SECTION 2 – OPTIVIEW CONTROL CENTER
signal is applied to both the lead and lag compressor
vanes until the lowest motor current is greater than or
equal to 80% of the highest motor current. The load
limit will remain in effect until the lag compressor is
shutdown, whereupon the message is cleared.
“WARNING – ANTI SURGE – SURGE COUNT
EXCEEDED”
This warning applies to dual compressor operation
only. The Surge Window Count exceeded the Count
Limit while both compressors were running. To pre-
vent further surging, a soft shutdown is performed on
the lag compressor when this warning is displayed.
This message will be displayed until manually cleared
with the WARNING RESET key in Operator (or high-
er) Access Level.
“WARNING – COMPRESSOR #1 LOCKED
OUT”
Compressor #1 is inhibited from starting because it has
been placed in service lockout. This is performed on
the Compressor Capacity Cycling Screen.
“WARNING – COMPRESSOR #2 LOCKED
OUT”
Compressor #2 is inhibited from starting because it has
been placed in service lockout. This is performed on
the Compressor Capacity Cycling Screen.
“WARNING – OIL PUMP #1 – SEAL LUBRICA-
TION - LOW PRESSURE”
A minimum of 15 PSID of oil pressure was not achieved
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 #1. 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
Lube #1 is disabled on OIL PUMP 1 Screen or com-
pressor #1 enters the prelube state.
“WARNING – OIL PUMP #2 – SEAL LUBRICA-
TION - LOW PRESSURE”
A minimum of 15 PSID of oil pressure was not achieved
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
Lube #2 is disabled on OIL PUMP 2 Screen or com-
pressor #1 enters the prelube state.
“WARNING – LOW OIL LEVEL”
Displayed if the oil level in the oil sump is less than the
Minimum Oil Level as shown below. It will automati-
cally clear when the level is greater than the Minimum
Oil Level.

eration and only if the Surge Protection SHUTDOWN
Setpoint is disabled. The Surge Window Count has

pressor operation. This message can be cleared with
the Warning Reset key in Operator access level (or
higher) after the Surge Window Count is less than the
Count Limit.
