EN 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-
ner 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
WARNING!

Apex Tool Group P2552HW | 2021-04 9
1
EN
During remote-start operation (multiple tool setup) an inter-
ruption of TSNet bus leads to a delayed stop of the spindle/
tool. This delay is 2 seconds.
Maintenance
The controller is generally maintenance-free.
Consider local regulations for maintenance and servic-
ing for all operating phases of the tightening system.
Cleaning
Only clean the exterior of the tool using a dry or slightly
damp cloth.
Do not immerse the controller or tools in any liquids.
Do not use a high pressure or abrasive cleaner.
Disinfection of surfaces with alcohol-based disinfectant
is permitted.
Repair
Repairs to the equipment are not permitted.
Send the controller to a Authorized
Cleco Production Tools Sales & Service Centers.
Disposal
Components of the tightening system may present poten-
tial risks the environment. The tightening system contains
components that can be recycled, as well as components
that have specific disposal requirements.
Follow local applicable regulations.
First separate, then dispose of components.
Collect auxiliary materials (oils, greases) and dispose
properly.
Separate the components of the packaging and dis-
pose of them according to local regulations.
Return defective equipment to an approved collection
point or return it to the Sales & Service Centers.
Observe local regulations for disposal of
electronics and batteries. (In Germany,
the Electrical and Electronic Equipment
Act (ElektroG) and the Battery Act
(BattG)):
Used up batteries must be disposed
of properly. Return depleted or defec-
tive batteries to an approved collec-
tion facility or to Sales & Service
Centers for recycling.

The controller is primarily used as a control and monitoring
unit for one or more tools at a workstation. Depending on
the peripheral devices that are procured, the controller can
also be installed outside of the work environment.
Software is already installed on the controller. The tighten-
ing settings must be carried out by a qualified person using
the controller or remote PC software (mProRemote) in
order to start fastening work. For further information
regarding software operation, please reference the Pro-
gramming Manual.
Nutrunner controllers with the suffix STO in the type name
are equipped with the STO safety function, see Chapter 9

EN 9 STO safety function
9.1 Definition
The STO safety function enables the controller mPro300GCD-STO to provide a reliable solution for switching off the
energy supply at the output of the built-in nutrunner.
If several mPro300GCD-STO units are wired in series with STO connector cables, the STO function is guaranteed for the
complete group.
STO = Safe Torque Off. For the currently observed standards, please refer to 4Technical Specifications.
9.2 Performance features
• Reaching the STO safety function
• Potential-free feedback contact for the operating status.
Warning
Risk of electric shock
The STO safety function only provides protection against dangerous movements, not against electric
shock.
Always comply with the stipulations of the documentation, in particular 2 Safety, Page 6.
Comply with the documentation for the other components.
Ensure protection against the built-in nutrunner automatically restarting according to the required safe-
ty category of emergency stop applications, e.g. via an external safety relay.

