Abstract
Exemplary embodiments are directed towards safety systems associated with ultra-fast fault signal pulses to increase the fault signal pulses from milliseconds to seconds to energize external devices (e.g., LED lights). This is turn will alert the operators that the system is operational or a fault was detected. The fault signal width pulses are extended to drive or trigger external devices, such as external relays, which in turn completes a circuit to energize any external devices.
Claims4
A fault signal system comprising:
- a timing delay circuit;
- at least one delay circuit relay;
- a first and a second connection point;
- and
- a switch relay;
- wherein the first connection point is configured to connect to a device under test;
- wherein the at least one delay circuit relay forms a closed delay circuit when the device under test experiences a fault;
- wherein a default signal is provided to the switch relay when the delay circuit relay is open;
- wherein a delay signal is provided to the second connection point when the delay circuit relay closes.
