Checking The Machine’s Onboard Sensors

The status of each of the machine’s onboard sensors can be accessed

from the LCD screen and keypad for the purpose of troubleshooting. To

access the Sensor Check menu simply select the “0” (Options) key at the

CarveWright Main Menu or use the up/down arrows to locate the

Configurations Menu and then press ENTER. Next, select the “7”

(Measure) key or use the up/down arrows to locate the Sensor Check

menu and then press ENTER. Navigate through the different sensors and

associated status values using the up/down arrows.

Cover Switch

State - Open/Closed

The cover switch monitors the state of the front safety cover. For safety

all power to the cut motor is removed if the cover is opened. Test this

switch by opening and closing the front cover. The displayed state will

toggle from Open to Closed if the switch is operating correctly.

Front Roller/Back Roller

State - Released/Compressed

These sensors monitor the deflection of the rollers mounted used to press

down on the workpiece and keep it flat on the sandpaper drive belts. The

state of the roller can be Released or Compressed. These sensors read

Compressed when the head is cranked down with a workpiece installed in

the machine. Both the front roller sensor and back roller sensor are

required to read Compressed in order for the machine to start the

program. To check these sensors crank the head up, reach underneath,

find the compression roller (front or back), and press upward. The

displayed state will toggle from Released to Compressed.

Board Sensor

State – Values from 0 to 255 (typical max of 170)

The board sensor is used to find the edges of the workpiece. It is a

reflective sensor and works by emitting light and monitoring the amount of

reflected light entering the sensor detector. If the sensor is reading low

due to dust or defect then it may not operate. The procedure for checking

and troubleshooting the board sensor can be found in the Troubleshooting

section.

Y position

State – Numerical Value (0.000)

The Y position sensor monitors the relative position of the side-to-side

motion of the cutting truck. To check this sensor move the cutting truck all

the way to the left hand side of the machine and record the displayed

numerical value. Now move the truck all the way to the opposite side and

back to the left side. If the sensor is operating correctly the displayed

value will match the one previously recorded.