When the STO safety function is active, the power supply
is safely interrupted by two separate shutdown paths to the
motor in the tool. The motor can not produce any torque
and therefore no dangerous movements. There is no moni-
toring of the standstill position. This is relevant, for exam-
ple, for torques generated by loads, such as suspended
loads, or by preloaded spring drives. In such cases, addi-
tional measures for shutdown must be provided that pre-
vent these reactions - these must be ensured and brought
about in a safety-related manner.
9.2.1 Diagnostic Coverage (DC)
The Diagnostic Coverage depends on the inclusion of the
integrated safety function for the controller into the
controller chain, as well as the implemented measures for
the diagnostics.
If a fault is detected during the diagnostics, suitable mea-
sures must be provided to maintain the safety level.
9.2.2 Interface overview
The STO safety function for the controller is controlled via
the digital I/O interfaces X41, X42. The interfaces for all
controllers with the STO function are designated the same,
color-coded and functionally identical with the same speci-
fications, see 5 Pin Assignment, Page 12.
The STO safety function is requested exclusively via the
two digital control inputs STO-A and STO-B. Another con-
nection of the signals, e.g,. feedback or auxiliary voltage, is
not absolutely required.
The state of the STO safety function is reported back via a
potential-free feedback contact (closer). This information is
linked in a successive circuit of several controllers with the
STO function.
Interface port X41 – IN
Depending on the position of the currently considered con-
trol in the STO line (see 11 System, Page 114), the inter-
face port X41 is the connection to the previous controller or
to the external safety relay.
By providing an auxiliary power supply of 24 VDC in con-
nector X41, it is possible to supply the voltage to safety
relays for normally open contacts, or similar.
Interface port X42 – OUT
Depending on whether the currently considered controller
is the last in an STO line, or whether another controller fol-
lows, the interface X42 is the connection to the next
controller or can be left without connecting further. If the
feedback contact is evaluated, a termination on the last
controller in a line is necessary.
Caution
There is a risk of the motor starting up when
there multiple errors in the controller.
If the final stage of the nutrunner module
in the controller fails during the STO state
(simultaneous short circuit of 2 power
semiconductors in different phases),
there may be a limited locking movement
of the rotor in the motor. The angle of ro-
tation corresponds to a pole pitch, which
acts on the output drive with the gear re-
duction. The angle of rotation for electric
hand tools from Cleco Production Tools is
always ≤15°.
Note
Cross-connection detection of the input cir-
cuit is not performed by the controller.
All system components allow the short cir-
cuit fault exclusion.

9.3 Control signals STO-A and STO-B
With the two control inputs STO-A and STO-B, the STO
safety function is requested by two channels. They allow
the direct connection of safe semiconductor outputs (elec-
tronic safety relays, active safety sensors) and of switching
contacts (safety relays with relay outputs, passive safety
sensors, such as positively driven position switches),
see9.6 Assembly and installation, Page 19.
To request the STO safety function, the 24 V control volt-
age at both control inputs STO-A and STO-B is switched
off (0 V). If both control signals are switched off simultane-
ously or within a specified discrepancy time, then the STO
safety function is active.
Tolerance ranges are defined for the input voltage range of
the control inputs STO-A and STO-B. The amount of
energy stored in the components of the STO circuit (e.g.,
capacitors) depends on the magnitude of the input voltage.
During switching operations, these amounts of energy
must be charged or discharged. As a result, the dependent
values for the switch-off time for the transition to the safe
state (STO) come about from the input voltage.
The requirements for the time response result from the
technical specifications in Chapter 4 Technical Specifica-
tions, Page 10.The time response itself is described in
Chapter9.5 Time response, Page 19.
Discrepancy time
The transition between a safe and an unsafe state is initi-
ated by level changes at the control inputs STO-A and
STO-B. According to the specifications for the safety func-
tion, both levels must be identical; otherwise an error mes-
sage will be generated. A state machine in the controller
monitors both signals over time. Due to component toler-
ances or bouncing contacts, the level changes never occur
at exactly the same time. This is tolerated by the so-called
discrepancy time as long as the level changes occur within
this time. If the levels of the control signals STO-A and
STO-B are different for longer than this time, a transition is
made to an error state that can not be reset. The discrep-
ancy time Δt is 100 ms. This can not be parameterized.
Test pulses
Test pulses from safety controllers are not tolerated and
must be deactivated for system availability. The exclusive
use of Cleco Production Tools accessories allows the short
circuit fault exclusion.
Feedback contact FB
The feedback contact indicates the safe state. If the STO
safety function is not active, then the feedback contact is
open. This is also the case, for example, when the 24 V
logic supply voltage is switched off due to a defect or a fail-
ure of the supply voltage. When the STO safety function is
active, the relay contact is closed.
The following table shows the state of the feedback con-
tact, depending on the input signals and the time. A pre-
condition is always the error-free state (Row 1 or 4). The
time Δt is the discrepancy time 100 ms.
The technical specifications for the feedback contact are
given in Chapter 4 Technical Specifications, Page 10.

nel design and may be used for diagnos-
tic purposes, but not in the safety circuit.

may briefly deviate from the input signals

eration.

