To Next PageTo Next PageWhat to do if the Power LED (green) is OFF on my Honeywell Controller?
If the green Power LED is OFF, it indicates a problem with the power supply. Check the power supply voltage and wiring. If the problem persists after checking these, the hardware may need to be replaced.
Why is the L2 LED OFF on my Honeywell CENTRA LINE EAGLEHAWK NX Controller?
The L2 LED being OFF indicates that the station is not running. To resolve this, start the station or enable auto-start.
What does it mean if Rx is flashing and Tx is OFF on my Honeywell CENTRA LINE EAGLEHAWK NX?
If the Rx is flashing and the Tx is OFF, try switching ON communication on RS485-1. If this doesn't work, the hardware may be defective.
What does it mean if Tx is flashing and Rx is OFF on my Honeywell Controller?
If the Tx is flashing and the Rx is OFF, the communication rate (kbps) on RS485-1 may not be correctly set. Other controllers on the bus may have been incorrectly assigned the same device number, or there could be a wiring problem or hardware defect.
What to do if the Status LED (red) is continuously ON after power-up on my Honeywell EAGLEHAWK NX Controller?
If the red Status LED is continuously ON after powering up, try powering down and then powering up the EAGLEHAWK NX controller again. If the problem continues, the hardware may need to be replaced.
