Understanding The Fault Screens - Cumberland Stove Works OMMF3500 Operator's Manual

UNDERSTANDING THE FAULT SCREENS
STARTUP CHECK
EXHAUST OFF
Problem: The ON key has been pushed for start and the
POV (Proof of Vacuum) switch has not detected vacuum.
There is a 15 second delay waiting for the start cycle to
continue before the screen [START CHECk EXHAUST
RUNNING] appears.
Remedy: Check for open door or gasket leaks. Restart
the stove.
NO FUEL SELECTED
USE MODE KEY
Problem: The screen waits for you to push the MODE
key. If any other key is pushed on the TRI-X controller,
the display will alternate between [NO FUEL SELECTED
USE MODE kEY] and [SELECT FUEL TYPE USE MODE
kEY].
Remedy: Push MODE key and select the type of fuel in
use.
HOPPER OPEN
FEED AUGER OFF
Problem: The hopper door has an interlock that stops the
auger from operating. This is to assure that no injuries
occur with the hopper open.
Remedy: Close hopper door.
note: if the door remains open for an extended period
of time the fire will go out. Closing the door promptly
will eliminate the need to start the fire over.
COOL DOWN MODE
LOSS OF FIRE/OFF
PUSH OFF/ON TO
RESTART STOVE
Problem: These two screens are used to instruct you to
push the OFF/ON key because the fire has gone out. The
common reasons for this are:
• The fuel selected during the startup was not correct
and the feed rates are usually too much to sustain a
flame.
800-345-6007
• The door was open for more than five minutes.
• The hopper has been emptied of fuel.
Remedy: Wait a minimum of 30 seconds, push OFF key
until [SELECT FUEL TYPE USE MODE kEY] appears.
The normal start sequence will begin.
Problem: This message will be displayed if the door is
opened or the vacuum in the burn chamber is lost because
of a leak or the ash pan is removed for a long period of
time.
Remedy: TRI-X controller will instruct you when to push
the ON key to return to normal operation.
note: if this problem persists, check the door seals
are in good condition on both the ash door and the
glass door.
COOL DOWN MODE
OVERTEMP SWITCH
Problem: The temperature of the exhaust has exceeded
a safe operating level and the stove will shutdown when it
has cooled to a safe level.
Remedy: The first action that should be taken when
seeing the alternating screens is to check all areas around
the stove for excessive heat. Causes for exceeding the
overtemp limit are as follows:
• Circulating air filter plugged.
• Excessive room temperature.
• Plugged circulating fan.
• Faulty circulating fan.
• Dirty heat exchanger.
