637 APC Unload Switch Missed PAL 2
Pallet #2 did not return from the receiver to the APC in the allowable amount of time. This can be caused by the
chain switch block missing the limit switch, or from another mechanical problem, such as clutch slippage. After
correcting the condition, run an M50 to continue machining.
638 APC Door Not Open
The automatic door did not open (in the time allowed by Parameter 319 “APC door close time”) or may have
fallen during an APC function. This can be caused by a bad air solenoid, a blocked or kinked air line, or a
mechanical problem. After correcting the condition, the M50 must be rerun to continue machining.
639 APC Door Not Closed
The automatic door did not close (in the time allowed by Parameter 319 “APC door close time”) when neces-
sary after an APC function has been performed. This can be caused by a bad air solenoid, a blocked or kinked
air line, or a mechanical problem. After correcting the condition, the M50 must be rerun to continue machining.
640 APC Missing Pallet @ Receiver
Pallet change sequence was halted because receiver switch was not activated. Pallet is either unclamped or
not on the receiver. Ensure the pallet is correctly located on receiver (against hardstop) then run M18 to clamp
the pallet. After correcting the condition, the M50 must be rerun to continue machining.
641 APC Unknown Chain Location
Neither Chain Location switch is tripped, so the control cannot locate the chain position. This can occur if a
pallet change is interrupted for any reason, such as an alarm or an E-STOP. To correct this problem, the pallets
and chain must be moved back into a recognized position, such as both pallets home or one pallet home and
one on the receiver. The chain position adjustment tool must be used to rotate the chain into position. The
pallets must be pushed into place by hand. After correcting the condition, run an M50 to continue machining.
642 APC Incorrect Chain Location
Chain not in position to load or unload pallets when necessary. To correct this, the mislocated pallet must be
moved back into the proper position by hand. After correcting the condition, run an M50 to continue machining.
905 NO P Code In M14, M15, M36
In M14, M15, M36 must put pallet number in a P code.
906 Invalid P Code In M14, M15, M36
The P code must be the pallet number of a valid pallet without a decimal point, and must be a valid integer
number.
907 APC Unload-Switch Missed PAL 3
Pallet #3 did not return from the receiver to the APC in the allowable amount of time. This can be caused by the
chain switch block missing the limit switch, or from another mechanical problem, such as clutch slippage.
908 APC Unload-Switch Missed PAL 4
Pallet #4 did not return from the receiver to the APC in the allowable amount of time. This can be caused by the
chain switch block missing the limit switch, or from another mechanical problem, such as clutch slippage.
909 APC-Program Not Listed
The main program attempted to run a subprogram that is not listed in the Pallet Schedule Table for the loaded
pallet. To run the subprogram, enter the program name into the Program Name column of the Pallet Schedule
Table, for the pallet you want to operate on. Or, remove the M48 from the subprogram. Verify that the subpro-
gram and the pallet are compatible.
910 APC Program Conflict
The subprogram you are trying to run is not assigned to the loaded pallet. Another program is assigned to this
pallet in the Pallet Schedule Table. Either enter the program name that you want to run into the Program Name
column of the Pallet Status Table, or remove the M48 from the subprogram you want to use. Verify that the
subprogram and the pallet are compatible.
