The Nastec PILOT 112 is an advanced electronic controller designed to safeguard and manage single-phase and three-phase pump motors. This device offers comprehensive protection against various operational hazards, ensuring optimal performance and longevity of your pumping systems. Key Features: - Overcurrent Protection: The PILOT 112 continuously monitors the pump's operating current. If the current exceeds the user-defined threshold, the device automatically halts the pump to prevent potential damage from overcurrent situations. - Phase Loss Detection: This controller is equipped to detect phase loss, a common issue in three-phase systems. Upon identifying a phase loss, the PILOT 112 promptly stops the pump, safeguarding the motor from running under unfavorable conditions. - Excessive Start Prevention: Frequent starts can lead to motor wear and reduced lifespan. The PILOT 112 allows users to set a maximum number of starts, and if this limit is surpassed, the device intervenes to prevent potential damage. - Dry Running Protection: Operating a pump without sufficient fluid can cause severe damage. The PILOT 112 monitors the power factor (P.F. or cosø) and can be configured to stop the pump if the power factor falls below a predefined value, indicating dry running conditions. - Automatic Restart Attempts: In the event of an alarm condition, the PILOT 112 can attempt up to five automatic restarts at user-defined intervals, enhancing system reliability and reducing downtime. - Operational Logging: The device records the number of pump starts and total running hours, providing valuable data for maintenance scheduling and performance analysis. - Alarm History: An integrated alarm history feature assists technicians in diagnosing issues by storing past alarm events, facilitating efficient troubleshooting and service. Technical Specifications: - Voltage: 1 x 230 VAC ±10% - Maximum Current: 12 A - Weight: 2 kg - Protection Degree: IP55, ensuring resistance against dust and water ingress, making it suitable for installation in humid and dusty environments. - Ambient Temperature Range: Up to 40°C (104°F) - Altitude: Up to 2000 meters Additional Features: - Digital Inputs: Two digital inputs, configurable as Normally Open (N.O.) or Normally Closed (N.C.), allow for external control of the pump's operation, such as start/stop commands from float switches or pressure sensors. - Relay Output: A relay output is available for external alarm signaling, configurable as N.O. or N.C., to alert operators of any operational issues. - Capacitor Connections: For single-phase pumps, the PILOT 112 provides connections for starting capacitors, facilitating direct-on-line (D.O.L.) starting. The PILOT 112's robust aluminum housing ensures durability and efficient cooling, while its IP55 protection rating allows for installation in challenging environments. When combined with Nastec's VASCO series inverters, the PILOT 112 offers a comprehensive solution for direct-on-line pump starting, providing both operational control and protection. For enhanced motor startup performance, especially in cases of significant voltage drops, the AVIATOR electronic card can be paired with the PILOT 112. This combination increases the starting torque of single-phase motors in a simple and cost-effective manner. The AVIATOR card is available as an accessory and is compatible with the PILOT 118 model. In summary, the Nastec PILOT 112 is a versatile and reliable electronic controller that offers comprehensive protection and control for single-phase and three-phase pump motors, ensuring efficient and safe operation in various industrial applications.
