RampMaster II Error Messages
The RampMaster II monitors each firing and compares performance to a set of standards. If the firing does not meet performance standards the
RampMaster II automatically stops the firing and displays a corresponding Error Code describing the fault. Pressing any key at this point, displays the
elapsed time and temperature at which the error occurred. Make note of these values before clearing with the START/STOP key. Below is a list of error
codes and their conditions.
As noted on page 16 of this manual, there is a select group of Error Code standards that can be disabled. Normal ceramic work sometimes knowingly
violates the error parameters so we allow these particular error codes to be disabled if desired. These codes are identified below.
E– 0
Software error.
General control failure.
E– 1
Ascending ramp rate is less than 12°F per hour. Rate of rise is examined every 7-1/2 minutes. Condition must persist for 22-1/2 minutes
before the error is triggered. This error code is disabled when Error Codes are turned off.
Probable causes are Control Relay Failure, Element
Failure or Low Supply Voltage.
E– 2
While holding at programmed temperature, chamber temperature is above programmed hold temperature by 50+°F. Condition must persist for
19+seconds before error is triggered. This error code is disabled when Error Codes are turned off.
Probable cause is Control Relay Failure.
E– 3
While holding at programmed temperature, chamber temperature drops below programmed hold temperature by 50+°F. Condition must persist
for 19+ seconds before error is triggered. This error code is disabled when Error Codes are turned off.
Probable causes are Control Relay Failure,
Element Failure or Sudden Drop in Supply Voltage.
