  • Page 41 CAUTION Use Correct Wires and Terminations for Power Wiring in UL Installations. L1, L2,PE, R1 and R2 connections should be 14 AWG / 2.5 mm, 300V,105⁰C minimum. If ferrules are used with 14 AWG wire a precise crimp is required. The crimped ferrule must measure less than 2.1 mm on each side of the ferrule or it will not fit into the terminal opening.

  • Page 42: Power Connector Wiring

    Power Connector Wiring Refer to the following table for standard pre-wired power connector, part of Option “I”. WARNING Dangerous Voltages Present On Connector Pins #4 and #5 Pins #4 and #5 connect to terminals R1 and R2 for use with a braking resistor and have dangerous voltages present under normal operation and for up to 6 minutes after main power is disconnected.

  • Page 43: Brake / Shunt Resistor Considerations

    The user may override this protection to allow the actuator to move to a safe position before disabling or take similar immediate controlled action. Contact Exlar Application Engineering to enable this functionality. CAUTION Do not continue normal operation after reaching temperature or current limits.
  • Page 44 resistor assembly is best. Fuses are difficult to size properly; the intension on the fuse is not to protect the Tritex, but to protect the wiring and resistor from overheating. The resistor used must be rated for dynamic braking applications for 240 VAC drives, meaning it is capable of peak working voltage of at least 400V and can absorb high energy within a short period.

  • Page 45: Logic And Io Power Supply

    Logic and IO Power Supply The 75 mm Tritex contains a built in 24 Volt power supply, this supply can be used to power the optional internal brake as well as provide some power for the IO. The maximum current the internal 24 V can provide is 600 mA.

    Digital Inputs Tritex digital inputs are optically isolated from drive main power, but have a common negative side. SIO and Ethernet options have 8 inputs, the IA4 and CAN options have 4 inputs. They require a positive voltage to turn on, so are compatible with sourcing outputs only. The voltage for the input can be sourced from and external 24 V supply or from the internal 24V supply.

  • Page 60 4-20 mA Output The 4-20 mA output is a two wire circuit; it requires an external loop supply of 12 to 30V DC to generate the isolated supply voltages needed. The Tritex circuit requires 8V to operate; therefore the max impedance the output can drive is dependent on the loop supply voltage.

    The replacement battery kit is Exlar P/N 54108. The T2BAT1 kit (Exlar P/N 42712) for Tritex AC actuators will work, but outer sleeve on battery must be removed to fit well in clip.

    Important Note for units built before 2016: If the battery is removed with both Motor and Logic power also removed, do not reconnect the battery and leave all power off for 4 minutes. Once all power is removed from the battery backed logic it must be allowed enough time to completely bleed down before restarting.

    If your actuator has a preloaded roller screw, do not remove it from the cylinder. Preloaded screws require special tooling and procedures for proper disassembly and reassembly. Contact Exlar Corporation to arrange for maintenance of a preloaded screw actuator. Disassembly Refer to the exploded view on the following page.

  • Page 68: Grease Renewal

    Grease Renewal The angular contact thrust bearings located in the front of the actuator, the roller screw cylinder, and the roller screw assembly are the components that require grease. They require a coating of grease. They do not need to be packed with grease. Excess grease requires more torque from the motor when returned to operation, and does not improve the lubrication of the unit.

    2. Use a brush to work grease in to the roller screw assembly. Be sure to cover all the threaded surfaces of the screw assembly. This can be accomplished by applying grease to a few places on the roller screw assembly and rotating the components repeatedly in both directions to work the grease into the assembly.
  • Page 72 3. Carefully slide the face plate and bushing/seal assembly over the actuator rod end, while guiding the tie rods through the holes in the rear end cap of the actuator. The seal is a tight fit on the rod end. Take care not to damage the seal on the threads of the extending rod.
