What does THERMO MOT/EXT ERROR 15 mean on my Xylem Water System?
THERMO MOT/EXT ERROR 15 on your Xylem Water System indicates that the PTC sensor has reached its release temperature. Close X1/PTC if there is no external protective device connected.
What causes OVERLOAD ERROR 12 on a Xylem Water System and how to fix it?
OVERLOAD ERROR 12 on your Xylem Water System means the power limit has been exceeded because the motor current is too high. Here's what to check: 1. Verify if parameter P215/P220 RAMP 1/RAMP 2 is too short and P265 BOOST is too low. 2. Ensure the cables and connections are working correctly. 3. Check if the pump is blocked. 4. Confirm the motor rotates in the correct direction. A non-return valve defect could cause it to rotate the wrong way before running. Also, ensure that the operation point is allowed and P245 MAX.FREQ. is not too high, and check the P265 BOOST value.
Why am I getting OVERVOLTAGE ERROR 13 on my Xylem Water System?
OVERVOLTAGE ERROR 13 on your Xylem Water System indicates that the voltage is too high. To resolve this, check if parameter P220 RAMP 2 is set too fast and whether the power supply voltage is too high. Also, verify if there are excessive voltage peaks. If the error is power or voltage-related, consider installing line filters, line inductors, or RC-elements.
How to fix INVERT. OVERHEAT ERROR 14 on Xylem HVL 2.015-4.220?
INVERT. OVERHEAT ERROR 14 on your Xylem Water System indicates that the temperature inside the unit is too high. Ensure the unit is properly cooled, the motor vents are not contaminated, and the ambient temperature is not excessively high.
What does PHASELOSS ERROR 16 mean on my Xylem HVL 2.015-4.220 Water System?
PHASELOSS ERROR 16 on your Xylem Water System indicates that one phase of the power supply is not working. Check the power supply under full load, verify for phase failure at the input, inspect the circuit breakers, and visually inspect the points at the input terminals.
Why is the system pressure not steady in my Xylem HVL 2.015-4.220?
If the system pressure of your Xylem Water System is not steady, it could be due to the pressure being higher than the START VALUE or the REG. MODE being changed to Inverse. Check parameter P04 START VALUE and/or P320 REG. MODE.
Why is my Xylem HVL 2.015-4.220 Water System showing UNDERVOLTAGE?
To address an UNDERVOLTAGE issue with your Xylem Water System: * Check if the supply voltage is too low. * Verify if there is a phase failure at the input. * Check for asymmetry between the phases.
What does COMM LOST mean on my Xylem HVL 2.015-4.220?
If your Xylem Water System experiences COMM LOST, it means the communication between the power unit and the control board is not working correctly. Verify that the connection between the control board and the power unit is properly established.
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.
