5.2 Using the application
Starting a machine
No.
Action
Note
1
Close the protective door.
2
Move the toggle switch into the position that
locks the protective door.
The voltage in the solenoid is switched off and the locking
mechanism moves into the actuator. The protective door is locked.
3
Unlock the emergency stop button.
4
Press the start pushbutton.
After the emergency stop button has been unlocked,
acknowledgment is required. The machine starts.
Unlock and open the protective door
No.
Action
Note
1
Move the toggle switch into the position
that unlocks the protective door.
The machine switches off and runs down.
2
Wait for the parameterized delay time
before unlocking the protective door.
In this example: 5 seconds
After the time has expired, the solenoid is supplied with power, and
moves the locking mechanism out of the actuator. The protective
door is unlocked.
4
Open the protective door.
Acknowledging other faults in the safety function
If another fault occurs in the safety function, the machine is immediately switched off and a
restart is prevented. Proceed as follows to acknowledge the fault.
Possible faults that are acknowledged in this way include:
• Cross circuit between the two emergency stop channels.
• External voltage on the fail-safe outputs
• Withdrawing a fail-safe module
• Contact welding of a contactor
No.
Action
Note
1
Check the LEDs on the fail-safe modules. If one
red LED illuminates, a fault in the hardware has
been detected. Search for the fault by means of
the online diagnostics in the TIA Portal.
2
If all LEDs are green, the safety program has
detected a fault. Look at the variable table to
find the fault.
The #fault and #ackReg variables of the
ProtDoorWithInterlocking block instructions can help with the
search.
3
Eliminate the fault.
4
Close the protective door.
5
Unlock the emergency stop button.
6
Move the toggle switch to lock the protective
door.
The voltage in the solenoid is switched off and the locking
mechanism moves into the actuator.
7
Press the start pushbutton.
Passivated channels of the fail-safe modules are re-integrated.
Faults detected by the safety program are acknowledged. The
machine starts.
