2. Do not use the power tool if the switch does not turn it on and Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
3. This product is designed to be used in combination with the AcraDyne iEC DC tool controller for intermittent hand-held or fixtured assembly

Operation

Connect tool cable to the iEC controller and the tool: AcraDyne recommends not exceeding 20m length of The tool cable has curved alignment tabs and slots built into the connectors at each end to ensure proper alignment and connection with the tool and controller.
Make sure that power is not turned on at the controller before making any connections. Align the female connector on the cable with the male connector on the tool and insert the cable onto the tool, then slide the connector nut onto the threads on the cable and turn clockwise until hand- tight.

Align the male connector tab on the other end of the tool cable with the female slot on the controller and insert the cable into the connector, then slide the metal outer cover onto the connection threads on the controller and turn clockwise until hand-tight.

Multifunction Button Operation:

The tool will flash all LED lights three times when power is first turned on at the controller. After the controller finishes initializing and displays a target toque value, the multifunction button (MFB) is used to toggle the tool from clockwise mode (FWD) to counter-clockwise operation mode (REV). The MFB is the small button opposite the trigger.
The tool will initially start in clockwise mode and will have no LED lights turned on. If the trigger is pressed, the tool will turn on the blue LED meaning the tightening operation is underway. Pressing the MFB will cause the tool to flash yellow and red LED lights. Pressing the MFB again will switch the tool back FWD mode and will indicate this with no LED lights turned on.
AEF fixtured models are not equipped with a multifunction button. Tool operation is handled by the IO of the Gen IV iEC controller.

Start Trigger Operation:

To start the tool, depress the start trigger. Blue LED lights will be displayed while tightening a bolt. The tool will stop automatically when it senses its target torque value or if no torque is sensed in a specified time period. After a cycle is complete, the tool will display green LED lights for a success, or red LED lights for failure to reach torque/angle.
AEF fixtured models are not equipped with a start trigger. Tool operation is handled by the IO of the Gen IV iEC controller.

LED Light Assignment

The Buzzer and Multi-Function Button are programmable in the DSP Menu of ToolWare.

Tubenut Tool Setup

The following describes the setup required for tube-nut tool operation. This includes determining the values for tube- nut specific TID parameters (parameters residing in the tool memory) and iEC Controller parameters.

Tube Nut Homing

Tube Nut Homing Start Input Logic Selection:

The controller parameters for tube- operation can be viewed and modified from the Controller->Edit Controller Parameter->Tube Nut screen in ToolWare.

• Tube nut Home Strategy:
  • Lever action required to start the home
  • Options:
  • Home on release and repress of the lever (default)
  • Home on release of the lever

Tube Nut Home TID parameters

The tube nut TID parameters can be viewed and modified from the Tool-> Edit->Tool Setup screen in ToolWare. The tool to be configured must be connected to the controller.
Home Detection Torque – Home (in*Lb)

• When the tool is homing, reaching this torque indicates to the controller the tool output socket has reached the home stop and is in the open
• If the tool output does not attempt to return or does not completely reach the home position, this value is too
• Attention: Setting this value too high can potentially damage the
• Units: lbf-in
• TID memory location: 53

Hold at Home Torque – Open Loop (in*Lb)
After reaching the home position, this torque is applied against the home stop to prevent the socket from bouncing to a partially closed position.

• This value is typically set to a value slightly lower than the home detection
• If the socket bounces back to a partially closed position after reaching the home stop, this value is too
• Attention: Setting this value too high can cause the socket to snap back to the home stop too quickly and potentially damage the
• Units: lbf-in (approximation)
• TID memory location: 54

Typical Procedure for Setting the Tool’s Tube Nut Home TID Parameters

• Set the Hold at Home Torque = 0
• Set the Home Detection Torque = 1
• Free run the tool and watch the homing routine while making the adjustments below
• Gradually increase the value for the Home Detection Torque until the tool reliably returns to the home position
• Once a good value for the Home Detection Torque is found, if the tool is bouncing back to a partially closed position after hitting the home stop
• Gradually increase the value for the Hold at Home Torque until bounce back is eliminated

Tube Nut Obstruction Detection

Tube Nut Home TID Parameters

The tube nut TID parameters can be viewed and modified from the Tool-> Edit->Tool Setup screen in ToolWare. The tool to be configured must be connected to the controller.

• Obstruction Detection Torque – (in*Lb)
  • At the start of rundown before the output rotation has passed though the Obstruction Check Zone (where the output is open at the start of the fasting cycle), the tool will stop and fastening cycle will be aborted if this torque is
  • If the tool stops, when the output is open during this first part of the rundown, without any obstruction, the value is too
  • Units: lbf-in
  • TID memory location: 53

Typical Procedure for Setting the Tool’s Tube Nut Obstruction Detection

Parameters

• Set the value for the obstruction torque just high enough so the tool will reliably overcome gear friction and make it past the obstruction checking
• Check the torque of the stop on obstruction feature by measuring the actual “obstruction” torque the tube nut produces at the start of the rundown when the jaws are open (within the obstruction detection angle range). This can be done on a semi-tightened joint simulator set for a hard joint, while auditing the
