| Event Timer Control |
24 hr, 7 day, 7 event timer allows automatic start w/ batch run time control |
| Batch Run Timer Control |
Minimum run timer (resumes timing if stopped) or permissive run timer (only runs during set time). Time setting: 1 - 9999 minutes. |
| Protection |
| Overload Protection Method |
Real-time Motor Thermal Modeling uses current sensors and microprocessor to continuously calculate motor
temperature |
| Retentive Thermal Memory |
Remembers the thermal condition of the motor even if control power is lost. Thermal register is adjusted for
Off-time
when power is restored. |
| Dual Overload Curve Settings |
Two separately programmable overload trip curves; one for starting and one for running. OL trip range: Class 5 -
30. |
| Learned Dynamic Reset |
Automatically adjusts other settings to compensate for programmed Service Factory. Adjustment Range: 1.0 - 1.15
SF. |
| Programmable Service Factor |
Automatically adjusts other settings to compensate for programmed Service Factory. Adjustment Range: 1.0 - 1.15
SF. |
| Current Imbalance Protection |
Monitors phase-to-phase current levels and trips if imbalance exceeds setting. Setting: Off or 5 - 30% of FLA
with 1-20
second delay. |
| Phase Loss / Sequence Protection |
Trips if any phase < 20% FLA. Sequence selectable A-B-C, C-A-B or Off. |
| Current Trip |
Over Current: Electronic shear-pin/shock relay. Off or 50-300% FLA, 1-20sec delay
Under Current: Load-loss/loss of prime. Setting: Off or 10-90% FLA, 1-60sec delay |
| Over Voltage Trip (any phase) |
Setting: Off or 1-10% of set voltage with 1-20 second delay |
| Under Voltage Trip |
On Startup: Setting: Off or 1 - 20% of set voltage with 1-120 second startup time
At Full Speed: Setting: Off or 1 - 20% of set voltage with 1-20 second trip delay
|
| Load Monitor |
Under or over kW trip or alarm. Setting: Off or 20 - 100% of motor kW with 1-20sec delay |
| Power Factor Monitor |
Leading or lagging PF, trip or alarm. Setting: Off or 0.1 - 1.0PF (lead or lag) with 1-20 second delay |
| Frequency Monitor |
Over or under programmed frequency. Setting: Off or 1-10Hz with 1-20sec delay |
| Equipment Ground Fault Protection |
Electronic residual current protection method, no additional CTs needed. Setting: Off or 5-90% of CT with
1-60sec delay |
| Short Circuit / Shorted Load |
Peak current quick trip (electronic fuse). Trip level: Off or 800-1400% FLA with 0.1 - 0.5sec delay |
| Restart Delay Timer |
Programmable delay of restart after a power failure. Setting: 0 - 999 sec. |
| Starts-per-Hour Lockout |
Program maximum starts-per-hour in adherence with motor design limitations. Setting: Off or 0 - 10 starts/Hr.
|
| Minimum Time between Starts |
Used with or without starts-per-hour protection to prevent short cycling of motor. Setting: Off or 1 - 60
minutes
between starts |
