How to resolve SETPOINT 2 I < 4 mA, SETPOINT 2 I < 4 mA ERROR 26 on Xylem HVL 2.015-4.220?
SETPOINT 2 I < 4 mA, SETPOINT 2 I < 4 mA ERROR 26 on your Xylem Water System indicates that the current signal input of required values is active, but no signal between 4-20 mA is connected. Check the external analog signal on terminals X3/22-23 and the configuration of the required values in P800 SUBMENU REQUIRED VALUES.
What does CODE ERROR mean on my Xylem HVL 2.015-4.220 Water System?
If you encounter CODE ERROR on your Xylem Water System, it indicates an invalid processor command. Ensure the installation of the cables, the screen connection, and potential equalization are correct. Also, verify that the ground is correctly installed and that the signal is strong enough; if not, install additional ferrite inductances to boost the signal.
What does ERROR 1 mean on my Xylem HVL 2.015-4.220 Water System?
If your Xylem Water System displays ERROR 1, it means there is an EEPROM-ERROR, indicating a data block malfunction. Try resetting the unit. If the error message persists, the control board needs to be changed.
What does ERROR 5 mean on my Xylem Water System?
If your Xylem Water System displays ERROR 5, it means there is an EPROM-ERROR, indicating a checksum error. Try resetting the unit. If the error message persists, the control board needs to be changed.
