Obtaining a Print-out
A print-out of current operating data may be obtained by
pressing the OPER DATA key. A snapshot will be taken
by the micro of current operating conditions. These con-
ditions will be stored in memory until they can be trans-
mitted to the printer and printed. A sample print-out is
shown in Fig. 20 on page 55.
A print-out of the fault shut-down history may be ob-
tained by pressing the HISTORY key. A print-out show-
ing the last 3 faults with all system conditions at the time
of the fault will be transmitted. A sample print-out is
shown in Fig. 21 on page 56.
An automatic print-out will be sent to the printer when-
ever the chiller shuts down on a fault, regardless of
whether the fault causes a system or the entire chiller to
lockout or whether restart is permitted. This is the same
print-out that is obtained when the OPER DATA Key is
pressed, however it will be a snap-shot of system operat-
ing conditions at the instant fault occurred. Additionally,
the Status indication that is noted in the print-out will
note the specific fault that occurred.
Using Other Printers
Control codes vary from printer to printer. This will result
in unusual formatting of printed data from many printers.
In addition, “handshaking” lines and “handshaking” se-
quence will differ between printers. This makes the
equipment susceptible to operation problems or mis-
wiring which may cause damage to the printer or the
Microprocessor Board. YORK assumes no responsibil-
ity for assistance or damage in the use of non-specified
printers.
Warranty
YORK assumes no warranty responsibility in the use of
the printer. This includes damages to the printer and the
Microprocessor Boards or chiller operation problems
which may result.
