6.2.4 Input forward and backward on (Both Inputs On)
The fault is also generated if the two inputs forward on (E1) and
backward on (E2) are simultaneously activated by the controller for
longer than 120 ms. In this case the outputs forward start (A1) and
backward start (A2) are switched off and blocked until E1 and E2
are off again. If E1 and E2 are off, after 3s the overrun faults
forward/backward A4 and A5 are reset.
In the SmartTurn_V14 EXE diagnostics software when the fault
occurs, the fault message "Both Inputs On" is set, this fault
message remains until reset or switch-off of the 24V supply.
NOTE!
If the fault occurs you must follow the instructions in
section -> 6.2.1
Overrun forward / backward .
Possible causes:
Measures
Forward on (E1) and backward on (E2) are activated
simultaneously by the PLC for longer than 120 ms
Check and correct the PLC activation

6.3 System faults
System faults are faults that compromise safe operation of the
turntable.
If a system fault is detected, then the two outputs
A1
and
A2
are
blocked and the
"System fault“ A6
output is output as group fault.
A detailed fault analysis is possible via the diagnostic interface with
the diagnostic software.
The following system faults are displayed in the diagnostic
software.
Extended diagnostics with the data logger tool
With a separate data logger tool you can read out the last 10s prior
to occurrence of the fault, thus all relevant diagnostic data is
secured and allows detailed fault analysis. The diagnostics data
will remain accessible until the system fault is deleted on the
turntable controller.
Use of the tool requires consultation with Expert Tünkers.
