ELECTRIC PROTECTIVE SYSTEM SCHEMATIC
NOTE A: Terminal strip jumpers between terminals TS17 & TS18 and TS19 & TS20 are not required when alarms are used for low oil pressure and high water temperature.
NOTE B: The terminal strip wire between terminals TS26 & TS27 is in the wiring harness when a 3161, UG8D or UG8L governor is installed. When a 2301 governor is used, no wire is required; also, no fuel shutoff solenoid is used between TS6 & TS12.
NOTE C: This wire is provided by customer if electric starter motor(s) are not used.

CUSTOMER WIRING WITH ELECTRIC PROTECTIVE SYSTEM (NOTE A)NOTE A: Wire, cable and components shown with dotted lines are to be added by customer. See wire and cable gage charts for size selection.NOTE B: Do not use remote emergency switch for normal engine shutdown. The use of emergency switch requires manual reset of air shut-off at top of air inlet housing.NOTE C: Caterpillar alarm and prealarm contacts are rated for a maximum of 3 amps inductive at the charging system voltage.NOTE D: Switch to be a single pole, normally open switch (may be latching if desired) with a minimum contact rating of .5 amp inductive at the charging system voltage.NOTE E: Switch to be a single pole, normally open switch (may be latching if desired) with a minimum contact rating of 1 amp inductive at the charging system voltage.NOTE F: Magnetic pick-up and oil pressure switch to be wired to electric governor control (Woodward 2301) with a two conductor shielded cable (Belden Corp. type 8780 or equivalent). Shields are to be grounded at electric governor control grounding stud. Each shield should not have more than one ground connection.NOTE G: Woodward 2301 Electric Governor Control terminal identification chart:
