Print Key

The PRINT key allows the operator to obtain a printout 
of real-time system operating data or a history printout 
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 system 
operating parameters. When the OPER DATA key is 
pressed, a snapshot will be taken of system operating 
conditions and panel programming selections. This data 
will be temporarily stored in memory and transmission 
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.)
