Print Key
The PRINT key allows the operator to obtain a printout
of real-time system operating data or a history print-
out of system data at the "instant of the fault" on the
last six faults which occurred on the unit. An optional
printer is required for the printout.
Operating Data Printout
Pressing the PRINT key and then OPER DATA key
allows the operator to obtain a printout of current sys-
tem operating parameters. When the OPER DATA key
is pressed, a snapshot will be taken of system operat-
ing conditions and panel programming selections. This
data will be temporarily stored in memory and trans-
mission of this data will begin to the printer. A sample
Operating Data printout is shown below. (Note: Not all
values are printed for all models.)
