Troubleshooting
Description
The TEACH failed, the target is out of range. The target
might have moved out of range after the TEACH
process began.
The TEACH failed. The target is in range but the offset
value caused the setpoint(s) to be out of range.
The adjusted or taught window size is too small; the
minimum window size is displayed.
The threshold (xxxx) is less than the minimum sensing
range. xxxx could be 4mA Pt (0V Pt), 20mA Pt (10V Pt)
or SPt1.
The threshold (xxxx) is greater than the maximum sens-
ing range. xxxx could be 4mA Pt (0V Pt), 20mA Pt (10V
Pt) or SPt2.
The target is out of range, too dark, or the sensor is not
measuring.
During RUN mode the target is detected, but is inside
the NEAR measuring range.
The sensor input is set to laser enable and the input is
not active.
The laser shuts off, the Power LED flashes green, the
Output LEDs flash amber at 1 Hz, and the display is
blank.
The sensor has experienced a fault.
The slave mode sensor does not see the master's
pulse.

Resolution
TEACH the target within the measurement range.
Adjust the offset value or target distance to keep the setpoint(s)
within the measurement range.
The sensor automatically adjusts the window size to maintain
the minimum window size and completes the adjust or TEACH
operation.
The desired window size is maintained, but the usable portion
of the window is restricted to be within the defined sensing
range.
The desired window size is maintained, but the usable portion
of the window is restricted to be within the defined sensing
range.
Move the target within the measurement range.
The sensor can reliably detect targets up to the face of the sen-
sor, and the Discrete Output state is valid. The Analog Output
cannot be used to measure distances inside the NEAR measur-
ing range.
See " Input Type " on page

Make sure that the master mode sensor is configured and func-
tioning properly. Check the input wire connection between the
master and slave.
