit? 

Place the target measurement object within the 

measurement distance of the main unit. 

Is the main unit mounted with an angle 

to the target measurement object? 

Mount the main unit horizontally to the target 

measurement object. 

(An approximate guide is ±2°.) Alternatively, follow 

2-3. Calibration to correct the length measurement 

value. 

Is the width of the target measurement 

object small (20 mm or less) and out of 

the light receiving area? 

Place the target measurement object within the 

light receiving area. 

* The measurement distance adjustment tool 

makes it easier to place the object. 

Is the optical window dirty? 

Remove dirt. 

Is the optical window scratched or 

broken? 

The optical window needs to be replaced. We will 

fix it. Please contact our customer support. 

Is there strong ambient light? 

Block ambient light. 

Is the main unit or target measurement 

object vibrating? 

- If the main unit vibrates independently of the 

target measurement object, it detects a motion 

other than that of the target measurement object, 

and the error becomes large. 

- If the target measurement object vibrates or 

meanders, only the length measurement direction 

is detected from the tracks of the target 

measurement object, and the error becomes large. 

If the target measurement object vibrates beyond 

the tolerance of the measurement distance, the 

error becomes large. 

Has condensation occurred? 

The equipment cannot be used stably if 

condensation occurs. 

Is the ambient temperature out of 

specifications? 

Use the equipment within the specified 

temperature range. 

Is there a hole on the target 

measurement object? 

If there is a hole larger than the light receiving 

area on the target measurement object, the length 

cannot be measured due to the hole. (A warning is 

output.) 

- Install the equipment again so that the range to 

be measured and the hole do not match. 

Light beam is not 

emitted. 

Are the USB cable and I/O cable 

correctly connected? 

Connect the USB cable and I/O cable correctly. 

Is the length measurement start trigger 

correctly input? 

Input the length measurement start trigger 

correctly. 

See 2-2-2. Setting the trigger. 

Pulse is not 

correctly output. 

Is the wiring correct? 

Check the wiring and connect the cables correctly. 

Is the response frequency of the 

counter exceeded? 

If the target measurement object moves fast 

(4,000 mm/s or faster) and the pulse resolution is
