“Thermocouple” inputs too noisy
AC power wires may be too close to the thermocouple lead wires or the electronics board. Try
isolating the AC power wires away from the thermocouple lead wires or the electronics board.When
a PLOG error message is displayed, the controller is inoperable. The normal way to clear the PLOG
error is to push the ENTER key. If this does not clear the error condition then the controller
requires a special two-button reset. Perform the “Reset Parameters to Factory Default” sequence
explained below to clear a PLOG error message that is not be cleared by simply pressing ENTER to
acknowledge the error code.
CAUTION:
Resetting all parameters to factory default setting may change current controller configurations,
so these will have to be reset by the user through Level 2 Options. It is important to be sure that Thermocouple
Type is correct, especially if a Type S platinum thermocouple is being used. (Version 0030 and below defaults
to Type K thermocouple. Version 0031 and above defaults to Type S thermocouple)
Reset Parameters to Factory Default
1.
Turn off power to the AutoFire®
Controller.
(When turned off, the controller will have no display).
2.
Press [Stop/Start] and [Options] simultaneously while then turning on power to the controller. Keep
the keys pressed until the audible beep turns off, then release both keys.
3.
Check to see that controller is in the Idle mode and is alternating Idle with current kiln temperature.
4.
After resetting the controller, some parameters may need to be reset manually to match the desired kiln
configuration. Here is a list of defaults of the controller after a two-button reset:
Parameter:
Default:
Possible Action:
RS485 Node Id:
0
Set from 0 to 15
TC Type:
S (version 31 and higher)
Set to K or N
Temperature Units:
Fahrenheit (
°
F)
Set to
°
C
Number of Relays:

Use Level 2 Options to check or reset these values:
5.
Re-enter any User Programs that might have been stored in memory prior to the two-button reset.
6.
The AutoFire®
Kiln Controller is now ready to use again.
If you find that 2 or 3 attempts of resetting the Plog error message does not correct the error code, then
contact Orton. Immediate redisplay of Plog messages may indicate a component failure and unit will
need to be shipped to the factory for repair.
** NOTE: UniTemp™ controllers with firmware earlier than 0031 need the number of relays
reset to 3. If not, the controller will cycle all relays at the same time and kiln will not have uniform
temperature priority. Refer to Level 2 Options to view version number of your controller if you
are unsure.
