Smart Engagement Step

Smart engagement is used to facilitate screw engagement, normally at low RPM (100-150 rpm). Smart engagement first reaches an engagement torque and then has to stay below Max. torque and over the engagement torque during a set validation angle. By monitoring the torque during the validation angle and the tightening step angle, the step can instantly detect tilted and missing screws.
When reaching the set engagement torque a possible engagement is triggered. After reaching the engagement torque the controller will monitor the torque for a set validation angle to make sure that the screw is correctly engaged. If the tightening reaches max. torque or max. angle a retry action is triggered. A retry action can either consists of a retry or an abort. The user can define how the tightening should act according to the different errors. If the retry action is triggered due to max. torque it is most likely caused by a tilted screw and therefor retry is advised as a retry action.
If the retry action is triggered due to max. angle it is likely that the error was triggered by a missing screw and therefor abort is advised as a retry action.

Speed	The tool speed is programmable within the valid range.
Engagement torque (A)	Activates validation angle after reaching the engagement torque.
Validation angle (C)	Monitors the torque for a specified angle to make sure that the torque is above the engagement torque and below the max torque. Step is completed when these requirements are fulfilled.
Retry action	None – Aborts tightening All – Triggers a retry if max torque or max angle is reached Torque high – Triggers a retry if max torque is reached Angle high – Triggers a retry if Max. angle is reached
Loosening angle method	Auto – Automatically calculates optimal loosening angle from current tightening User defined – User defined loosening angle.
Loosening angle	User defined angle used for retries.
Loosening torque	Max. torque while loosening.
Loosening speed	The speed set for loosening if a retry has been triggered.
Direction	Direction of the tightening, clockwise or counterclockwise. Use clockwise setting for normal tightening
Retry Signal	Defines what Externally Monitored Input should activate if the tool is currently loosening during a retry.
Vacuum enabled	Digital output to switch on an external vacuum pump.
Fast speed change	Makes it possible to shift fast between fast and slow speed. When enabled it will be possible to get a more accurate torque estimation for current controlled tools over a longer time frame. This applies in the transition of the current step and the next step.
Max. torque (B)	If max torque is reached a retry action will be triggered.
Max. angle (D)	If max angle is reached a retry action will be triggered.
Retry limit	Number of times the tightening will try to retighten the screw after a retry action has been met.
Step start delay	Delay from trigger to tool start.
Min. step time	Minimum time for the step. If not reached, the controller will display an error message
Max. step time	Maximum time for the step. If exceeded, the controller will display an error message.
