CLE SEQUENCECLE SEQUENCE
CLE SEQUENCECLE SEQUENCE
CLE SEQUENCE: After the mode push button is in the AUTO position and the job has been
Programmed into the PLC, and the Cycle Start push button pressed:
1) Hydraulics running, the head should move to it's up limit, if it is not already there. Shuttle
vise should open and come forward to the home position. HUP input light must come on
for cycle to continue.
HUP input on - cycle should continue, if not check outputs per step 2.
HUP input not on - check that head up limit switch is being actuated, check limit switch/
limit switch wiring.
2) Front vise should be closed, the shuttle vise should stay open and move back to the
programmed length;
FVC output should be on SVO output will light momentarily, REV output and FST output
should be on when the shuttle moves back fast.
3) As the shuttle approaches target length the FST output should shut off and the shuttle
should travel slow for the "Dec. Dist." parameter, cushion distance. (i.e. 1.00") When
the shuttle reaches target length, the SVC output should light, and the shuttle vise
should close on the material.
4) FVO output light should come monetarily on and front vise should open.
5) FWD output should light as will as FST for the shuttle to move forward in fast speed. FST
will turn off when the shuttle home cushion period is reached and the shuttle should
slow down into the home position.
6) FVC output should light and the front vise should close. FWD light should go out, HDN
output should come on and the head should start to descend for the cut. If blade is not
running at this time, auto cycle will hold until min. SFM is reached. Depending on "Hld
Shtl Hm" parameter in the PLC, the shuttle may stay home and closed during the cut or
may move back to pick up the next length. HUP input should go out as the head
descends, and HUP L/S deactivates.
