Display Description
Motor Load Curr.
90 % of FLC
Motor current as a percentage of Motor FLC.
Range: 0 - 1200% of Motor FLC.
Equivalent Curr.
90 % of FLC
Equivalent Motor current (increased by unbalance according to Unbalance K
Factor) as a percentage of Motor FLC.
Range: 0 - 1200% of Motor FLC.
Unbalance Curr.
0%
Unbalance current. The ration between Positive Sequence current to
Negative Sequence current. If Motor Load is less than 100% then the above
ration is multiplied by the factor (Motor Load / 100) to prevent nuisance
tripping
Thermal Capacity
30% of Capacity
Thermal Capacity used. Simulates motor’s winding temperature according to
the selected Thermal Overload Curve, to Unbalance Bias and to RTD Bias.
Trip Level = 100%
Time to Trip-O/L
No Trip Expected
Time to Start
0 Sec.
Expected time to trip at the present current value which is above Overload
Pickup.
Range: No Trip Expected - 18 Hours.
Expected time to start, displayed in one of the following cases:
• After "Thermal Trip". This is the expected time of the Thermal Capacity to
decay to 50% of the maximum "Thermal Capacity".
• After "Too Many Starts" Trip. In this case, maximum value of "Time to
Start" equals "Start Inhibit" Time.
Range After "Thermal Trip": 0 - 166 minutes
After "Too Many Starts" : 1 - 60 minutes
"Time to Trip" The expected time until motor trips. (i.e. the time to reach 100% of Thermal Capacity if
the present current value is maintained). This value is calculated and displayed on the LCD. The host
computer may read this value through the serial link, and try to take some corrective actions.
"Time to Start" The expected time until it is possible to re-start after Thermal Trip (i.e. the time to
reach 50% of Thermal Capacity) or after Too Many Starts. This value is calculated and displayed on
the LCD.
Reset of the Thermal Capacity
If Emergency Restart switch is closed, then Thermal Capacity is automatically reset when motor is
stopped, to allow immediate restart of a hot motor.
