CHAPTER 4: CONTROLS
2 KHZ INVERTER WEDLING POWER SUPPLY
990-057 4-9
Control Signals - Remote Weld Schedule Selection Input
All weld schedules must be entered and saved using the Power Supply Front Panel keys. After saving the
desired weld schedules, each schedule can be recalled prior to initiating the welding process cycle. Using
the PLC (Figure 4-8), remote weld schedule selection (chain schedule feature turned off) can be
implemented by closing the binary Remote Schedule Select lines according to the following table:

Binary progression from 3 to 126

NOTE: 0 = Open; 1 = Closed
Using a remote chain control box in place of the PLC, a semi-automatic chain weld schedule can be used
to control the remote schedule select lines through the Control Signals Connector in accordance with the
following table:
Pin No. Function Description
1 Schedule Down Decrement the schedule number
2 Schedule Up Increment the schedule number
3 Reset Set the schedule number = power up schedule number
4 Auto/Manual Enable (Auto)/disable (Manual) the chain schedule function
Note: If (Manual) is selected on pin 4, the chain control box will override the Control chain schedule
on/off function and weld schedules can be selected manually from the chain control box (see Figure 4-9).
Control Signals - Emergency Stop Input (Figure 4-8)
Connect a reed relay, or the open collector of an opto-coupler to Pin 10 of the Control Signals connector
to immediately terminate the welding process. No welding process can be initiated until the switch closure
has been removed. The emitter of the opto-coupler must be connected to Pin 11.
Control Signals - Process Inhibit Input (Figure 4-8)
Connect a reed relay, or the open collector of an opto-coupler to Pin 9 of the Control Signals connector to
prevent a new welding process from beginning. No welding process can be initiated until the switch
closure has been removed. The emitter of the opto-coupler must be connected to Pin 11.
