System Outputs Connector
The SYSTEM OUTPUTS connector mounted on the
generator I/O panel includes connections for all of the
basic system status and monitor output signals, which will
typically connect to an automated control system. The
cable attached to this connector includes all of the available
system output signals, which will be read or monitored by
a digital input card or analog inputs on the user-supplied
automation controller.
The user can determine which signals are appropriate for
each welding application.
The system monitor output signals are analog signals used to
monitor ultrasonic amplitude setting and ultrasonic output
power levels, referenced to the Monitor Common (Pin 13).
This is at system chassis ground potential (non-isolated).
All of the digital output status signals on this connector,
are isolated (signals are not referenced to generator chassis
ground). When a status output signal is activated, it will
sink current (500mA sourced by a 24VDC supply) to
isolated common. In automation terms, the outputs are
NPN (sinking) and would drive a PNP (sourcing) input
that is referenced to the Isolated Common pin.
The digital status output signals can only sink current to
isolated common. They cannot be changed to a sourcing
(PNP) type output. If sourcing status outputs are required,
there is an optional isolated NPN to PNP conversion
module that is DIN rail mounted. The module converts
the standard isolated sinking (NPN) status output signals
to isolated sourcing (PNP) status output signals. Consult
your local sales representative for information about the
conversion module.
System Outputs Connector Pinout
The SYSTEM OUTPUTS connector is a DB-25F
(standard D-subminiature 25 circuit female) connector.
Connector pin assignments for this connector are shown
in Figure 4–6. The male connector on the cable is a
mirror image of the panel mounted connector and is
shown in Figure 4–7. Table 4–II lists the signal names.
Detailed descriptions are listed in the System Outputs
Signal Descriptions section below. To assist with custom
automation system wiring and assembly, the wire color
coding for the system outputs cable is listed in Table
4–II.
System Outputs Signal Descriptions
Pin 1 (+22V Power Supply)
This pin can supply +22VDC at up to 250mA to power
the user’s automation controls.
Pin 2 (Not Used)
Pin 2 is an open connection.
Pin 3 (+22V Power Ground)
Pin 3 is the 22VDC return and is tied to the system
chassis ground.
Pin 4 (Programmable Status Output 1)
Pin 4 is a digital active low status output that can be
reprogrammed and assigned to another system status
signal (from the available selections) using the front
panel controller.
Pin 5 (Programmable Status Output 2)
Pin 5 is a digital active low status output that can be
reprogrammed and assigned to another system status
signal (from the available selections) using the front
panel controller.
Pin 6 (Ultrasound Active Status Output)
Pin 6 is a digital active low status output that activates
when the system is delivering ultrasonic power to the
load attached to the ultrasound output connector. This
output will be an open circuit when the ultrasound output
is off.
