Timer Inputs (P1)
[FSC] Foot Switch Common (P1-1 or P1-12)
Input Common connection - serves as common point for FS1, FS2, ES1, NW1, and PI1 - PI6. Inter-
nally connected to 24VDC.
[FS1] Foot Switch #1 (P1-2)
Used as start/initiation input for weld sequences. When connected to FSC, it will be active and draw
10 mA. May be used alone as Single Stage Foot Switch or Stage 1 of a 2-Stage Foot Switch. Acti-
vates Internal Control Relay 1 (CR1). For more information on using a Two Stage operation, see Sec-
tion 5.4. Do not use solid state control devices; only use dry switch contacts without snubbers.
[FS2] Foot Switch #2 (P1-3)
Used as a start/initiation input for weld sequences. When connected to FSC, it will be active and draw
10 mA. May be used alone as a Single Stage Foot Switch or Stage 1 of a 2-Stage Foot Switch. Acti-
vates Internal Control Relay 1 (CR1). For more information on using a Two Stage operation, see the
Section 5.4. Do not use solid state control devices; only use dry switch contacts without snubbers.
[ES1] Emergency Stop (P1-4)
When open, the control stops any and all processes (all valves and firing pulses turn off). While in
Emergency Stop condition, Status Page 1 will display Error Code 09 until the condition has been
cleared. If the execution of a schedule was interrupted by means of this switch, the control will not re
initiate automatically (after the Emergency Stop condition is removed). Upon release of this switch, it
must be re-initiated by closing FS1 or FS2.
[NW1] No Weld Signal (P1-5)
External Weld/No Weld input. Close for Weld; open for No Weld. When active, it will draw 10 mA.
When welding, it will draw 300 mA. When open, no source voltage is provided to the weld firing cir-
cuit and the control cannot weld.
[PI1] Programmable Input #1 (P1-6)
Use as a multi-purpose programmable input. Via programming, it may be used as transformer temper-
ature limit switch (TT1), 2nd Stage, Back Step, or Part Counter Reset (PCTR) input. See Section
5.4 for more information. When connected to FSC, it will be active and draw 10 mA.
[PI2] Programmable Input #2 (P1-7)
Used as a multi-purpose programmable input. Via programming, it may be used as Edit Lock, Pres-
sure Switch (PS1), Interlock, or Weld Counter Reset (WCTR) input. See Section 5.4 for more infor-
mation. When connected to FSC, it will be active and draw 10 mA.
[PI3] Programmable Input #3 (P1-8)
Used as a multi-purpose programmable input. Via programming, it may be used as Error Reset, Sch.
Select 1, Stepper Reset, or 2nd Stage input. See Section 5.4 for more information. When connected
to FSC, it will be active and draw 10 mA.
