To Next PageTo Next PageWhat to do if the Ebtron GTx116 Transmitter Status LED is flashing at 2-second intervals?
If the green Transmitter Status LED is flashing at 2-second intervals, it indicates that the sensor detection system has detected trouble. First, check the sensor probe cable connections. Also, ensure that the correct type of sensor probes are attached to the transmitter; the GTx116 transmitter only operates with GP1 or GB1 sensors connected.
How to troubleshoot an Ebtron Transmitter with no LCD display and a non-illuminated green status LED?
If there is no LCD display indication and the green Transmitter Status LED on the main circuit board is not illuminated, ensure the power switch is in the "ON" position. Check that 24VAC power is correctly connected to L1 and L2 of the POWER terminal block, and the voltage is between 22.8 and 26.4 VAC with the power switch on. Also, inspect the fuse and replace it with a 1.5 amp, fast-acting fuse after identifying and correcting any power wiring issues, such as multiple devices wired on a single transformer being out-of-phase.
Why is the green Transmitter Status LED on my Ebtron GTx116 Transmitter on but not flashing?
If the green Transmitter Status LED on the main circuit board is "ON" but not flashing, it suggests that the microprocessor is not running. To resolve this, reset the 24VAC power by moving the power switch from the "ON" to "OFF" position and then back to the "ON" position.
What to do if Ebtron GTx116 indicates airflow when the HVAC system is off?
If the Ebtron Transmitter indicates airflow when the HVAC system is off, it's because the sensors are highly sensitive and can measure very low air velocities. If a reading is indicated, there is airflow present where the airflow measuring station is located. Do not attempt to adjust zero ("offset"), as this will cause airflow measurement errors. Instead, set the Low Limit airflow cutoff value to force the output signal to zero.
