[. . . ] Once the starter recognizes a ground fault condition, it will shut down the motor and display a fault 71-Ground Fault. If a programmable relay is set to ground fault (GND), the starter will energize the relay when the condition exists. If it is desired to have the starter continue to operate after a ground fault is detected, enter the fault classes menu (see page 52) and change the classification of fault 71 to either Dis, WrnA, WrnB, or WrnC. A typical value for the ground fault current setting is 10% to 20% of the full load amps of the motor. Values The ground fault is adjustable from 1 to 100 amps in 1 amp increments. The ground fault current can also be set to Off by setting it below 1 amp. The default value for the ground fault parameter is Off. Default GND Delay (ground delay) Description The ground delay parameter sets the period of time that the ground fault current must be above the ground fault current setting before a ground fault trip will occur. The ground delay parameter can be set from 0. 1 to 90. 0 seconds in 0. 1 second intervals. The default value for the ground delay parameter is 1. 0 seconds. Values Default 45 5. 9 PROGRAMMING: Motor Protection - Over Current Current Description The current parameter is set as a percentage of the motor FLA parameter. It sets a high current trip or indicate level that can be used to protect the system from an overloaded condition. The motor current has to remain above the current setting for the delay time parameter before the starter will recognize an over current condition. NOTE: This test is only when the starter is in an up to speed (UTS) state. The default value for the current parameter is Off. Default Detect Dly (detect delay) Description The detect delay time parameter sets the period of time that the motor current must be greater than the over current level before a shear pin trip will occur. The detect delay time can be set from 0. 1 to 90. 0 seconds in 0. 1 second intervals. The default value for the detect delay time parameter is 0. 1 second. Values Default Release Dl (release delay) General The release delay time sets how long the relay is energized after the over current condition is cleared. This parameter is only functional if a relay has been programmed to OCT (over current trip) in the relay sub-menu (see page 55) and the fault has been disabled in the fault classes sub-menu (see page 52). The release delay time parameter can be set from 1. 0 to 90. 0 seconds in 0. 1 second intervals The default value for the release delay time parameter is 10. 0 seconds. Values Default 46 5. 10 PROGRAMMING: Motor Protection - Under Current Current Description The current parameter is set as a percentage of the motor FLA parameter. It sets a low current trip or indicate level and can be used to protect the system from an unloaded condition. The motor current will fall when the pump becomes unloaded and the under current protection can be used to shut down the motor or warn of this unloaded condition. The motor current has to remain below the under current setting for the under current delay time parameter before the starter will recognize an under current condition. NOTE: This test is only when the starter is in an up to speed (UTS) state. The current can also be set to Off by going below 10% The default value for the current parameter is Off. Default Detect Dly (detect delay) Description The detect delay time parameter sets the period of time that the motor current must be less than the current level before an under current trip will occur.
