If there is more than one motor connected, the motor FLA should be set to the sum of the connected motor full load amps. NOTE: The starter uses the entered motor FLA for every current based calculation. [. . . ] The current must be below this parameter setting for the no current at run delay time before a fault will occur. Motor Protection/Line Current/No Current @ Run Delay (Min 0. 1s, Max 90. 0s, Default 1. 0s) The no current at run delay parameter sets the time that the motor current must be less than the percent no current at run parameter setting, while the starter is in a run state, before a trip will occur. Page 15 of 36 Redi-Start MicroII Redi-View Dictionary Motor Protection/Line Voltages Motor Protection/Line Voltage/H&L Voltage Level (Min 10%, Max 30%, Default 20%) The high/low voltage trip sets the allowable operating voltage range. If the voltage on any line goes outside of the allowable operating range, the starter will shut down and give a high or low line fault. The low and high voltage trip points are calculated as follows; LV <1000 VAC The base voltage (Vbase) that is used for the calculations is either set by the source voltage parameter (see page 5) or automatically selected according to the following list; 208VAC if average line voltage is between 180VAC and 224VAC. 240VAC if average line voltage is between 225VAC and 269VAC. 315VAC if average line voltage is between 270VAC and 334VAC. 380VAC if average line voltage is between 345VAC and 409VAC. 460VAC if average line voltage is between 410VAC and 489VAC. 480VAC if average line voltage is between 490VAC and 524VAC. 575VAC if average line voltage is between 525VAC and 650VAC. 1000VAC if average line voltage is between 651VAC and 1000VAC. MV >1000 VAC The base voltage (Vbase) used for the calculations is selected by setting jumpers JPC17 and JPC18 on the RediStart Micro computer card. The line voltage must be out of the specified range for the time specified by the delay time parameter before the starter will trip. Caution: Contact factory prior to changing this jumper. Motor Protection/Line Voltage/Delay Time (Min 0. 1s, Max 3. 0s, Default 0. 5s) The delay time parameter sets the time that the line voltage must go outside of the voltage range set by the high/low voltage parameter before a high or low voltage trip will occur. This parameter may be lengthened to allow for temporary voltage fluctuations outside of the allowable voltage range. If the time is extended, the control voltage must be monitored to ensure it remains within acceptable limits. If the control voltage is fluctuating, an un-interruptible power supply should be used. Page 16 of 36 Redi-Start MicroII Redi-View Dictionary Motor Protection/Line Frequency Motor Protection/Line Frequency/High Frequency (Min 24, Max 72, Default 72) 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, frequency > high fault. Motor Protection/Line Frequency/Low Frequency (Min 23, Max 71, Default 23) The low frequency parameter sets the lowest line frequency that the starter will operate on. [. . . ] The part number is of the form BICTxxx1M, where xxx is the CT primary and the 1 indicates the normalized 1 amp secondary. The CT ratio can be set to following values; · 100 (:1 or 20:0. 2) · 288 (:1 or 58:0. 2) · 720 (:1 or 144:0. 2) · 864 (:1 or 173:0. 2)) · 1000 (:1 or 200:0. 2)) · 2640 (:1 or 528:0. 2) · 2880 (:1 or 576:0. 2) · 3900 (:1 or 780:0. 2)) · 5000 (:1 or 1000:0. 2) · 5760 (:1 or 1152:0. 2) Factory Setup/Hardware Setup/Relay Card (See Below) The relay card parameter should be set to reflect the optionally installed relay card. The relay card can be set to; · None - no relay card installed · OUT4- four relay output card installed · OUT7- seven relay output card installed Page 32 of 36 Redi-Start MicroII Redi-View Dictionary RTD Setup/RTD Module Setup RTD Setup/RTD Module Setup/Module#1 Address (Min 16, Max 23, Default 16) The module #1 address parameter has to be set to the MODBUS address of the first RTD module attached to the soft-starter. The address of the RTD module can be verified by checking the rotary switch on the top of the RTD module. RTD Setup/RTD Module Setup/Module#2 Address (Min 16, Max 23, Default 17) The module #2 address parameter has to be set to the MODBUS address of the second RTD module attached to the soft-starter.
