The timer assembly provides five connectors for system
communications:
• Local DEP port J8: Connect a DEP-100S Data Entry Panel to port
J8 to program the control’s basic operating parameters and to set its
network address. This connector requires using the door/remote I/O
interface kit (WTC p/n 830-0654).
• MedLAN port J2: Use connector J2 to link the weld control to
other controls and a network monitoring system through the Local
Area Network (
MedLAN ).
• Firing Card port J9: This connector links the timer assembly
board to the firing card.
• Ports J6, J7: These connectors link the timer assembly to
communicate with up to two Discrete I/O boards.
The weld processor performs the following weld timing functions
required to execute a weld schedule:
• Checks input signals (provided through the Discrete I/O board)
from the I/O modules (either FieldBus or Local I/O) and responds
to them accordingly.
• Operates the signals (through the Discrete I/O board) based on the
weld schedule.
• Sends firing signals to the firing card as required by the weld
schedule.
• Receives sense signals for line voltage, current and power factor
from the firing card.
• Adjusts the firing signal, based on the power factor and the line
voltage or primary current, based on how the weld schedule is
programmed.
LED indicators on the weld processor module show control status.
FieldBus Daughter
Board
The FieldBus daughter board is part of the timer assembly. Depending on
its design, this board implements either of the following interfaces:
• Profibus or
• DeviceNet DP.
