Modes of OperationModes of Operation
• Normal Mode• Alarm Mode• Shutdown Mode• Service Mode
Engine Starting SequenceEngine Starting Sequence
Start or remote signal
Check sys for faults, engine is not already running, not in service mode
Activate SMR, FCR
Note: -FCR energize to run (K4, K5, K7) or to stop (K4, K5) -The relay status on the relay status indicators of the lower display. K1, K3, K5, K7 for ETR ; K1, K3, K5 for ETS
Deactivate SMR
-rpm=400& Activate CTR
Activate EG relay – oil press=set point
for low oil press.
Engine Stopping SequenceEngine Stopping Sequence
Stop or remote signal
Check sys for faults, begin the cool down time, and activate the spare output (if programmed)
Deactivate RR & EGR
oil press<set point for low oil press.
* Note: The relay status on the relay status indicators of the lower display. all relays are Off except on ETS K7 indicator remain On for 70 sec after 0 rpm and oil press is also 0
Deactivate CTR
(RPM = 0)
*Deactivate 0r activate
