The Hawk Alarms page is designed to assist the operators in the field while they work seamlessly in conjunction with technicians in the Adenus office. The initial goal is to provide the operators with all resources available to them so they can efficiently and successfully keep pace with field demands. Our goal is to make this a live page and to encourage operators to add their experiences and knowledge to help benefit others in the field.

Pump Stations (PS)

Low Level Water Alarms

A Low Water Alarm is usually indicative of the water level in a holding tank reaching a level below what is considered safe. This can put the pumps at risk of overheating if there is insufficient liquid level for their operation.

High Level Water Alarm

A high level water alarm will occur when the top float is up and there are high water conditions.

Float Error Alarm

A Float Error occurs when an impossible float condition is reported, such as the top float reporting up and the bottom float reporting down. These conflicting signals will cause the PLC to send the error message.

No Current Alarm

The No Current Alarm will occur when a pump is expected to be running and no amps are registered by that pump's current sensor. This alarm is tripped after a minimum amount of time (typically 2 seconds) has passed from the program issuing the pump on command.

Stuck ON Alarm

The Stuck ON Alarm will occur when a pump is expected to have turned off and amps are still being registered by that pump's current sensor. This alarm is tripped after a minimum amount of time (typically 2 seconds) has passed from the program issuing the pump off command.

OL Tripped Alarm

The Overload Tripped Alarm occurs when the pump is pulling too many amps or gets overheated.

Low Amps Alarm

A Low Amp Alarm occurs when the pump is pulling less than the Minimum Normal Amps. The normal operating range for amperage can be determined by the HP and GPM ratings for the pumps installed at the site.

High Amps Alarm

A High Amps Alarm will occur when the pump is pulling more than Maximum Normal Amps. The normal operating range for amperage can be determined by the HP and GPM ratings for the pumps installed at the site.

Recirculating Sand Filters (RSF)

Recirc High Level Alarm

A Recirc High Level Alarm occurs when the water level sensor (top float or ultrasonic level sensor) in the recirc tank detects that the water has risen above what was determined to be a safe operating level. Operating above this level has several drawbacks; a sustained high level condition interferes with the biological process of the "bugs" ability to consume the "food" in the water by removing the opportunity for oxygen to exist in the media spaces. RSFs with chronic high level conditions can over time saturate the media and grow a biomat within the media bed.

Recirc Low Level Alarm

Water level in recirculation side of RSF is below preset designated low level.

Discharge High Level Alarm

Occurs when the water level on the final dose side is above preset level.

Discharge High Level Solutions


Discharge Low Level Alarm

A Discharge Low Level Alarm occurs when the water level sensor (bottom float or ultrasonic level sensor) on the final dose side or discharge tank detects that the water has dropped below what was determined to be a safe operating level. Operating below this level may put the discharge pumps in danger of sucking air or burning up due to lack of water intake.

Recirc Float Error

The Recirc Float Error will occur when there is an impossible level condition being reported by the floats. Examples of an impossible level condition would be the middle float reports UP while the bottom float reports DOWN, or the middle float reports DOWN while the top float reports UP. Sites that house the recirc middle float inside the filter and the top/bottom floats in a settled or below grade recirc tank are the most difficult to accurately set floats and therefore are the most prone to this.

Discharge Float Error

The Discharge Float Error will occur when there is an impossible level condition being reported by the floats. Examples of an impossible level condition would be the middle float reports UP while the bottom float reports DOWN, or the middle float reports DOWN while the top float reports UP.
