Note:
As shown in the graphics on the following page the PM4, 8 and 9 controls will include two "EZ" buttons (EZ1
and EZ2). The button identified as EZ1 is equivalent to the EZ button described above where the button identi-
fied as EZ2 has no functionality. Assuming the issue that caused the limit to trip has been rectified pushing
the EZ1 will reset the limit as described for the Reset button above. All other buttons found on these controls,
maintain the same functionality as described above for the 16 th DIN.
