Err B
I
Is room temperature unusually high?
Err B appears when the temperature at the circuit board is above 250°F. Open windows and use a fan to circulate
air. If you have more than one kiln in the room, place them farther apart. Never allow the firing room temperature to
exceed 110°F/43°C. (Measure room temperature 3’ away from the kiln.)
I
Defective controller
If Err B appears when the room temperature is normal, return the controller.
Err d
Errd appears when the temperature is more than 100°F too high during a heating-up ramp.
I
Stuck relay.
Test relays. See “Err 2,” page 14.
I
Did you fire to a low temperature?
If you fire to a low temperature, such as 300°F/149°C, Errd may appear due to a temperature over-shoot. Fire at a
slower rate.
I
Multiple zone kilns.
On a multiple zone kiln, Errd usually means the thermocouples or relays are connected to the wrong controller ter
-
minals. Thus, a thermocouple is turning on the elements to the wrong zone. For instance, if the top thermocouple
turns on the bottom elements, the kiln will fire out of balance. When a zone gets over 100°F hotter than the pro-
grammed temperature, Errd appears.
To solve the problem, compare the switch box wiring with the wiring diagram for your kiln. Trace thermocouple
and relay lead wires to the back of the DTC 1000 board. Each thermocouple should be matched to the correct relay.
See DTC 1000 diagram, page 1.
Kiln Thermocouple Relay
Section Connections Connection
Top #13 & #12 #2
Middle #11 & #10 #3
Bottom #9 & #8 #4
Two zone kilns: do not use thermocouple connections #9 and #8 and relay connection #4.
I
Does your kiln have a door or lid switch?
If Errd appears when you open or close the lid, replace the door/lid switch.
Err E, Err H, Err t
I
Defective controller.
Err -
I
Power loss during processing.
There was a power loss to the controller while sending data to a memory chip. Use “Program Review” to be sure
your program is still in memory. If you get an Err - regularly, the controller may need servicing.
StUC
I
Stuck key or solder joint failure.
Return the controller for servicing.
