Kiln Maximum Temperature has been exceeded! Firing is aborted…
This condition can occur during a firing. If this alarm is presented, the kiln temp has exceeded the maximum defined kiln temperature. The default value for Glass Mode is 1700F. The default value for Ceramic Mode is 2300F. If this error condition is met, the controller will abort the firing and disable all outputs. This condition can occur due to:
- A user programming a schedule with a firing temp exceeding the max temp
- A latched relay resulting in continuous power application to the heating elements
Kiln is failing to cool! Firing is aborted…
This condition can occur during a firing. If this alarm is presented, the controller has determined that the kiln is not cooling. If this error condition is met, the controller will abort the firing and disable all outputs. The condition can occur due to:
- A user defined temperature that is below the room’s ambient temperature
- A latched relay resulting in continuous power application to the heating elements
A high temperature deviation from the hold temp has occurred! Firing is aborted…
This condition can occur during a firing. If this alarm is presented, the controller has determined that the current temperature is greater than 50°F above the current setpoint. If this error condition is met, the controller will abort the firing and disable all outputs. The condition can occur due to:
- A user has opened the kiln during a hold for an extended period of time, resulting in the kiln attempting to generate significant heat to maintain the loss of temperature. (Avoid this by only opening the kiln for short periods if necessary).
- A latched relay resulting in continuous power application to the heating elements.
- An excessively high ramp rate to a low setpoint. This condition can result in significant overshoot, thus triggering the alarm. (Avoid this by using a slower ramp rate to avoid overshoot)
Kiln is failing to heat for too long. Firing is aborted…
This condition can occur during a firing. If this alarm is presented, the controller has determined that the kiln is not heating or the input is invalid. If this error condition is met, the controller will abort the firing and disable all outputs. The condition can occur due to:
- Disconnected Thermocouple
- Thermocouple not present
- Failed Thermocouple
- Failed Element(s)
- Failed Relay(s)
- Insufficient power supply
- Setpoint temperature greater than capability of kiln
