Troubleshooting:
Malfunction
Tool does not start
No acoustic signal after connection
of tool cable
Tool doesn't start with
counterclockwise rotation activated
Tool starts in tightening direction, but
not in counterclockwise rotation
Tool shuts off at desired torque but
without angle indicator
Tool shuts off prematurely
Tool does not change speed
LEDs on the tool start to flash when
the reverse switch is operated
Warning in RUN SCREEN: Offset
Transducer 1/2 NOK
Warning in RUN SCREEN: Tool
Offline!
Different torque display in the control
and external transducer
Tool cable does not fit in tool handle
EN
Possible causes
Faulty start switch
No speed (RPM) programmed
Controller waiting for tool enablement
Faulty cable
Bent pins in cable or tool
Self identification data not recognized
after tool change
Software incorrect
Cable defective
Tool defective
With counterclockwise rotation,
parameter for speed is set to 0 rpm.
No speed programmed for
counterclockwise rotation
Faulty reverse switch
Faulty cable
Bent pins in cable or tool
Threshold torque is too high
Operator releases start switch before
the control stops the tool
The fastening time exceeds the
standard time by 10 seconds.
Tool exceeds the angle setpoint
Speed is the same in all stages
This is a normal function which is
defined in the default parameters.
The transducer does not return to a
zero torque value.
Faulty wiring in tool or cable
Tool has not been accepted in the
Tool Settings
A faulty cable will prevent the tool
from being recognized by the
nutrunner control.
Torque calibration factor (Torque
Cal.) in Tool Settings must be
adjusted.
Customer's angle attachment was
added to tool. Tool memory must be
updated.
Wrong Cable. Tools in use with
nutrunner control mPro400GC use
an Air-LB connector. Connector has
different size to previously used
Matrix connector.

Remedy
! Replace start switch
! Program speed for all active stages
Activate input Tool Enable or, if not required
!
Deactivate Tool Enable
!
! Repair or replace cable
! Straighten contact pins or replace faulty connector
! Accept Data again (Tool Setup)
Check controller software / measuring board
!
software
! Replace cable
! Change tool
! Program speed for counterclockwise rotation
! Program speed for counterclockwise rotation
! Replace Start/Reverse switch assembly
! Repair or replace cable
! Straighten contact pins or replace faulty connector
Correct fastening sequence or reduce threshold
!
torque value
Make sure that the operator keeps the start switch
!
pressed throughout the entire sequence.
! Increase the fastening time
Check the fastening sequence to ensure that the
!
torque shutoff value and/or angle setpoint are
correct. Adjust as necessary.
Check whether the fastening joint has changed
!
significantly.
Make sure that the speed and the switching angle in
!
the stages are correct.
Activate or deactivate the check box Blink Lights
!
when Tool in Reverse
Transducer has been overloaded and must be
!
replaced
Check tool with different cable. The offset and
calibration values can be checked in the Diagnosis
!
menu.
Check the Tool List menu to make sure that the tool
has been accepted. If it has not been accepted, the
status will show Manual acceptance needed. The
!
correct line must be marked before the setting can
be accepted in the Tool Settings menu.
! Repair or replace cable
Adjust Torque Cal. (Tool Settings) using the
following formula:
!
New calibration value = (external value / tool value)
x calibration value used
! Reprogram tool memory
! Use the right cable for the tool being used.
