E- 0
Software Error.
Caused by hardware or electrical noise, can be
caused by electrical spikes, surges, or arcing.
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.
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.
