Unitrol SOLUTIONi - FULL or HALF CYCLE COUNT

SECTION C, PAGE 16
SOLUTION PERSONALIZATION
In this mode, the CLAMP wired to SV1 turns on at the same time that the weld
head SVO is turned ON. At the end of the sequence, SV0 turns OFF and then
after the CLAMP DELAY in the welding program the CLAMP releases. This can
be used to keep parts in place for cooling, or can be used to operate a water
solenoid valve that floods the part during an operation and stays on for a selected
time afterwards.
If you use any of the CLAMP functions
above, the J2 jumper on the power
supply must be set to the ON position as
in this photo.
If you are using any of the CLAMP DELAY functions, DO NOT OPERATE
THE WELDER IF THIS JUMPER IS NOT IN THE “ON” POSITION.
C10.4 TURN ON WITH LEVEL 2: Press 5 and the display will show:
In this mode, the SV0 output will turn ON only after the second level of the FOOT
SWITCH is closed.
C11 FULL or HALF CYCLE COUNT: Normal resistance welding uses
full line cycle weld timing. But if you are welding very thin material and need to
have ½ cycle of WELD TIME, or are doing a very sensitive weld that needs timing
in ½ cycles, change the SOLUTIONi control as follows:

PROGRAM
SVO FUNCTION IS:
TURN ON W/LEVEL 2=5
This can be used to clamp a part when the first level of the FOOT
SWITCH is closed. Then if the part looks to be in the correct positon,
closing of the second level of the FOOT SWITCH will close the welding
electrode. This is often used for critical assemblies or for resistance
brazing operations.
