in the first 30 seconds of the seal lubrication cycle (or
it dropped below this value during the remaining 90
seconds of the cycle) for compressor #2. This message
must be manually cleared using the WARNING RE-
SET key in Service access level (or higher). As soon as
the message is cleared, another seal lubrication will be
attempted. The message will also be cleared if Standby

“WARNING – SURGE PROTECTION - EXCESS
SURGE DETECTED”
(Applies only to single compressor operation and
only if the Surge Protection SHUTDOWN Setpoint
is disabled) The Surge Window Count has exceeded
the Count Limit setpoint during single compressor op-
eration. This message can be cleared with the Warning
Reset key in Operator access level (or higher) after the
Surge Window Count is < the Count Limit.
“WARNING – SURGE PROTECTION – EXCESS
SURGE LIMIT”
(Applies to single compressor operation only and only
if the Surge Protection EXTENDED RUN Setpoint is
enabled) The chiller is operating in a Surge Protec-
tion Extended Run period because the Surge Window
Count has exceeded the Count Limit setpoint during
single compressor operation. When the Surge Window
Count exceeds the Count Limit setpoint, a 10 minute
Extended Run period is initiated. During this period,
the Pre-rotation Vanes are driven closed. At the end
of the 10 minute period, if the Surge Window Count is
< the Count Limit, this message is cleared and Vanes
are allowed to load. Otherwise, another 10 minute Ex-
tended Run period is initiated.
