Figure 2 shows a typical wiring diagram for machine guards. As the dia-
gram illustrates, the machine guard switch should be wired to pins 1 and 2.
When the machine guard switches are open, the contacts to those pins will
open, and an Operator Intervention Message (OIM) message will appear on
the MILLPWR screen.
Note:
If guards are not used then pin 1 and pin 2 of J2 must be
jumpered.
Low Oil is a safety feature that will, under certain conditions, stop program
functions when the lubrication pump supply reaches a certain minimum level
of oil. The normally closed low oil switch should be wired to pins 3 and 4.
When the low oil switch opens:
1) Find Home, Move Table, Single Cycle and all program functions
cannot be initiated.
If the low oil feature activates during
these operations:
1) Find Home and Move Table functions will be aborted.
2) Single Cycle and program functions will complete their current
path and then pause.
Note:
If a low oil sensor is not used, then pins 3 and 4 must be
jumpered.
