7.2 Reset I/O Fault
The device switches to the "I/O Fault" state if a fault has been detected at the inputs or out­
puts. Once it has been rectified, the fault must be reset.
There are three options for resetting an "I/O Fault" and restarting the device.
Option one: Switch supply voltage A1/A2 off and then on again
1. Switch off the device's supply voltage (terminals A1 and A2)
2. Switch the device's supply voltage back on.
The device restarts.
Option two: Display menu reboot
1. Select Reboot in menu level 3.
2. Select Yes and press the rotary knob.
The device restarts.
Option three: Switch inputs Y10/Y11 or Y20/Y22
This option should be considered if you wish to reset the fault from the higher level control
system.
Using one power circuit:
} The fault is reset by a 1/0 pulse edge at one of the inputs Y10/Y11 or Y20/Y21.
} A 0/1 pulse edge switches on the corresponding power circuit.
