System I/O Signal Descriptions (J1)
Pin 1 (Solenoid Output)
This pin is a non-isolated digital active low status output
that is active from start of a cycle to end of Hold (refer-
enced to chassis ground).
Pin 2 (In Cycle Status Output)
Pin 2 is an isolated digital NPN/PNP status output ref-
erenced to Output Common that is active from start of a
cycle to end of Hold.
Pin 3 (Front Panel Control Lock Input)
Pin 3 is used to lock the front panel user interface, so
an operator cannot change any welding configuration
parameters that are stored in memory. The user can use
the interface controls to view welding information, but no
changes are allowed. Deactivation of this signal allows
normal operation, without any lockout restrictions.
Pin 4 (READY RELAY NO Output)
Pin 4 is the normally open contact of the Ready Relay that
is connected to the Ready Relay Common pin when the
system is ready to begin a weld cycle. This output will be
an open circuit when the welding process controller deter-
mines that the next welding cycle cannot be started. This
will occur if the system is in cycle, a system fault is active,
or the system is off line, but not as a result of a process
fault like Overload.
Pin 5 (READY RELAY Common)
Pin 5 is the Ready Relay common pin.
Pin 6 (Not Used)
Pin 7 (Not Used)
Pin 8
(+22VDC Power Supply)
This pin can 22VDC.
Pin 9
(+22VDC Power Supply)
This pin can 22VDC.
Pin 10
(Bad Part Status Output)
Pin 10 is an isolated digital NPN/PNP status output that
activates, either momentarily or until the start of the next
welding cycle, when the welding parameters recorded
during the previous welding cycle are outside of the
programmed bad part limits. This output will be an open
circuit when a bad part has not been detected.
Pin 11
(Top of Stroke Status Output)
Pin 11 is an isolated digital NPN/PNP status output
that activates when the press/thruster head is in the top
of stroke position. This output will be an open circuit
when the press/thruster head is not at the top of stroke
position
.
Pin 12 (Not Used)
Pin 13 (Hold Status Output)
Pin 13 is an isolated digital NPN/PNP status output
that actives when the press is in the Hold portion of the
weld. This output will be an open circuit when the not
in Hold.
Pin 14 (System Latch Reset Input)
Pin 14 is used to reset the Any Fault or System Overload
status outputs (See Status Output descriptions.). If a fault
occurs during a weld cycle, these outputs will normally
remain active until the next weld cycle is initiated. Ac-
tivating this input will reset the status output faults and
may simplify automation programming.
Pin 15 (Input Common)
Pin 15 is electrically isolated from chassis ground.
Using isolated sourcing (PNP) output drivers, this
common line would be connected to isolated ground
potential. Using isolated sinking (NPN) output drivers,
this common line would be connected to the isolated
positive supply volt age output.
