[. . . ] BENSHAW REDISTART DIGITAL RDB6 SERIES INSTRUCTION MANUAL Solid State Motor Control Technology Publication #: 890001-15-07 The Leader In QUICK START GUIDE Quick Start General This quickstart guide provides the information necessary for the operator to set the starter for basic operation. This manual should be read in its entirety before the starter is put into service. · Connect the incoming power connections to terminals L1, L2 and L3. · Connect the motor leads to T1, T2, and T3. · Connect the control wiring to TB1 on the control card, as shown in the following diagram. [. . . ] If the motor is still rotating when the deceleration time expires, increase the deceleration time. If the motor stops rotating before the deceleration time expires, decrease the deceleration time. NOTE: If the motor deceleration time parameter is set to OFF, the motor's deceleration is not controlled by the starter. If the motor needs to be stopped faster than the time it takes to coast to a stop, the deceleration control will not help. NOTE: P10 is not used in any of the controller modes. NOTE: If deceleration jumper JP1 is in place and deceleration time is programmed, the deceleration will not operate. The deceleration timer will block a restart attempt until it has timed out. This can operate as a blocked restart timer for up to 1 minute. This is useful for reversing starters or dual starters. Parameter Values The motor deceleration time parameter values range from OFF to 60 seconds. Parameter values are set in 1 second increments. The motor deceleration time parameter's default value is OFF. Parameter Default 25 4. OPERATING PARAMETERS 4. 12 Parameter Description P11 - Overcurrent Trip Level The overcurrent trip level parameter sets the high current level trip point as a percentage of motor full load amps parameter P1. The overcurrent trip level parameter takes effect after the motor is up to speed. This protection feature is also referred to as mechanical jam protection. NOTE: The overcurrent trip level parameter is not operational if the overcurrent trip time parameter (P12) is set of OFF. Parameter Values The overcurrent trip level parameter values range from 50% through 400%. Parameter values are set in 5% increments. The overcurrent trip level parameter's default value is 50%. Parameter Default 4. 13 Parameter Description P12 - Overcurrent Trip Time The overcurrent trip time parameter sets the length of time that the load current can continuously exceed the overcurrent trip level before a fault is generated. The overcurrent trip time parameter values range from OFF through 15 seconds. Parameter values are set in one second increments. axx indicates the fault will auto-restart after tripping in xx seconds. txx indicates the fault will require manual reset after tripping in xx seconds. Parameter Values Parameter Default Parameter Order The overcurrent trip time parameter's default value is OFF. t02 t01 4. 14 Parameter Description P13 - Undercurrent Trip Level The undercurrent trip level parameter sets the low current level trip point as a percentage of motor full load amps parameter (P1). [. . . ] An inside delta soft starter is shown in Figure 2, where the power poles are connected in series with the stator windings of a delta connected motor. The starter draws phase current (ia, ib, ic ). In a delta-connected motor, the average phase current is less than the average line current by a factor of 1. 73. By comparison of Figures 1 and 2, the most obvious advantage of the inside delta starter is the reduction of current seen by the soft starter. [. . . ]
