Preparation for bypass - to maintain
protection when bypass is closed
Special anti-corrosive treatment - special coating
for harsh environments
Special tacho feedback circuitry
Modbus RTU - enables setting, control &
supervision
Profibus DP – enables setting, control &
supervision
Analog Card (Optional)
Incorporates two functions:
Thermistor input, PTC or NTC
Analog output, related to motor's current,
programmable as 0-10VDC, 4-20mA, 0-20mA or
inverse (inverse available in RVS-DN 1000V& RVS-
DN1200V models)
Motor Insulation Tester (Optional)
A unique feature for submersible pumps, motors
installed in harsh environments, etc.
The system measures motor insulation when motor is
not running.
Two programmable levels are available:
Alarm level, adjustable 0.2-5 Mohm
Start disable level, adjustable 0.2-5 Mohm,
preventing starting when insulation is below
acceptable levels
Auxiliary Relays
Three standard programmable relays (each relay with
one C.O. 8A, 220VAC contacts)
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 relay)
