System Outputs
(Optional Connections)
The OUTPUTS connector is a four-position wire receptacle-type terminal block. If needed, it can provide the operator with basic system welding status. Everything connected to the OUTPUTS connector is customer- supplied. Typically indicator lights or sound modules are powered by these output signals. (The lights or sound modules can be mounted on widely available Stack Light assemblies.) Each output signal is rated to operate on a 24VDC power source and can activate an attached load up to a maximum of 500 mA.
Table 3-II lists the signal names.

Table 3-IISystem OUTPUTS Connector Signals
NOTE
All outupt signals are non-isolated and sink current to chassis ground when activated.
Pin 0V (Output Common)
Pin 0V is connected to chassis ground.
Pin 1 (End of Weld Alarm)
Non-isolated NPN output that sinks current at the End of Weld cycle. It activates when ultrasound switches off, or at the end of a preset Hold period. The signal lasts for one second, then deactivates.
Pin 2 (Any Fault Alarm)
Pin 2 is a non-isolated digital NPN status output that sinks current to chassis ground if any fault condition is sensed. This output is active until the start of the next cycle or until ENTER is pressed if in non-latching fault mode.
In latching fault mode the user must press ENTER to clear this output.
If a hardware fault like Over Temperature or a power fault occurs, Any Fault is active until the fault is cleared in non- latching fault mode. In latching fault mode, the user must press ENTER to clear this output. However if the fault persists, pressing ENTER has no effect.
Pin 3 (Bad Part)
Pin 3 is a non-isolated digital NPN status output that sinks current to chassis ground if a Bad Part is detected. This output is active until the start of the next cycle or until ENTER is pressed if in a non-latching fault mode. It is active until ENTER is pressed if in a latching fault mode.
NOTE
Refer to Figure 9-1, OUTPUTS Inter- face Example, Page 65.
