K940 SENSE LEADS: These leads are used to accu- rately sense arc voltage. One set is required for each STT II power source. A 10 ft and 25 ft set are provid- ed as standard with the machine. Additional sets are available in 10 ft (K940-10), 25 ft (K940-25) and 50 ft (K940-50) lengths.

K942-1 REMOTE CONTROL: Allows remote adjust- ment of Peak and Background Current settings.

REMOTE RECEPTACLE (For optional remote interface, Connection to the STT-10 Wire Feeder or Robotic Control)

1.The 10 pin MS connector labeled “Remote Control” located on the front panel of the STT is used for remote control of the power source. Control for the PEAK (PB pot) and BACKGROUND (BG pot) cur- rent along with the trigger switch is provide through this connector.

2.Refer to figure C.1 below for details about the remote receptacle (J38). Note that pins “J” and “B” are shorted together This “short circuit” tells the

REMOTE

PROTECTION BOARD

STT control board to accept PEAK and BACK- GROUND inputs on this connector rather than from the front panel controls. If this short is removed, the front panel controls will be active. By adding a switch between pins “J” and “B” a “LOCAL/REMOTE” control switch can be created. (Switch open for “local” and closed for “remote”)

3.For robotic control of the PEAK CURRENT, a 0 to +10 volt DC signal is applied between pins “A” and “G” with + applied to pin “G”. The BACKGROUND CURRENT is controlled with a similar signal applied between pins “A” and “C” with + applied to pin “C”. In this application pins “J” and “B” must be shorted as described in 2 above.

NOTE: These analog signals should be isolated from the robot circuitry to prevent interference.

4.The trigger switch is connected between pins “D” and “F”. These connections are in parallel with the trigger switch from the wire feeder.

5.The digital meters for PEAK and BACKGROUND currents will show preset values in both local and remote operation.
