Turning Off Error Codes (ErCd)

The DTC 1000 uses error codes to alert you to firing prob-
lems. In certain applications, it may be desirable to turn off
some of the error codes.
For instance, error code
rises slower than 12°F/12°C per hour. (In Ramp-Hold, the
temperature is also below the programmed temperature.)

Trouble-Shooting & Maintenance
Furnace or Kiln Wiring Diagram
Your wiring diagram will show you how the controller, re-
lays, transformer and heating elements are connected. It will
aid you in tracking down problems. If you need a replacement
diagram, call us.
Protecting the Controller From Static
Static electricity can damage the controller. Before han-
dling the board, touch a grounded object. When shipping the
controller for repairs, do not pack in bubble wrap or styrofoam
peanuts. These materials can build up a static charge. Instead,
use anti-static foam or even newspaper.
Element Glow Test: A Quick Test
Of Elements and Relays
1 The kiln should be empty. Close the lid or door.
2 In Ramp-Hold, fire at a rate of 9999 to 500°F/260°C.
While the kiln is firing, study your kiln's wiring dia-
gram. It will show which elements are wired to each re-
lay.
3 At around 400°F/204°C, carefully lift the lid or open the
door slightly until you can see the glowing elements.
CAUTION:
Use a protective glove. Keep your face
well away from the firing chamber. Do not reach inside
the chamber. DO NOT TOUCH THE ELEMENTS
WITH ANYTHING. Lift the lid for only a moment, then
close it.
The center elements in most 7, 8, 10 and 12 sided kilns will
not glow brightly, but there should be a faint redness. It may be
easier to see the elements by turning off the room lights.

Test result: All the elements for one relay remain dark.
The relay is probably defective.
Test result: One element remains dark, others glow.
If more than one element is wired to the relay, the dark ele-
ment is probably burned out. The problem is not the relay.
On completion of firing, the display will show firing time in
hours/minutes. Firing time will help you or your repair techni-
cian determine if the kiln is firing fast enough.
How to Remove Controller
SWITCH BOX WARNING:
UNPLUG kiln or furnace be-
fore opening switch box or re-
moving faceplate. Touching a
live connection inside switch
box could be fatal. Kiln must
be unplugged anytime switch
box is removed from kiln.
UNPLUG the kiln (or TnF
II). Remove the four screws hold-
ing the faceplate to the switch
box.
TnF II owners: UNPLUG the TnF II from the wall outlet
whenever these instructions say to unplug the kiln.
Removing Controller for Voltmeter Check
When checking controller board with a voltmeter
multitester, remove only controller faceplate and not the kiln
switch box. Before removing controller board, UNPLUG the
kiln. Then let the controller board hang on the switch box with
the back of the board facing you. Plug the kiln back in before
testing the board. The reason to unplug the kiln before you re-
