Operation EN EP5PTI19 HR10-MT

■

≤10 seconds for tools up to 850Nm

If the target torque is achieved with less than 5 pulses (= short tightening time), the torque scatter will in-

crease and it can be difficult to adjust to the right level, especially on hard joints.

If the target torque is achieved with more than 20 pulses (= too long tightening time) the wear will in-

crease and more frequent oil filling and service will be required. Too long tightening time, in combination

with high production rate, may also result in excessive heating of the oil. In that case the power will de-

crease with longer tightening time and sometimes no shut off.

If the target torque is achieved with less than 5 pulses this can be fixed by:

■

Decreasing the air pressure.

■

Reducing the speed by means of the AutoTrim or Trim valve.

■

If the above is not possible or does not give wanted results, a smaller tool may be a better choice.

If the target torque is achieved with more than 20 pulses this can be fixed by:

■

Increasing the dynamic air pressure to 6-7 bar for standard EP tools, or up to 5 bar for low pressure

EP L-tools.

■

Adjust the AutoTrim or Trim valve to give maximum power/speed.

■

If the above is not possible or does not give wanted results, a bigger tool may be a better choice.

When changing the air pressure, the target torque must be measured again and adjusted if needed.

MultiTrim function/feature

All PTI tools are initially launched and delivered with Trim-function only. The AutoTrim function is still

under development and will be launched when it is optimized even further.

The design of PTI-MT tools combines the advantage of both AutoTrim and Trim function - MultiTrim - in

the same tool. The tools are factory set at AutoTrim function and can easily be change to Trim function

when suitable for the application.

When to use AutoTrim valve or Trim valve

Use AutoTrim valve:

■

For applications where the tool is used to tighten both hard and soft joints.

Use Trim valve:

■

For applications where the tool is used for tightening joints with similar characteristics.

Position of the set screw with AutoTrim or Trim setting:

function or Switching to AutoTrim function.
