TROUBLE

CHECKOUT PROCEDURE & INFORMATION

...cont.

Grain High Light (auto resets after cooling):

LH grain column hi-limit switch has reached 210°F
RH grain column hi-limit switch has reached 210°F

A. Grain has over dried due to:

unload auger off
meter roll speed set too low
moisture control temperature set too high
grain column plugged

B. Failed grain hi-limit switch

Burner Lockout (Manual reset)
Flame was not sensed for 5-15 sec.
A.

Burner failed to ignite
main shutoff valve was not opened in 5-15 sec. time allowed
minimum fire set too low
hand valves closed
insufficient fuel supply
failed or dirty spark plug
failed or dirty flame rod
failed liquid LP solenoid valve
vapor hi-limit sensor reached 220°F and has not cooled down
failed ignition transformer

B.

Burner flame has gone out
minimum fire set too low
insufficient fuel supply
plenum pressure switch set has sensed low pressure
failed, dirty or improperly positioned flame rod
failed liquid LP solenoid valve
vapor hi-limit sensor reached 220°F and has closed liquid solenoid

NOTE: A flame failure will cause the Burner Lockout Indicator to light. If the unload auger is ener-
gized, the dryer unload will stop and the dryer will shut down after a three-minute time period due to a
meter roll monitor time-out.  The Meter Roll Monitor indicator light will also come on with the lockout
light but should be ignored in this situation.  If the Unload Auger switch is OFF, the dryer control cir-
cuit will not be shut down due to a burner lockout.  The Flame Safeguard control must be manually
reset before re-ignition is allowed.

UNMONITORED SAFETY SHUTDOWN DEVICES

Unload auger overload relay
Load auger overload relay
Fan overload relay
SCR overload relay

Overload relay has opened (manual reset required)

A. Amperage draw too high on motor

low voltage
motor load too high
loose overload heater elements screws
loose power wires
partially shorted motor wires
failed motor

B. Overload improperly set
C. Failed relay
D. Relay has not been manually reset
E. Low voltage
F. Relay set too long on part-wind starter (set 1 to 2 seconds)

Discharge Shutoff Switch
Unload auger discharge switch has opened (may require cleaning grain from under DSS door to

reset)

A. Auxiliary unload equipment has failed or overloaded
B. Discharge door is not seated properly
C. Discharge proximity switch failed

Top Auger Will Not Start

1.

Check that top auger circuit breaker is turned ON, also that control circuit is energized and

LOAD AUGER SWITCH is set to ON or AUTO position.
2. 

Check position of upper auger paddle and its switch box - paddle must be "down" with switch

box horizontal to start auger.  Paddle should rotate freely without "sticking."
3.

Inspect for secure mounting and wiring of mercury switches in terminal box on top auger paddle

switch shaft.  Include check for defective mercury switch. When calling for grain, both mercury switch-
es should be closed and passing 120V to top auger contactor coil.
