E19 – NOVRAM Failure
OVERVIEW
If the values stored in non-volatile memory are out of limits or do not match the safety check
value stored in non-volatile memory a NOVRAM failure occurs. The system attempts to re-
initialize the non-volatile memory three times and if the NOVRAM check fails all three
attempts a NOVRAM failure error (E19) is called.
CORRECTIVE ACTION
An E-19 error indicates the NOVRAM has critically failed and needs to be replaced. If an E19
error occurs the console should be reprogrammed with the current software version and the
power should be toggled. If this does not clear the E-19 error the console PCB will need to be
returned to DCI for repair.
OPERATION ERRORS
E16 – Stuck key error
OVERVIEW
If a key press is detected for more than 45 seconds a stuck key error is flagged. This error is
primarily caused by a faulty keypad but could be caused by other issues (object on the
keypad).
CORRECTIVE ACTION
Reset system power. If error re-occurs replace the keypad with a known good keypad. If
error still occurs replace console PCB with known good console PCB.
E18 – Safety switch test failure
OVERVIEW
If the actual speed exceeds limit set for safety switch test a safety switch test failure error
occurs..
CORRECTIVE ACTION
Re-calibrate system as listed in system calibration section of this document and re-run safety
switch test. If system still fails safety switch test run speed feedback issue and speed control
issue tests in the corrective action procedures section of this document.
