Pump Control
Designed to prevent over-pressure during starting, and water-hammer during stopping. Six field-adjustable starting and stopping curves with adjustable final torque point.
Typical applications: Pumping to a high elevation or against counter torque. 

Jog with Electronic Reverse
Motor can be operated at 1/6 of rated speed for 30 seconds. Direction is reversed electronically, without contactors.
Typical applications: Positioning, maintenance and sewage pumps-releasing jam conditions by reverse rotation. 

Energy Saver
Supply voltage to the motor is reduced when motor is lightly loaded. The RVS-DN lowers the rotating magnetic field intensity, improving the power factor and reducing power consumption.
Typical applications: Piston Compressors operating less than 50% of the duty cycle in less than 50% of their FLA current. 

Auxiliary Relays
Programmable relays, 3 Form C, 8A, 220 VAC

• Immediate with adjustable on and off delays, can be dedicated for shear-pin (jam) protection
• End of acceleration with adjustable “on” delay
• Fault, programmable as fault or fault fail-safe operation
• Low motor insulation alarm (optional) Optional Communication Protocals

Optional Communication Protocols

• MODBUS-enables setting, control and supervision
• PROFIBUS DP-enabling control and supervision
• MODBUS-TCP/IP- supported according to “Specification 1.0,” via standard RJ45 computer network connector (TBD)

Optional Analog Board
Two field programmable functions:

• Thermistor input, PTC or NTC
• Analog output, related to motor’s current, programmable as 0-10VDC, 4-20mA, 0-20mA

• Alarm level, adjustable 0.2-5 MΩ
• Fault level, adjustable 0.2-5 MΩ, prevents starting when insulation is below an acceptable level
