Why Honeywell Transmitter has no input or low input?
If you're experiencing no input or low input on your Honeywell Transmitter, the issue could stem from a faulty sensor wire connection or an incorrect operating voltage. First, carefully inspect the field wiring and connections. Then, make sure the transmitter is operating within its correct voltage range. Lastly, check that the 250 ohms resistor is properly installed in the loop.
What to do if Honeywell Transmitter shows high input?
If your Honeywell Transmitter shows high input, it might be due to a bad sensor wire connection. Inspect the field wiring and connections for any partial short circuits. Also, verify that the transmitter operates within its specified voltage range.
