The limit switch at the end of the conveyor belt will stop the motor if a core
passes through it during a test. If the belt does not stop when a core reaches
the end of the belt, check the following:
1. The limit switch is disabled during both spectral and motor calibrations.
Make sure the software is in Test mode and not Calibration mode.
2. Turn the Limit Switch option on. See page 16.
3.
Confirm the size of the core. The limit switch will not detect cores smaller
that 2" in diameter. If the core is less than 2" in diameter, the operator
must remove it manually before it reaches the end of the belt.
4. Check sensor operation:
a. During normal operation a red light on the transmitter and green light
on the receiver should both be on. If one or both is not on, the system
must be serviced by an OFITE technician.
