How to troubleshoot no 4-20mA signal from Limaco Transmitter?
- SSally PowellAug 10, 2025
If the 4-20mA signal is not being delivered, check the transmitter's power supply and electrical connections to ensure they meet specifications. If abnormalities are found, correct them. Also, verify the 4-20mA output electrical connection isn't broken or has excessive line resistance; reconnect the line or reduce the load if needed. If these steps don't resolve the issue, the transmitter electronic unit may have failed, and the device should be returned for repair.
