Service instructions
Pressure level 2 (P2) starts a timer that checks the time taken from when the
clutch has been released to when the operator releases the trigger to ensure that
it is not too short.
The controller measures the differential pressure over the motor.
It should be noted that the system does not measure torque! Regular check of
installed torque/torque output of the tool must be done separately.
The RE-Controller checks the air-line pressure. One of the most common prob-
lems in air-line systems is pressure variations. If the pressure drops too much
the tool might stall and/or the torque will not be correct. The RE-Controller will
give a signal if the pressure drops too much.
The RE-Controller alerts the operator when it detects:
• Missed fasteners
• Premature tool shut-off
• Stripped threads
• Cross-threading
• Rehits
• Drop in air supply
The air pressure inside the tool is measured through a small hose (see Optional
accessories - Kit RE-Signal) and converted into a digital signal. This signal is
processed in the RE-Controller. The RE-Controller gives instant visual and au-
dio feedback to the operator on whether the tightening was OK or not OK.
