The ETS Junction Box with oil pressure protection (OP), water temperature protection (WT), and overspeed protection (OS) that does not require a switchgear is a system that has full protection. The system has a junction box arrangement that is designed to monitor four functions:
Engine overspeed
Crank termination
Oil pressure
Coolant temperatureThe junction box includes the following components:
Electronic speed switch (ESS) (2)
Start/stop switch (SSS) (18) and (16)
Slave relay (SR1) (13)
Slave relay (SR2) (if equipped) with an air shutoff solenoid (ASOS) (14)
Oil pressure switch (OPS1) (18) and (20)
Oil pressure switch (OPS2) that is only in 3500 Engines (22)
Emergency stop switch (ES) (8)
Time delay relay (TD) (9) The components that are listed below operate with the junction box. The components are also mounted on the engine.
Fuel shutoff solenoid (FSOS)
Air shutoff solenoid (ASOS)
Water temperature switch (WTS)The following components must remain de-energized in order for the engine to run with the ETS electric protection system.
Slave relay (SR1)
Slave relay (SR2) (if equipped)
Fuel solenoid (FS)
Air shutoff solenoid (ASOS)Electrical Schematics And Wiring Diagrams
This manual contains the point-to-point wiring diagrams for the complete electric protection system and the junction box. Four types of electrical schematics for each electric protection system arrangement are shown in this service manual.
