Do not make any modifications to the controller, pro-
tective devices, or accessories without prior written
authorization from Apex Tool Group.
Do not attempt to open the controller or components of
the controller for troubleshooting or other work on the
device. In the event of a fault, any intervention can
result in serious injury from electric shock.
Operation with the device open may also cause the fol-
lowing:
-
An increased amount of emissions: may produce
interference with other devices.
-
Reduced immunity from interference: may produce
faulty results.
-
Loss of remaining warranty period.
Risk Of Injury Due To Electric Shock
The controller and tool can conduct current in the event of
a fault. An electric shock can lead to cardiac arrest, cessa-
tion of breathing, burns, and serious or fatal injuries.
Always turn off the controller before connecting power
and tool cables, cleaning or removal from operation.
Do not operate the tightening system if the housing,
cable or tool are damaged.
Installation
Use an approved hoist to raise controller to desired
installation location.
Ensure the controller is rigidly mounted and
secured(see Quick Installation Guide).
Organize cables and lines to avoid damage and trip-
ping hazards.
Observe the permitted cable bending radius.
In the event of a fault, high leakage currents may occur and
cause injuries by electric shock.
Use an approved power cable, with suitable ratings.
Prior To Initial Operation
Only operate on a grounded power supply with a neu-
tral conductor (TN system). Operation without a neu-
tral conductoron (IT system) is not permitted.
Ensure a standard-compliant PE connection is in
place.
A ground fault circuit interrupter (GFCI) type A is rec-
ommended to protect the supply line.
Prior to initial operation, carry out the protective con-
ductor measurement in accordance with the local reg-
ulations (in Germany, DGUV Regulation 3).
Do not switch on the controller until all connections
have been made correctly.
Operation
Protect the controller from moisture.
Immediately power off the controller in the event of
unusual noise, heating or vibration from the tool.
Disconnect the power cord and have the tightening
system checked by qualified personnel and repaired if
necessary.
Never pull the power cord to remove from an outlet.
Protect all cables from heat, oil, sharp edges and mov-
ing parts.

Replace damaged cables immediately.
Ensure tool and plug connections between the
controller and tool are clean.
Ensure the workstation and surrounding area are
clean.
Ensure the workstation provides adequate space for
the operation being completed.
When working with a nutrunner, remain alert at all
times. Do not use a nutrunner if you are tired or under
the influence of drugs, alcohol or medication. A
moment of carelessness when working with a nutrun-
may contribute to a life threatening situation.

Danger Due To Incorrect Torque Measurement
An undetected NOK tightening may contribute to a life-
threatening situation.
Recalibration (or capability analysis) is essential fol-
lowing incorrect use (crash, mechanical overload...).
For Category A Tightenings (VDI 2862) which are criti-
cal for safety, activate a redundancy measurement
(e.g., current redundancy).
Introduce regular monitoring of measuring equipment
for associated manufacturing equipment.
Only conduct tightening operations with a properly
functioning system. If in doubt, contact Sales & Service
Centers.
Danger Due To Unexpected Start Of The Motor Or An
Expected But Missing Stop
Despite redundant controller parts and monitoring func-
tions, an unexpected start of the machine can occur in very
rare cases. Possible reasons may include, but are not lim-
ited to: Remote control of diagnostic functions, bit dump in
the memory of the controller.
Mechanical hazards such as jars/jolts due to counter
torques; risk of injury due to winding up and seizing can
result from the tool.
Use the tool at the designated grip points.
Use the recommended reaction devices. For torques,
reference appropriate tool instruction manual.
After powering the controller on, wait until the boot
cycle is completed, approximately 60 seconds, before
powering it down again.
Use of Secondary controllers
Up to 15 Secondary Controllers can be added to a Primary
Controller. Upon shutting off or in case of a Secondary
Controller failure, the TSNet bus communication is inter-
rupted. The communication loss to the Primary Controller
has consequences for a Secondary Controller:
→ No results are returned to the Primary Controller.
→ Additional rundowns are not initiated.
→ An in-process rundown is reported with the error
message SA (abort by removing the start signal) if
the TSNet connection is interrupted during tighten-
ing.
→ A shut-off signal is no longer received and so a
shut-off is only possible
-
via the start button of the tool
-
after reaching the shut-off criterion
-
via a safety shut-off after two seconds
