CORRECTIVE
ACTION:
A1.
IF VOLTAGE IS PRESENT ON TERMINAL #39 (120 VOLTS),
TURN LOAD SWITCH (SW4) TO "ON" THEN CHECK FOR
VOLTAGE ON TERMINAL #46. IF VOLTAGE IS NOT PRESENT
THE LOAD SWITCH (SW4) IS DEFECTIVE, REPLACE.
A2.
IF VOLTAGE IS PRESENT ON TERMINAL #46 (120 VOLTS),
THEN CHECK FOR VOLTAGE ON TERMINAL #47. NOTE: MAKE
SURE HIGH / LOW GRAIN MONITOR PADDLE IS HANGING IN
THE DOWN POSITION. IF VOLTAGE IS NOT PRESENT THE
SWITCH (LOW) IS DEFECTIVE, REPLACE.
A3.
IF VOLTAGE IS PRESENT ON TERMINAL #47 (120 VOLTS),
THE GRAIN LOADING LIGHT (DS12) IS DEFECTIVE,
REPLACE.
B1.
IF LOAD AUGER STARTER (S5) DOES NOT PULL-IN AND
VOLTAGE IS PRESENT AT LOAD SIDE OF COIL, THE
HOLDING COIL IS DEFECTIVE, REPLACE.
B2.
IF LOAD AUGER STARTER (S5) DOES PULL-IN, CHECK LOAD
SIDE OF INTERLOCK (SW19) ON LOAD AUGER STARTER (S5)
FOR PRESENCE OF VOLTAGE (120 VOLTS). IF VOLTAGE IS
PRESENT AT LOAD SIDE OF INTERLOCK (SW19), CHECK
OPPOSITE SIDE OF INTERLOCK (SW19). IF NO POWER IS
PRESENT, THE INTERLOCK (SW19) IS DEFECTIVE,
REPLACE.
B3.
IF AUXILIARY LOAD STARTER (S6) DOES NOT PULL-IN AND
VOLTAGE IS PRESENT AT LOAD SIDE OF COIL, THE
HOLDING COIL IS DEFECTIVE, REPLACE.
C.
OVERLOADS ON LOAD AUGER AND/OR AUXILIARY LOAD
STARTERS (S5, S6) MAY HAVE TRIPPED FROM A MOTOR
DRAWING HIGH AMPERAGE. DETERMINE WHICH ONE IS OPEN.
RESET DEFECTIVE OVERLOAD. IT WILL BE NECESSARY TO
DETERMINE IF A SHORT CIRCUIT OR EXCESSIVE OVERLOAD
CONDITION EXISTS IN THIS ISOLATED SYSTEM AND WHAT
CORRECTIVE STEPS NEED TO BE TAKEN TO RESOLVE THIS
CONDITION. OTHER POSSIBLE CAUSES COULD BE (1) BAD
MOTOR, REPLACE. (2) JAMMED AUXILIARY LOAD SYSTEM,
CORRECT. (3) LOOSE WIRING CONNECTIONS ON TERMINALS,
TIGHTEN. (4) DEFECTIVE OVERLOAD, REPLACE. (5)
IMPROPER ADJUSTMENT OF HIGH / LOW GRAIN MONITOR,
(AUGER ONLY) ADJUST TILT SWITCHES (LOW AND/OR HIGH)
IN HIGH / LOW GRAIN MONITOR BOX. ADJUST LOW TILT
SWITCH SO THAT THE LOAD SYSTEM WILL TURN "ON" JUST
BEFORE THE GRAIN PADDLE SWINGS TO A STRAIGHT DOWN
POSITION. ADJUST HIGH TILT SWITCH SO THAT THE LOAD
SYSTEM WILL TURN "OFF" WHEN THE GRAIN PUSHES THE
PADDLE FORWARD TO 40° ANGLE.
D1.
TRASH AND PLUGGING PROBLEM - CHECK LOW GRAIN
SWITCH(S) (SW9, SW10) FOR TRASH BUILDUP BEHIND
PADDLE.
D2A. FRONT LOW GRAIN SWITCH (SW9). IF VOLTAGE (120
VOLTS) IS PRESENT ON TERMINAL #35 CHECK VOLTAGE ON
