The following steps with the PLC start-up switch S4 will cause a
PLC GENERAL RESET:
1. Turn to position “2” (STOP operating state)
⇒ PS LED lights up.
2. Turn to position “3” (MRES operating state, request general reset) and hold
in this position (for approx. 3 second) until the PS STOP LED lights up
again.
⇒ PS LED goes out and comes on again.
3. Within 3 second, turn to the
STOP-MRES-STOP (“2”–“3”–“2”) positions
⇒ PS LED PS first flashes at approx. 2 Hz and then lights up again
⇒ PF LED lights up
4. Once the PS and PF LEDs are lit, turn the switch S4 to position “0”
⇒ The PS and PF LEDs goes out and the PR LED (green) lights up
⇒ A general reset of the PLC is complete. It is now in cyclical mode.
