APPENDIX B: WELD HEAD CONTROL INPUT/OUTPUT SIGNALS
SERIES 300 FAST RESPONSE WELD HEAD SYSTEM
990-115 B-5
Emergency Shutdown Input
Connect a switch, reed relay or the
collector of an opto-coupler to Pin 10 of
the CONTROL SIGNAL INPUT
connector to immediately terminate the
welding process. No welding process
can be initiated until the inhibit status of
the input has been removed. The emitter
of the opto-coupler must be connected to
pin 11.
You can select the state of the input
(normally open or normally closed) with
the OPTIONS 1 screen. Refer to
Chapter 3 under
Options Selection.
Process Inhibit Input
Connect a reed relay or the open collector of an opto-coupler to pin 9 of the CONTROL SIGNAL
INPUT 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.
Output Relays
Output relays K1 and K2 (see figure B-
4) can be used to provide status or
timing signals to a Programmable
Logic Control (PLC) or host computer.
When used for status signals, the relays
can be independently programmed to
close:
(a) when an alarm condition exists
(b) during the RUN state
(c) during the weld period, or
(d) during the entire welding cycle.
As shipped, either relay can switch either AC or DC current. AC signals are limited to from 5 to 35
volts RMS at 0.5 amps maximum. DC signals are limited to from 5 to 50 volts at 0.7 amps. Polarity
does not have to be observed.
