VS1CTD Trickle Current Heating
•Trickle Current Heating is used to keep the
temperature of the motor above the dew
point during times when not in use.
•Set by a single parameter (units of amps)
–Limited to 50% FLA of motor (0 amps disables)
–Wattage calculation based upon amperage
and motor stator resistance
•Enabled automatically once motor stops and
after a 300 second delay
–Digital input provided for customers that want
control via hardware input for CTD operating modes
–Modbus coil provided for building automation
control systems
•Additional benefit of providing anti-windmilling torque
NO SPACE HEATERS REQUIRED
