7 Troubleshooting
Message/Indicator
Description
Resolution
Fail/
Out
of Range
The TEACH failed, the target is out of range. The target
might have moved out of range after the TEACH
process began.
TEACH the target within the measurement range.
Fail/
OfSt Out
of Range
The TEACH failed. The target is in range but the offset
value caused the setpoint(s) to be out of range.
Adjust the offset value or target distance to keep the setpoint(s)
within the measurement range.
MIN Wnd
xx mm (xx in)
The adjusted or taught window size is too small; the
minimum window size is displayed.
The sensor automatically adjusts the window size to maintain
the minimum window size and completes the adjust or TEACH
operation.
xxxx
< NEAR
The threshold (xxxx) is less than the minimum sensing
range. xxxx could be 4mA Pt (0V Pt), 20mA Pt (10V Pt)
or SPt1.
The desired window size is maintained, but the usable portion
of the window is restricted to be within the defined sensing
range.
xxxx
> FAR
The threshold (xxxx) is greater than the maximum
sensing range. xxxx could be 4mA Pt (0V Pt), 20mA Pt
(10V Pt) or SPt2.
The desired window size is maintained, but the usable portion
of the window is restricted to be within the defined sensing
range.
OutRnge
The target is out of range, too dark, or the sensor is not
measuring.
Move the target within the measurement range.
< NEAR
During RUN mode the target is detected, but is inside
the NEAR measuring range.
The sensor can reliably detect targets up to the face of the
sensor, and the Discrete Output state is valid. The Analog
Output cannot be used to measure distances inside the NEAR
measuring range.
Power LED is flashing green
The sensor input is set to laser enable and the input is
not active.
on p. 21.
All LEDs are flashing
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.
Contact Banner Engineering to resolve.
Type
Sync Slave
The slave mode sensor does not see the master's
pulse.
Make sure that the master mode sensor is configured and
functioning properly. Check the input wire connection between
the master and slave.
