How to troubleshoot no 4-20mA signal on Limaco Transmitter?
If the Limaco Transmitter shows no 4-20mA signal, first, check the power supply and electrical connections to ensure they are within acceptable values. If the connection is damaged or the line resistance is too high, restore the connection or reduce the load. If the problem persists, the electronic unit may be malfunctioning, requiring the device to be sent for repair.
What to do if 4-20mA signal corresponds to alarm values in Limaco ULM-3D Transmitter?
If the 4-20mA signal on your Limaco Transmitter corresponds to an alarm value, it indicates that one or more monitored parameters are outside of tolerance. Use a PC or console to connect to the level transmitter and check the match between the alarm value and its mask. Other potential causes include temperature outside the acceptable range (eliminate overheating, isolate from high temperatures, provide cooling, or install a sun visor), deviation from the vertical axis (align the device), or a meter malfunction (send the device for repair). It can also be caused by the lack of stability of readings. In this case, a reference parameter operation can be continued, or unstable mode. In this case you should contact the technical support.
