DEPR/DEPRT EQUALIZATION PUMP CONTROL SEQUENCE OF OPERATION

The pump control panel shall be equipped with four float switches to control the timed doses to be discharged. The water level must be high enough to overcome the "Redundant Off" (Bottom) float in order for the pumps to be permitted to run. When the water level rises high enough to overcome the "Dose Enable" (second) float and the time clock is in a pump enable mode (pins pushed in), the lead pump will activate. The lead pump shall continue to run for the length of time as programmed on the pump run timer, and shall then shut off. The pump controller will rotate the lead pump at the end of each pump cycle. The pumps shall remain off until the time clock enters a new pump enable mode, at which time the lead pump shall activate (as long as the "Dose Enable" float is still up) and will run until the pump run timer finishes timing out. The pump run timer shall continue to operate a full pumping cycle even when the "Dose Enable" float drops to the off position. This process shall repeat until the water level drops below the "Dose Enable" float and the pump has timed out. Should either pump fail to run when called for, the pump fail circuit shall remove the failed pump from service and activate the audio/visual alarm. The alarm shall remain latched in until manual reset. The control system shall include an alternator override switch to allow for manual selection of the lead pump if necessary, and will be setup such that it will not interfere with the normal timing functions of the system.

The control system shall be equipped with a timer override circuit to manage peak flows and excess water use. If the water level continues to rise enough to overcome the "Timer Override" (third) float and the override selector switch is on, the pump shall be activated, regardless of the time clock position. The pump will continue to run until deactivated by the override circuit, at which time the pump will shut off and the normal pumping cycle shall resume. If the water level continues to rise enough to overcome the "High Level" (fourth) float, the audio/visual alarm shall activate and remain latched until the silence switch is pressed. When the silence switch is pressed, the audible alarm shall be silenced and the top mounted alarm light will remain lit until the water level drops below the "High Level" float, at which time the alarm circuit must be manually reset.
