PRINT KEY
Print Key Operation
The PRINT key is used to initiate a printout of current
operating data (real time data), a complete history printout
of all history (fault) buffers, a printout of all normal
shutdowns (compressor cycling, chiller shutdown, etc.)
or history (fault) data printout of a specific fault. History
Buffer 1 will always be the most recent fault history
printout. Printing may also be canceled by selecting the
CANCEL PRINTING option. The following message is
displayed when the PRINT key is pressed.

History Data Printout
History printouts, when selected, provide stored data
relating to all specific system and chiller operating
conditions at the time of the fault, regardless of whether
a lockout occurred. History information is stored in
battery-backed memory on the Chiller Control Board
and is not affected by power failures or resetting of
faults. Whenever a fault of any type occurs, all system
operating data is stored in battery-backed memory at the
instant of the fault.
The most recent fault will always be stored as HISTORY
BUFFER #1.
SYSTEM SWITCHES KEY
System Switches Key Operation
The SYSTEM SWITCHES key allows the operator to
turn individual systems ON and OFF. Safety lockouts
are also reset by selecting the respective system switch
RESET. When the SYSTEM SWITCHES key is pressed,
the following message will appear:
SYSTEM SWITCHES SYS X ON/OFF/RESET
< > = SYSTEM OFF
The display indicates the respective system and it’s ON/
OFF / RESET switch status. The ▲▼ (ARROW) keys
allow scrolling to the next and previous system switch
(System 1 and 2).
The ◄ (LEFT ARROW) or ► (RIGHT ARROW) keys
allow scrolling through the choices of: SYSTEM OFF
(default), SYSTEM ON, RESET (LOCKOUT). The
switch selection is accepted into memory by pressing the
(ENTER) key.
When the “RESET” selection is made and accepted, it
will not change the position of the switch (either ON or
OFF).
Whenever possible, except in emergencies,
always use the associated system switch to
turn off a compressor, which allows the
compressors to go through a controlled
shutdown. Avoid using the "UNIT" switch
to turn off the compressors.
