TX Series 48 - 1250A Chapter 1 - Introduction This chapter is a brief introduction to the TX Series soft starter and describes product operation and unit features. 1.1 - General The TX Series is a high-end digitally programmable solid state reduced voltage soft starter. This heavy duty starter provides reduced voltage, stepless soft starting of 3-phase AC induction motors, protecting mechanical components from excessive torque stress and electrical systems from the effects of high motor inrush currents.
TX Series 48 - 1250A 1.2 Specifications (continued) Advanced Motor Protection Two Stage Electronic Overload Curves Starting: programmable for Class 5 - 30 or locked rotor time. Run: Programmable for Class 5 - 30 when "At-Speed" is detected. Overload Reset Manual (default) or automatic Retentive Thermal Memory Overload circuit retains thermal condition of the motor regardless of control power status. Unit uses real time clock to adjust for off time.
TX Series 48 - 1250A 1.
TX Series 48 - 1250A 1.3 - Theory of Operation The power of the TX Series is in the CPU, a microprocessor based protection and control system for the motor and starter assembly. The CPU uses Phase Angle Firing of the SCRs to apply a reduced voltage to the motor, and then slowly and gently increases torque through control of the voltage and current until the motor accelerates to full speed.
TX Series 48 - 1250A Other starting methods available in the TX Series are: · Current Ramp: uses a closed current feedback PID loop to provide a linear torque increase up to a Maximum Current level. · Constant Current: current is immediately increased to the Current Limit point and held there until the motor reaches full speed. · Custom Curve: gives the user the ability to plot torque and time points on a graph. The soft starter will then accelerate the motor following these points.
TX Series 48 - 1250A Run Mode: The soft starter enters the Run Mode when it reaches full output voltage and the motor current drops below the FLA setting (motor nameplate FLA plus service factor) for a predetermined period of time.
TX Series 48 - 1250A Run Mode overload protection is initiated when the TX Series determines that the motor is At-Speed. Overload Protection is initiated when the motor RMS current rises above a “pick-up point” (as determined by the motor nameplate FLA and service factor). Run mode protection is provided by the CPU monitoring the Dynamic Thermal Register. Data for the Dynamic Thermal Register is accumulated from I2t calculations and cooling rates.
TX Series 48 - 1250A Chapter 2 - Installation 2.1 Receiving and Unpacking Upon receipt of the unit: • Carefully unpack the unit and inspect it for any shipping damage. Report any damage immediately and file a claim with the freight carrier within 15 days of receipt. • Verify that the model number on your unit matches your purchase order. • Confirm that the ratings label on the unit matches or is greater than the motor’s HP and current rating. 2.
TX Series 48 - 1250A Remove all sources of power before cleaning the unit! WARNING In dirty or contaminated atmospheres the unit should be cleaned on a regular basis to ensure proper cooling. Do not use any chemicals to clean the unit. To remove surface dust use 80 to 100 psi, clean, dry compressed air only. A three inch, high quality, dry paint brush is helpful to loosen up the dust prior to using compressed air on the unit. 2.
TX Series 48 - 1250A 2.7 Power Connections Connect appropriate power lines to the unit input terminals marked L1, L2, L3. Avoid routing power wires near the control board. Connect the motor leads to the unit terminals marked T1, T2, T3. Refer to NEC standards for wire length and sizing. Never interchange input and output connections to the unit. This could cause excessive voltage in the control logic circuit and may damage the unit.
TX Series 48 - 1250A 2.8.2 Two-Wire Connection An alternate connection for unattended operation replaces start/stop push buttons by connecting a maintained contact closure between pins 3 and 5 on TB4. When the maintained contact is used for start/stop it is necessary to set the overload setpoint to the manual reset position. This will prevent the motor from restarting if the thermal overload trips and then cools off.
TX Series 48 - 1250A 2.8.4 Power Board 2.8.
TX Series 48 - 1250A 2.9 CPU Board Connections There are eight digital inputs on the CPU board. Four of the inputs are user programmable. There are also two analog outputs, a tachometer feedback input. 20 20 1 2 + - 3 4 5 + - 6 7 8 + - 1 2 3 4 + - 5 6 7 8 Note: Install program jumper to enable setpoint programming.

TX Series 48 - 1250A Chapter 3 - Start-up WARNING THE TX UNIT DEALS WITH POTENTIALLY LETHAL VOLTAGE LEVELS. YOU MUST BE CERTAIN THAT PERSONNEL ARE THOROUGHLY TRAINED IN THE APPLICABLE SAFETY PRECAUTIONS BEFORE PROCEEDING WITH THIS SECTION! 3.1 Preliminary Start-Up Check List Please make the following checks before applying power to the unit: • Supply voltage matches the rated supply voltage of the unit. • Horsepower and current ratings of the motor and unit match or the unit has a higher rating.
TX Series 48 - 1250A The current limit must be set high enough to allow the motor to reach full speed. The factory setting of 350% is a good starting point. Do not set the current limit too low on variable starting loads. This could cause the motor to stall and eventually cause the overload protection to trip. 3.4 Deceleration Adjustments (Pump Control) Decel extends the stopping time on loads that would otherwise stop too quickly if allowed to coast to stop.
TX Series 48 - 1250A Another common application for decel control is on material handling conveyors as a means to prevent sudden stops that may cause products to fall over or to bump into one another. In overhead crane applications, soft stopping of the Bridge or Trolley can prevent loads from beginning to over swing on sudden stops. 3.4.
TX Series 48 - 1250A 3.5 Sequence of Normal Operation • • • • • • Apply control power and check that the “Power” LED comes on. (Display 1) Apply three phase power to the unit. The motor should run only when the start command is applied. Apply the start command. (Display 2). The RUN LED will be lit. (Display 3) The AUX3 LEDs will be lit. If the motor does not enter run mode in the set time, a trip will occur. The POWER, RUN, AUX3 LEDs will be lit, indicating that the contact has energized.
