TROUBLESHOOTING GUIDE
Understanding System LEDs
• Monitor LEDs
• The STATUS LED blinks yellow if an error occurred that caused the monitor to report a
significant Diagnostic Trouble Code and go into safe mode. (The reported error is described
through the EXM2 web interface accessed over Wi-Fi.) The blink pattern indicates the condition.
The blinks will continue until the monitor control box is reset (power-cycled). The blink pattern
is as follows:
Status Blink Pattern Reason for Safe Mode Solution
2 blinks continuous Not Calibrated Complete Installation Step 3
3 blinks continuous Sensor Failure Check wires of the sensor for any damage.
Ensure the wires are completely plugged
into the control module (Wiring diagram is
located at www.elkhartbrass.com). Order a
replacement at Elkhart Brass
4 blinks continuous. Sensor indicates that monitor is moving in
the opposite direction of the expected.
Check wiring diagram at
www.elkhartbrass.com for motors location.
5 blinks continuous Sensor did not detect movement on motor
when power was applied to either vertical or
horizontal motors.
Ensure monitor has power. Check wiring for
damage. Order new motors.
• Other LEDs may blink a pattern if an error occurred. The pattern is described in the following
table. The monitor is not in safe mode for these errors. The blinks remain until the monitor is
reset (power-cycled). (The reported error is also described in the EXM2 web pages accessed
over Wi-Fi.)
Blink Pattern Reason for Notication
Cycle FOG-STREAM and LEFT-RIGHT LEDs (inside 2 of the
four LED’s grouped on the monitor control box)
Temperature inside the module over 185 degrees F (85
degrees C)
Cycle UP-DOWN and AUX LED’s (outside 2 of the four
LED’s grouped on the monitor control box)
During movement of the monitor, the monitor’s input
voltage dropped below 10 VDC.
• Panel Mount STATUS LED
• Color meanings:
• Yellow = a DTC error has occurred
• When not moving or pushing buttons with Wi-Fi off, the STATUS LED blinks a yellow pattern if
an error occurred that cau sed the monitor to report a significant Diagnostic Trouble Code and
go into safe mode. (The reported error is described through the EXM2 web interface accessed
over Wi-Fi.) The blink pattern indicates the condition. The blinks will continue until the panel
mount is reset (power-cycled). The blink pattern is as follows:
