Prog0-7
Program 0-7 Program selection
These eight inputs are used to transfer the binary encoded program number to the tightening controller.
The program number is valid within the tightening controller if the program acknowledgement signals
correspond to the selected program. The program number must be selected and acknowledged by the
system before the start of the tightening.
ResF
Reset Fault: Resets a system error
This input allows acknowledging a system error of error class 3. The system error is acknowledged
provided error acknowledgement is allowed.
ResRs
Reset Result: Resets a result
We recommend resetting the results before every restart.
ResRs
signal = "high" sets the
CyCmp
and
OK
signals, the monitoring function signals,
e.g.
TorqH
, and the
TrigOut
signal to "low", and the
NOK
signal to "high".
Resetting the result (signal value is "high") does not delete the ID code in the input buffer. This allows
using the sequence number.
In order to delete the ID code after tightening has been started, the
Delete ID code after start
option
must be activated in the NEXO-OS operating system, in the ID input step mode.
WasByPass
WAS Bypass: Order nutrunner via PLC\LisWAS is ignored
With the signal
WasByPass
= "High", the order nutrunner via PLC\LisWAS is ignored. The order is then
only possible via scanner. An active job is canceled and evaluated with NOK.
If the signal changes from "High" to "Low", a PLC\LisWAS order can be executed again.
The signal can only be transmitted when the data service
BMW-TPC
is active.
If the
NOKAc
signal is assigned to input 0.3, 0.4 or 0.5 in the PLC table, the signal is inverted, i.e. the
signal changes to "low" when the functional key is pushed, and to "high" when it is released.
If the OK/NOK counter is configured as required for the program, the counter will be automatically
selected when the program is selected.
