Piranha ultima pump controls

Description: Circuit breaker, magnetic contactor, H-O-A selector switch, solid state power monitor with programmable power-on timer 2-500 minutes with LED fault display, optional computer interface with fault display software, in a NEMA 4X enclosure. Fully programmable to shut down and automatically re-start your pump for any of the following conditions: over current, under current, single phasing, contactor failure, ground fault, high voltage, low voltage, voltage unbalance, current unbalance, and phase reversal.

When a fault condition occurs for any reason, the pump will power-off, identify the fault condition in the LED display, and automatically re-start the pump at the time interval you have defined in the power-on timer (2-500 minutes). If the fault condition still exits, the pump will immediately shutoff again, engage the timer, and so on. Thus preventing expensive damage to your pump.

Over current protection: Over current is usually set at the service factor amperage of the motor. If any one leg of current exceeds the setting, the unit will start its trip delay timer. If your pump motor is drawing too many amps it will cook the insulation in your motor windings and destroy the motor. Some of the most common causes for over current are: low voltage, wet motor, or excessive drag on the impeller from high solids content in the pump case, high fluid specific gravity, foreign objects in the pump case, or damaged suction case liner. The Ultima pump control can be tuned to the normal load conditions for your pump, so that it senses when too much current is being drawn by the motor. When an over current condition occurs for any reason, the pump will power-off, identify the fault condition in the LED display, and automatically re-start the pump at the time interval you have defined in the power-on timer.

Under current protection: Undercurrent is usually set at 80% of the full load current. This condition is when your pump is drawing fewer amps than it should in your particular application. This usually means that the pump is running dry. This feature serves as a liquid level control in that it will only allow the pump to operate when water is present. Then by adjusting the re-start interval in power-on timer, the pump will power-on periodically and run only as long as water is present.

Single phasing: Three phase motors have three power leads. If power is lost to any one of the power leads the motor is "single phased". Single phasing will burn your motor up in a very short period of time. Single phasing can be caused by human error or component failure anywhere upstream from the pump control, all the way back to the original power source (your generator, or the power company itself). Your Ultima control shuts off the power to your pump when this disastrous conditions occurs.

High/Low Voltage: This is usually set at plus or minus 10% of the nameplate voltage, as greater variations in voltage may damage your motor.

Voltage Unbalance: Voltage unbalance is usually set at 5%. A greater voltage disparity between the three power leads may damage your motor.

Current Unbalance: Current unbalance is usually set at 5%. A greater current disparity between the three power leads may damage your motor, or may be indicative of existing component damage thus preventing further damage.

Phase Reversal: Phase reversal means running the pump in reverse rotation. This is the single most common pump failure, and it is always catastrophic. This happens when the installer fails to check rotation when power is initially applied to the pump. Rotation and start kick are clearly marked on all of our pumps. You would be surprised how many people neglect to check rotation when installing a pump. In any three phase motor and most single phase motors, there is a 50/50 chance of the motor running in the proper direction when power is initially applied. The problem is that centrifugal pumps do pump water in reverse rotation. Most installers are ignorant to this little known fact. Therefore, the assumption is made that if water flows out the discharge, then the rotation must be correct. Reverse rotation will completely destroy a pump, usually within few days, and sometimes in a matter of hours. Even the most knowledgeable & experienced pump people are susceptible to occasionally making that mistake. This problem is most prevalent in portable pump applications, since the pump is connected and re-connected to power many times. Once the Ultima pump control has been set for proper rotation to your pump, you will never have to check for proper rotation again. The Ultima pump control will not allow power to the pump when the power phases are incorrect, and will display a fault condition.
