11.2 Live Mode Information: Software
To display real-time Run mode information on a PC, the Safety Controller must be connected to the computer via the USB
cable. Click
Live Mode
to access the
Live Mode
tab. This feature continually updates and displays data, including Run,
Stop, and Fault states of all inputs and outputs, as well as the Fault Codes table. The
Equipment
tab and the
Functional View
tab also provide device-specific visual representation of the data. See
information.
11.3 Lockout Conditions
Input lockout conditions are generally resolved by repairing the fault and cycling the input Off and then back On.
Output lockout conditions (including EDM and AVM faults) are resolved by repairing the fault and then cycling the Reset
Input connected to the FR node on the Safety Output.
System faults, such as low supply voltage, overtemperature, or voltage detected on unassigned inputs, may be cleared by
cycling the System Reset input (any Reset Input assigned to be the System Reset). Only one reset button, either physical or
virtual, can be configured to perform this operation.
A system reset is used to clear lockout conditions not related to safety inputs or outputs. A lockout condition is a response
where the Safety Controller turns Off all affected Safety Outputs when a safety-critical fault is detected. Recovery from this
condition requires all faults to be remedied and a system reset to be performed. A lockout will recur after a system reset
unless the fault that caused the lockout has been corrected.
A system reset is necessary under the following conditions:
• Recovering from a system lockout condition
• Starting the Safety Controller after a new configuration has been downloaded
For internal faults, the System Reset likely will not work. The power will have to be cycled in an attempt to run again.
