FT1330 Troubleshooting Checklist
PROBLEM
SOLUTION
Machine will not cycle
1. Make sure motor is running in proper direction by
manually shifting directional control valve to extend and
retract cylinder.
2. If no movement is obtained in #1, pump is defective or
motor is running in reverse.
3. If movement is obtained in #1, remove power from
machine and check continuity of foot switch at terminals
17, 18 and 5 inside control box with a continuity tester.
With switch up, 5 and 18 should show a short and 18 and
17 open. With switch depressed, 5 and 18 should show
an open and 18 and 17 a short.
4. If #3 is okay, with power removed, jumper wire 21 to wire
1 (23 to 1 if 230V machine). Plug machine in and turn
machine on for one second only. If cylinder extends,
replace control board. If not, replace valve.
Machine crimps and returns, but will not crimp again
1. Turn machine off. Wait three seconds for the machine to
reset and turn back on. Depress foot switch. If machine
now crimps, Ret. Lim. potentiometer is out of adjustment.
Remove power, open control box, plug machine back in
and turn on. Cycle machine, when fully retracted, power
unit will sound different. Adjust Ret. Lim. C.C.W. until red
LED comes on then 1/4 turn more. If the red light does
not work, replace control board.
NOTE: Electrical checks should be done by a qualified
electrician.
