Overload circuit retains thermal condition of the motor regardless of control
power status. Unit uses real time clock to adjust for off time.
Overload will not reset until thermal capacity available in the motor is enough
for a successful restart. Starter learns and retains this information by
monitoring previous successful starts.
Imbalance Trip Level: 5 - 30% current between any two phases
Imbalance Trip Delay: 1 -20 seconds
Trip Level: 100 - 300% of motor FLA
Trip Delay: 1 - 20 seconds
Under Current Trip Level: 10 -90 % of motor FLA
Under Current Trip Delay: 1 - 60 seconds
Coast Down Time Range: 1 - 60 minutes
Range: 1 - 6 successful starts per hour
Time between starts: 1 - 60 minutes between start attempts
Programmable Outputs
Form C (DPDT), Rated 5 amps 240 VAC max, (1200 VA)

Programmable Ramp Types: Voltage or Current Ramp (VR or CR)
Starting Torque: 0 - 100% of line voltage (VR) or 0 - 600% of motor FLA (CR)
Ramp Time: 1 to 120 seconds
Current Limit: 200 - 500% (VR or CR)
4 Options: VR1+VR2; VR1+CR2; CR1+CR2; CR1+VR2
