SECTION 2 - OPTIVIEW OPERATION
PROGRAMMABLE
Login
Access Level Required: VIEW
The OptiView panel restricts certain operations based
on password entry by the operator. This key allows the
operator to login under a unique user name (as pro-
grammed) and access level. Users logged in under
higher access levels may perform any actions permit-
ted by lower access levels.
Logout
Access Level Required: OPERATOR
When logged in at any level other than “View”, this
key appears on the OptiView display. Pressing this
key will return the access level to “View”. After any
setpoint changes are made, the operator should press
the “Logout” key.
Print
Access Level Required: VIEW
This key provides a printout of the user selected condi-
tions at the time the key is pressed. The “History” page
provides further reporting capability (See “History”
below). This option will not be present if the chiller is
presently configured to log any incoming adaptive ca-
pacity control map points (See the Adaptive Capacity
Control Details screen).
Message Clear
Access Level Required: SERVICE
When the control center detects certain safety or cy-
cling conditions and the chiller shuts down, the main
status display on the display will show a message in-
dicating the cause of the shutdown. Pressing this key
while logged in at the appropriate access level clears
the message, provided the condition no longer exists.
Warning Reset
Access Level Required: OPERATOR
Use of this key acknowledges a warning condition and
resets the message display associated with the condi-
tion.
Soft Shutdown
Access Level Required: OPERATOR
This key, available only when the compressor is run-
ning, initiates a “Soft Shutdown”. A soft shutdown ful-
ly closes the pre-rotation vanes prior to shutting down
the compressor, reducing bearing wear by eliminating
compressor backspin at shutdown. While the vanes
are closing, the System Status line displays “VANES
CLOSING BEFORE SHUTDOWN”. When the Vane
Motor Switch (VMS) closes, indicating the vanes have
fully closed (or 3.5 minutes have elapsed, whichever
occurs first), the run signal is removed from the com-
pressor motor starter and a “System Coastdown” is
performed.
While the vanes are closing, if a “Local Stop” is initi-
ated by the compressor switch or a fault occurs, the
chiller will immediately enter system coastdown.
This chiller will not enter a system coastdown if one
of the following faults occur: “Leaving Chilled Liquid
Temp – Low Temperature”, “Remote Stop”, “Multi-
Unit Cycling – Contacts Open”, “System Cycling –
Contacts Open” or “Control Panel – Schedule”
To restart the chiller after an operator-initiated soft
shutdown, place the compressor switch in the “Stop/
Reset” position ( O ) and then the “Start” position (◄).
