7.6.1 Manual Reset Input
The Manual Reset input may be configured to perform any combination of the following (see
on page 62):
Reset of Safety Inputs
Sets the output of the Latch Reset Block(s) to a Run state from a Latched state when the IN node is in a Run state
Reset of Safety Outputs
Sets the Output to On if the Output Block configured for Latch Reset is On.
Exceptions:
A Safety Output cannot be configured to use a Manual Reset when associated with a Two Hand Control input or an
Enabling Device Function Block.
System Reset
Sets the System to a Run state from a Lockout state due to a system fault. Possible scenarios when System Reset
is needed include:
• Signals are detected on unused terminal pins
• Configuration Mode timeout
• Exiting Configuration Mode
• Internal faults
Output Fault Reset
Clears the fault and allows the output to turn back On if the cause of the fault has been removed. Possible
scenarios when an Output Fault Reset is needed include:
• Output faults
• EDM or AVM faults
