This alarm indicates when the water injection sensor is damaged or broken. This alarm indicates when there is a census or water flow problem. This alarm usually appears together with the A10 alarm as it depends on the configuration at which the pump was com- missioned, otherwise the current equipment containing this controller simply has a pump configured in this case this alarm goes together with the current pump configuration.
