Page 4: Electrical Power Problems
Electrical Power Problems Controller display does NOT turn on. No heat in kiln. Is the kiln connected to the power? Make sure the kiln is plugged in. If the kiln’s wall circuit includes a power disconnect lever, make sure the lever is in the on position. -
Page 5: Controller Display Turns On. No Heat In Kiln
Controller Input Test Result: the controller is getting 20 - 24 volts If you find 20 - 24 volts, correct current is reaching the board from the trans- former. But since the board is not lighting up, it is probably defective. Try turning off the power to the kiln for ten seconds. -

Controller Power Output Test Is the controller sending voltage to the relays? Test OUTPUT with a voltmeter: Disconnect 1 UNPLUG the kiln/disconnect the power. Remove the 4 screws holding the controller board Power before opening kiln faceplate to the switch box. Lift faceplate out of box and let the board hang on the outside of the box with the switch box or back of the board facing you. - Page 7 Ramp-Hold Check to see if you have programmed a long hold time in one of the early segments. Do you see water dripping from the kiln or condensing on the case? Dripping water means the ceramic greenware is wet, which slows the kiln to a crawl.

Page 8: Some Elements Do Not Fire
Have you checked the kiln for loose connections? UNPLUG kiln/disconnect the power. Open the kiln’s switch box. Look for loose, corroded or discolored element connectors and wire terminals. They will appear dark, greenish-turquoise and sometimes white. Cut off over-heated wire terminals and crimp on new terminals. Remove the damaged element connector and inspect the element end. -
Page 9: Kiln Heats Unevenly
Kiln heats unevenly. How uneven is the temperature in the firing chamber? If only slightly uneven: Load more ware in the hot section and less ware in the cool section. This balances the load. If very uneven: Check for burned out elements and bad relays. See “Some elements do not fire,” page 8. Does the kiln have a power connection fuse box? This fuse box is used only on high amperage kilns such as the Viking-24 &... -

Controller temperature using the methods below. Use witness cones in every firing. Keep a record of every firing. Blank firing records are available from Paragon. DTC 1000 Cone-Fire: Use cone offset to adjust the temperature for each individual cone. Or use thermocouple offset to adjust the temperature for all the cones. -
Page 12: The Display Remains Stuck
Has the thermocouple been installed correctly? Is the thermocouple worn out? Make sure the thermocouple remains out of contact with the kiln case or anything metallic. Position thermocouple lead wires away from other wires inside the switch box. Though protected by insulation, the thermocouple wires are sensitive to electromagnetic waves from other wires. -

Error Messages PF or ErrP during firing. Have you had a power failure? PF or ErrP due to power failure. alternates with the temperature display during firing: this means the power went off for a moment dur- ing firing. Then firing resumed. To go back to a normal temperature display, press ENTER Steady , no temperature display: the firing has been interrupted by a longer power failure. -

Page 16: Err B
Err B Is room temperature unusually high? appears when the temperature at the circuit board is above 250°F. Open windows and use a fan to circulate Err B 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.
