- Tools with RE-L at the end of the model number are TRIM – RE (manual trim low pressure) Example EP5TX10 HR42-RE-L
- Tools with AT-L the end of the model number are TRIM – RE (auto trim low pressure) Example EP5TX HR10-AT-L
Atlas Copco shut-off pulse tools shut off the air supply when the pre-set torque is been reached. Operator influence is minimized and the result is increased accuracy and faster tightening.
Torque sensing system – In ErgoPulse PTS and PTX nutrunners torque is “sensed” by means of a rotatable inertial mass acting against an adjustable spring. The result is a highly accurate and easily adjustable shut-off system.
Pulse mechanism – The pulse mechanism has pistons for minimum weight and long service life. The design is based on cam-guided pistons and rollers and the pulse cylinder is oil-filled. The moving parts are thus completely immersed in oil, which ensures a long service life.
AUTOTRIM valve – PTS/PTX-AT tools are equipped with an automatic twostage trim valve. The tool runs down the screw with reduced free speed. After 1-2 pulses it shifts automatically to full power thus enabling both hard and soft joints to be tightened with excellent results without any adjustments. The PTS/PTX tools can also be used for reporting applications
