01 N IMPROPER MODE SELECTION
The PM module expects to see one of the allowable press
modes (off, inch, microĆinch, single, continuous, within 0.1 sec's
after swingarm power is sealed in, and will only allow one mode
at any given time.
Check selector switch wiring in figure 6.10 and operation.
Check wiring to swingĆarm. Check I/O module for correct
operation.
02 N ALL STATIONS BYPASSED
In the single stroke or continuous mode, the PM will not allow the
press to cycle if all operator run stations are bypassed. At least
one station must be present. Inch and microĆinch modes will
operate with all run stations bypassed.
Check station wiring in figures 6.11 and 6.12. Check
swingĆarm wiring and I/O module for proper operation.
03 N SHAFT NOT AT TOP. CAN NOT ENTER SINGLE OR
CONTINUOUS MODE
The PM is selected to go into the single or continuous mode, but
the cam switches, which indicate shaft position, are telling the

the press will stop if that input goes off.
Check feedback contact and wiring in figure 6.10. Check
swingĆarm wiring and I/O module for proper operation.
06 N ACAM OPEN, PREVENTING ENTRY INTO SINGLE OR
CONTINUOUS MODE.
Check wiring of ACAM in figure 6.9 and check ACAM
