GENERAL
The PRINT keys allow the operator to obtain a remote
print-out of real-time system operating data and a print-
out of system data at the “instant of the fault” on the last
three faults which occurred on the chiller.
If a remote printer is not being used, or the desire is to
obtain data locally at the panel, the same keys allow
access to identical fault data. Identical and additional
real-time information is available by using a combination
of the PRINT keys and the other keys on the keypad.
An explanation of the use of the keys for remote printer
or local data retrieval will follow. An optional printer (Page
77) will be required for remote printout.

printer. As the data is transmitted, it will be erased from
memory.
A sample printout is shown in Fig. 20.
