    Troubleshooting Communication Er-04 (Low water Level Alarm-tUL)) It is an alarm generated to prevent the mechanical seal from being damaged due to running of the pump when there is no water on the suction side. It is generated when the low levelsensor (electrode) does not detect the water. In case Cause of not using the low water level sensor, the software generates the alarm when the current pressure is maintained under the low pressure alarm level (Pr-75)and operation continues for low pressure trip time(Pr-74).
