5.8 REMOTE PENDANT (RP) OPERATION
3. (continued)
When the weld sequence is started the display will indicate progression through
PURGE, UPSLOPE, LVL 01 (etc.), DOWNSLOPE and then
POSTPURGE.
4. The Override Keys allow the operator to change Amps, Volts, TVL, OSC and
Wire Values (with-in set limits) . After a Pass is called up pressing one of these
keys will change the display to show the value of that function. Using the Arrow
Up key will then increase the amount . Using the Arrow Down key will then
decrease the amount.The same Operation can also be done DURING SEQUENCE
as well.
Overridden values only stay as long as that pass is displayed. If another pass is
called up and then the original one is called up again the values will be as
originally programmed, not as previously overridden. With the Operate Mode
key in PROGRAM it is possible to save or MODIFY the original parameters
with the new overridden values . See Special Function Key operation (step 5)
for more details.
Using the Override Keys only OVERRIDES the function value in the
LEVEL displayed . During Sequence you cannot Override a value in
another LEVEL . Before Sequence it can be done by use of the MAN ADV
special Function. See Special Function Key operation (step 5) for more details.
5. SPECIAL FUNCTION KEY - The Pendant Special Function key allows access
and manipulation of many additional functions. This feature works ONLY
WHEN NOT IN WELD SEQUENCE. Each time the Special Function key is
pressed the display will change in the following order :
1. PASS - This allows the user to select the next or previous pass in the Weld
Schedule . Pressing the NEXT Key will access the next pass, if there is
one. Pressing the PREV Key will access the last pass, if there is one .
When pressed the display will leave the Special Function and show the
Weld pass # and System mode (002 TEST) as previously described.
2. PURGE - Press the NEXT Key to manually change the state of the Gas
Solenoid . It will turn ON or OFF depending on its condition . Press the
NEXT Key again to return the Gas Solenoid to its original state . You can
continue to cycle the Solenoid in this way until another function is chosen
(like jogging, etc.).
