The audible onboard alarm may be silenced by pressing the “SILENCE”
control on the front panel of the Main Control Unit. THIS ACTION DOES
NOT INDICATE THAT THE ISSUE CAUSING THE ELEVATED
TEMPERATURE HAS BEEN FIXED.
If the shaft seal temperature remains above 50° C (122° F) the yellow
LED(s) will continue to flash and the alarm will activate again. After
resolving the issue causing the elevated temperature warning, the
“NORMAL”green status LED(s) will illuminate.

Critical Alert State
A Critical Alert is indicated by the Red LED(s) flashing rapidly. The
audible alarm and external siren (if equipped) will sound with every flash.
This indicates that the shaft seal temperature is above 70° C (158° F),
and that ACTION MUST BE TAKEN IMMEDIATELY TO RESOLVE THE
PROBLEM.
The Critical alert audible alarm and external siren may be silenced via the
control on the Main Control Unit front panel. Once the problem has been
solved and the shaft seal begins to cool down, the Warning State may
temporarily occur. Once the shaft seal temperature goes below 50° C
(122° F), the green LED(s) will illuminate and audible alarms will stop.

System Operation
There are three states of operation: “NORMAL, WARNING and CRITICAL”
which are indicated by the LEDs on the front panels of each unit in
operation. For twin engine configurations the Port and Starboard states are
independent of each other such that one may be normal when the other
indicates an overheating condition.
Normal Operation
Normal state is indicated by the Green LED(s) being illuminated when the
engines are running. This indicates that the system is operating with the
shaft seal temperature below 50° C (122° F).
Warning State
Warning State is indicated by the Yellow LED(s) flashing slowly (every 4
to 5 seconds). The audible alarm will sound with every flash. This
indicates that the shaft seal temperature is above 50° C (122° F) but less
than 70° C (158° F).
Steady Green LEDs- indicate Normal Operation
Slowly Flashing Yellow LEDs with Alarm Sound- indicate WARNING condition
