Because of the variety of uses for the products described in this publication, those responsible for the application and use of this control equipment must satisfy themselves that all necessary steps have been taken to assure that each application and use meets all performance and safety requirements, including any applicable laws, regulations, codes and standards. [. . . ] (high frequency) Description The high frequency parameter sets the highest line frequency that the starter will operate on. When operating on line power, the default setting will usually suffice. If the application is speed sensitive, or the line power is suspect, the high frequency parameter can be set to the highest acceptable frequency. When operating on generator power, the high frequency parameter should be set to the highest acceptable frequency. This will ensure that a generator problem will not cause unnecessarily large fluctuations in the speed of the motor. The frequency must be above the high frequency setting for the frequency delay parameter before the starter will recognize a high frequency condition. Once a high frequency condition exists, the starter will shut down and display a fault 4, High Freq. Values Default The high frequency trip is adjustable from 72 to 24hz in 1hz increments. The default value for the high frequency trip parameter is 72hz. Low Freq. (low frequency) Description The low frequency parameter sets the lowest line frequency that the starter will operate on. When operating on line power, the default setting will usually suffice. If the application is speed sensitive, or the line power is suspect, the low frequency parameter can be set to the lowest acceptable frequency. When operating on generator power, the low frequency parameter should be set to the lowest acceptable frequency. This will ensure that a generator problem will not cause unnecessarily large fluctuations in the speed of the motor. The frequency must be below the low frequency setting for the frequency delay parameter before the starter will recognize a low frequency condition. Once a low frequency condition exists, the starter will shut down and display a fault 5, frequency < Low Freq. Values Default The low frequency trip is adjustable from 23 to 71hz in 1 Hz intervals. The default value for the low frequency trip parameter is 23hz. Freq Delay (frequency delay) Description The frequency delay parameter sets the time that the line frequency must go above the high frequency trip point or below the low frequency trip parameter before a high or low frequency fault will occur. The frequency delay parameter can be set from 0. 1 to 90. 0 seconds in 0. 1 second intervals. The default value for the frequency delay parameter is 0. 1 seconds. Values Default 67 5. 15 MOTOR PROTECTION - GROUND FAULT GND Fault (ground fault) Description The ground fault parameter sets a ground fault current trip or indicate level that can be used to protect the system from a ground fault condition. The starter monitors the instantaneous sum of the three line currents to detect the ground fault current. This is often referred to as residual ground fault protection. [. . . ] High isolation ring transformers are used to reduce the voltage down to 28 Vac for the sustained pulse firing circuit, providing further isolation for the SCR gates. Additional magnetic isolation is provided via a separate control power transformer (CPT), which powers the low voltage controls and the CPU.
