OPERATIONAL SEQUENCE OF TI-1000
The following passage will describe the normal operation sequence of the TI-1000 and some of the
problems that might prevent normal operation.
STEP 1: Before you try to cycle the TI-1000 please verify that the following LED’s are on. D3,
D4 (print signals) and D9 (print busy) should be illuminated when the TI-1000 is idle. If D3 and D4 are
not on, check the connection between H3 on the interface board and CN15 on the main CPU board. If
the harness is good, then replace the interface board and/or the main CPU board. If D9 is not
illuminated, then replace the interface board.
STEP 2: To initiate the print sequence, you must send a momentary print signal through the auxiliary
cable from AUX 3 on the bagger to the AUX IN port on the TI-1000. If the TI-1000 starts the print
cycle when the bagger is cycled go to STEP 4. Otherwise, See STEP 3.
STEP 3: If the TI-1000 does not initiate a print sequence, check the following:
Make sure T-1000’s print option is turned on and ensure that it is in the TT mode. Verify that you have a
good connection between the T-1000 and TI-1000 Assuming the T-1000 is providing the proper 24V
signal out, check D5 (AUX IN) for a momentary on pulse of approximately 0.25 second. If D5 is not
illuminating, replace the TI-1000 interface board.
STEP 4: After D5 illuminates, D9 (print busy signal) should turn off and D15 (head down output)
should illuminate. If D9 turns off and D15 illuminates then go to STEP 6. Otherwise, see STEP 5.
STEP 5: If D9 does not turn off or D15 does not illuminate, then replace the interface board.
STEP 6: The head should now lower and activate D1 (head down sensor). If the head does not lower,
then check the following:
Do you have air going to the valve?
Can the valve be activated manually?
Is the LED on the valve illuminating?
If the valve can be activated manually, check the harness between H9 in the interface board and the head
down valve. If the harness is good, replace the interface board.
STEP 7: After the head has lowered, D1 should be illuminated. If D1 is illuminated, then go to STEP
9. Otherwise, see STEP 8.
STEP 8: If D1 is not illuminating check the sensor flag to ensure that it is passing through the head
down sensor. If the flag is positioned properly, check the harness between H2 on the interface board and
the head down sensor board. If the harness is good, replace the head down sensor board and/or the
interface board.
STEP 9: Once D1 is on, D16 should turn on for approximately 0.25 second. This should cause D3 and
/or D4 to turn off and the printer should start printing. If the printer starts printing, go to STEP 11.
Otherwise see STEP 10.
STEP 10: If the printer is not printing, check the following:
Verify that D16 is illuminating.
If D16 is illuminating momentarily, check the harness between H10 on the interface board and/or the
main CPU board.
Additionally, if D16 is illuminating, check the harness between H3 on the interface board and CN15 on
the main CPU board.
STEP 11: When the printer is not printing, D3 and/or D4 will return to an illuminated state. This will
disengage the head-down valve and return D9 to an illuminated state. At this point, the bagger should
finish indexing the bag and complete the cycle.
