E16 - Stuck Key Error; E18 - Safety Switch Test Failure; E19 - Novram Failure - Vision Fitness T9800S Engineering Manual

5.4 SYSTEM OPERATION ERRORS
System operation errors indicate the system or software is malfunctioning in an unexpected way. These errors require
a power down reset (unplugging) in order to clear. Some of these errors may reoccur once power is applied (e.g.
stuck key error) until error source is resolved (e.g. replace keypad).
5.4.1 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.
5.4.2 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.
5.4.3 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 Vision Fitness for repair.
