Basic operation
12
•
External input terminals
Note
Use no-voltage signal; such as no-voltage relay contact or
open collector output, to short-circuit or open the input ter-
minals. Applying voltage to the input terminal damage the
P.C. Board.
Name Description Switch means
•
Start I
• Short-circuit the termibals to to start welding oper-
ation.
• With 4-schedule start mode:
welding condition corresponding to the start input.
• With 15-schedul start mode:
those four start inputs are used as binary code to
select a welding condition.
DIP switch: DPSW1-1
(To select a starting mode)

•
Sequence stop /
Current off
• Normally it is short-circuited.
• Open the terminals for “sequence stop” or “current
off” depending on the DIP switch setting.
DIP switch: DPSW1-9
(To select a current off mode.)
•
Welding current interlock
input
• It keeps the welding current to flow while receiving
the interlock signal from another machine without
moving onto up-slope state.
-
•
Step-up shift
<When DIPswitch setting is for “Step-up” mode>
Input to shift to the next step.
<When DIPswitch setting is for “Signal-up” mode>
Input to increase the welding current by the preset
incremental rate.
DIP switch: DPSW1-10
(To select a current
incremental method.)
•
Step-up reset
or
•
Signal-up reset
• An input to reset the “Step-up” or “Signal up”
counter to zero.
• Use the input when needed such as at the time
the electrode tip is replaced.
DIP switch: DPSW1-10
(To select a current
incremental method.)
•
Welding counter reset input
• An input to reset the welding counter to zero.
-
•
Production counter reset
input
• An input to reset the production counter to zero.
-
•
Trouble reset input
• An input to reset the trouble output.
-
•
C.T. input *
• An input to be used when “Primary constant
current” is selected as current detecting system.
• In that case, connect CT to this terminal. (CT type:
FTU02003))
DIP switch: DPSW1-6
(To select a current detecting
system.)
