Error
Code
Description Causes Correction
E- 0
Software Error.
Caused by hardware or electrical noise, can be caused
by electrical spikes, surges, or arcing across the relay
Recheck the selected program, and
reprogram if necessary.
E- 1
The temperature is increasing less than 12 degrees per hour during a ramp segment,
where the temperature is programmed to increase. This slow rate must persist for 22.5
minutes before the error is displayed
Worn or old heating elements
Low voltage to the kiln
A broken heating element or faulty relay
Burned or broken wires to the elements or relays
Electrical noise
Check elements.
Check Relays
Use VOLT Menu feature to check voltage.
E- 2
During a hold segment the temperature rises to greater than 50 degrees above the
hold temperature which was set. The temperature must stay 50 degrees above this set
temperature for 18 seconds before the error is displayed.
Stuck relay.
If only one section (or relay) remains on
then it is a stuck relay. Turn of breaker to
shutoff power to the kiln.
E- 3
During a hold segment the temperature is more than 50 degrees below the hold
temperature which was set. The temperature must stay 50 degrees below this set
temperature for 18 seconds before the error is displayed.
Opening the door or lid of the kiln.
Relay or element failed during firing.
Check relay.
Check elements.
E- 4
The firing is in a ramp segment where the temperature is programmed to decrease
and temperature is more than 50 degrees above the previous hold temperature. The
temperature must remain 50 degrees about the hold temperature for 18 seconds before
the error is displayed. E- 4 is the same as E- 2 except that E- 4 occurs during a ramp
phase rather than a HOLD
Stuck relay
Skipped step feature
Check relay
If E- 4 occurs when skipping a ramp phase,
press a key to clear the error.
Allow the kiln to cool to within 50 degrees
of the next hold temperature.
Restart kiln and skip steps until you get to
the segment you want.
E- 5
The temperature is more than 50 degrees below the local set-point temperature during a
ramp segment where the temperature is programmed to decrease. The temperature must
stay 50 degrees below this set temperature for 18 seconds before the error is displayed.
Open door or lid.
Bad elements.
Bad relay.
Check elements.
Check relay.
E- 6
A Negative temperature is displayed. This generally indicates the thermocouple is
connected incorrectly. To correct this situation, ensure the red and yellow wires are
connected correctly to the controller and at all junctions. You can identify the red lead
on an unmarked thermocouple with a magnet because a magnet will be attracted to the
red lead.
Using the kiln in temperatures below 0 degrees
°
F
(17 degrees
°
C)
Thermocouple (T/C) connected backwards, red and
yellow leads reversed.
Board has been damaged by static electricity or ESD
(electro static discharge)
Check T/C to make sure it is
connected properly.
Do T/C bypass test, if temperature reading
is still negative, the board has been
damaged and needs service.
