CONSOLE DIAGNOSTIC TESTS
Tach Test
If you do not have resistance, perform the tach test. The tach test will tell you the
tach signal, in revolutions per minute (RPMs), picked up by the console.

A
I. [
61, [ 61, [ENTERI. The consol~
will
dis~lay
"TAR TACH ACT". The target tach speed of 2000 RPMs will be shown

2.
Start stepping on the pedals. The number in the right hand comer of
the console should increase to 2000 RPMs (+/. 200). If the tach signal
picked up by the console is less then 1900 RPMs then there is a
problem in the AC tach circuit - either with the console software,
alternator (check the AC tach wire, the field wir , the diode, and the
terminal posts), or the main cable.
Error Reporting
The console will display various error messages in the display window. The total
amount of errors will be displayed in the upper right numeric window. Note that
only the highest priority reported error will be displa ed. Errors are handled in
two ways. One as a non-fatal "WARNING" which will display the text message
but continue system operation until the user presse the [CLEARI key. The
second way is as a fatal "ERROR" which will stop the exercise and return the
system to an idle intensity state. The console will display the error text and not
let the user restart the programs unless power has been turned off and then back
on.
The following microprocessor errors require a console replacement;
ALU ERROR. TIMER ERROR. and STATIC RAM ERROR.
Resetting the power may clear the following microprocessor errors; EEPROM
ERROR. and PROGRAM ERROR. If resetting the power doesn't work, the console
may need to be replaced.
