Sequence Timing of the "Ohma® Cylinder"
Close Gun Time:
| From Full Open | Close Gun time is defined by the setup parameters - "Close to pre-Block Time" + "Advance Stop Time" + the function "TURN ON ADVANCE VALVE" time |
| From Partial Open | Close Gun time is defined by the function "TURN ON ADVANCE VALVE" time. |
Intensify Gun Time:
| Intensify Gun time is defined by the function"TURN ON INTENSIFICATION VALVE" time |
Open Gun Time:
| To Full Open | Open Gun time is defined by the setup parameters - "Open from Block Time" + (if using function #17 - the setup parameter "GUN # n OPEN TO BLOCK POS" or if using function #18 - the function "TURN OFF INT/ADV VALVE" time. |
| To Partial Open | Open Gun time is defined by (if using function #17 - the setup parameter "GUN # n OPEN TO BLOCK POs" or if using function #18 - the function "TURN OFF INT/ADV VALVE" time. |
The Blocking Valve Output is ONLY active while the cylinder is being held between full open and full closed.
If the control's Retract Pilot setup parameter is in the unlatched mode, the control will return to the partial retract position if, at the turn of intensify/advance valve function, the retract pilot is high, however it is in the low state, it will return to the full open position.
If the control's Retract Pilot setup parameter is in the latched mode, the control will return to the position it started the weld schedule. If the control does not know what position it is in, it will return from the full closed position to the partial retract position. An example of this is using the opening option before the control welds (see I/O Timing Diagram for After Closing Movement and Before Weld Operation).
Full Open to Partial Retract Time is defined by the setup parameter "Close to Pre-Block Time" + "Advance Stop Time".
Partial Retract to Full Open Time is defined by the setup parameter "Open From Block Time" + "Advance Stop Time".
Open to Blocked Position:
The Gun Moving is defined by the setup parameter "Open to Blocked Position".