9.4 Diagnostics
The STO safety function is monitored in the controller for
plausibility and operability.
9.4.1 STO status signal to control
Within the software, the status of the STO safety function
(1=OK, 0=STO triggered) is available at Input 15 on the I/O
level under device PM_DIDO.
If this status information is present in the application, this
must be assigned accordingly by the operator.
It is advisable to use the software input Emergency Stop.
Assignment is not necessary for safety reasons.
9.4.2 Fail-Safe state
If a fault in the safety technology is detected, e.g., if, for
example, control signals STO-A and STO-B have unequal
levels or there is a circuit defect, then a fault is triggered
internally. This fault can not be reset or can only be reset
by a restart, i.e., further start attempts no longer lead to the
turning on of the output drive.
It is assumed that there is an external fault and the
controller must be switched off. If the fault persists after
checking the external controller, then there is a defect in
the controller and it must therefore be replaced.
9.5 Time response
The control signals STO-A and STO-B are equivalent in
regards to their use, although the signals operate different
shutdown paths. They are described in terms of the time
response as a single, exchangeable STO signal.
The time from the shutdown of an STO signal to the activity
in the final stage of the controller is determined by the
external circuitry (see also9.3 Control signals STO-A and
STO-B, Page 18), including controllers connected in paral-
lel. The values given here refer to the Passive version (see
9.6.1 Passive circuit X41, Page 19) with a nutrunner con-
trol and the maximum cable length. The time response is
different for each layout and must be checked at startup to
see if it meets the minimum requirements.
9.6 Assembly and installation
When installing and wiring the signals, the requirements of
EN 60204-1 must be met. In this case, particular attention
must be paid to measures for short circuit fault exclusion.
For the STO cables 961924-xxx, the STO signals are indi-
vidually protected by a ground connection. The connection
to the first controller, and from controller to controller, must
not be longer than 60 m; in total in the system, a total
length of up to 1000 m is permitted for all of the STO con-
nections.
The following circuit examples show the intended wiring of
the STO interfaces. An analogous other use or connection
is not permitted.
9.6.1 Passive circuit X41
Fig. 9-1:
The STO safety function can be requested by various devices. The switch S1 can be, for example, an Emergency Stop
switch, a safety door switch, a light curtain or a safety relay. The safety requirement is 2-channel via the switch S1and
leads to the 2-channel shutdown of the final stage - therefore, this structure is for Category 3. The auxiliary power supply
24 V for signal generation is provided on the interface.
9.6.2 Active circuit X41
Fig. 9-2:

20 P2552HW | 2021-04 Apex Tool Group
1
EN The STO safety function can also be requested through active, fail-safe outputs of a PLC or with contacts as in Chap-
ter9.6.1 Passive circuit X41, Page 19, but with an external power supply. For an external power supply, only PELV power
circuits and PELV power sources may be used. The voltage source must provide a nominal voltage of 24 VDC (an abso-
lute minimum output voltage of 22 VDC) with at least 0.5 A.
9.6.3 Shut down of STO safety function X41
Fig. 9-3:
If the STO safety function is not required in a controller, the function can also be deactivated by means of jumpers in a
connector as shown in the circuit diagram Fig. 9-3:.
9.6.4 Connection X42
Fig. 9-4:
The connection to X42 at the last controller in a system is only required if the feedback contact FB is evaluated. Otherwise,
the X42 interface can also remain open. For termination - which means closing the feedback path - use termination con-
nector 961893PT.
10 Operation and use
10.1 Obligation of the operator
Check the functioning of the safety device at defined time
intervals. It is the responsibility of the operator to choose
the type of test and the time intervals during the required
time period. The test shall be carried out in such a way that
the proper functioning of the safety device is demonstrated
in the interaction with all the associated components. The
maximum interval between two tests may not exceed a
duration of TPTI, see 4 Technical Specifications, Page 10.
10.2 Overvoltage and polarity reversal
protection
The control inputs STO-A and STO-B are protected against
overvoltages and against the polarity reversal of the control
voltage, see also Chapter4 Technical Specifications,
Page 10.
The 24 VDC auxiliary voltage supplied at X41 is short-cir-
cuit proof. However, a short circuit or overload leads to the
failure of alll the internal logic voltages and thus to the fail-
ure of the primary function.
Caution
