NOTE A: When this control option condition occurs, the contacts close. Contacts are normally open when power
is off. To inverse this control option, press both the up and down arrow keys simultaneous ly until a d ash
is visible in front of the displayed control option. When an inverted control option condition occurs, the
contacts open.
B: When this control option condition occurs, the contacts open. Contacts are normally open when power is
off. To inverse this control option, press both the up and down arrow keys simultaneously until a dash is
visible in front of the displayed control option. W hen an inverted control option condition occurs, the
contacts close. Note that when an inverted control option is used, some conditions cannot be indicated,
including loss of power, some types of damage to the display/CPU board, or an open melter thermostat.
C: For PURBlue 4 melters, a reservoir-empty state produces a melter fault after several seconds. When the
fault occurs, the reservoir-empty output reverts back to its standard condition. In most cases, Nordson
Corporation recommends the use of control option 3 (Fault), which will indicate a reservoir-empty st ate
or any other condition that will stop production.
D: Control option 6 provides an output signal when a potential fault is detected. If control option 3 and 6 are
bothused,thenbothafaultoutputandanalertoutputsignalwillbepresentwhenthefaultLEDturnson.
E: Parameters 43 through 45 are reserved for t he outputs created when either the optional I/O expansion
card or optional I/O board is installed. Refer to Appendix B, Operating Parameters, for more information.
F: For wiring information, refer to the instruction sheet that is provided with the optional I/O expansion card
or analog I/O board.
