Banner U-GAGE QT50U Ultrasonic Sensors - Manual (Page 4)

NOTE:
• If temperature compensation is enabled, exposure to direct sunlight can affect the sensor’s
ability to accurately compensate for changes in temperature.
• With temperature compensation enabled, the temperature warmup drift upon power-up is less
than 0.8% of the sensing distance. After 15 minutes, the apparent switchpoint will be within
0.5% of the actual position. After 30 minutes, the apparent switchpoint will be within 0.3% of
the actual position.

OUTPUT 1 - Output 1 Indicator
POWER - Sensor power indicator
SIGNAL - Target signal strength indicator
OUTPUT 2 - Output 2 indicator
Signal LED (Red) – Indicates the strength and condition of the sensor’s incoming signal
Signal LED Status Indicates
ON Bright Good signal
ON Dim Marginal signal strength
OFF No signal is received 2 or the target is beyond the sensor’s range limitations
Output LEDs (Amber or Red) – Indicate the position of the target, relative to the window limits
Output/Teach LED Indicates
ON Red (Solid) In Teach mode; waiting for first limit to be taught
ON Red (Flashing) In Teach mode; waiting for second limit to be taught
ON Amber Target is within window limits (normally open mode)
OFF Target is outside window limits (normally open mode)
Power ON/OFF LED (Green) – Indicates the operating status of the sensor
Power ON/OFF LED Indicates
OFF Power is OFF
ON Solid Sensor is operating normally
Flashing at 4 Hz Output is overloaded (RUN mode)
Flashing at 2 Hz Transmit disabled
2 If no signal is received, the output will react as if the target is beyond the far limit. In normally open mode, the outputs will be
OFF. In normally closed mode, the outputs will be ON.
