the nutrunner display will continue to be displayed. The user is not notified that the scanner is disabled
via PLC signal.
En Enable: Enables
When the
En
signal is "high", it acts as a nutrunner start enable signal. If the
En
signal changes to "low"
during a tightening process or sequence, the process or sequence will be canceled and the tightening
program is evaluated as NOK.
JobAbort Job Abort: Aborts a job
This signal aborts a currently running job.
JobEnable Job Enable: Activate job
This signal activates a job.

This signal sets the OK evaluation to “0”, NOK to “1” and JobCyCmp to “0”.

This signal starts a job.
Job0-7 Job 0-7: Job selection
Using these bits, the jobs 0 to 249 can be selected.
These eight inputs are used to transfer the binary encoded job number to the tightening controller. The
job number is valid within the tightening controller if the job acknowledgement signals correspond to the
selected job. The job number must be selected and acknowledged by the system before the job
sequence is started.
ManOp Manual Operating Mode: Activate manual mode
This signal activates the manual mode for the nutrunner if in the start step at mode, the
PLC signal
ManOp
option has been activated under
Trigger.
If the nutrunner changes into manual mode, the signal
is set to "1".
NokAc Not OK acknowledge: NOK acknowledge
The tightening system also provides you with an option to prevent further starts after an NOK tightening.
A restart is only possible after the
NOKAc
signal has been set to "low".
This function is active if the signal
NOKAc
is set to "high" at the starting point. If tightening is evaluated
with NOK, the tightening system is ready to restart after the
NOKAc
signal has been reset to "low". The
system is ready to start when the
InCy
or
InCyCcw
signal is shown to be "low". Setting
NOKAc
to "low"
will also reset
NOK
on the PLC interface.
If it is configured for the job, the OK/NOK counter is automatically selected when the job is started.
The
NOKAc
signal must be set to "high" before the
Cw
or
Ccw
signal so that the signal will be considered
for this tightening.
After commissioning of the Nexo cordless Wi-Fi nutrunner, the signal
NOKAc
is set to “high” by default if
it is applied on the
tool
PLC module. To start the nutrunner, the signal has to be set to “low”.
