C) Are any tones generated when the problem occurs?
• The CruiseCommand system is capable of producing five dif-
ferent tones in order to alert the operator of a potential prob-
lem. Identifying these tones will dramatically narrow down
the possible cause of the problem.
1.
Slow Repetitive Rate Tone
, also referred to as the "Initialization Tone" is nor-
mal when DC power is first applied to the CruiseCommand System. This tone
indicates:
• Power has just been applied to the System
• The Software Program is running normally
• The Processor is commanding the throttle to Idle and the clutch to
Neutral.
2.
Repetitive Signal: One Long - Three Short
is used to indicate an invalid
command signal at the Station-in-Command Control Head.
3.
Steady Tone
is an indication that something has gone wrong within the Con-
trol System. Typically this tone will be accompanied by an Error Message on
the Processor’s Display.
4.
Repetitive Signal: One Long
- One Short
is used to indicate some type of
malfunction with one or more of the Clutch or Neutral Solenoid Circuits. This
tone will be accompanied by an Error Message on the Processor’s Display.
This tone is only available if the High Side Driver Fault is Enabled.
5.
Three Second Steady Tone
is generated when a fault is detected with the Troll
ON/OFF Solenoid or the Troll Proportional Solenoid. Typically this tone will
be accompanied by an Error Message on the Processor’s Display. This tone is
only available if the High Side Driver Fault is Enabled.
•
Are any Error Messages shown on the Processor’s Dis-
play?
In addition to generating a tone, if at any time the sys-
tem malfunctions or detects a fault, an error message will be
displayed. Write down the Error Message Number and have
available for the ZF Mathers Representative.
D)Are the Control Head(s) LED’s lit or not?
• The LED(s) will be in one of four states
1. Lit Steady
2. Not Lit
3. Blinking Slowly
4. Blinking Rapidly
• When the LED is
Lit Steady
, this indicates that the Station is
in command and in the normal operative mode.
